- Abstract
The effect of heat treatment and dietary fiber from whole and dehulled black bean (Phaseolus vulgaris) seeds on digestibility of various starches by bovine, porcine and human pancreatic α‐amylases was studied. Corn, rice, wheat and black bean starch digestibility increased after heating. The degree of hydrolysis of black bean starch ranged between 56 and 83% of the values obtained for cereal starches depending on the enzyme used. Enzyme activity was: human‐ > porcine > bovine regardless of the substrate employed. Dietary fiber decreased starch digestibility by porcine enzyme. This effect was more marked when whole grain fiber was used. Black bean and rice starch digestibility by human amylase was not affected by fiber,... (More)

The degree of hydrolysis of black bean starch ranged between 56 and 83% of the values obtained for cereal starches depending on the enzyme used. Enzyme activity was: human‐ > porcine > bovine regardless of the substrate employed. Dietary fiber decreased starch digestibility by porcine enzyme. This effect was more marked when whole grain fiber was used. Black bean and rice starch digestibility by human amylase was not affected by fiber, while corn and wheat starch hydrolysis was slightly inhibited. The use of the human enzyme is recomended for in vitro amylolysis assays. Attention is called on the difficulties of extrapolating results obtained with animal enzymes to humans.
