Beijing checks 10 supermarket cinema popcorn buckets mostly contain brighteners

On April 22nd, the “Investigation Report on the Quality of Popcorn Barrels in Five Cinemas and Five Supermarkets in Beijing” published by the International Food Packaging Association showed that five theaters including Jiahe, Huaxing, Singmei, Wanda, and Dongdu, as well as Carrefour and Tesco, were Among the five supermarkets including Wal-Mart, Jingkelong and Wumart, all investigated products contain fluorescent brighteners, and most of them have quality problems.

The investigation team found that although some of the popcorn buckets were printed with the QS logo and number, the popcorn buckets were observed under an ultraviolet analyzer and the barrels were bright and dazzling blue, which still contained fluorescent whitening agents. Secretary-General of International Food Packaging Association Dong Jinshi said: "If you touch the fluorescent agent in excess, there may be a potential cancer risk. When consumers buy popcorn in the theater, they should first check the popcorn bucket, if it is bright white, it is mostly unqualified. Product; if the barrel is naturally milky white, it is a qualified product."

In addition, microwave popcorn sold in supermarkets has certain problems. This type of product needs to be cooked in a microwave for 2-4 minutes. However, under the high temperature cooking of the microwave oven, the outsourcing paper did not ignite.

In this regard, Dong Jinshi said that most of the microwave popcorn bags are likely to be added Teflon coating, its main characteristics are high temperature, non-adhesion, anti-oxidation. However, since the temperature is close to 200 degrees Celsius during processing, the perfluorinated compound (Teflon) will begin to decompose. When the popcorn is released, the compound is completely decomposed. At this time, chemical substances (such as oil repellent) on the paper bag will be transferred to the food and absorbed by the body, leading to blood contamination.
