Silica Gel for Edible Oil Deacidification
Classification :
Adsorbent Silicon Dioxide
Keywords :
Silica Gel for Edible Oil Deacidification
PRODUCT DETAILS
This is a food-grade high-activity silica gel exclusively for deacidification, with the International Numbering System E551. It appears as a white porous powder, odorless and tasteless, and is prepared via a free fatty acid (FFA) selective adsorption process. Compliant with FDA GRAS, EFSA E551 and EU 1333/2008 standards, it has a SiO₂ content of ≥99% and features high targeted adsorption capacity for FFAs in edible oil, boasting a world-leading deacidification efficiency. It does not adsorb beneficial nutritional components in oil, nor alter the natural properties of oil products. This product is suitable for all edible oil deacidification and refining scenarios worldwide, and is particularly tailored to the low acid value processing requirements of high-end edible oils.

2. Application Description
Its core function is precision deacidification of edible oil. It can efficiently adsorb various FFAs (including palmitic acid, oleic acid, linoleic acid, linolenic acid) in soybean oil, rapeseed oil, olive oil, animal fat and other edible oils, rapidly reducing the oil acid value to meet the deacidification standards of the EU, North America and other international regions. Meanwhile, it mildly adsorbs trace gums and hydrophilic impurities in oil without damaging nutritional components such as vitamins, sterols and unsaturated fatty acids, and without affecting the natural flavor and color of oil products.
Suitable for physical deacidification of edible oil, auxiliary use in chemical deacidification, and customized low acid value processing of high-end edible oils, it simplifies the deacidification process, reduces the dosage of deacidification additives, and lowers the processing costs for enterprises.

5. Frequently Asked Questions
Q: What types of free fatty acids can this product adsorb?
A: It can efficiently adsorb various FFAs in edible oil such as palmitic acid, oleic acid, linoleic acid and linolenic acid, with a deacidification efficiency of ≥99%. It can stabilize the oil acid value at below 0.1mgKOH/g, meeting the EU high-end edible oil standards.
Q: Can it be used as an auxiliary additive in the chemical deacidification process?
A: Yes. As an auxiliary additive for chemical deacidification, it can adsorb trace by-products generated during the deacidification reaction, further reduce the oil acid value to enhance deacidification effects, decrease the dosage of chemical reagents, and lower the risk of chemical residues in oil products.
