Food Grade Silicone Introduction

- Apr 21, 2018-

  Silicone for food use is an inorganic polymer colloidal material made of polycondensation of silicic acid. Its main component is SiO2·nH2O, its content is more than 98%, non-toxic and odorless, its chemical properties are stable, and it is normally removed except caustic alkali and hydrofluoric acid. Does not react with any acid-base salts. Because it is a colloidal structure, it has many micropores and a large specific surface area. Edible silica gel pore size is about 8-10nm, specific surface area is 300-500m2/g, and the surface is hydrophilic, it has strong absorption ability to water, and its water absorption capacity can reach 80%-100% of its own weight under high humidity conditions. . Therefore, food-grade silicone can be used as an external desiccant for foods and pharmaceuticals. Since the edible silica gel is refined and sterilized, it can be directly mixed with the food and medicine according to the required amount to directly ensure the food is dried and eaten together with the food, without any toxic side effects on the human body.
