Hello, don't use defoamer indiscriminately. Defoamers sold in the market are all processed tofu, and it is illegal to use them on vermicelli! You can add some cooking oil. At present, alum is not allowed to be used in the production and processing of starch products such as vermicelli, vermicelli, thin face, vermicelli and bean jelly. And phosphates, preservatives and the like. Can not be used beyond the scope, can not add borax and other non-edible substances. Otherwise, it is the crime of abusing food additives beyond the scope, which violates Article 46 of the Food Safety Law! ? In the next step, starch products production and processing plants should abandon alum thinking and not use food additives such as phosphate beyond the scope. Under the legal premise, we should change the production process and use food additives with QS certificate to produce real alum-free products!
