METHOD FOR RECYLING BY-PRODUCTS BY MEANS OF THE RECONSTITUTION OF FATS USEFUL IN ANIMAL FEEDING-STUFFS

摘要

The invention describes the recycling of free fatty acids and/or of oleins as residual by-products from the refining of vegetable and/or animal fats. The reaction thereof with optionally residual glycerol or glycerine in turn originating from biodiesel production processes leads to reconstitution thereof as triglycerides or fats with fatty acid contents that are identical or similar to the starting vegetable and/or animal fats in the refining method that yields the residual fatty acids. The fats thus reconstituted, which are obtained by reconversion of the residual oleins and/or fatty acids, are used in animal feeding-stuffs and offer similar energy levels to those of natural fats.
