4.1. Fumed silica is a colorless, odorless and non-toxic ultra-fine inorganic new material, which is widely used in people's production and life. As a food additive, the main function of fumed silica is to prevent powder food from caking and improve its fluidity, so as to maintain the good appearance of powder food

4.2. After being added to food, due to its large specific surface area, silica will act as a "film" to wrap the powders, so that the powders are separated from each other and are in the best free-flowing state. To achieve the purpose of anti-caking. At the same time, silica can absorb the moisture in the surrounding air with countless internal pores, preventing the food from being damp and agglomerated during storage.
