Cold-pressed Silica Adsorbent for Vegetable Oil
PRODUCT DETAILS
1 Product Description
This silica adsorbent is specially developed for cold-pressed vegetable oil, with the international food additive code E551. It appears as odorless, tasteless white porous powder, complying with FDA GRAS, EFSA E551 and EU 1333/2008 standards. The SiO₂ content reaches ≥99.3%, and its adsorption performance remains intact at low temperatures ≤10℃, with all indicators verified by constant-temperature laboratory tests. Customized for cold-pressed olive oil, linseed oil, camellia seed oil and other cold-pressed oils, it gently removes gums, waxes and trace micro-impurities. It only adsorbs polar impurities selectively without destroying natural nutrients including unsaturated fatty acids and vitamins, fully retaining the original flavor of cold-pressed oil. Our products are steadily exported to cold-pressed oil manufacturers across 58 countries, meeting the export processing requirements of high-end cold-pressed vegetable oil worldwide.

3 Product Applications
Its core advantages lie in low-temperature resistance and mild impurity removal, developed based on real application experience from hundreds of cold-pressing factories. Compatible with all mainstream low-temperature squeezing and physical cold-pressing processes, it solely removes gums, waxes and suspended impurities without loss of natural nutrients and fruity aroma of oil. It has been mass-supplied to overseas production lines of organic cold-pressed olive oil and linseed oil, solving the industry pain points such as turbidity and wax precipitation of cold-pressed oil at low temperatures. Desensitized customer records of all application cases can be provided for verification.

6 Frequently Asked Questions (FAQs)
Is it compatible with all cold-pressed vegetable oil processes? A: It fits all mainstream low-temperature physical cold-pressing and low-temperature squeezing processes with numerous real mass-production cases. The dosage can be fine-tuned based on measured data of different oil seeds. Q: Will it damage the natural nutrients of cold-pressed oil? A: No. Third-party comparative tests of oil nutrients prove that the product only adsorbs impurities without obvious reduction in retention rate of unsaturated fatty acids and fat-soluble vitamins. Original test data can be provided.
