Fullers Earth Clay, Acid Activated Bleaching Earth for Cooking Oil

 The most important performance of activated clay is its adsorption and decolorization ability. There are two main forms of adsorption: physical adsorption and chemical adsorption. Van der Waals force is the force that produces physical adsorption. This force generally exists on the surface of adsorbent and between adsorbate molecules. It can remove organic pigments such as carotene, lutein, chlorophyll, phospholipids, lipopolysaccharides and harmful components such as aflatoxin and free gossypol from animal and vegetable oils; Chemisorption depends on the chemical bonds formed and has obvious selectivity, such as selective adsorption for impurities such as hydroxyl containing substances, trace metals (trace iron, copper, nickel, etc.) and soap like substances (calcium soap, magnesium soap, etc.); At the same time, it can also remove some oxidation products such as aldehydes, ketones and epoxides. It can decolorize, deodorize, detoxify and reduce the oxidation of edible oil, so as to improve the quality of edible oil and prolong its storage period. At present, it is widely used for decolorization of various animal and vegetable oils, such as soybean oil, rapeseed oil, peanut oil, cottonseed oil, sunflower oil, palm oil, coconut oil, castor oil, tea oil, corn germ oil, refined kernel oil, sesame oil, tung oil, safflower oil, etc.
