ABSTRACT:
The autoxidation resistance of an animal or vegetal fat or oil containing trace amounts of heavy metals which catalyze the autoxidation can be improved by contacting the fat or oil with solid citric, malic, or tartaric acid at a temperature below the melting point of the acid, and thereafter separating the acid particles from the fat or oil.
