Abstract

A mucilaginous polysaccharide was isolated from black gram under different processing conditions. The trichloroacetic acid (TCA) extracted and acetone precipitated polysaccharides contained L-rhamnose, Larabinose, o-xylose and o-galactose along with o-galacturonic acid (12-13%). The polysaccharide preparations showed considerable changes in galactose and rhamnose contents" during processing. The a-galactosidase activity as well as the viscosity increased by 25-30% after fermentation. Rheological constants such as yield stress and consistency index showed considerable changes but flow behaviour index did not show much change. The zero shear intrinsic viscosity or consistency index appeared to be related to the galactose content of the polysaccharide.
