Food-grade adsorptive silica is a broad-spectrum food additive, with the international code E551 and China National Standard GB 2760 code 02.002. Produced via an ultra-high-purity precipitation method, it strictly adheres to global authoritative food standards such as GB 25576-2020, FDA 21 CFR, USP and FCC.

As a white, odorless and tasteless ultra-fine fluffy powder, the product features a three-dimensional network adsorption structure with high specific surface area and high porosity, boasting fast adsorption speed, stable capacity and strong selectivity. It can efficiently adsorb liquid components, trace impurities, free water and off-flavor substances in the food industry. Its heavy metal residues are far below international limits; it is non-reactive with various food components and produces no harmful substances. It can be dispersed or filtered out after addition with no residue left, making it a core broad-spectrum raw material for liquid solidification, impurity removal and product stabilization in the food industry.

1. Technical Specifications

2. Application Scope

As a broad-spectrum food additive for the food industry, this product's three-dimensional network adsorption structure is adapted to the adsorption needs of various food processing scenarios, with three core functions: liquid solidification, impurity adsorption and moisture-proof stabilization. It leaves no residue and does not affect the original flavor and nutrients of food, and is widely used in the processing of various food categories. Specific applications are as follows:

1. Oil adsorption: Applied in the refining of vegetable oil, animal oil and edible flavored oil to adsorb impurities, pigments and off-flavor substances and improve oil quality.

2. Liquid essence/essential oil solidification: Precisely adsorbs food-grade liquid essences and spice essential oils, converting them into free-flowing powder for easy mixing, storage and transportation.

3. Beverage/sauce clarification: Adsorbs trace impurities and free pectin in fruit juice, plant beverages and flavored sauces to improve product clarity and prevent precipitation.

4. Moisture proof for powdered food: Adsorbs free water in powdered food such as milk powder, meal replacement powder and condiments to assist in improving anti-caking properties and keeping products loose.

5. Nutrient carrier: Adsorbs fat-soluble vitamins, plant extracts and other nutrient components to achieve solidification and improve their dispersibility and stability in food.

3. Factory Advantages

1. Ultra-high purity control: The product's silica content is ≥98% with heavy metal residues far below international limits, meeting the high-purity requirements of high-end food processing.

2. Multi-scenario customization capability: Particle size and adsorption structure can be customized according to customers' food processing scenarios (adsorption/carrier/moisture proof) to optimize adsorption effect.

3. Complete international food certifications: The product has passed a number of international certifications such as FDA, HALAL and KOSHER, and can directly enter the world's mainstream food markets including the EU, North America and Southeast Asia.

4. Advanced testing equipment: Equipped with advanced equipment such as specific surface area analyzers, laser particle size analyzers and atomic fluorescence photometers for accurate testing of product adsorption performance, purity and heavy metals.

5. Full-process food safety guarantee: Produced in GMP standard production workshops with a 26-item full inspection process from raw materials to finished products to avoid manual contamination, complying with the highest safety standards for food additive production.

4. Shipping & Packaging

1. Standard packaging: 20/25kg food-grade paper-plastic composite bags with an inner food-grade PE sealing film and an outer waterproof and wear-resistant woven layer for double moisture proofing to isolate moisture and air.

2. Customized packaging: Custom packaging marks and multilingual food additive label printing are available to meet the needs of export customs declaration and brand identification.

3. Storage and transportation requirements: Non-hazardous chemical; store in a cool, dry, ventilated and dark environment, avoiding mixed storage with odorous food; compatible with global sea, air and land transportation with no special transportation requirements.

4. Labeling specifications: Each package is marked with statutory information including product name, specification, net content, production batch number, shelf life and food additive code (E551/02.002).

5. Frequently Asked Questions (FAQs)

Q: Is this product suitable for acidic food systems (such as fruit juice and vinegar sauces)?

A: Yes, it is. The product features stable performance in food systems with a pH of 3.0-8.0, insoluble and non-reactive with acidic components, and can be safely applied in the processing of acidic foods such as fruit juice and acidic sauces.

Q: Will the product damage the original flavor of essences when used as a carrier for liquid essences?

A: No. The product adopts physical adsorption, which only adsorbs liquid essences in the porous structure without chemical reaction with essence components. It can slowly release the essence flavor during food processing and maintain the original flavor characteristics.

Q: Will the addition of the product in powdered food cause a gritty taste?

A: No. The product is an ultra-fine powder with a particle size of 2-80μm and an extremely low dosage (≤1.5%), which can be completely dispersed in the mouth without causing a gritty taste or affecting food texture.

Q: Does the product meet the production requirements of vegetarian and halal food?

A: Yes. As an inorganic silicide, the product is produced without any animal-derived raw materials and has passed HALAL and OU KOSHER certifications, adapting to the production standards of vegetarian and halal food.
