Silica gel for food is an inorganic polymer colloidal material made of silicic acid polycondensation, the main ingredient is SiO2·nH2O, its content is more than 98%, non-toxic and tasteless, stable chemical performance, in normal conditions in addition to caustic soda and hydrofluoric acid, with any acid, alkali salt reaction. Because it is a colloidal structure, it has many micropores and a large specific surface area.

The pore diameter of edible silica gel is about 8-10nm, and the specific surface area is 300-500m2/g. Moreover, the surface is hydrophilic and has a strong absorption capacity of water. In the case of high humidity, the water absorption capacity can reach more than 80%-100% of its weight. So food grade silica gel can be used as a desiccant for food and medicine. Because the edible silica gel is refined and sterilized, it can be mixed with food and drugs according to the required amount and directly ensure that the food is dry and eaten with food, without any toxic and side effects on the human body.

Main features of silica gel for food

1. Non-toxic, odorless, high transparency, no yellowing;

2. Soft, elastic, kink resistance without deformation;

3. No cracking, long service life, cold and high temperature resistance;

4. Higher tear strength and superior electrical performance;

It has the advantages of high transparency, tasteless, constant yellow, no frosting, especially to solve the black hose frosting, blue products fade, soft, high tear resistance, high insulation, wear resistance, high temperature resistance, flame retardant, anti-aging, environmental protection, tensile type, stable performance and other advantages.
