The amount of plasticizer dissolved in the hottest

  • Detail

The amount of plasticizer "dissolved" in plastic packaged beverages is small

yesterday, the Shanghai 2011 food safety publicity week was launched at the South Wharf community cultural center in Pudong New Area. At the launching ceremony, a group of experts joined the food safety volunteer team

at the special lecture on "the merits and demerits of food additives", Li Shuguang, a member of the Municipal Food Safety Advisory Committee and a professor of Fudan University, specially mentioned a scientific research on the migration of plasticizers in plastic packaging of beverages in March this year. The contents of DBP (dibutyl phthalate) and DEHP (diethylhexyl phthalate) in beverages are far below the internationally permitted migration standards

trace plasticizers can be found in the small age. Li Shuguang has studied plasticizers for 16 years. His research team conducted a scientific research on the migration of plasticizers in plastic packaging of beverages in March this year. The research objects are 49 kinds of beverages, including 20 kinds of tea beverages, 21 kinds of fruit juice beverages, and 8 kinds of coffee milk beverages. The study found that the detection rate of DBP was 98%, and the detection rate of DEHP was 100%. The total DBP content in the beverage is 0.037mg/l (the national allowable migration standard is 0.3mg/l); The total DEHP content is 0.078mg/l (the national allowable migration standard is 1.5mg/l)

"plasticizers are encountered every day in life, which cannot be avoided." Li Shuguang explained that putting hot steamed stuffed buns, steamed buns, corn cobs and snacks into plastic bags, rubbing perfume, applying nail polish and hair styling water may "meet" with plasticizers, and even a very small amount of plasticizers exist in the air and water

Li Shuguang said that there are about 20 kinds of plasticizers, of which the most commonly used are DEHP, DVP and DOP. DEHP was found in Taiwan this time, accounting for 86% of the global consumption of plastic plasticizer. "In fact, this plasticizer with complex chemical names is a phthalate chemical component contained in plastic bags and plastic products. Adding this chemical component can increase the plasticity and flexibility of plastics and improve the strength of plastic products."

Li Shuguang pointed out that the plasticizer incident in Taiwan was artificially added to food additives directly, with high dose and high toxicity. What he studied is mainly the migration amount of plasticizer in plastic packaging. At present, the maximum experimental load of the sample breaking amount should be between 20% and 90% of the range of the experimental machine. The amount of plasticizer migrated from plastic packaging is very small. Because the human body has metabolic function, 1151 type gear pump extruder can be designed and developed in hours, which is discharged out of the body with urine or feces. Such a small amount is not enough to bring harm

citizens should consciously control the abuse of plastic bags and containers

experts suggest that the government should introduce relevant administrative measures to prohibit the free use of plastic bags, control the abuse of plastic containers, and prevent plasticizer pollution from the source. Citizens should also consciously stop and prevent the littering of plastic bags

in addition, China's food industry should also vigorously advocate reducing the use of plastic packaging containers, especially avoiding the direct contact between plastic products and various foods in 2013, so as to prevent the pollution of plasticizers to food. At the same time, the state should also increase investment in scientific research, carry out research on the toxicity of plasticizers, and conduct prospective epidemiological investigations related to human health, analyze and understand the toxicity of plasticizers from the cellular, molecular, genetic and other levels, develop and develop higher quality and safer alternative products in the polymer field, and study relevant intervention and prevention measures

as for food additives, Li Shuguang believes that food additives are everywhere in daily life, and there is no need for citizens to be afraid of food additives, let alone panic

however, food additives must not be added indiscriminately. The key to controlling malignant food safety emergencies lies in the source

more than 100 experts served as food safety volunteers

at the launching ceremony of Shanghai "food safety publicity week" yesterday, a group of members of the "Municipal Association of veteran scientists" with relevant professional backgrounds, professional skills and knowledge, such as Professor Ning Xibin of the school of food science of Shanghai Ocean University, became food safety volunteers. The Municipal Food and drug administration revealed that the "expert team" in Shanghai has reached more than 100 people, and they will enter communities, schools and enterprises to publicize scientific knowledge of food safety

this publicity week is a centralized publicity activity with the theme of "everyone cares about food safety and everyone enjoys a healthy life", which is carried out synchronously throughout the country according to the unified deployment of the State Council. During the food safety publicity week from June 13 to June 20, the city will carry out a series of publicity and popular science activities for the public. At the same time, the city will print and distribute "food safety knowledge series publicity" leaflets to the public, publish relevant trends of food safety supervision through the media, and publicize and popularize food safety information and knowledge
