Polypropylene dishes benefits and harms

We figure it out together: the harm and benefits of plastic dishes

Today we cannot imagine our life without plastic: disposable dishes, food containers, bottles from it are in every home. But it destroys our health! Research on this topic was conducted by the program “Conspiracy Theory. Plastic and Food: Safety Rules ”.

American scientists claim: 80% of the "plastic" substances found in the human body get there mostly from dishes. But if it says "food grade plastic", then it must be harmless! However, there are many nuances, and the main one is that food grade plastic can be different. How it can be used depends on what substances it contains. Unfortunately, this is not written on the labels, and, accordingly, this rule is rarely followed.

An irreplaceable thing in the country, and especially at a picnic with barbecue. In some fast food cafes, soups and second courses are served in plastic bowls and plates. But often such dishes are made of polystyrene (PS). When heated, it forms carcinogenic styrene, which accumulates in the liver and kidneys and can even lead to cirrhosis. Cookware with the PS label may only be used with cold dishes! The only plastic that is suitable for hot food is polypropylene (PP).

Food myths and truths

Alcohol is a solvent, so if you pour it into a plastic cup or a glass, you get a solution of ethanol with stinol, phenol and formaldehyde. This leads to vision, kidney and reproductive problems. Tea, coffee can only be poured into glasses with PP marking, but only when the drink has cooled down a little. Polypropylene can withstand temperatures no higher than 75 degrees.

Most often they are made from PET plastic. Rospotrebnadzor is in favor of banning the sale of beer in PET bottles, since phthalates enter the drink under the influence of alcohol from plastic. They affect hormonal balance, men produce female hormones, decrease sexual activity, women develop endometriosis and infertility.

9 things in the house that indicate you're a slob

1. Ideally, give up plastic altogether. Buy disposable paper dishes, glass containers for storing food, drinks in glass, carry a reusable flask of water with you.

2. Pour only water into disposable plastic cups.

3. Do not reuse disposable tableware and PET water bottles.

4. Do not store acidic foods (tomatoes, fruit salads) in plastic containers. Do not put hot food in it.

5. Wash the containers gently, without damaging the surface layer, diluted with water until mushy with soda.

In Austria, Ireland, Australia, China, Bangladesh and other countries, the use of plastic bottles is completely prohibited

1. PET (E) / PET - polyethylene terephthalate: bottles for drinks, containers for bulk food. The best plastic for bottles.

2. PEHD (HDPE) / HDPE - polyethylene low pressure: for packaging milk, bags. May release formaldehyde.

3. PVC / PVC - polyvinyl chloride: packaging of water, products by small enterprises. Contains the carcinogen vinyl chloride, which can enter food and the human body. Better not to use.

4. PELD (LDPE) / LDPE - polyethylene high pressure: bags, bendable packaging. May release formaldehyde.

5. PP / PP - polypropylene: hot dishes, cling film. Withstands temperatures up to 75 degrees.

6. PS / PS - polystyrene: disposable tableware. Cannot withstand heat. You cannot eat and drink hot meals and drinks and alcohol from it.

7. O (ther) / Other - a mixture of plastics or polymers not specified above. Better not to use on food.

The harm of plastic dishes and how they are labeled



Plastic has taken its place in our kitchens, with various plastic bowls, storage containers, bakeware, plates and cups appearing on the shelves. From plastic we drink, eat, store food in it, heat food in the microwave. Nowadays, in some European countries, up to 70% of residents eat at home from disposable dishes.

The high popularity of plastic dishes is due to the fact that they are convenient, lightweight and cheap, and if they are disposable, there is no need to wash them.

Signs on plastic dishes

For sorting plastic, an international marking was developed, a triangle formed by arrows with a number inside. Under the triangle, together or instead of a number, the letter code of the plastic can be indicated. Plastic packaging is divided into 7 types.

Polyethylene terephthalate PET (E) or PET is used for the production of disposable bottles for:

• water,
• soda and beer,
• cosmetic products,
• dairy products,
• vegetable oils.

Reuse completely prohibited may release phthalates.

High pressure polyethylene PEHD (HDPE) or LDPE is used for the production of:

• packing bags,
• garbage bags,
• packaging for milk.

May release carcinogenic formaldehyde.

Polyvinyl chloride V, PVC or PVC is used for the production of:

• finishing and building materials,
• shoes,
• furniture,
• water bottles,
• medical products,
• films for wrapping products.

This plastic is virtually non-recyclable. May release phthalates on contact with fatty or hot foods, heavy metals, and vinyl chloride.

Low pressure polyethylene PELD (LDPE) or HDPE is used for the production of:

• bottles for detergents,
• pipes,
• toys,
• bags and films for wrapping products.

May release formaldehyde.

Polypropylene PP or PP is used for the production of:

• glasses and jars,
• medical products,
• dishes for hot dishes,
• packaging cling film,
• containers for products.

May release formaldehyde

Polystyrene PS or PS is used for the production of:

• glasses for hot drinks (similar to polystyrene),
• food trays (similar to foam),
• cups for dairy products,
• electrical insulating film,
• food containers,
• forks and spoons.

May release the chemical estrogen and carcinogen styrene.

Polycarbonate and other plastics O, OTHER or OTHER, are used for the production of:

• baby bottles,
• multilayer packaging,
• combined plastic,
• refillable water bottles.

May release bisphenol A.

The harm of plastic dishes

Studies have shown that plastics can be hazardous to health. Harmful substances from plastic begin to get into food already at the smallest heating, and often at room temperature.

Polyethylene terephthalate (PET)

Disposable fast food cups and plates are made from polyethylene terephthalate (PET). It must not be used in the microwave or filled with hot food. PET dishes have a shelf life of one year, after which harmful substances may begin to be released, as a result of this, you cannot stock such dishes for future use.

Polystyrene (PS)

Polystyrene (PS) cookware also does not like high temperatures and is intended for cold food and drinks.

Polypropylene (PP)

Cookware made of polypropylene (PP) can withstand high temperatures, so you can heat food in it in the microwave. A glass of hot tea can be held in your hand and will not be hot. A big disadvantage of this dish can be considered its not love for fats, when in contact with them, polypropylene collapses and releases toxic substances.

Polycarbonate (PC)

Polycarbonate (PC) cookware, the safest and most practical. It looks like ceramic or porcelain dishes. Polycarbonate cookware, non-crushing and non-oxidizing. Storage containers and baking dishes are made from it.

