High performance activated white clay is an adsorbent made from Bentonite as raw material, which is treated with inorganic acid, rinsed with water, and then dried to get final product. It is white powder, odorless, tasteless, non-toxic, with good adsorption property to adsorb colored substances and organic matter. It is mainly used for refining the animal and vegetable oil, to effectively remove the aflatoxin, pesticide residue and the odor substance from the oil, as well as phospholipids, soaps and trace of metal ions. The decolored oil’s acid value will not go up again. The oil is clear and transparent, and will not be colored again. This high performance activated white clay is particularly suitable for refinery production of vegetable oil, animal oil and mineral oil.
