Adding edible gypsum powder to bean products does not meet food safety standards and should not be used. According to the Food Safety Law and the national standard "Bean Products", food additives must meet the national standards before they can be used, while edible gypsum powder is not among the additives allowed in the production of bean products. Therefore, it is illegal to add edible gypsum powder to bean products.

Edible gypsum powder is a white powder, which contains a lot of calcium and calcium sulfate. Some unscrupulous merchants often use it in the production of bean products to improve the hardness and quality of bean products. However, this will affect the taste and nutritional value of soy products and bring potential health risks. Long-term consumption of bean products containing edible gypsum powder may cause health problems such as kidney calculi.

When the food supervision department tests the bean products, it will test the additives added in the bean products. If illegal additives such as edible gypsum powder are found in bean products, the production enterprises will be punished and the related products will be recovered.

To sum up, it is illegal to add edible gypsum powder to bean products, and the food supervision department will find illegal additives through testing. Consumers are advised to choose the bean products of qualified regular production enterprises when purchasing to ensure food quality and safety.