Silicone

Silicone cookware will cope with temperatures from –60 to +280 degrees. Jelly and ice cupcake molds are made from this material. Silicone dishes are soft, very slippery and non-stick, so they do not need to be greased before use.

Bisphenol A and phthalates

Polycarbonate baby bottles have replaced glass ones. But not everyone knows that bisphenol A (BPA), which is used in the production of polycarbonate, can come from polycarbonate in a liquid.

BPA is very similar to female sex hormones in that it interferes with normal hormones and promotes obesity, breast cancer, heart disease, and diabetes. In particular, it is dangerous for the development of the boy's reproductive system when he is in the mother's stomach.

In the United States, they even banned the use of baby bottles in the production of which they used bisphenol.

Three years ago, Canadian scientists made the first warnings about the dangers of BPA. They proved that a substance used in making plastic dishes causes changes in the brain and puts the body at risk of breast or prostate cancer.

Phthalates also need to be included in the list of toxic substances that can pass into fats from plastic dishes. They give plastics elasticity. Phthalates are as toxic as bisphenol. They are in films in which they pack sausages, cheese and other products.

Safe use of plastic dishes

Having brought food from the store, they must be immediately transferred from the packaging to glass metal or ceramic dishes.

If you use plastic dishes at home, then only for cold food and water, since when making coffee or soups, the water heats up to 100 ° C. And according to GOST, the dishes are tested at temperatures up to 75 ° C, which means that the tests are softer true circumstances in the kitchen.

For cooking and for hot food, you can only use burnt dishes in which the surface is glazed, and due to this it has become inert to food. Stainless steel and glass also behave passively.

Labeling of plastic dishes: the harm and advantages of plastic

In the summer, plastic dishes are gaining popularity. It is quite convenient to transport food in it. As a rule, such things are used on long trips and at picnics. The undoubted advantage of such dishes is their low cost. It's no secret that in most cases it is disposable. Labeling of plastic dishes can tell a lot about their quality. After reading our article, you can easily determine what exactly the signs mean, which are located at the bottom of a disposable plate or glass.

The history of the creation of plastic dishes

Today, disposable plastic dishes are quite familiar to us. We use it as a lunch box or take it with us to a picnic. Does everyone know exactly when she appeared? You can find out this information in our article.

For the first time, they learned about plastic dishes in the United States of America in 1910. The first was a disposable glass, and then they began to produce forks, plates, spoons and other objects known to us today. The first dishes were made of thick paper. She only gained popularity in 1950. And it was at this time that the paper began to be replaced with another material, namely plastic.

Plastic dishes in the USSR. Nowadays

In the Soviet Union, such dishes began to appear only in 1960, but until 1990 they were not popular. This was due to the lack of fast food establishments. It is worth paying attention to the fact that now it is paper disposable tableware that is gaining popularity again. This is no coincidence, because quite often plastic products for food storage do not meet quality standards. Paper, in turn, is a safe and environmentally friendly material.

To purchase utensils that are harmless to health, you need to know what the markings on plastic dishes mean. You can find out this and much more in our article.

Plastic dishes have a mass positive qualities... The very first thing consumers pay attention to is the low cost of such a product. It is easy to transport and does not need to be washed. It is known that plastic dishes are strong enough, but only if there is no excessive stress on them. As a rule, due to its positive qualities, it is used at picnics, parties, or simply take food in it to work or on a long trip. The labeling of plastic food containers can tell a lot about their quality and recommendations for use. In order for a disposable food container to bring only benefits, you need to know how to use it correctly.

Today many cafes and fast food restaurants use plastic disposable tableware because it is cheap, convenient and aesthetically pleasing. It should be noted that containers for reusable use are also created from this material. Many housewives use them for storing bulk substances. Is plastic harmful? You can find out this information in our article.

Harm and negative qualities of plastic and disposable tableware

Few people know, but not correct use any disposable container may cause irreversible harm to health. In order to prevent this from happening, you need to know what the labeling of plastic dishes means. The decoding of markers is provided in our article.

Reusable and disposable tableware is harmful if used incorrectly. However, some doctors believe that it carries a certain danger under all circumstances. First of all, experts do not recommend reusing those containers that are intended for single use. In the second application, it releases a large amount of substances hazardous to health.

It's no secret that plastic is a material that is obtained by chemical means. For this reason, when exposed to different products, it can behave completely differently. For example, you cannot drink warm tea from any disposable glass. Labeling plastic dishes is a great way to figure out how a container can be used.

Plastic is known to be poorly degradable. This process takes over ten years. It is for this reason that this material negatively affects our ecology. To cope with this problem, factories are opening in many cities that process materials hazardous to nature. Unfortunately, there are few such enterprises. It is for this reason that many fast food establishments prefer to use only paper dishes. It is more environmentally friendly and harmless.

Plastic markings. Polystyrene utensils

In order not to harm your health, you need to know what the marking on plastic dishes means. The decryption, which is described in our article, is easy to remember. Such information will definitely come in handy for you at a picnic or a party, and will also help keep your health.

If there is a PS sign on plastic dishes, you can be sure that such containers include polystyrene. It is extremely hazardous to health if misused. Plastic containers marked with this mark should only be used for storing chilled food. The thing is that when in contact with hot food, a container with polystyrene releases styrene, which accumulates in the vital organs. Over time, this can lead to the development of serious diseases. It is also highly discouraged to store alcoholic beverages and heat food in the microwave in such dishes.

Polypropylene plastic tableware

Are there plastic utensils for the microwave? The marking and its decoding, which is described in our article, will allow you to find out.

There is an opinion that disposable dishes should never be used in the microwave. However, it is not. On some plastic containers, you may find a sign with the number 5 and PP symbols. This marking indicates that the cookware contains polypropylene. It is in such a container that you can heat food in the microwave and pour hot tea into it. Few people know, but polypropylene dishes do not deform when in contact with contents, the temperature of which is no more than 100 degrees Celsius.

The only thing that should never be stored in such a container is alcohol. If alcohol was poured into a polypropylene dish, the plastic begins to release phenol, from which a person can completely lose his sight. The polypropylene container has a lot of positive qualities. It is known that it is quite durable and retains heat well. Today, plastic dishes are extremely popular. Consumer labeling is the main source of information that allows you to find out what this or that container is intended for.

What does the triangle of three arrows mean on plastic containers?

