The effects of soybean saponin on tryptic and chymotryptic hydrolyses of whey proteins were evaluated. Beta-lactoglobulin and alpha-lactalbumin became more sensitive to both trypsin and chymotrypsin by interacting with saponin in contrast to serum albumin. Soybean saponin was shown to have different...
