Use as feed for crustaceans of a residue in the distillation of crude fatty acids as well as the use of this residue for the manufacture of feed for crustaceans

Abstract

A residue in the distillation of crude fatty acids is used as a food for crustaceans. The fatty acids utilized in the distillation are obtained from hydrolysis of natural, chiefly animal, fats. Sterols have a higher boiling point than the fatty acids and are therefore not distilled. This gives the residue a much higher cholesterol content than the fatty acids and makes it eminently suitable as feed for crustaceans. The residue can be used directly as feed for crustaceans or first a carrier of protein and/or silicate can be added to the residue, with preferably lecithin also being added to the residue.
