What is the effect of food desiccants on food moisture prevention?

Food desiccants usually use silicone desiccants. If food packaging needs to be in contact with food for moisture prevention, the safety requirements for desiccants will be relatively strict. Silicone desiccants are an environmentally friendly desiccant specifically developed for moisture prevention of food, pharmaceutical products, and other products. Silicone desiccant is insoluble in water and any solvent, non-toxic, odorless, chemically stable, and does not react with any substance except strong alkalis and acids. The product quality fully meets environmental requirements such as ROHS and REACH, and meets the Chinese chemical standard HG/T2765-2005. It does not contain harmful substances such as DMF (dimethyl fumarate). At the same time, silicone is also certified by the US FDA as a desiccant that can be used in direct contact with drugs and food.

Silicone desiccant can effectively prevent food from getting damp. During the production and storage process of food, there will be air in the packaging bags, and there will be moisture and moisture in the air. The moisture absorption rate of silicone desiccant is about 30%, which can effectively absorb moisture in the air of food packaging, keep the food packaging environment dry, and prevent food from getting damp, moldy, and spoiled.

When using desiccants, the principle of using as much as you take should be followed to avoid prolonged exposure to the air and ensure their effective moisture absorption function. When using, the moisture absorption rate of the desiccant should be tested, as some desiccants may have been produced and stored for a long time, or have leaked air during production and transportation, resulting in the desiccant no longer having moisture absorption capacity. This ineffective desiccant cannot be used, otherwise it will not achieve the purpose of absorbing moisture and moisture.
