The removal of Polycyclic Aromatic Hydrocarbons (PAH) from edible oils and fats was pioneered by a leading American food company together with Green Leaf Carbons® – long before legal limits for PAH were set. We have developed special Green Leaf ‘PAH’ grades with unique specifications for PAH removal capacity, allowing the lowest dosing. These grades are widely used to purify rice bran, groundnut, coconut, palm, palm kernel, olive pomace, sunflower, and other vegetable oils.
