ZLSIL-PS300 Universal Food Grade Precipitated Silica | E551 Anti-Caking Agent & Flow Aid

Core Product Overview

ZLSIL-PS300 is an independently developed basic universal food-grade precipitated silica (international food additive code E551) by Zhongqi (Shandong) Silicon Materials Co., Ltd. Manufactured via advanced precipitation process tailored to mainstream industry technical indicators and application scenarios, it serves as a highly stable and cost-effective domestic alternative for conventional food processing needs.

This product strictly complies with China's GB 2760 and GB 25576-2020 national standards, and also meets USP, FCC international food chemical specifications. With a minimum SiO₂ purity of 96%, it delivers dual core functions of anti-caking and flow aid. Featuring fine texture and excellent dispersibility, it is universally compatible with most powdered food processing systems and is completely safe for use within the national standard dosage limits.

Core Functions & Application Scenarios

Core Functions

1. Dual-Function Performance: Simultaneously provides reliable anti-caking protection and efficient flow improvement. Its unique microstructural design creates physical barriers between powder particles to prevent moisture-induced agglomeration, while reducing inter-particle friction to optimize filling flowability and meet basic production requirements of food enterprises.

2. Universal Matrix Compatibility: The ultra-fine powder disperses rapidly and uniformly in various food systems without altering the original flavor, color, or texture of the final product. No gritty sensation is perceived at recommended dosages, making it suitable for nearly all conventional powdered food formulations.

3. Regulatory Compliance & Batch Consistency: Manufactured in strict accordance with national food safety regulations with full traceability throughout the production chain. Low impurity levels and consistent batch-to-batch performance ensure reliable operation for large-scale continuous production lines.

Primary Application Fields

Widely used in processing of various conventional powdered foods, including:

• Solid beverages: Fruit and vegetable powders, coffee powder, instant tea powder, regular meal replacement powders

• Condiments: Table salt, powdered sugar, monosodium glutamate, spice powders, compound seasonings

• Dairy products: Regular milk powder, creamer, non-dairy creamer

• Baking ingredients: Flour, cocoa powder, yeast powder, baking premixes

• Other categories: Food flavorings, compound food additives and other conventional powder systems

Key Product Advantages

1. Industry-Aligned Performance for Broad Adaptability: Developed based on mainstream technical parameters and application requirements of the global food industry, its key performance indicators and powder characteristics perfectly match conventional food processing needs. It can be directly integrated into existing anti-caking and flow aid addition processes and formulation systems, helping customers optimize supply chain costs and delivery stability.

2. Stringent Quality Control for Consistent Performance: The entire production process follows strict food additive manufacturing specifications, equipped with high-precision testing equipment. A full-chain inspection system from raw material incoming to finished product delivery minimizes batch-to-batch variations, ensuring stable supply for large-scale food production.

3. Exceptional Cost-Effectiveness with Wide Compatibility: With ≥96% high-purity silica base, low impurities and neutral pH value, it exhibits excellent compatibility with various food raw materials without adverse reactions. The large-scale production line provides sufficient capacity and competitive pricing to meet bulk purchasing demands.

4. End-to-End Technical Support for Seamless Implementation: Our professional food application technical team provides compliance-based dosage recommendations, assists in formula debugging and application testing, and offers full follow-up support to resolve any technical issues during product implementation.
