Abstract

Linseed mucilage was isolated by aqueous extraction and precipitation with acetone or ethanol. The viscosity of aqueous dispersions of the mucilage was studied as a function of concn., pH and temp. At 0.5-0.6% levels, guar gum dispersions had nearly twice the viscosity of linseed polysaccharide; max. viscosity was found at pH 5-7, and the decrease was greater at acidic pH. Viscosity decreased considerably at higher temp. Chlorides of Na and K decreased the viscosity by 10%, Ca by 20% and ferric salts by 50%. KI decreased the viscosity by 40%. Carbonates of Ca and Mg increased the viscosity by 10-12%. Of the organic salts sodium acetate, sodium potassium tartrate, and sodium citrate, and potassium citrate decreased the viscosity by a similar amount. Ferric citrate reduced viscosity by 50%. The mucilage at about 1% concn. stabilized the foam formed by surface active proteins of peanut and sesame flours against thermal disruption.
