  • Detail

On June 7, the station of the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China (AQSIQ) made it easier for users to quickly carry out experimental operations and data viewing, and updated the list of problematic enterprises contaminated by plasticizers and their related products published in Taiwan, of which 279 were problematic enterprises and 948 related products. The General Administration of quality supervision, inspection and Quarantine of the people's Republic of China (AQSIQ) stressed that the relevant products of problematic enterprises shall not be imported. In recent days, Taiwan's plasticizer contaminated food incident has become a matter of great concern. For a time, people talk about "agents" turning pale. Today, when food safety has attracted great attention, the turmoil in Taiwan has made people know another chemical term - plasticizer

what kind of substance is plasticizer in 27 colleges and universities such as Jilin University and Northeast Normal University, and 357 R & D institutions such as Applied Chemistry Institute and Changchun Institute of biological products? What plasticizers are there around us? How harmful is it to human body? Through investigation, we can restore a real plasticizer for you and explore the secrets behind it

[answer to hot words]

what is plasticizer

as a kind of industrial additive, there are dozens of types of plasticizers. The mainstream variety DEHP appeared in the plasticizer contaminated food this time (phthalate ester plasticizers such as DINP, DBP, DMP and DEP were successively detected later). Its chemical name is "phthalate ester". It is a toxic and highly carcinogenic plastic softener for the chemical industry. It is a colorless and tasteless liquid, After addition, the particle molecules of the product can be more evenly distributed, so it can increase the ductility, elasticity and softness. It is often used as raw materials for sofas, car seats, rubber tubes, cosmetics and toys, and belongs to industrial additives

the harm of plasticizer

the plasticizer DEHP is mostly used in plastic materials. It is an environmental hormone, which will harm men's reproductive ability and promote women's precocious puberty. If it accumulates a high dose in the body for a long time, it may cause gender disorder in children, including shorter genitals and less obvious sexual characteristics. At the same time, plasticizers can also produce other side effects. If a large number of plasticizers are taken for a long time, they will cause heart, liver and kidney toxicity, and increase the risk of cardiovascular disease

however, experts say that the vast majority of DEHP and its metabolites will be excreted with urine or feces within 24 to 48 hours, which has little impact on health. However, 85% of DINP was excreted from feces within 72 hours, mainly in the first 24 hours. In animal experiments, to cause liver cancer and other serious diseases, we need to drink dozens of bottles of sports drinks containing plasticizer DEHP every day for half a year, so we don't have to worry too much about the harm of their intake

[experts' statement]

people don't need to talk about "agent" color change

plasticizer, cloud forming agent, DEHP... These words, which have been very popular in the recent material experiment instrument Expo in major stations and micro high reliability, have had a negative impact on people's hearts. Some people began to refuse Taiwan brand beverages sold on the market, and even panic about additives. What are these unfamiliar chemical terms? What is the relationship and function between them

plasticizers must not be added to food

as one of the key words in the "toxic beverage" incident in Taiwan, plasticizers are called plasticizers in the mainland. They are a class of chemicals that have a similar solvation effect on plastic, rubber, adhesives and other polymer materials. Their function is to give polymer materials products appropriate softening function. It can be added to plastic polymers to increase the plasticity of plastics. There are more than 100 kinds. At present, the plasticizer is not included in the physical and chemical indicators of edible oil inspection in the national standard, and the content of plasticizer is not specified, but it is clearly stipulated that DEHP is not allowed to be used in the packaging materials of fat food and infant food. According to relevant research and survey results in China, DEHP intake through diet is common. The daily intake of DEHP by Chinese people from food is about 1.029 mg

Professor Zhang of Applied Chemistry College of Shenyang University of chemical technology has been engaged in food research for a long time. According to him, "plasticizer is a pure industrial raw material, which is widely used in domestic plastic products. After adding it, the flexibility of plastic products can be enhanced. However, adding it to beverages or other foods as an additive is absolutely not allowed and illegal." In the United States, Germany and other countries, plasticizers are also banned from being added to food related plastic products, and they are not likely to be added to food as additives

using plasticizers is only "cheap"

