METHODS TO REDUCE FREE FATTY ACIDS AND CHOLESTEROL IN ANHYDROUS ANIMAL FAT

摘要

A process for removing free fatty acids (FFA) and preferably cholesterol fromliquid anhydrous animal fats is described. The processuses a dilute solution of alkali metal base to form a salt of the FFA and thenan alkali metal salt to precipitate the FFA from the animalfat. Preferably, a cyclodextrin is used in the process to remove cholesterol.Liquid vegetable fats are used in blends with the processedanimal fat to produce a spreadable mixture for table use. The processed animalfat can be reconstituted to whole milk with the FFA andcholesterol removed for various commercial uses.
