How to avoid the harm of plasticizer to human health
Mooncakes with plasticizers have been reported to be uncomfortable, and the mooncake market has been affected as the Mid-Autumn festival approaches. Plasticizer is like a movie, it seems to be everywhere. Apart from other things, today we just talk about plasticizers. What harm does it do to human health? How can I get away from it? Plasticizer, which is commonly referred to as plasticizer, is a commonly used plastic additive. Adding this material to plastic processing can make it more flexible and easy to process. There are more than 100 kinds of plasticizers, and the most common ones are phthalates, such as dibutyl phthalate and diphenyl phthalate. The effect of plasticizer is to enhance the flexibility of the plastic, such as polyethylene, polypropylene, polyethylene terephthalate itself has good toughness, processing generally do not need to add plasticizer, or add in very small doses. But, polyvinyl chloride (PVC) and polyvinylidene chloride plastic material is hard, in order to make the product has a certain toughness, easy processing and forming, the plastic processing, the need to add a certain amount of plasticizer. The use of plasticizers is limited. The food containers and packaging materials used additives health standards, specific migration of DEHP, DBP (i.e., from food additives capacity, packaging materials and other products in the migration to the maximum limit of its contact with the food) or maximum residue were 1.5 mg/kg, 0.3 mg/kg. And it is only used in the contact of non-fatty food materials, not to be used in the contact of infant food materials. National food safety risk assessment center is introduced, the plasticizer in food mainly comes from two aspects: one is the contact of plastic food containers, pipes, packaging materials and seal materials migration into food; Second, the influence of plasticizer in the environment on food, such as the presence of plasticizers in soil and water, may enter the food chain to influence food. In addition, some food additives such as flavoring spices may contain plasticizers. The ministry of health, phthalic acid ester material can be used for food packaging material of plasticizer, not food raw material, nor is it a food additive, is strictly prohibited in the food, food additives, artificial added. Is there any plasticizer in soy sauce? Look at the production of soy sauce first. According to the technical staff of li jinji, a century-old name, the traditional way of brewing is to ferment it with soybean, flour and salt, without adding any spices or essence. Wash the beans first, then steam them with high pressure steam. Then, the steamed soybeans are mixed with flour and pulverized flour and mixed with salt water. The conveying tube and the soy sauce conveying are made of stainless steel, anti-corrosion. The fermentation cylinder is made of glass fiber. The process can be said to be nothing to do with plasticizers, and look at the packaging. At the moment, most soy sauce is bottled in glass, and some large ones are plastic bottles. The plastic is made of PET material. The most common plasticizers are esters, which are the most soluble in fatty substances. Second, soluble in alcohols such as liquor; Esters are soluble in water-based substances such as various beverages and soy sauce. So "soy sauce", or plastic bottles, is not that dangerous. PET plastic bottles are best discarded after a single use, and don't use them over and over again. Some studies have found that the PET material, which has been used for 10 months, may release DEHP, the plasticizer. Also avoid putting bottles in direct sunlight and warmer temperatures, and not hot or hot drinks. Some consumers use soda bottles for old wine, soy sauce, vinegar and other flavorings are not desirable. Some toxic plasticizers, such as DEHP and DBP, can be harmful to human health. Peking union medical college hospital professor endocrinologist xue-yan wu said, according to the us has formed the modern way of life, completely avoid plasticizer is almost impossible, but it is not necessary to excessive tension, because in normal life come into contact with the plasticizer will not harm the human body. Whether plasticizer can be harmful to human body, depends on quantity. The national food safety risk assessment center says the effect of plasticizers on people's health depends on how much they consume and how long they take in. Animal studies have shown that in the world, as well as the long-term high-dose consumption "plasticizer", may interfere with the endocrine system, and reproductive toxicity, such as damage to male reproductive ability, to promote female precocious puberty. From to ensure human health, according to the research of the international authoritative health appraisal institutions, adult lifetime DEHP not more than 3 mg per day, intake of DBP is not more than 0.6 mg, won't cause health hazards. Understanding plasticizers, we don't need to talk about "plastic" color change, it is not necessary to "avoid" all plastic products. The experts said that whether plasticizer can be harmful to human body depends on the amount of "quantity". In addition to the previous plastic bottles, don't use them over and over again, there are several references: first, you should use PVC products less. If the plastic is labeled with PVC, it contains plasticizer, which needs special attention when buying and using. Especially when choosing children's products, too soft, too small plastic products to buy less. When buying plastic film, choose polyethylene preservation film, do not buy unmarked. The food that carries the plastic film must not put in the microwave oven heating, especially the meat, the plasticizer once the contact grease, will release poisonous substance. Also, don't put any plastic containers in the microwave until they are labeled for special purpose. Because plastic products heated up, or exposed to oil and other substances, it will increase plasticizer migration in plastic. The second recruit: multi-purpose porcelain tableware. Eat less disposable plastic packaging of food, when serving food at home, try to choose porcelain tableware. The temperature of a plastic bottle made of PET is 70 degrees, so avoid using plastic containers or plastic bags for hot water, hot soup, hot soy milk and so on. Use less plastic bags and disposable containers when you're packing meals. It is also unsafe for parents to keep plastic bottles in hot water for easy feeding. Glass bottles are recommended. Step 3: eat less animal fat. Many toxic chemicals travel through the food chain in the form of fat, eating less animal fat, and significantly reducing the chance of the human body being disturbed by environmental hormones. The fourth recruit: stick to the principle of "two or three more," namely, less processing, less food additives, more natural, more fruits and vegetables, as well as preservatives, coloring and spices.