We know what the markings look like on plastic dishes. In addition to numbers and letters, there is a triangle sign on it, which consists of three arrows. Not everyone understands what he means. Such a closed loop of arrows indicates that the used dishes are subject to further processing. As a rule, there is a number inside the triangle, and several letters below it. They can tell you about the material from which your chosen cookware is made.

Sign with cutlery

The labeling of plastic dishes is the first thing a consumer should pay attention to when buying. As we said earlier, if containers are misused, they can cause irreversible harm to health. Often on plastic dishes you can find a sign depicting cutlery. Such a marker indicates that this container can be stored food products... If this sign is crossed out, then you can be sure that the product is not intended for use in the kitchen.

To protect yourself and your loved ones, you need to know and remember what the labeling of plastic dishes means. The decryption, which is described in our article, will allow you to find out what is included in a particular container.

If you went to a picnic with plastic dishes, then in no case burn it after it ends. When burning, disposable containers release substances hazardous to health. Experts strongly advise against eating in establishments that use plastic dishes. If you have no other choice, then be sure to pay attention to its quality. Labeling of plastic dishes will allow you to find out if it is used correctly in a particular institution. A similar situation is with coffee machines. Often, with a great desire to save money, they use cheaper glasses that are not intended for storing hot drinks.

As we said earlier, never reuse disposable tableware. This rule is not accidental, because in this case, the top layer is destroyed on the surface of the plastic container, and it begins to release life-threatening chemicals.

Doctors-gastroenterologists strongly discourage the use of plastic dishes. They emphasize that under any circumstances, some of the polymers still enter the human body. They are known to accumulate over time and become causative agents of serious diseases. Experts strongly recommend not to use disposable containers, or at least pay attention to the recommendations for its use. Labeling plastic dishes will allow you to find out what a particular container is suitable for. Doctors recommend today to abandon the use of such kitchen items and use only the disposable container, which is made of thick paper.

The harm of plastic dishes

What is plastic

Plastic or plastic Organic material based on natural or synthetic high molecular weight compounds. The most popular in use is plastic made on the basis of synthetic polymers.

The most common polymeric materials (types of plastic):

• Polyvinyl chloride (PVC)
• Polypropylene
• Polyethylene
• Polystyrene
• Polycarbonate

They are used to produce both technical and food grade plastics.

The plastics used for the production of products in contact with food and children's assortment must undergo an examination for compliance with sanitary and hygienic standards and are certified. The manufacturer is obliged to label his products. Food grade plastic has a generally accepted label - "glass and fork". It may be written on it that it is intended for cold, bulk or hot products, for use in microwave oven or for freezing, sometimes the temperature range is indicated.

Labels on plastic containers indicate when they can be used

For example, "Snowflakes" indicate that the container is suitable for freezing food, "a wave oven" - that the dishes can be heated in the microwave, and "plates in the shower" indicate that the containers can be washed in the dishwasher. This marking is also used by some Russian manufacturers.

The harm of plastic

Pure plastic is quite fragile, fragile material - it cracks in the light, melts from heat. For strength, stabilizing substances are added to it. This makes the plastic stronger, but also more toxic. Because of this, the harm of plastic dishes is manifested.

By themselves, polymers are inert, non-toxic and do not "migrate" into food. But here intermediate substances, processing aids, solvents, as well as chemical decomposition products can penetrate into food and have a toxic effect on humans. Under certain conditions, plastic releases toxic compounds that, when entering the human body, negatively affect its health.

Decay products are released from plastic dishes over time

This process can take place while food is being stored or heated. In addition, polymeric materials are subject to change (aging), as a result of which degradation products are released from them. Moreover different kinds plastic becomes toxic when different conditions - some should not be heated, others should not be washed, etc. Improper use becomes the main cause of harm to plastic dishes.

American scientists claim that up to 80% of the "plastic" substances found in the human body get there from construction and finishing materials, in particular, from such popular plastic windows, furniture, but most of all - from dishes: from food-grade plastic all kinds of compounds pass into food. Domestic manufacturers assure that certified plastic dishes are absolutely safe - if used for their intended purpose.

Pros of plastic dishes

Compactness, lightness, hygiene, low cost, ease of use allow the use of plastic dishes outside the house - on the road, in nature, etc. It does not require washing or cleaning. Therefore, the demand for the use of plastic tableware is growing. Fast food restaurants, summer cafes and snack bars also use plastic dishes.

Plastic dishes are very popular because of their low cost

Plastic food utensils: how to use

So that plastic dishes do not harm your health, they must be used strictly as intended. Different brands of food grade plastic have different properties. One brand of this polymer raw material is intended for the production of bottles for water, the other is for bottles of carbonated drinks. The yoghurt cups are made of plastic of a brand that allows the molded to make a lightweight, cheap container that is neutral to milk fat, and the pudding cups must resist sugar.

Experts insist: in no case should you use plastic packaging as containers for storing food, and disposable tableware - multiple times. Disposable packaging should only be used one time.

How plastic will react to contact with ingredients for which it was not intended, what compounds can be formed in this case, no one has investigated. Especially insidious are fats and acids, which can draw free toxic compounds from plastic.

Foods that are high in sugar and fat should not be cooked in plastic containers. They heat up to the melting point and deformation of the plastic. You need to cook them in a special dish that can withstand heating to 140, 180 and more C.

Observe temperature markings when using plastic utensils

When disposable plastic tableware is reused, its outer protective layer is damaged, and carcinogenic substances - formaldehydes, phenol, cadmium, lead - are released.

Do not drink alcohol from disposable plastic glasses. Any plastic contains toxic substances that do not dissolve in ordinary cold drinks, but cannot withstand the chemical attack of alcohol.

The release of all kinds of compounds from plastic is greatly enhanced by heating. Therefore, only specially designed containers can be used in the microwave oven.

At home, immediately remove the plastic wrap from the food. Peel off the top layer from food stored in plastic wrap.

Do not use disposable packaging for storing food. Store food in glass and ceramic containers. Try to avoid plastic-packed foods as much as possible, preferring bulk foods.

Buy baby food only in glass or cardboard. Do not use for baby food plastic dishes. Do not microwave food in plastic containers.

Do not keep water in jug filters for long periods. Replace the remaining water in the morning and evening with fresh water. Throw away any cloudy plastic water jug.

Also, disposable packaging was not intended for washing, so the result can be unpredictable.

