Kinetics of starch digestion in native and modified sweetpotato starches Check for from an orange fleshed cultivar

Starch from orange-fleshed sweet potato cultivar was modified using dual autoclave retrogradation, annealing and lintnering modification treatment and their digestibility properties studied. The rate and extent of digestion were suitably predicted with a first-order kinetic model derived in the course of the study. The starches clearly displayed monophasic digestograms while modified starches were observed to have lower glycemic load and glycemic index when compared to the unmodified starch. This study clearly demonstrates the effect of various starch modification treatments on the digestibility of sweet potato starches and also predicted it digestion kinetics parameters.
