Desiccants are usually used in food packaging to prevent moisture and deterioration of food. Some food will affect the taste because of moisture, so food desiccants will be added to it.
Most food desiccants are silica gel desiccant and quicklime desiccant, but because quicklime desiccant will absorb moisture and release heat, it is easy to burn the skin. At present, few manufacturers use quicklime on the market. Silica gel desiccant has become the most common food desiccant in the market. It is harmless to human body. It is a physical desiccant, which will not be absorbed by human body even if it is accidentally eaten. The outer packaging of food desiccant is mostly Aihua paper, because this desiccant needs to be in direct contact with food, and Aihua paper is the best choice.
Therefore, it is found that silica gel desiccant is used in food. Even if the desiccant package is broken, as long as the food does not deteriorate and the taste is not affected, it can be eaten directly. But if you find that the food has gone bad or moldy, you can't eat it.
