摘要: exico Abstract: Common beans of the Mayocoba variety were cooked (178min) and evaluated regarding their chemical composition starch digestibility in vitro. Mean physical characteristics grain were: thousand-kernel weight, 443.0 (±0.98)g; length, 12.45mm; width 7.84mm thickness, 6.44mm. Total content bean was 40.24% (dmb). The available 22.87%, whereas resistant accounted for 6.4% retrograded represented 3.3% seed weight. None these values changed with storage time. presented soluble indigestible fraction approximately 8.0% insoluble 36%, which did not change storage. Both simple enzymatic hydrolysis rate index (HI= 36%) indicated a slow starch. HI-based predicted glycemic 39%, all suggested 'slow carbohydrate' feature this bean.  2004 Society Chemical Industry
