Non-Yellowing Food Grade Silica Dioxide | High-Purity Anti-Caking Agent for Food Processing Zhongqi Guangdong Silicon Material Co., Ltd. is a specialized manufacturer of food-grade precipitated silica dioxide, focused on solving a long-standing pain point in food manufacturing: color drift, yellowing and safety risks caused by conventional anti-caking agents. Our flagship non-yellowing silica formula delivers stable anti-caking performance while preserving the natural color, flavor and safety profile of food products, trusted by manufacturers across the baking, confectionery, spice and nutritional supplement sectors worldwide. 1. Product Advantages & Core Value Engineered for color-sensitive food systems, our food-grade silica dioxide effectively eliminates discoloration triggered by reactions between ethyl maltol and iron ions, enabled by industry-leading ultra-low heavy metal control and closed-loop production processes. Fully compliant with GB 25576-2010 and FDA 21 CFR standards, it delivers measurable benefits for production efficiency and end-product quality: •Exceptional UV & Heat Stability, Zero Yellowing With high-temperature resistance compatible with baking, spray drying and sterilization processes, plus outstanding UV stability, our silica maintains a pure white appearance throughout high-heat processing, transportation and full shelf life. It prevents yellowing or fading even in transparent packaging under long-term light exposure, protecting product aesthetics and brand consistency. •Ultra-High Purity with Trace-Level Heavy Metals Strict impurity control across the entire production chain keeps heavy metal contents at ultra-low levels, eliminating unwanted chemical interactions with flavors, pigments and active food ingredients. It avoids off-flavors, discoloration and potential safety hazards, fully meeting strict food safety requirements for high-end and export markets. •40%+ Enhanced Flowability & Anti-Caking Performance Optimized pore structure and surface morphology deliver superior anti-agglomeration effects, improving powder flowability by over 40% compared to standard food-grade silica. It reduces equipment clogging, cuts downtime for cleaning and maintenance, and improves packaging weighing accuracy and overall production efficiency. •Fully Customizable Particle Size for Targeted Applications Available in particle sizes ranging from 2μm to 50μm, with adjustable bulk density and optional surface treatment. We tailor specifications to match your product matrix — from fine spice powders, solid beverages and flavor blends to baking premixes and confectionery ingredients — ensuring optimal dispersion and performance. •End-to-End Technical Support We provide free pre-sales sample testing and formulation guidance, along with dedicated after-sales technical support to help optimize dosage and resolve on-site production issues. Our team supports compatibility testing and formula adjustment for special food systems. •Proven Global Market Compatibility Widely applied in baking mixes, hard candies, milk powders, instant drinks, seasonings, food flavors and nutritional supplements. Our products fully align with import regulations across Southeast Asia, Europe, North America and Oceania. 2.
