Zhongqi Guangdong Silicon Materials Co., Ltd. specializes in the R&D and production of food-grade silica, complying with GB 25576-2020 and FDA standards. The product features high purity (silica content ≥99%) and low heavy metal content, with customizable particle sizes and specifications. Operating from its own factory, it maintains stable production capacity. Its heavy metal residues (lead ≤0.1mg/kg, arsenic ≤1ppm) are significantly below international safety limits, while lead (≤5ppm) and arsenic (≤2ppm) levels meet stricter global standards. With extensive export experience, the company employs molecular-level processes to achieve exceptional anti-caking, flow-enhancing, and adsorption properties.

Application description

As a key anti-caking agent in the food and health products industry, Zhongqi Food-grade Silica is the preferred raw material for high-end food manufacturers. It strictly complies with standards such as China GB 25576-2020 and the U.S. FDA, ensuring 100% safe consumption. The product boasts outstanding core quality with silica content ≥99.5%, while harmful heavy metals like lead, arsenic, and mercury are ≤5ppm—significantly below regulatory limits—thereby eliminating potential safety risks. It appears as a white, odorless, and tasteless ultra-fine powder with excellent dispersibility that does not react with food components. The material maintains stable performance across-40℃ to 200℃ temperatures and adapts to various processing techniques. Its applications span multiple categories including solid beverages, flavorings, condiments, dairy products, baking ingredients, cocoa products, vegetable fat powder, and dehydrated egg products.

The anti-caking agent silica of Zhongqi achieves three core functions through microstructure design:

1.Anti-caking: Add 0.1%-2% in salt, sugar powder and other powder products to completely solve the problem of hard lumps formed in product storage and keep the product loose;

2.Liquidity optimization: significantly reduce the friction between powders, so that the weight error of milk powder, cocoa powder and so on in the filling process is controlled within ±2%;

3.Dispersed uniformity: help the trace additive to be evenly distributed in the food base material, avoiding high local concentration.

4.This additive is widely used in various applications including solid beverages, flavorings and spices (such as salt and chicken bouillon), dairy products (including milk powder and whey protein), baking ingredients (like flour and premixed powders), cocoa-based products (produced from cocoa beans into fats, powders, pastes, sauces, and fillings), vegetable fat substitutes, dehydrated egg products (e.g., egg white powder, egg yolk powder, and egg white flakes), other sweeteners (specifically sugar powder), alternative dairy products (mainly whey powder and protein-based dairy tablets), and creamer powders. The dosage specifications for these applications strictly comply with international standards.

Factory advantages

Zhongqi Guangdong Silicon Materials Co., Ltd., a national high-tech enterprise and provincial-level specialized, refined, unique, and innovative enterprise, has been dedicated to the industry for over two decades. The company holds 17 patented technologies and operates a GMP-certified production base. Equipped with advanced testing instruments including atomic fluorescence spectrometers and laser particle analyzers, it has established a comprehensive quality control system comprising 26 inspection processes from raw materials to finished products. The company has obtained ISO22000 certification for food safety management systems.

Its core strengths include:

•Customized particle size design: customize particle size distribution according to different food characteristics (such as hygroscopicity and particle size) to optimize anti-clumping efficiency;

•Whole-process quality control: closed-loop testing from raw materials to finished product packaging is implemented to ensure that the difference of purity in each batch is less than or equal to 0.5%;

•Intelligent production: 10,000-ton automated production line to achieve continuous production, avoid the risk of artificial pollution;

•Compliance assurance: ISO22000, FDA and other certifications, products can directly enter the European Union, North America and other mainstream markets.

Packing for shipment
•Standard packaging: 10/15/20kg valve paper bag/woven bag (customizable).
•Waterproof design: the packaging adopts composite film valve bag + a layer of PE on the outside; or PE inner film bag + plastic woven bag, and strictly do a good job in protection to prevent water intrusion.
•Storage and transportation requirements: store in cool and dry environment, shelf life of 24 months; non-hazardous chemical, support global shipping/air transportation.
•Labeling standards: each package shall be marked with legal information such as food additives, added limits and production license number, or the label head shall be posted according to customer requirements.

Frequently Asked Questions

Q: Will adding anti-caking agent silica affect the taste of food?
A: No. The product particle size is small and the addition amount is very low (≤2%), which can be completely dispersed in the mouth without producing a sense of sand particles.

Q: Does it meet halal/Jewish food requirements?
A: Yes, the product is halal and OU KOSHER certified, and no animal source ingredients are used in the production process.

Q: How to determine the best addition ratio?
A: The technical team can provide guidance based on product characteristics and rich downstream application experience, and can also determine the optimal dosage and optimize the formula by accelerating the lumping experiment.
