There are not a few consumers who fall into the trap of "gilded food" because of curiosity or pursuit of extravagance. Seeing the business opportunities behind the food containing gold and silver foil powder, some merchants not only sell such goods, but also use various words to package such goods and publicize the "healthy" selling point that some "gold-plated food" advertised during the sale, which is not true. The gold and silver foil powder will not be absorbed by the body, but will be discharged out of the body as it is. It has no nutritional value to the human body. It is difficult to regulate the "gold-plated food". The core reason is that the specifications are not clear and the technical supervision methods are not up to date. As for the industry in which gold and silver foil powder is used, the policies and legal rules are not clear enough. To a certain extent, it gives the merchants the space to use gold and silver foil powder arbitrarily. The exquisite cake is inlaid with a circle of gold foil, which complements the gold and silver ball decorations on the surface of the cake; The round and smooth chocolate is scattered with gold foil powder, like the stars in the night sky; The small and fresh sea urchin stab is decorated with several pieces of broken gold, which makes people's fingers move... The food added with gold and silver foil powder is called "gold-plated food". However, no matter how luxurious the packaging is, the fact that gold and silver foil powder is an illegal additive can not be covered up. Recently, the State Administration of market supervision, the Ministry of agriculture and rural areas, the National Health Commission and the General Administration of Customs jointly formulated the provisions on investigating and dealing with illegal acts of producing and selling gold and silver foil powder food (hereinafter referred to as the provisions), which clearly stipulates that the gold and silver foil powder is not included in the national standard for food safety and the standard for the use of food additives (gb2760-2014). It is not a food additive, is not a food raw material, and cannot be used in food production and management. However, the reporter of the rule of law Daily recently found that although the shops selling gold and silver foil powder can not be found in the search keywords of online shopping platforms and takeout platforms, after searching with the keywords of "edible gold foil" and "edible silver powder", it can still be seen that many stores are selling relevant materials. In addition, many consumers still favor this kind of "gilded food" and share their pictures and videos of "eating gold" on social platforms. Why should "gilded food" be prohibited? Why is it that despite repeated prohibitions? How should we guard against it? With these questions in mind, the reporter conducted an investigation and interview. Gold and silver foil powder is not nutritious and extravagant. It should be prohibited that Mr. Jia, a resident of Chaoyang in Beijing, still keeps a bottle of gold foil wine bought a few years ago in his home. "Nobody drank it. It's a pity to throw it away. It's just under the bed. It's all dusty." In the summer of 2018, when Mr. Jia was shopping in a tobacco and wine supermarket, he saw a particularly conspicuous bottle of wine on the shelf. The bottle body was transparent, and the golden light at the bottom of the bottle could be clearly seen. Mr. Jia consulted the shopkeeper about the wine. The shopkeeper immediately took the wine off the shelf and shook it twice. The gold foil in the wine floated up. Under the light, the whole bottle of wine looked "sparkling". According to the owner, this is the gold foil wine purchased through internal channels. The edible gold foil powder added to the mellow Baijiu has not only nutritional value but also high collection value. He praised that "gold foil powder can only be eaten by ancient emperors
