Food-grade silica is a high-purity, amorphous (amorphous) white powder or particle that is designed for the food industry and complies with global food safety standards (e.g. FDA 21 CFR §172.480, EU 231/2012). As a multi-functional food additive, it is wi
Food-grade silica is a high-purity, amorphous (amorphous) white powder or particle that is designed for the food industry and complies with global food safety standards (e.g. FDA 21 CFR §172.480, EU 231/2012). As a multi-functional food additive, it is widely used in the fields of anti-caking, desiccant, carrier and processing AIDS, etc., safe and non-toxic, suitable for all kinds of food processing links.
