Experts suggest not to use plastic drinking cups to hold milk beverages 2017-01-24 15:37 According to reports, the purchase of this sample was purchased randomly from commercial physical stores and online e-commerce platforms as ordinary consumers, a total of 50 Samples, 37 brands. Among them, there are 28 samples from supermarkets and shopping malls, 11 samples from wholesale markets, and 11 samples from online stores. Product prices cover high, middle and low grades. The test results showed that of the 50 test samples, 3 samples failed to meet the national standards, mainly because the phenol-distilled water and acrylonitrile monomer exceeded the standard. Is the cup poisonous? Experts suggest not to use plastic drinking cups for milk beverages. According to Mao Kai, an engineer at the Hardware Packaging Product Testing Center of Jiangsu Product Quality Supervision and Inspection Institute, the raw materials for the production of these children's plastic water cups sampled are mainly polycarbonate (referred to as PC) and acrylonitrile-styrene copolymer (referred to as AS). When polycarbonate is heated to too high a temperature, used for a long time or encounters acidic substances, it is easy to precipitate free phenol, which is a harmful substance. When the free phenol is absorbed into the human body to a certain amount, it may damage the liver and kidney cells and cause chronic poisoning. The degree of harm is no less than that of phenol and formaldehyde. Among the 23 samples of PC material children's plastic drinking cups purchased this time, only the Xintong 280g children's cup produced by Taizhou Huangyan Xintong Plastic Factory does not meet the standard and is harmful to children's health. Engineer Mao said that the raw materials for the children's water cups sampled this time are also acrylonitrile-styrene copolymer materials (AS), which is a plastic raw material with high transparency, oil resistance and chemical resistance. It is used in food utensils. Widely used, such as food tableware, plastic water cups, etc. Acrylonitrile that may remain in AS plastic is a chemical substance that has serious health hazards. Once the human body ingests excessively, light people may be dizzy and nauseous, and severe cases may directly cause anesthesia of the respiratory center and cause paroxysmal stiffness of limbs. Convulsions, coma. my country's relevant mandatory national standards stipulate that the residual amount of acrylonitrile monomer in AS products for food contact shall not exceed 50mg/kg. A total of 2 children's plastic drinking cups made of AS material were purchased this time. The test results showed that the two samples did not meet the national standards. Among them, the Zhenxing bear-shaped straw cup produced by Guangzhou Nansha District Zhenxing Plastic Co., Ltd., the actual measurement of acrylonitrile monomer 56mg/kg; THOMASu0026FRIENDS dream transparent big kettle produced by Wanghong Mould Plastic Products Factory, measured 59mg/kg of acrylonitrile monomer. It is not recommended to use plastic drinking cups to hold beverages and milk. It is understood that after obtaining the test report, the Provincial Consumers Association contacted the distributor and the e-commerce platform as soon as possible, and entrusted the distributor and the e-commerce platform to contact the manufacturer for this test. Make a written explanation of the results and propose corrective measures. However, as of the date of publication, only 2 of the 3 companies that did not meet the standards came to confirm. Among the companies that came to confirm, Guangzhou Nansha District Zhenxing Plastic Co., Ltd. (Zhenxing Xiaoxiong Straw Cup), Taizhou Huangyan Xintong Plastics The factory (Xintong 280g children's cup) removed the products with the same production date or batch (goods) number involved in the comparison test. The overall quality of the children’s plastic drinking cups sampled this time is relatively high, but individual products still have problems. How should consumers choose when buying these products? Engineer Mao Kai gave 5 suggestions: (1) When buying children’s plastic drinking cups, you should Pay attention to whether the information in the product label is complete, such as: manufacturer, production license number, implementation standard, material, etc. Among them, the material should list in detail the materials of all parts that may come into contact with food, such as: cup lid, cup body, straw, etc. (2) It is recommended that consumers go to regular stores and try to buy products in large supermarket chains or special maternal and child supplies stores. The products sold by these units generally have a fixed purchase channel, and the quality of the purchased products is more stringent, and the product quality is relatively reliable. (3) Among the common children's plastic drinking cups on the market, polypropylene (PP) is a relatively safe material (the bottom of the bottle is marked with number 5). Except for polypropylene (PP), children's plastic drinking cups of other materials are not recommended. The microwave oven is heated and disinfected to avoid the release of substances harmful to human health. (4) It was found from the test results that the samples that did not meet the standard belong to the low-to-medium price range. When purchasing children's water cup products, more attention should be paid to the safety performance of the product, not just the price factor. (5) Except for water, it is not recommended to use plastic drinking cups for long-term storage of carbonated drinks, milk and other foods.
