Can food moisture prevention use mineral desiccants? At Tengye Desiccant, we first need to determine what type of desiccant is used inside the food. Generally, moisture-proof desiccants used in food packaging include silica gel desiccants and quicklime desiccants. Therefore, mineral desiccants are not recommended for moisture prevention in food packaging. Mineral desiccants are usually used in hollow glass, instruments, and electronic products fields.

Silica gel desiccant is commonly used for moisture prevention in food products. At Tengye, we understand that silica gel is a physical adsorption desiccant, not a chemical reaction moisture absorption desiccant. Moreover, silica is an FDA-approved raw material that can come into direct contact with food and drugs. Compared to other desiccants, silica gel is particularly safe for use in food moisture prevention. Beyond the aforementioned factors, silica gel desiccant also boasts strong moisture absorption and adsorption capabilities; it will not dissolve when fully immersed in water. It is non-toxic, odorless, and non-corrosive, making it safe even if accidentally ingested.