Any polymer material ages under the influence of light, heat, heat and contact with all kinds of substances. Then it becomes cloudy, absorbs odors and ingredients from the contents and releases toxic substances.

Food manufacturers point out that shelf life refers not only to the product itself, but also to the packaging. This is most important for canned food. For example, they can contain a toxic substance - biphenol.

Plastic sheeting containing biphenol lined the inner surface cansso that the metal does not come into contact with food. From here, the biphenol can pass into the contents.

It is advisable to replace canned food with fresh or frozen food.

Transfer food from opened cans to glass containers, even if we are talking about short-term storage (under the influence of oxygen, the corrosion of cans increases sharply and the content of lead and tin in food begins to increase rapidly).

Toxins can accumulate in the body for years, undermining health. Even a small amount of them is poisonous if exposed for a long time.

Buy food, plastic dishes, and cling film only from reputable manufacturers and only in trusted stores.

Today, there are disposable tableware made from environmentally friendly materials - cane, bamboo, based on eggshell, as well as cardboard paper dishes.

An alternative to plastic today is environmentally friendly disposable tableware

ADDITIONALLY

Labeling of plastic dishes

To simplify sorting of plastic, a special international marking has been developed - triangles formed by arrows with a number inside. The number indicating the type of plastic is located inside the triangle. Below the triangle is an abbreviation for the type of plastic.

When purchasing plastic dishes, be sure to pay attention to the marking

PET Polyethylene terephthalate: bottles for carbonated drinks, water, juices, dairy products, vegetable oils, cosmetic products, etc.

Frozen ready meals in trays that can be reheated in the microwave or oven are made from crystallized polyethylene terephthalate. Its properties remain unchanged in the range from -40º to + 250ºC. True, some brands may lose the required heat resistance after being deeply cooled.

Buy drinks only in PET bottles and do not reuse them.

PP Polypropylene: medical products, bottle caps, hot dishes, food packaging film

Safer dishes made of polypropylene (PP marking). Polypropylene glass can withstand temperatures up to + 100 ° C. You can drink hot tea or coffee from polypropylene glasses, and you can heat food in a microwave oven in plates. But on contact with strong drinks and alcohol, it releases formaldehyde or phenol. If you drink vodka from such a glass, not only the kidneys suffer, but also the eyesight. Formaldehyde is also considered a carcinogen.

PS Polystyrene: disposable dishes, cups for dairy products, yoghurt, electrical insulating film

Polystyrene is indifferent to cold liquids. But when polystyrene dishes come into contact with hot water or alcohol, they begin to release a toxic compound (monomers) - styrenes. It is not recommended to put hot food in polystyrene plates. Polystyrene plates are often used in summer cafes for barbecue. And along with hot meat and ketchup, the client also receives a dose of toxins - styrenes, which accumulate in the liver and kidneys.

Disposable cups can only be used for water. It is better not to drink sour juices, soda, hot and strong drinks from them. Some vending machines use polystyrene glasses. That is, you cannot drink hot coffee or tea from them.

When purchasing instant food (those that only need to be poured with boiling water), pay attention to the packaging (glass, bag, plate). Although Rospotrebnadzor and certification bodies monitor the safety of materials, nevertheless, manufacturers often use polystyrene packaging. Therefore, it is better to transfer food to ceramic or enamel dishes and then pour boiling water over.

Refrigerate food before placing it in the container. Use only special cookware for hot food and microwave ovens.

Pans marked with PS are only intended for cold liquids

If there is no marking on the plastic, you can distinguish PS from PP by touch - polystyrene crunches and breaks, and polypropylene crumples. Also the main distinctive feature polystyrene bottles - bluish color of the container. And when you press your fingernail on the PS plastic, a whitish scar (strip) always remains, on the PP plastic - the container will remain smooth.

HDP Polyethylene high density: packing bags, garbage bags

PVC Polyvinyl chloride: construction and decoration Materials, furniture, footwear, medical products, water bottles, food packaging film

The synthetic poison dioxin can be released from PVC dishes in cases of heating food in microwave ovens, freezing water in freezers. Dioxins accumulate in human adipose tissue and are not excreted from the body for a very long time (up to 30 years). Released dioxin causes cancer (especially breast cancer).

LDP Low density polyethylene (low pressure): bottles for detergents and edible oils, toys, pipes, plastic bags.

Other types of plastic are multilayer packaging or composite plastic.

Mayonnaise, ketchup and other sauces, condiments, juices, jams, ready-to-heat soups and cereals, sold in bags. Such bags are made from multilayer combined films. The choice of film depends on the properties of the product, the period and conditions of its storage. Soups, cereals, second courses are packed in bags made of films with a high melting point. Dishes in such packaging can be heated in the microwave or boiled directly in the bag. Such dishes can withstand temperatures from -40 to + 230 ° C and more. But physiologists still advise eating them less often.

Tableware made of melamine (polymerized formaldehyde) - it is white, shiny (reminiscent of porcelain), weighs lighter, does not break. When tapped, melamine dishes emit not a ringing, but a dull sound.

Dangerous melamine products are very common in children's utensils.

It is extremely dangerous to use such utensils. For the strength of the dishes, asbestos can be added to it, which is prohibited even in construction (such dishes come to Russia from Turkey, Jordan and China). It cannot be used for hot food. When hot water is poured into a melamine dish, formaldehyde begins to dissolve in the water. Formaldehyde and asbestos can cause cancer. To keep the drawing on such a plate for a long time, paints containing heavy metals, primarily lead, are used.

“Disposable tableware frees up our time, makes life easier and easier. It is lightweight and comfortable and does not need to be washed. But any plastic tableware has an adverse effect on our health, which does not cause tangible problems if it is used rarely (when it is really necessary), ”says nutritionist Tatiana Fialkova.

The constant use of plastic leads to poor health. The fact is that unscrupulous manufacturers from time to time release on the market plastic dishes made of low quality materials, and even with prohibited additives. In general, it is worth remembering that disposable dishes are called so because they cannot be used a second time, but we often do not pay attention to this prescription. Plastic disposable dishes cannot be washed or disinfected: all the infection that gets on it persists and multiplies, passing on to everyone who uses this dish. When disposable plastic tableware is reused, its outer protective layer is damaged, and carcinogenic substances - formaldehydes, phenol, cadmium, lead - are released. Toxins can accumulate in the body for years, affecting health. Even a small amount of them is poisonous for us if it is exposed for a long time.

