Food-grade silica gel can be used as an external drying agent for food and medicine. Because the edible silica gel is refined and sterilized, it can be mixed with food and medicine in the required amount to directly ensure that the food is dried and eaten together with the food, without any toxic side effects on the human body.
Edible silicone is mainly used for food molds, candy molds, cake molds and equipment with very stable dimensions, as well as carbon fiber composite materials and machine parts. The raw materials of this product have passed SGS environmental protection material certification.
The inorganic silica gel whose main component is SiO2·nH2O is the inorganic polymer colloidal material formed by polycondensation of silicic acid. SiO2·nH2O content is more than 98%, the surface is hydrophilic, and it has a strong absorption capacity for water. Under high humidity, its water absorption can reach 80%-100% of its own weight. Therefore, the silica gel can be used as an external desiccant for food and medicine.
There are many kinds of silica gel. There are daily-use silica gel and food-grade silica gel. If it is a plastic for filling and filling, he can not use it. The use of it will cause certain harm to the human body, but If it is food-grade silicone, then it can be eaten normally. This is harmless to the human body and has no side effects.
