Food Grade Adsorbent Silica (INS E551, coded as 02.002 in China National Food Safety Standard GB 2760) is a professional adsorption auxiliary complying with international food additive standards. Manufactured via an improved precipitation process, it strictly adheres to authoritative global standards including the Chinese National Standard GB 25576-2020, FDA 21 CFR, USP, and FCC.

Based on high-purity silica, the product features a three-dimensional porous network adsorption structure, boasting core properties of a high specific surface area, rapid adsorption, and stable adsorption capacity. Its heavy metal residues are far below international limits; it is odorless, non-irritating, and non-reactive with all food ingredients. It is an excellent raw material for solidification of liquid components and impurity adsorption in the food industry.

1. Technical Specifications

2. Product Applications

Relying on its exclusive porous adsorption structure, Food Grade Adsorbent Silica mainly achieves two core functions: high-efficiency adsorption and carrier solidification. It is widely used in various adsorption scenarios of food processing, suitable for the stabilization and pulverization of liquid food components. Specific applications are as follows:

1. Adsorption of liquid flavors/essential oils: Precisely adsorbs food-grade liquid flavors and spice essential oils, converting them into free-flowing powder for easy mixing, storage and transportation without damaging the original flavor of the flavors.

2. Adsorption of oils/fat-soluble nutrients: Adsorbs vegetable oils, fat-soluble vitamins (A/D/E), plant extracts, etc., to realize solidification and improve the dispersibility and stability of products.

3. Food impurity adsorption: Adsorbs trace impurities and free water in the processing of beverages and sauces, optimizing product clarity and taste, and extending shelf life.

4. Moisture proof for powdered food: Adsorbs free water in powdered food, helps improve anti-caking performance and keep products loose, suitable for solid beverages, condiments, meal replacement powders and other categories.

The dosage in all application scenarios complies with the usage limits of food additives in all regions worldwide, leaving no residue and without affecting the original physical and chemical properties of food.

3. Factory Strengths

4. Packaging & Shipment

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

2. Custom packaging: Support customers to customize packaging specifications and print shipping marks to meet the needs of brand identification and export customs declaration.

3. Storage and transportation requirements: Non-hazardous chemicals; store in a cool, dry, ventilated and dark environment to avoid rain and high temperature. Global sea, air and land transportation are supported with no special requirements for the transportation process.

4. Labeling specifications: Each package is marked with statutory information such as product name, specification, net content, production batch number, shelf life, food additive mark and production license number.

5. Frequently Asked Questions (FAQs)

Q: Is the adsorption effect of adsorptive silica reversible?

A: No, it is irreversible. The product adopts physical adsorption and forms a stable solid complex after adsorption. The adsorbed substances will not be released under conventional food processing and storage conditions, ensuring product stability.

Q: Is this product suitable for acidic food systems?

A: Yes. The product performs stably in food systems with a pH of 3.0-8.0, insoluble and non-reactive, and can be applied to fruit juices, acidic solid beverages and other categories.

Q: How to determine the optimal dosage?

A: Our technical team can provide professional guidance according to customers' adsorption objects and process conditions, and the optimal addition ratio can also be determined through laboratory small-scale tests. Free technical support is available.

Q: Does the product meet vegetarian and halal requirements?

A: Yes. No animal-derived raw materials are used in the production process, and the product has passed HALAL and OU KOSHER certifications, adapting to various food production standards worldwide.