Under no circumstances should plastic utensils be used as containers for storing food, and disposable utensils should not be used multiple times. How the plastic will react to contact with ingredients for which it was not intended, what compounds may be formed in this case, it is difficult to imagine. Especially insidious are fats and acids, which can draw free toxic compounds from plastic.

What to look for when choosing plastic cookware?

When buying disposable tableware, you need to be clear about what you will use it for. Plastic is a rather fragile material that can crack in the light and melt in the heat. For this reason, manufacturers add stabilizing substances, thanks to which the plastic becomes stronger, but, alas, more toxic. The marking is the designation of the contained stabilizer. She helps make right choice... For example, food grade plastic is commonly labeled as “glass and fork”. It may say that it is intended for cold, bulk or hot food, for use in a microwave oven or for freezing, sometimes a temperature range is indicated.

PS or ABC plastic is polystyrene. Plastic dishes made of this material are safe only in contact with cold foods (at temperatures above +40 - it turns into poison). But pouring alcoholic drinks, hot tea / coffee, sour juices into glasses is strictly prohibited. Do not store sour foods, cabbage, pickles cucumbers, because the toxic substance styrene is released, which accumulates in our liver and kidneys, gradually disrupting their function.

PP or PP is polypropylene. With such dishes you can eat hot and freeze (temperature range from -40 to +140). It is permissible to heat food in the microwave in it. A glass of hot tea can be held in your hand and will not be hot. The big disadvantage of this dish can be considered its not love for fats, when in contact with them, polypropylene is destroyed and releases toxic substances. Dishwasher safe and microwave safe. But it is worth noting that not only packaging, plates, but even glasses for alcohol-containing liquids are made of such material, and alcohol cannot be drunk and stored in such a container, since carcinogenic substances phenol and formaldehyde are released, which "squeeze" vision and impair work kidneys.

RS - polycarbonate dishes are considered the safest and most practical. It looks like ceramic or porcelain dishes. It does not break or oxidize. Storage containers and baking dishes are prepared from it.

PE or PE - polyethylene. The safest plastic option. It is preferable to choose disposable dishes with this marking.

Can plastic dishes be used at sub-zero temperatures?

Dishes are produced specially designed for use in m / in ovens and for freezing food. It says that it is intended for use in a microwave oven or for freezing (for example, "Snowflakes" mean that the container is suitable for freezing food, "a wave oven" - that the dishes can be heated in the microwave), the temperature range may be indicated, those. such utensils must be marked accordingly.

Hello.

Today I would like to talk about the dangers of plastic dishes. Many of us use these utensils to store or transport food. Plastic dishes are very convenient to use, cheap and in many cases considered much more effective than iron or glass dishes.

In our active time, where you need to "spin like a squirrel in a wheel" to achieve something in life, it is not always possible to store food in an iron or glass container (it takes up a lot of space, has a lot of weight and size). People more and more often use plastic utensils, which are very practical and lightweight, allow you to carry food or eat comfortably.

The sales level of plastic tableware is increasing every year. A large number of disposable tableware is produced for various purposes: cups, plates, containers for storing food, etc. Manufacturers declare that their products do not harm human health if the instructions for use are followed. Unfortunately, few of us know these instructions. But in vain ...

What is plastic? By itself, plastic is a brittle polymer material, it is considered non-toxic and does not harm human health. But manufacturers, in order to improve its durability and strength, add special chemical components that, under certain conditions, are harmful to health.

There are many types of plastic dishes. It happens from the material: polypropylene, polyethylene, polycarbonate, polystyrene and polyvinyl chloride. Depending on the composition of the plastic, the product is used for different purposes.

Such dishes must necessarily indicate under what conditions it can be used. The manufacturer puts a special sign on his product, which indicates for what purposes it can be used. The most common signs are: "fork with a glass", "snowflakes", "plates under the shower", etc. ... Such signs inform the consumer that the product is suitable for contact with food and that some kind of exposure to plastic is allowed (for example, washing with water or hot / low temperature).

The manufacturer also indicates the type of plastic. Most often, this is a number in a triangle that indicates what material it is made of. plastic container... Check out the labeling table:

Most often, the mark is placed on the bottom of the cookware. If you want to buy plastic dishes, then be sure to look for the number in the triangle. Let's take a closer look at what harm different types of plastic can cause if used improperly:

HARMFUL PLASTIC DISHES

1. Polyethylene terephthalate (PET) .

This material is considered environmentally friendly among the rest. Manufacturers produce disposable cups, plates, cans, boxes, bottles from it. The shelf life of such a container is a year. Unfortunately, this material has weak protective characteristics. It lets in ultraviolet rays and air, which leads to a decrease in the storage time of products.

Also, the manufacturer can add additional chemical components (dicoli, phthalates or other toxic substances) to improve the reliability indicators of their products. Then already such plastic can harm human health. The main rule is not to reuse PET containers, because over time, the protective properties are lost and toxic substances are released.

Also, when heated, formaldehyde is released, so do not heat polyethylene terephthalate dishes (for example, in a microwave).

Low pressure polyethylene (HDPE).

Get it at low pressure. This material is included in various cans, bottles, films. Predominantly rigid containers. Permitted to be reused. It is safe to say that it belongs to the safest plastics. Has high hardness, high strength, excellent chemical resistance to fats, acids and alkalis. Melting point: + 129-135. Has greater fragility, less water absorption, vapor permeability.



2. High pressure polyethylene (LDPE) .

The material is very lightweight and durable. Various plastic packaging (flexible), bags, films, containers for storing detergents, and some plastic bottles (for vegetable oil) are made from this material. It is considered environmentally friendly for others due to its characteristics. Used for food contact. Melting point is about 110 degrees. It is resistant to tearing and deformation. Resistant to sunlight.

3. Polyvinyl chloride (PVC or PVC) .

Very resistant to acids, various oils, solvents.

Crockery made of this material is very common. They are made of bottles for water, it is also part of some films for packaging. They also make caps for plastic bottles (vegetable oil for example). Dishes containing polyvinyl chloride must not be used for long storage any products.

To create color or impact resistance, manufacturers add additional additives: plasticizers, softeners, pigments, and so on. It is these additives that are dangerous to humans.

If the conditions of use are not followed, hazardous substances are released - phthalates, dioxide, bisphenol A, heavy metals and vinyl chloride (this is a very toxic substance that can greatly harm health). Scientists have proven that when used improperly, vinyl chloride is released, which penetrates into food.

