Is transparent silica gel desiccant toxic in food?


Transparent desiccant is called silica gel desiccant or glass desiccant. The silica gel desiccant is easy to absorb water. The desiccant is non-toxic and environmentally friendly. Several kinds of desiccants commonly used in daily life: silica alumina gel with transparent particles, lime and mineral desiccant. Silica gel desiccant is an environment-friendly, non-toxic and moisture-proof product. The product quality completely meets the environmental requirements of RoHS, reach and other environmental protection requirements. It does not contain harmful substances, such as DMF (dimethyl fumarate).

Silica gel desiccant is a kind of high active adsorbent material. After some treatment, silicic acid is a kind of amorphous substance. Its chemical formula is msio2, nH2O, without water and any solvent. It is non-toxic and tasteless. The chemical properties of silica gel desiccant are stable. Because of its different manufacturing methods, different types of silica gel have different microporous structures. The chemical and physical structure of silica gel determines that it has many characteristics that are difficult to replace other similar materials: strong adsorption, good thermal stability, stable chemical properties and other safety properties.


   Silica gel desiccant is a physical adsorption desiccant. Silica gel absorbs water in air through physical adsorption principle, and does not react with water. There are many types of desiccants, including physical adsorption and chemical adsorption. Chemical adsorption of calcium oxide, calcium chloride or phosphorus pentoxide, silicic acid. Physical adsorption: silica gel, montmorillonite, minerals, etc.
