ZLSIL-W500F Food Grade Silicon Dioxide (Carrier Grade)
Product Description
ZLSIL-W500F is a high-performance carrier grade silicon dioxide (SiO₂, INS No. E551) specifically designed for use as a carrier, adsorbent, and dispersant for liquid and semi-solid food additives. Manufactured using a proprietary pore-forming process that creates a highly porous structure, it meets all major global food safety standards including GB 2760, GB 25576, FDA 21 CFR 172.480, EU Regulation 1333/2008, USP, and FCC. This white, highly fluffy powder features exceptional adsorption capacity (≥150 ml/g) and operates primarily through physical adsorption, ensuring no chemical reaction with the loaded additives. It is ideal for converting liquid food ingredients into stable, free-flowing powder forms and improving the dispersion of solid additives in food matrices.
Application Guidelines
• Flavor & Color Carriers: Converts liquid flavors, essential oils, oleoresins, and natural food colorings into free-flowing powders, reducing volatility, extending shelf life, and preventing agglomeration. This ensures uniform flavor and color distribution in food products such as snacks, baked goods, and beverages.
• Nutritional Additive Dispersants: Improves the dispersion of fat-soluble vitamins (A, D, E, K), minerals, amino acids, and probiotics in food formulations, preventing segregation and ensuring consistent nutrient levels in every serving.
• Functional Additive Systems: Enhances the performance of preservatives, antioxidants, and enzyme preparations by increasing their surface area and improving their contact with food matrices, reducing required dosage levels and improving efficacy.
Production Advantages
• Proprietary high-adsorption manufacturing process allows precise control over pore size, pore volume, and surface area, enabling customization for specific additive loading requirements.
• Dedicated adsorption performance testing laboratory ensures consistent quality and compatibility with a wide range of food additives, including both hydrophilic and hydrophobic substances.
• Our R&D team provides customized formulation support, helping customers optimize loading ratios, improve powder flow, and extend the shelf life of their additive blends.
Packaging, Storage & Transportation
• Packaging: 5kg/10kg/20kg vacuum-sealed aluminum foil bags to prevent moisture absorption and preserve adsorption capacity during storage and transportation.
• Storage & Transportation: Store in a cool, dry, well-ventilated area away from direct sunlight, strong odors, and volatile substances. Keep containers tightly sealed when not in use to prevent contamination and loss of adsorption properties. Non-hazardous classification allows for standard global transportation.
• Labeling: Custom labels available with detailed product specifications, adsorption capacity information, and multilingual regulatory compliance details for international markets.
Frequently Asked Questions
Q: What is the maximum loading capacity of ZLSIL-W500F for liquid additives?
A: The maximum loading capacity varies depending on the viscosity and surface tension of the liquid additive, but typically ranges from 1:1 to 2:1 (additive to silica ratio). Our technical team can conduct loading tests to determine the optimal ratio for your specific application.
Q: Will it affect the functionality or release profile of the loaded additives?
A: No, ZLSIL-W500F works exclusively through physical adsorption and does not undergo any chemical reactions with the loaded additives. This preserves the original functionality, flavor, and release profile of the food additives.
Q: Is ZLSIL-W500F safe for use in infant formula and baby food products?
A: Yes, ZLSIL-W500F complies with all relevant safety standards for infant formula and baby food, including GB 2760 and EU Regulation 1333/2008. When used within the recommended dosage limits, it is safe for consumption by infants and young children.
