  1. *AUC- area under the starch hydrolysis curve HI- hydrolysis index GI- glycemic index C∞—theoretical value of digested starch at the equilibrium point of starch hydrolysis k – rate constant for the starch hydrolysis reaction. All values are expressed as the mean of duplicate samples and the standard deviation with p < 0.05. Values with different letters in the same column are significantly different at p < 0.05.