Products made from polyvinyl chloride must not be heated. When burned, toxic substances are released (very dangerous for humans). Hormonal disorders, decreased immunity, cancer, or infertility may occur.



4. Polypropylene (PP).

Polypropylene is used for the manufacture of food packaging films, cups for yogurt, plates, spoons, lids for various containers, baby bottles, containers for hot food. The material can withstand high temperatures (up to +100 C), so you can drink hot tea or coffee.

You cannot drink alcohol from polypropylene, because formaldehyde and phenol are released. These substances accumulate in the body and destroy the liver and kidneys. There is a visual impairment, disruption of the gastrointestinal tract (an ulcer is possible).

Experts also prohibit the use of such utensils for storing fat. On contact with fat, the protective walls of the plastic are destroyed and formaldehyde and other toxic substances are released. It is forbidden to heat products from polypropylene above 100 degrees.



5. Polystyrene (PS).

Manufacturers use this type of plastic to create egg containers and cups. Do not heat polystyrene dishes, because hazardous toxic substances are released. It is highly discouraged to store hot dishes.

The advantage of polystyrene is its resistance to cold, so it can be used for cold food.

In case of improper handling, the release of a carcinogen - styrene is possible. Human reproductive function suffers. You cannot drink alcohol or hot tea from such a container. Cookware is only intended for cold food. It is advisable to minimize the use of this type of plastic in your everyday life.

6. Mix of different plastics (OTHER) .

A mixture of different plastics or polymers not listed above. Packaging marked with this number cannot be recycled and ends up life cycle in a landfill.

Many manufacturers use combinations of different plastics. It is used to make baby bottles, water bottles.

A very common component is polycarbonate. In case of improper handling of dishes (very long-term use), a toxic element, bisphenol A, is released from polycarbonate. Bisphenol A disrupts physiological processes in the body, metabolism is disturbed, and hormonal imbalance occurs. It is not recommended to use plastic dishes with the OTHER mark.

We got acquainted with the main types of materials that are used to create dishes from plastic, we learned what danger they pose in themselves. Unfortunately, in our time, it is almost impossible to do without plastic dishes. Therefore, it is necessary to minimize the harm from their use. Experts recommend the following:

TIPS FOR USING PLASTIC DISHES

1. It is necessary to strictly use plastic utensils for their intended purpose.
2. Do not pour hot water into plastic containers.
3. Do not buy dishes if you see that it was made a year ago (the longer it is stored, the more chemistry you will receive).
4. It is advisable to use only glassware for the child.
5. Avoid plastic baby feeding bottles (buy a glass bottle instead).
6. Do not store food in plastic containers.
7. Buy glass water from the store.
8. Disposable containers are strictly forbidden to be reused.
9. Do not store food in plastic bags in the refrigerator.

Plastic bottles, containers and utensils have firmly entered our life. But simultaneously with "plasticization", there are more and more reports about the danger that this material conceals in itself: under certain conditions, it releases toxic compounds that, getting into the human body, gradually undermine his health.

American scientists argue that up to 80% of the "plastic" substances found in the human body get there from building and finishing materials, in particular, from the so popular plastic windows, furniture, but most of all - from dishes: from food-grade plastic, all kinds of compounds pass into products nutrition. Domestic manufacturers, in turn, assure that certified plastic dishes are absolutely safe. True, they make a reservation: if you use it for its intended purpose.

The most common polymeric materials (or plastics) are polyvinyl chloride (PVC), polypropylene, polyethylene, polystyrene, and polycarbonate. They produce both technical and food grade plastic. By themselves, polymers are inert, non-toxic and do not "migrate" into food. But here are intermediate substances, processing aids, solvents, as well as chemical decomposition products can penetrate into food and have a toxic effect on humans.

This process can take place while food is being stored or heated. In addition, polymer materials are subject to change (aging), as a result of which degradation products are released from them. Moreover, different types of plastic become toxic under different conditions - some cannot be heated, others can be washed, etc.

Dangerous fragility of plastic

Polyvinyl chloride is a chlorine-based polymer. It is distributed all over the world because it is extremely cheap. It is used to make bottles for drinks, boxes for cosmetics, containers for household chemicals, and disposable dishes. Over time, PVC begins to release a harmful substance - vinyl chloride. Naturally, from the bottle it gets into the soda, from the plate - into food, and from there - directly into the human body. And vinyl chloride is a carcinogen. A PVC bottle begins to release this dangerous substance a week after the contents are poured into it. After a month, several milligrams of vinyl chloride accumulate in the mineral water. From the point of view of oncologists, this is a lot.

Often, plastic bottles are reused, tea or fruit drink and even alcoholic drinks are poured into them. On the markets in plastic bottles milk and butter are on sale. Five-liter bottles have replaced buckets and cans for summer residents, and advocates of a healthy lifestyle go with them to springs for "living" water and keep Epiphany water in them for a year. Experts are unanimous: nothing but water can be refilled into water bottles. And even then not all. Only PET bottles can be reused. Toxic PVC is released from PVC bottles.

However, many experts are sure that any bottle plastic remains neutral only in the absence of oxygen, that is, while water retains its original chemical composition... As soon as the bottle is opened, the water quickly changes its properties, after which the plastic inevitably changes its properties. As for the "living" and holy water, its healing properties can only be preserved in glass containers.

How to distinguish hazardous PVC products from safe plastic? It is necessary to examine the bottom. Conscientious manufacturers put an icon - a three in a triangle at the bottom of dangerous bottles. Or they write PVC - this is how PVC is designated in English. But there are few such bottles with honest inscriptions. A harmful container can also be recognized by the influx on the bottom. It can be in the form of a line or a spear with two ends. But the surest way is to press the bottle with your fingernail. If the container is dangerous, a whitish scar will form on it. The “right” bottle remains smooth.

Disposable cups can only be used for water. It is better not to drink sour juices, soda, hot and strong drinks from them! It is not recommended to put hot food in polystyrene plates.

Convenient, practical, but risky

The time for picnics is approaching, and we are stocking up on plastic plates to minimize everyday inconveniences. Pour tea from a thermos or alcoholic drinks into plastic cups. Cheap, practical, but not safe.

Disposable plastic dishes cost a penny. But plastic is a delicate material. It cracks in the light. It melts from the heat. For strength, stabilizing substances are added to it. The plastic is getting stronger and ... more toxic.

