Abstract

A convenient laboratory method has been worked out for defatting of lecithin preparations. It is based on micellar filtration of a petroleum solution of phospholipids through twice the weight of silica gel, which not only removes glycerides and fatty acids completely, but also sterols and their esters, sterolglycosides and their esters, peptides and organic dyestuffs. The amount of free sugars and amino acids is simultaneously reduced. The method yields excellent phosphorus recoveries. It is time saving and adaptable for kilogramm scales.
