A process for removing free fatty acids (FFA) and preferably cholesterol from liquid anhydrous animal fats is described. The process uses a dilute solution of alkali metal base to form a salt of the FFA and then 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 animal fat can be reconstituted to whole milk with the FFA and cholesterol removed for various commercial uses.

L'invention concerne un procédé pour retirer les acides gras libres et de préférence le cholestérol des graisses animales anhydres liquides. Le procédé consiste à utiliser une solution diluée d'une base de métal alcalin pour former un sel d'acide gras libre et ensuite un sel de métal alcalin pour précipiter cet acide gras libre à partir de la graisse animale. De préférence, on utilise une cyclodextrine pour retirer le cholestérol. Les graisses végétales liquides sont utilisées dans des mélanges avec la graisse animale traitée pour produire des pâtes à tartiner . La graisse animale traitée peut être reconstituée en lait entier avec l'acide gras libre et le cholestérol retiré pour diverses applications commerciales.
