Silicon Dioxide, also known as Silicon Dioxide Gel or Silicon Dioxide Particles, is an inorganic compound with the chemical formula SiO2.In the food sector, Silicon Dioxide is widely used as a food additive.
The following are the main applications of silica in the food sector:
Anti-caking agent: Silicon dioxide has good hygroscopicity, which can absorb water in food and prevent food from caking. It is often added to powdered or granular foodstuffs, such as spices, desiccants, protein powders and coffee powders, to maintain their granular state and fluidity.
Anti-caking agent: Silica can form a micro-fine particle structure in food, increasing the adhesion and consistency of food. It is often added to foods such as beverages, desserts, confectionery and ice cream to improve their texture and mouthfeel.
Adsorbent: Silicon dioxide has a large specific surface area and adsorption capacity, which can adsorb impurities, pigments and off-flavour substances in food and improve the purity and quality of food. It is often used in clarification, filtration and purification steps in food processing.
Carrier and stabiliser: Silica can be used as a carrier and stabiliser for food additives. It stabilises the properties and activity of other additives and helps to disperse them evenly in the food. Common examples include nutritional supplements, flavours and seasonings.
It is important to note that the use of silica in food should be in accordance with relevant regulations and standards and follow appropriate dosage and use recommendations. Silicon dioxide itself is harmless, but its ingestion in large quantities may cause effects on human health. Therefore, the principle of safe use should be followed when used in food.
