Food-grade adsorptive silica for animal oil is a dedicated food additive developed to address the pain points of animal oil processing, with the international code E551 and China National Standard GB 2760 code 02.002. Produced via a high-purity precipitation method, it strictly adheres to global authoritative standards such as GB 25576-2020, FDA 21 CFR, USP and FCC.

The product features a targeted high-specific-surface-area adsorption structure, which can efficiently adsorb fishy substances, cholesterol oxides, trace protein impurities and heavy metal ions in edible animal oils including lard, beef tallow, chicken fat and duck fat. It is also adapted to the high saturation and high-temperature processing characteristics of animal oils with excellent thermal stability, without damaging the natural flavor and nutrients of animal oils. Its heavy metal residues are far below international limits. Treated animal oils are free of fishy smell, with bright color and improved stability, making it an exclusive raw material for refining, deodorization and purification of edible animal oils.

1. Technical Specifications

2. Application Scope

Exclusively designed for edible animal oil processing, this product targets and adsorbs unique impurities and fishy substances in animal oils with three core functions: deodorization, impurity removal and color enhancement. It has good thermal stability and adapts to the high-temperature boiling and refining processes of animal oils. Specific applications are as follows:

1. Edible lard refining: Applied in the high-temperature boiling and refining of edible lard to adsorb fishy substances and protein impurities, eliminate the raw fishy smell of lard and improve color clarity.

2. Poultry fat deodorization: Efficiently adsorbs unique fishy substances in chicken fat, duck fat and other poultry fats while retaining the meaty flavor of the oils, suitable for the processing of poultry fat for condiments.

3. Beef tallow/mutton tallow purification: Used in the refining of beef tallow and mutton tallow to adsorb cholesterol oxides and trace impurities, reduce oil off-flavors, and adapt to the processing of animal fats for baking and hot pot base materials.

4. Composite animal oil stabilization: Adsorbs free water and mixed oil impurities in composite animal oils to enhance the stability of the oil system and prevent rancidity and stratification during storage.

3. Factory Advantages

1. Dedicated deodorization formula for animal oils: Adsorption pores are optimized for the molecular structure of fishy substances in animal oils, achieving a deodorization efficiency of over 95% while retaining the natural meaty flavor of animal oils.

2. High-temperature stability R&D: The product is adapted to the high-temperature processing process of animal oils at 60-150℃, with no attenuation of adsorption performance after high-temperature treatment, no decomposition and no harmful substance production.

3. Precise impurity control: Aiming at the characteristic of animal oils being prone to containing heavy metal ions, the surface adsorption groups of the product are optimized to simultaneously adsorb trace heavy metal ions and improve oil safety.

4. Customized services: Particle size and adsorption performance can be adjusted according to customers' animal oil type and processing technology (boiling/refining), with small-scale sample testing available.

5. Full-process quality control: Equipped with professional equipment such as animal oil flavor detectors and heavy metal detectors to conduct dual testing on the flavor and safety of animal oils processed with the product.

4. Shipping & Packaging

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

2. Customized packaging: Custom packaging specifications and multilingual printing are available to meet the needs of brand identification, export customs declaration and warehouse management.

3. Storage and transportation requirements: Non-hazardous chemical; store in a cool, dry, ventilated and dark environment, avoiding high temperature, humidity and odor contamination; compatible with global sea, air and land transportation.

4. Labeling specifications: Each package is marked with statutory information including product name, specification, net content, production batch number and shelf life, accompanied by bilingual (English/Chinese) usage instructions.

5. Frequently Asked Questions (FAQs)

Q: Will the product remove the natural meaty flavor of animal oils after adsorbing fishy substances?

A: No. The product features targeted adsorption, which only adsorbs fishy substances (such as aldehydes and ketones) in animal oils without adsorbing flavor substances that reflect meaty flavor, achieving the effect of deodorization while retaining flavor.

Q: Is this product suitable for the refining of beef tallow for hot pot base materials?

A: Yes, it is. Aiming at the high-viscosity and strong-flavor characteristics of beef tallow for hot pot base materials, the product's adsorption particle size is optimized to remove impurities and off-flavors while retaining the mellow flavor of beef tallow, adapting to the processing requirements of hot pot base materials.

Q: Will an excessive dosage of the product affect the taste of animal oils?

A: No. The product dosage is controlled within 1.0%, and it is an inert inorganic powder that can be completely filtered out after adsorbing impurities, leaving no residue in animal oils and not affecting the taste and physical and chemical properties of the oils.

Q: Can the product reduce the cholesterol content in animal oils?

A: The product can adsorb cholesterol oxides (harmful impurities) in animal oils but does not adsorb natural cholesterol, improving the safety of animal oils while retaining their natural nutrient components.
