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 fro m liquid anhydrous animal fats is described. The process uses a dilute solution of alkali metal base to form a salt of the FFA and th en an alkali metal salt to precipitate the FFA from the animal fat. Preferably, a cyclodextrin is used in the process to remove cholesterol . Liquid vegetable fats are used in blends with the processed animal fat to produce a spreadable mixture for table use. The processed anim al fat can be reconstituted to whole milk with the FFA and cholesterol removed for various commercial uses.
