2022-07-18

We often see a small package in snack bags, that is, food desiccants, which are widely used in food. What are the main ingredients of these desiccants?

There are four main types of food desiccants: silica gel desiccants, montmorillonite desiccants, fiber desiccants and quicklime desiccants, which have their own advantages and disadvantages, but most food uses silica gel desiccants.

As far as silica gel desiccant is concerned, it is a kind of transparent round bead particles. The main raw material is silica, which is insoluble in water, non-toxic and tasteless, and can be in direct contact with food. It mainly includes transparent silica gel, blue silica gel and orange silica gel. It is a relatively environment-friendly and safe desiccant. Silica gel desiccant is a kind of physical desiccant, which is dried by physical adsorption with water.

For food, under a certain temperature and humidity, food is easy to produce bacteria, causing food to become damp and deteriorate. Therefore, with these food desiccants, we can well avoid this series of problems.
