Abstract

See full text

Substances producing an undesired odor and taste can be removed from microbial protein materials if these materials are treated with aqueous solutions which contain a phosphate and/or a hydrophilic low molecular weight aliphatic compound which contains at least two functional groups from the series comprising hydroxy, formyl, keto and carboxy. Preferred aliphatic extraction auxiliaries are flavoring acids, sugars and polyols, and phosphates are orthophosphates and diphosphates. The extraction can also be carried out in association with reducing the nucleic acid content of defatted cell aggregates.
