Constitution of leguminous seeds. The effect of some physico‐chemical factors on the yield of proteins isolated from Phaseolus beans

Abstract

AbstractThe yields of acid‐soluble proteins isolated from white kidney beans (Phaseolus vulgaris), navy beans (P. vulgaris) and baby lima beans (P. lunatus) were determined under different conditions of extraction. Highest yields of protein material were obtained when malic acid solutions [0.4M (pH 3.5) white kidney bean and navy bean; 0.05M (pH 3.5) baby lima bean] were used and under the following conditions: shaking time 20‐30 min; extraction temperature 40‐45°C; particle size 0.50‐1.00 mm.
