Aflatoxin is highly carcinogenic, mostly in raw materials such as peanuts, corn and soybeans, and is the main harmful substance that affects the safety of edible oil. Crude oil squeezed by various processes must be refined（edible oil refining equipment） and detoxified before it can be sold.

1. Alkaline refining method

Adding alkali destroys the structure of aflatoxin, makes it soluble in water, and completely removes it by washing.

2. Ultraviolet irradiation method

The toxin is decomposed by ultraviolet rays, which is green and has no residue, and is suitable for all kinds of oil mills and small and medium-sized oil plants.

3. Physical adsorption method

White clay and activated carbon are used to adsorb toxin impurities in oil, and the oil can be purified by filtration and separation.

4. Organic solvent extraction method

The fat-soluble aflatoxin was extracted and separated by special solvent, and the crude oil was deeply purified.

Edible oil processing plants can flexibly match processes according to raw materials, toxin content and equipment configuration, effectively remove aflatoxin and ensure the safety and compliance of edible oil.
