Application of Food-Grade Silicon Dioxide in Pet Food: Dual Value of Moisture Proof and Nutrition Stability
Pet food (especially dry food and nutritional supplements) is prone to reduced palatability and compromised safety due to moisture absorption, mold growth and nutrient loss.
Pet food (especially dry food and nutritional supplements) is prone to reduced palatability and compromised safety due to moisture absorption, mold growth and nutrient loss. Food-grade silicon dioxide has become a key additive to improve product quality. Adding 0.1%–0.2% to pet dry food can adsorb free moisture, control the moisture content below 10%, inhibit the growth of aflatoxins, and extend the shelf life from 6 months to 12 months.
As a nutritional carrier, it can stabilize trace components such as vitamins and minerals: liquid vitamins A and D are adsorbed into the porous structure of silicon dioxide and converted into stable powder to avoid oxidative degradation, increasing the vitamin retention rate by more than 30%. To meet the palatability requirements of pet food, the product undergoes odorless treatment and does not affect pets’ willingness to eat.
The company’s product advantages lie in compliance and adaptability: it complies with the U.S. AAFCO (Association of American Feed Control Officials) standards and EU FEEDAP regulations, with a heavy metal content of less than 5 mg/kg. The developed "pet-specific" silicon dioxide has a moisture absorption rate of 25% (mass ratio), 10% higher than the industry average. It has been supplied to high-end pet food brands such as Royal Canin and Orijen, and provides "formula compatibility testing" services to ensure synergy with meat ingredients, probiotics, and other additives.