Polystyrene (designated by the letters PS) is indifferent to cold liquids. But as soon as you pour a hot or alcoholic drink, the harmless glass begins to release a toxic compound called styrene. Polystyrene plates are often used in summer cafes for barbecue. And the client, in addition to hot meat and ketchup, also receives a dose of toxins.

The Tin Can Mystery

Any polymer material ages under the influence of light, heat, heat and contact with all kinds of substances. Then it becomes cloudy, absorbs odors and ingredients from the contents and releases toxic substances. Food manufacturers point out that shelf life refers not only to the product itself, but also to the packaging. This is most important for canned food. For example, they can contain a toxic substance - biphenol. Plastic wrap containing biphenol is lined with the inside of the cans to keep the metal out of contact with food. From here, the biphenol can pass into the contents. Therefore:

• ditch canned food in favor of fresh and frozen foods.
• transfer food from opened cans to glass ones, even if it is about short-term storage (under the influence of oxygen, the corrosion of cans increases sharply and the content of lead and tin in food begins to increase rapidly).

Follow the labeling

At one time, to simplify the sorting of plastic, a special international marking was developed - triangles formed by arrows with a number inside. The number indicates the type of plastic. Instead of a number or under a triangle, along with the number, you can find the letter code of the plastic:

• PET
  Polyethylene terephthalate: bottles for carbonated drinks, water, juices, dairy products, vegetable oils, cosmetic products, etc.
• HDP
  High density polyethylene: packing bags, garbage bags
• PVC
  Polyvinyl chloride: building and finishing materials, furniture, footwear, medical products, water bottles, food packaging film
• LDP
  Low density polyethylene: bottles for detergents, toys, pipes
• PP
  Polypropylene: medical products, dishes for hot dishes, food packaging film
• PS
  Polystyrene: disposable dishes, cups for dairy products, yoghurt, electrical insulating film
• Other plastics: multi-layer packaging or composite plastics

Expert opinion

Nadezhda Tarakanova, technologist at Bytplast
The plastic used for the production of products in contact with food and children's assortment is subject to mandatory examination for compliance with sanitary and hygienic standards and is certified. And if a manufacturer declares, for example, that a product is intended for drinking water, then it is tested as a container for drinking water. The manufacturer is obliged to label his products. Food grade plastic has a generally accepted label - "glass and fork". It may say that it is intended for cold, bulk or hot food, for use in a microwave oven or for freezing, sometimes a temperature range is indicated. "Snowflakes" indicate that the container is suitable for freezing food, "the oven with waves" - that the dishes can be heated in the microwave, and "plates in the shower" indicate that the containers can be washed in the dishwasher. This marking is also used by some Russian manufacturers, including us.

Polypropylene glass (marking - PP) can withstand temperatures up to + 100 ° C. But it does not tolerate a chemical attack - it releases formaldehyde or phenol. If you drink vodka from such a glass, not only the kidneys suffer, but also the eyesight. Formaldehyde is also considered a carcinogen.

Disposable packaging - one time only

Buy food, plastic dishes, and cling film only from reputable manufacturers and only from trusted stores.

In order for plastic dishes to be safe, they must be used strictly for their intended purpose. Different brands of food grade plastic have different properties. One brand of this polymer raw material is intended for the production of bottles for water, the other for bottles of carbonated drinks. The yoghurt cups are made of plastic of a brand that allows the molded to make a lightweight, cheap container that is neutral to milk fat, and the pudding cups must resist sugar.

Therefore, experts insist: in no case should you use plastic packaging as containers for storing food, and disposable tableware - multiple times. How plastic will react to contact with ingredients for which it was not intended, what compounds can be formed in this case, no one has investigated. Especially insidious are fats and acids, which can draw free toxic compounds from plastic.

There is one more important point. The plastic container must be washed before reuse. The single-use packaging was not intended for washing, so the result is unpredictable.

The release of all kinds of compounds from plastic is greatly enhanced by heating. Therefore, only special containers can be used in the microwave.

• Store food in glass and ceramic containers.
• Try to avoid plastic-packed foods as much as possible, give preference to products by weight.
• Peel off the top layer from food stored in plastic wrap.
• At home, immediately remove the plastic wrap from the food.
• Buy drinks only in PET bottles and do not reuse them.
• Buy baby food only in glass or cardboard.
• Do not use plastic dishes for baby food.
• Do not microwave food in plastic containers.
• Do not keep water in jug filters for long periods. Replace the remaining water in the morning and evening with fresh water.
• Throw away the cloudy water jug.

Flexible packaging

Mayonnaise, ketchup and other sauces, spices, juices, jams, as well as ready-made soups and cereals that require reheating are sold in packets - regular or "standing". Such bags are made from multilayer combined films. The choice of film depends on the properties of the product, the period and conditions of its storage. Soups, cereals, second courses are packed in bags made of films with a high melting point. Dishes in such packaging can be heated in the microwave or boiled directly in the bag. But physiologists advise eating them less often: the less chemistry in life, the better.

When purchasing instant food (those that only need to be poured with boiling water), pay attention to the packaging (glass, bag, plate). Although Rospotrebnadzor and certification bodies monitor the safety of materials, manufacturers nevertheless often use polystyrene packaging. And when it comes into contact with hot water, it begins to release harmful monomers - styrenes. Therefore, it is better to transfer food to ceramic or enamel dishes and then pour boiling water over.

Frozen ready meals in trays that can be reheated in the microwave or oven are made from crystallized polyethylene terephthalate. Its properties remain unchanged in the range from -40º to + 250ºC. True, some brands may lose the required heat resistance after being deeply cooled.

Do not reuse disposable food packaging or recycle disposable tableware. Refrigerate food before placing it in the container. Use only special cookware for hot food and microwave ovens.

Small doses are big problems

How to determine acceptable and safe doses chemical substances? Scientists differ. Some argue: if you do not exceed the permissible level, there will be no harm. It is necessary to eat more than 2 kg of canned food a day to get closer to the maximum allowable dose. Others insist: the more chemicals a person consumes, the more he destroys the body. If there are no symptoms of poisoning, this does not mean that the substance is safe. Toxins can accumulate over the years, undermining health. Even a small amount of them is poisonous if exposed for a long time.

