  • Removal of benzopyrene from edible oils using an activated carbonized adsorbent
    Patent number: 5218132
    Abstract: Adsorbents suitable for use to remove aromatic or polyaromatic hydrocarbons from liquids such as oils may be produced from an acid-activated siliceous clay containing adsorbed oil by treating to carbonize the oil and to activate the carbon so produced on the surface of the clay. The carbonization and activation steps may be conducted by heating in the presence of an activating agent which may be zinc chloride. Preferably zinc chloride activated material is subsequently steam-treated.The invention is particularly useful to reduce the content of hazardous polyaromatic hydrocarbons, such as benzo(a)pyrene, from edible oils.
