Food with silica gel is made from silicate polycondensation of inorganic polymer gel material, ingredient is SiO2nH2O, its content in 98 %, avirulent insipidity, stable chemical performance, under the normal except hydrofluoric acid and caustic alkali, not any response from the acid and alkali salt.
Since it is a kind of colloid structure, so lots of pores and large specific surface area.
Edible silica gel pore size of about 8 to 10 nm, specific surface area of 300-500 m2 / g, and surface water, the water has very strong absorption ability, under the condition of high humidity the water absorbing capacity can reach 80 %-100% their own weight .
So the food grade silica gel can be used as food, medicines for external use desiccant.
Due to consumption of silica gel is a refined and after sterilization, can be directly when mixed with the food and drug according to the requirement and guarantees the drying of food and food to eat together, and on the human body without any side effects.