Plastic entered our life only about 30 years ago. Now the first truly "plastic" generation is growing, while in order to draw conclusions about the effect of plastic on the body, one must observe at least five generations.

Once upon a time, milk was poured into glass bottles, herring and butter were wrapped in paper, and canned food was sold in cans. Today they have been replaced by plastic bags, PET bottles, plastic containers and disposable cups. Only not everyone knows how to properly handle popular plastic (or, as experts say, polymers) - which is fraught with health problems. Elena Yurkevich, a leading researcher at the SPC for Hygiene, named GO.TUT.BY eight mistakes in handling plastic containers and food packaging.

We believe that plastic is no different from glass, metal or paper packaging.

Most plastic packaging is not reusable for food. Its safety is correctly considered conditional: that is, the absence of harm is guaranteed as long as these containers are used strictly for their intended purpose, subject to certain storage conditions and no more than a specified period.

- Unlike the same glass, any polymers tend to "age", - explains the specialist. - That is, their integrity is broken over time, as a result of which various potentially hazardous substances that were added during production in order to give the material shape or strength, are able to migrate into food.

At home, the toxicologist recommends abandoning plastic dishes altogether. He considers its use justified only when there is no other container at hand: for example, on a hike or at a picnic. Concerning cutting boards, then if the hostess really wants to use plastic, the expert advises to change them more often.

We do not pay attention to the marking

For the production of food packaging and containers, about a dozen types of various polymers are used. What the bottle or wrapper is made of, you will be prompted by triangles in the form of arrows with a number inside or in Latin letters at the bottom.

The least safe are polystyrene (PS, or "six"), polyvinyl chloride (PVC, "three"), others (O, "seven"), polycarbonate (PC). These materials often contain dangerous "ingredients" - phthalates and bisphenol A. It has been proven in the West (and by its own research of the Hygiene Research Center of Hygiene) that, once in the human body, these substances can increase the level of estrogen, increasing the risk of developing cancer of the prostate, testicles, mammary glands , deteriorate sperm quality, reduce brain activity, provoke allergies, delayed brain development in children and cardiovascular diseases.

Therefore, when choosing products made of food-grade plastic, Elena Yurkevich recommends giving preference to those that are marked "BPA free" or "Does not contain bisphenol A", "BPA free". If there are no such inscriptions, it is better to refuse such products, especially if they are for a child or a pregnant woman. If this is not possible, give preference to packaging made of polypropylene (PP, or "five").

One of the safest for health polymeric materials - PET ("unit"). It is used to make bottles for soft drinks, mineral water, milk, some types of disposable tableware, boxes and blisters for confectionery products. The maximum shelf life of such a container is a year. Over time, its protective properties are lost, and toxic substances are released. Under external influences - damage, high temperature - the destructive process is accelerating.

We give polymer packaging a "second life"

Some thrifty housewives use PET bottles as reusable ones. They are washed with alkaline liquids, carefully rubbed with brushes and coarse sponges, and then compotes, water, milk are poured there. And in vain!

- Any scratches, chips, scuffs on the PET-container become a gateway for the transfer of toxic substances into the liquid, - says the toxicologist.

From this point of view, it is not worth re-packing food in plastic bags (denoted by "four" or "two"). "Washing" and the second life of the bags is permissible only if you plan to carry or store something inappropriate.

We heat food in a microwave in a plastic bag

If you carry your homemade meal with you and reheat it in the microwave, use only containers specially designed for this purpose - they are marked with the “waves with oven” icon. You can reheat food in a polypropylene container ("five"). Keep containers made of other types of plastic away from heat sources. When heated, it is possible to release substances hazardous to the body - formaldehyde, hexane and benzene.

- And more than once I had to witness how whites and pies in plastic bags are warmed up in cafeterias! - I draw the attention of a specialist.

- Poorly! It is necessary to conduct an educational program! - says Elena Yurkevich. - If this happened to you once, did not have time to stop the seller, nothing terrible will happen to the body. But if warming up in polyethylene becomes a habit and you, for example, do this every day, harmful substances will begin to accumulate, and the risk of their toxic effect will become real.

We store bread and vegetables in bags

A product wrapped in polyethylene is more likely to develop mold, and it also loses its taste faster, says Elena Yurkevich.

- Bread is allowed to be stored only in the packaging in which you bought it (it was tested before production, and there are special holes for air exchange). But the best option - after bringing the bread home, take it out of the packaging and put it in a wooden and metal breadbox, a bag made of thick paper.

We freeze food in non-intended polymers

For freezing, polystyrene packaging ("six") is best suited. It can be distinguished from other polymers by appearance - it resembles foam. A special container with a "snowflake" icon is also suitable. But the usual packages, in which products are actively packed in hypermarkets today, are not suitable for a freezer, according to a specialist. Do not be lazy to look in the economic departments for packages specially designed for this.

It is harmful to freeze polyethylene again: repeated temperature changes destroy the structure of the material. And in no case should you put berries, water, vegetables in PVC packaging ("troika") into the freezer - the toxic substance dioxin will start to be released into the food. Accumulating in adipose tissues, dioxin can ultimately lead to cancer, in particular, breast cancer.

We store fatty, hot, sour and alcoholic drinks in plastic for a long time

These are the so-called aggressive media: they activate the process of transfer of toxic components from polymer packaging to the product.

It is especially dangerous to drink alcohol, hot tea and coffee, soda from PVC cups ("three") and polystyrene ("six"). It happens that this rule ignored in some vending machines.

We leave products in vacuum polymer packaging after opening

A very common way of packaging fish, cheese and meat is in plastic packaging under vacuum. By removing air or filling the space with inert gas, the product stays fresh longer. The hygienist-toxicologist warns: immediately after opening the package, such products must be transferred to a metal, glass or porcelain container. Because as soon as oxygen enters there, the so-called spoilage microorganisms (molds, yeasts), which previously “dozed” in an oxygen-free environment, will begin to multiply. Leaving uneaten herring in an open package in the refrigerator can easily get food poisoning... And accusations that the product was “bad” would be unfair. Incorrect handling of the packaging is to blame.

- Of course, it is not easy for an average person to understand the variety of plastic packaging and containers, - sums up Elena Yurkevich. - But this is only at the beginning. It is important to form a healthy habit. And those who do not want to bother and delve into all the nuances should make the most of glass, porcelain and other safe dishes. And when purchasing a product in polymer packaging or containers, immediately throw it into the trash container for secondary use plastic.
