Food-grade silicone is an inorganic, polymer colloidal material that is made by condensing silicic acid. Silica gel has a pore size of about 8-10nm, a specific surface area of 300-500m2/g, and a hydrophilic surface that strongly absorbs water. It can absorb more than 80%-100% of its weight in water under high humidity. Due to this property, food-grade silica gel is commonly used as an external desiccant for food and medicine. It is refined and sterilized for edible use, which means that it can be mixed with food and medicine to ensure that it remains dry. Moreover, it can be consumed safely without any toxic side effects on the human body.
