Abstract
A process is provided for treating an edible animal fat to reduce the content of components having free hydroxyl groups. The process comprises forming a reaction mixture from the fat and a cyclic anhydride such as succinic or glutaric anhydride, heating the mixture to a temperature promoting conversion of these components to hemisuccinates or hemiglutarates, and subjecting the reacted fat to alkali-refining to remove the converted components as water-soluble soaps. The process is particularly useful for reducing the cholesterol content of the animal fats.
