Abstract

This work aims to evaluate starch digestion in whole sorghum grains. Nine sorghum cultivars were sampled from the Sahara of Algeria. The structural characteristics of sorghum grains were measured. Total starch (TS) varied between 67.67% and 74.82%, digestible starch (DS) between 64.34% and 69.70%, and resistant starch (RS) ranged from 2.55% to 7.98%. The kinetic of starch digestion displayed first-order model. For all sorghum cultivars, starch were digested with different extents, DS at infinite time (D ∞) ranged from 52.58 to 102.13 g/100 g dry starch, while the hydrolysis index (HI) ranged from 41.55% to 76.93% and high average glycemic index (GIavg) ranged from 65.97 to 94.14. The results showed that there are differences in grain quality of Algerian sorghum cultivars. The starch fractions have acceptable nutritional value with good in vitro digestibility characteristics suitable for human health and nutrition.

摘要

本研究旨在评估整粒高粱中的淀粉消化情况。从阿尔及利亚撒哈拉地区采集了 9 个高粱品种。测量了高粱籽粒的结构特征。总淀粉（TS）含量在 67.67%至 74.82%之间，可消化淀粉（DS）含量在 64.34%至 69.70%之间，抗性淀粉（RS）含量在 2.55%至 7.98%之间。淀粉消化的动力学呈一级模型。对于所有高粱品种，淀粉的消化程度不同，无限时间时的 DS（D∞）范围为 52.58 至 102.13 g/100 g 干淀粉，而水解指数（HI）范围为 41.55%至 76.93%，平均高血糖指数（GIavg）范围为 65.97 至 94.14。结果表明，阿尔及利亚高粱品种的籽粒品质存在差异。淀粉各组分具有可接受的营养价值，体外消化特性良好，适合人类健康和营养。
