EXTRACTION OF GOSSYPOL AND OLIGOSACCHARIDES FROM OILSEED MEALS

Abstract

ABSTRACT Removal of gossypol from cottonseed meal and fermentable sugars from soybean meal by butanol‐HCl solution was tested. Acidic butanol treatment yields low gossypol cottonseed protein concentrates and low oligosaccharides soy protein concentrates, respectively. This procedure does not appreciably alter proteins, as it is shown by the comparison of electrophoretic patterns of albumins and globulins extracted from meal and corresponding protein concentrates.
