Abstract

A method for reprocessing a phase substantially consisting of steryl glycoside/fatty acid alkyl ester/water agglomerates, which was formed when fatty acid alkyl ester generated by transesterification of vegetable oils or animal fats was washed with water, wherein the water content is evaporated by heating the phase and subsequently the steryl glycosides are split into their sterol and sugar fractions in the presence of an acid catalyst.
