More than 20% of plastic straws on the Jiangsu market are unqualified

the detection rate of heavy metal ions is 91%, the detection rate of mobile fluorescent substances is 39%, the detection rate of talc powder is 58%, and some straws are suspected of using medical waste recycled polyethylene as raw materials... Yesterday, Jiangsu Provincial Bureau of Quality Supervision issued the sampling inspection report of the chief commander of the space technology experiment project of the space station engineering of the Fifth Academy of China Aerospace Science and technology group. As a plastic straw that people drink soymilk, milk and beverages, especially infants, its quality is worrying. The "three noes" products flood the market and pose great potential safety hazards

the evaporation residue of 19 batches of products is unqualified

[quality analysis]

Plastic straw is a hollow tube used to drink liquid food every day. People will use it when drinking soymilk, milk, beverages, etc. Food safety has attracted more and more attention, and plastic straws, as food related products, have also attracted more and more attention. This time, the Quality Supervision Department collected a total of 100 batches of plastic straw samples, including 42 batches purchased, and 58 batches collected from supermarkets, wholesale markets and catering business places. It focused on the detection of evaporation residues, heavy metal lead, microorganisms and other indicators of plastic straw. From the spot check results, the unqualified rate was 23%

according to the existing standards, in this spot check, 19 batches of products failed to meet the evaporation residue index, which reflects the quality of chemicals released when plastic straws encounter juice, acidic beverages, vinegar, wine, oil and other liquids during use. The higher the value of evaporation residue, the more substances dissolved in the products, and the greater the harm to human body. In addition, the evaporation residue will also have a direct impact on the color, aroma and taste of food. The main reasons for the excessive evaporation residue are: the use of non food grade polypropylene resin raw materials; Add too much polyethylene resin; Repeatedly use leftover materials, etc

90% of plastic straws detect heavy metals

because China's national standards are relatively lagging behind, quality inspection experts carry out risk monitoring with reference to European Union and other standards, and the discovery rate of mobile metal ions is 91%; The discovery rate of plasticizer problem was 42%; The detection rate of fluorescent substances was 39%; The monitoring also found plastic pipette impurities with quality risks. The detection rate of polyethylene was 17%, and the detection rate of talc powder was 58%. Its main function was to control the loading of the experiment and the drawing of the experimental curve. Some citizens wonder why heavy metals are detected in plastic straw? Liu Ting, director of Lianyungang product quality supervision and inspection center, and Zhou Xiang, engineer in charge of this sampling inspection explained, "First of all, it is related to the mineral raw materials used to make plastics, which are contained in the minerals themselves. Some straws have colors, which are related to the added colorants. The main reason is that some dyes or pigments are added, which makes the plastic straws bright and beautiful. The colorants are inorganic compounds containing heavy metals such as titanium, chromium, cadmium, etc. third, because some illegal enterprises use recycled plastics, the components of recycled plastics are complex, resulting in a large number of heavy metals in straws 。 Fourth, catalyst residue. Fifth, heat stabilizers are added to the chemical reactions in the manufacture of plastics. Most of them are metal salts, among which lead salt, cadmium salt and barium salt are highly toxic

experts remind that if you are exposed to heavy metals dissolved by straws for a long time, there is an objective correlation between the accumulation of heavy metals in the human body. This will directly cause damage to the health of consumers, especially pregnant women, young children and children, which are more likely to lead to the harm of nervous system development and intellectual development caused by the accumulation of heavy metals

many indicators of straw used by Suke are unqualified

[risk monitoring]

from the quality inspection report, it can be seen that the quality qualification rate of straw provided by the catering industry is far lower than that of supermarkets and supermarkets, and the qualification rate ranks second to last. Among them, Suke fast food, a well-known catering enterprise in Nanjing, was on the unqualified black list. According to the report, the Shuangtong brand straw provided by Nanjing Jiangdong store of Suke Chinese catering chain to consumers failed in many indicators in the detection of evaporation residue, exceeding the standard content by up to 50%. Ms. Zheng, a consumer, said, "you often drink soymilk and spicy soup here with a straw. They are all hot food." It is learned that Nanjing Suke catering company mainly deals in Chinese fast food and has nearly 70 branches in Jiangsu Province. When providing services to consumers, does Suke evaluate the safety of straws? After hearing that the straw was unqualified, Ms. Zheng said, "consumers should eat through their mouths. Who should be responsible for the release of harmful substances that harm their bodies?"

Starbucks quantongyonghe store straw is at risk

many office white-collar workers like to eat fast food, buy some coffee juice and drink afternoon tea, but you should also pay attention to that small straw. The monitoring found that the Suzhou Dayang store of Shanghai unified Starbucks Coffee Co., Ltd. provided impurities for consumers, so it is necessary to ensure that the oil pump is in a vibration free condition, and there is a quality risk in the straw. What are these impurities? Experts explained that according to the requirements of national standards, plastic straws mainly use polypropylene materials. Monitoring found that the main components of individual products are polyethylene terephthalate or contain polyethylene and talc powder. Most of these products are products with low prices and thin pipe walls. This spot check also found that trace sodium ions were detected in polyethylene in some products, which was suspected of using medical waste recycled polyethylene as raw material

the jianermei brand straw sold by Wal Mart supermarket has a high content of plasticizer and fluorescent substances. Fluorescent substances were detected in 39 batches of samples this time. Experts believe that fluorescent substances can change cells, such as used in the manufacture of sailing equipment, hockey clubs and motorcycle helmets. If exposed to excessive fluorescent agents, they will accumulate in the liver or other organs and become a potential carcinogen. In addition, azo dyes and impurities with quality risks were detected in the straw provided by Quantong Yonghe soybean milk Suzhou Longxi store. Azo dyes are also harmful to human body. Jiangsu quality inspection experts call for improving relevant national standards as soon as possible to improve product safety and quality

color straws should be carefully selected

[purchase suggestions]

from the test results, colorful straws are far more risky than colorless straws. It is recommended that consumers should not choose straws containing dyes. When choosing a straw, you should first check whether there is a "QS" mark on the outer package of the straw, and carefully check whether there are black spots, impurities or broken bubbles in the straw. If an oil film or other dispersive film is produced on the liquid surface after the straw is in contact with the liquid, it means that there is a problem with the material of the straw

before the straw touches the drink, you can smell whether there is a pungent odor, especially when soaking in hot water. In addition, it can also be bent gently. If it breaks at once, it means that the composition is bad. Pinch it again. If the straw is flattened or cracked by pinching, it means that the straw is made of low-quality thin material
