ZLSIL-T38A Ultra-High Purity Food Grade Amorphous Silica
Product Overview
ZLSIL-T38A is an ultra-high purity, ultra-fine food grade amorphous silica (E551 anti-caking agent) developed by Zhongqi (Shandong) Silicon Materials Co., Ltd. using proprietary refined purification precipitation technology. It is specifically designed for the most demanding applications in the food industry, including infant formula, special medical purpose foods, and premium health supplements, where safety and purity are of paramount importance.
This product complies with GB 2760, GB 25576-2020, FDA 21 CFR, and EFSA standards, with a minimum silica content of 99% on a dry basis. It contains no crystalline impurities and offers exceptional anti-caking, flow enhancement, and dispersion properties, making it the gold standard for food applications requiring the highest levels of safety and performance.
Core Functions & Applications
Core Functions
• Exceptional Long-Term Anti-Caking Protection: Its ultra-fine amorphous microstructure creates an extremely effective barrier against inter-particle molecular forces and moisture absorption, providing long-lasting anti-caking performance for high-value, high-activity food powders. This ensures product quality remains stable throughout the entire shelf life.
• Ultra-Precision Flow Control: Dramatically reduces inter-particle friction to deliver unmatched flow control for high-viscosity, high-activity powders. It maintains filling weight accuracy within ±1% for high-precision automated production lines, improving finished product yield and quality consistency for premium products.
• Superior Dispersion for Active Ingredients: Excellent dispersibility ensures even distribution of trace nutrients, high-activity probiotics, and functional ingredients throughout the powder matrix. This prevents localized concentration variations and protects sensitive active ingredients from degradation, preserving product functionality and efficacy.
• Uncompromising Safety Compliance: With no crystalline impurities and ultra-low levels of heavy metals, arsenic, lead, and microorganisms, it meets the most stringent safety requirements for infant foods and special medical purpose foods. When used within specified dosage limits, it does not alter the original flavor, color, or nutritional properties of food products.
Key Application Areas
Suitable for food applications requiring the highest levels of purity, safety, and stability:
• Maternal and infant foods: Infant formula milk powder, infant supplementary foods, special medical purpose infant formula powders
• Premium health supplements: Probiotic powders, lactoferrin powders, peptide powders, functional health supplements, special medical purpose formula powders
• Ultra-premium foods: Imported high-protein powders, luxury meal replacement powders, artisanal coffee powders, freeze-dried rare fruit and vegetable powders
• Other applications: High-end food flavors, high-activity nutritional fortifiers, premium compound food additives
Product Advantages
• Optimized for High-Safety Applications: Developed specifically to meet the extreme safety and performance requirements of infant foods and special medical purpose foods, its key purity, particle size, and dispersion properties are tailored for these demanding applications. Customers can integrate this product into their existing premium production lines with minimal adjustments, helping reduce development time and regulatory compliance costs.
• Ultra-High Purity with No Crystalline Impurities: Using proprietary refined purification technology, it achieves a minimum 99% pure amorphous silica core with no crystalline silicon impurities. Heavy metal and other harmful residues are far below the limits set by Chinese, EU, and FDA standards, making it suitable for the most sensitive food applications. We provide special high-purity test reports for regulatory compliance.
