چکیده انگلیسی
The effect of processing on starch digestibility, predicted glycemic indices (pGI), polyphenol contents and alpha amylase inhibitory properties of beans (Phaseolis vulgaris) and breadfruit (Treculia africana) was studied. Total starch ranged from 4.3 to 68.3 g/100 g, digestible starch ranged from 4.3 to 59.2 to 65.7 g/100 g for the raw and processed legumes; Resistance starch was not detected in most of the legumes except in fried breadfruit and the starches in both the raw and processed breadfruit were more rapidly digested than those from raw and cooked beans. Raw and processed breadfruit had higher hydrolysis curves than raw and processed beans with the amylolysis level in raw breadfruit close to that of white bread. Raw beans had a low glycemic index (GI); boiled beans and breadfruit had intermediate glycemic indices respectively while raw and fried breadfruit had high glycemic indices. Aqueous extracts of the food samples had weak α-amylase inhibition compared to acarbose. The raw and processed legumes contained considerable amounts of dietary phenols and flavonoids. The significant correlation (r = 0.626) between α-amylase inhibitory actions of the legumes versus their total phenolic contents suggests the contribution of the phenolic compounds in these legumes to their α-amylase inhibitory properties.
