Abstract
A method and adsorbent for increasing the life of edible oils are disclosed. The present method comprises substantially continuous treatment of edible oil with activated carbon during processes carried out at elevated temperature. The treatment may be by filtration through a filter means containing activated carbon or by immersion within the oil of an oil porous enclosure containing activated carbon. An adsorbent for substantially continuous use at elevated temperature is also disclosed. The adsorbent includes antioxidant impregnated activated carbons.
