The 6th cup lid "detoxification" can cause cancer?
The hot drink cup cover marked with the number 6 on the net will “detoxifyâ€. The Legal Evening News reporter interviewed the experts in the morning, saying that the number "6" means that the material of the cup cover is polystyrene, and the toxic substances will be released when the temperature exceeds 90 °C, but the hot drink cups produced by the regular manufacturers are non-toxic. . Most of the hot drinks commonly found on the market are below 90 °C. Even if the temperature is too high, it is harmful to the human body to drink 640 cups of hot drinks a day. Visit "No. 6 cup cover" is carcinogenic Common use in the market “A lot of hot drinks have a triangle on the lid of the hot drink. The 6th plastic material is polystyrene. It will be 'detoxified' at high temperatures. It is best to drink hot drinks without a lid.†A message about the lid Aroused the attention of netizens. In the market, the "No. 6 cup cover" is indeed widely used. The Legal Evening News reporter visited three fast food restaurants, four existing beverage shops and two cafes near Chongwenmen. Among them, a cup used in a coffee shop has a number "2", and the rest of the stores use the number "6". The colors are not uniform, black and white. The figures on the lid represent what it means, and many salespeople don't know. "It should be the grade of plastic. I don't know what plastic it is," said the clerk at the CoCo beverage store. However, he repeatedly stressed that no matter what material, it can be safe to use. Interpretation 1 Production is not harmful What does the number "6" mean? Is there any poison in the end? Dong Jinshi, secretary-general of the International Food Packaging Association, told reporters that “6†represents the material used to make such a lid is polystyrene (PS). Under normal circumstances, production quality qualified polystyrene products are non-toxic. Styrene is only released if it is used improperly. Interpretation 2 ordinary hot drinks are difficult to reach temperatures above 90 °C Dong Jinshi said that the use of the No. 6 cup cover will release styrene, and one of them will be hot drinks with a temperature above 90 °C. So, what is the temperature of the hot drinks we usually buy? The reporter bought hot drinks at seven shops including McDonald's, KFC, Happy Lemon, CoCo, and Street Street, including milk tea, fruity hot drinks, coffee and black tea. Test the temperature of the beverage with a thermometer immediately after getting it. Among them, the highest temperature of black tea is 83 ° C, while the temperature of fruity hot drink is the lowest, only 45 ° C. Among the 8 drinks evaluated by the reporter, there was no hot drink temperature reaching 90 °C. Zhou Hongjie, a physics teacher at the middle school level, said that during the production process, many need to add coffee powder or milk powder will accelerate the loss of water temperature. Together with the agitation, the process of temperature loss is further accelerated invisibly. Most of the beverage stores use insulated tubs or direct drinking water heating systems. If it is not just boiled, the hot water used to make the beverage is difficult to reach a high temperature of 100 °C. “If the cup is filled with 100°C boiling water, even if there is insulation layer, it is difficult to get it in the hand. The staff of the beverage store will have nothing to do when making the drink, which proves that the water temperature is not as high as 100°C.†Teacher Zhou Say. Interpretation 3 even if "detoxification" drink 640 cups a day is harmful “Even if the temperature of the hot drink exceeds 90°C, the quality of the lid is still within the safe range of the styrene,†said Yan Guangfeng, a master of nutrition and food safety at China Agricultural University. Shuguang Feng said that the national standard stipulates that the upper limit of the monomer content of styrene in polystyrene is 0.5%. Assuming that the styrene content of a hot beverage lid (typically 3 grams) reaches an upper limit, the amount of styrene precipitation cap that may enter the beverage is about 3.75 micrograms in an environment above 90 °C. JECFA (Joint Expert Committee on Food Additives under the Food and Agriculture Organization of the United Nations and the World Health Organization) has a tentative maximum allowable daily intake of 0.04 mg/kg of styrene. The reporter calculated that a 640 cups of hot drinks a day would be harmful to the body.
