Digestibility index and factors affecting rate of starch digestion in vitro in conventional food preparation.
Nahrung. 1999 Feb; 43(1):42-7.N

Abstract

The rate of starch hydrolysis in ten cereal-based food preparations was studied using an in vitro dialysis system. The foods were incubated with human saliva and porcine pancreatin. The sugars released after 3 h digestion were expressed as digestibility index (DI), the percentage starch digested was determined and correlated with the degree of gelatinization (DG). Granule morphology was also investigated and related with starch availability for hydrolysis. Significant differences were observed in the in vitro starch digestibility of the 10 foods (P < 0.05). The DI ranged from 53 for chapathi to 78 for rice flakes. DI was inversely related to the protein (r = -0.79, P < 0.01), fat (r = -0.63, P < 0.05) and energy (r = -0.61, P < 0.01). Percent starch digested was inversely related to the insoluble (r = -0.49, P < 0.05) and total dietary fiber (r = -0.63, P < 0.01) content of the foods. The SEM results provided a better understanding of granular morphology on cooking and the effect of protein on limiting DG. The results suggest that carbohydrate foods of potential use in the therapeutic diets may be identified by their in vitro digestion characteristics.