"in fact, 'cloud forming agent' and 'plasticizer' are not the same substance. The problem exposed in Taiwan's' toxic beverage 'incident is that some illegal production enterprises use toxic plasticizers instead of permitted cloud forming agents." Professor Zhang said

according to the introduction, clouding agent, also known as turbidity agent, emulsifying agent and turbidity increasing agent, is a commonly used emulsifying stabilizer, which is generally used in the processing of fruit juice and other beverages. After being added, it can help release the aroma of fruit juice beverages, enhance the lubricity and thickness of the taste of fruit juice beverages, and significantly improve the quality of fruit juice beverages. "The general raw materials of cloud forming agent are gum Arabic, emulsifier and palm oil, among which the most important raw materials are palm oil and other vegetable oils. However, it should be noted that the price of palm oil is very high. In order to reduce the cost, these illegal businesses use toxic plasticizers to replace cloud forming agent, because the price of plasticizer is only about one fifth of that of palm oil. In this way, the use cost of additives alone has been greatly reduced, and the effect is almost zero What difference can make the product taste better. "

it is common to add emulsifiers to food.

with people's attention to food safety and mistrust of problem food, a large number of food additives in life are well known

in Taiwan, it was found that toxic plasticizers were added to beverages, jam and other foods to replace cloud forming agents, which made people more worried about food additives. Some citizens even said that "food produced in factories is unsafe", "as long as there are food additives, you can't eat"...

but the answers given by food experts are different, "Most of the foods we encounter in our life contain food additives, because they are a necessary means to extend the shelf life and enrich the taste of food. The types and dosage of food additives are strictly controlled and allowed by the state, so there is no need to doubt them."

Mr. Gao, who has operated food additives in Shenyang Naner wholesale market for nearly 10 years, has his own judgment on the "toxic additives" incident in Taiwan. Mr. Gao said: "I have sold more than 100 kinds of food additives at the most time here. We usually drink beverages, milk, ice cream and biscuits, jelly and puffed food that children like. There are at least two kinds of food additives, among which emulsifiers are the most common." "The 'cloud forming agent' in Taiwan is the emulsifier we sell. It is mainly divided into natural products and synthetic products. Artificial emulsifiers with prices ranging from tens of yuan to more than 100 yuan are the most popular. Some food factories that produce beverages and ice cream will come here to pick up goods. Adding them to the products will make the flavor of beverages strong and the texture of ice cream sticky." Mr. Gao said, "we don't have to worry about the safety of emulsifiers. There will be no problem with the products produced by regular manufacturers."

[how to deal with]

restrictions on plasticizers in various countries

United States: according to the research results of the National Cancer Institute, the US Environmental Protection Administration has stopped the production of six phthalate esters including DEHP. Plasticizers are only used in food packaging with high water content. Meat packaging must be replaced by other non-toxic plasticizers. The U.S. Food and drug administration believes that it is safe for adults weighing 60 kg to consume 2.4 mg or less of DEHP per person per day for life

Switzerland: the Swiss government has decided to ban the use of plasticizers in children's toys

Germany: Germany prohibits the addition of plasticizer in all plastic products related to human health and food

Japan: plasticizers are forbidden to be added to medical device related products in Japan and are only used in industrial plastic products

"plasticizer" incident expanded from beginning to end

on May 24, relevant parties in Taiwan reported to the AQSIQ that it was found that the food additive "clouding agent" manufactured and sold by Taiwan "Yushen flavor Co., Ltd." contained the chemical component phthalic acid (2-ethylhexyl) ester (DEHP), which has been used in the production and processing of some beverages and other products. The General Administration of quality supervision, inspection and Quarantine of the people's Republic of China (AQSIQ) immediately asked the entry-exit inspection and quarantine institutions of various regions to strengthen the inspection and supervision of relevant additives, beverages and other products from Taiwan, so as to prevent problematic products from entering the mainland

On May 31, AQSIQ issued the announcement on Further Strengthening the inspection and supervision of imported food, food additives and related products from Taiwan, and also issued the notice on Further Strengthening the inspection and supervision of food phthalates to the inspection and quarantine bureaus directly under the AQSIQ and local quality and technical supervision bureaus

Since June 1, AQSIQ has suspended the import of sports drinks, fruit juice, tea drinks, jam fruit pulp, gum ingot powder or food additives produced by manufacturers of problematic products notified by Taiwan. The above products imported from Taiwan must be submitted for inspection with the inspection certificate issued by a qualified laboratory in Taiwan that does not contain phthalates. If the inspection certificate cannot be provided, the import shall be suspended

On June 5, the General Administration of quality supervision, inspection and Quarantine of the people's Republic of China (AQSIQ) again updated the list of problematic enterprises contaminated by plasticizers and their related products published in Taiwan. The number of problematic enterprises increased to 276 and the number of related products increased to 924
