Abstract With starch hydrolysis rate as index,the inhibiting effect of α-amylase inhibitor( α-AI) from white kidney beans on starch hydrolysis was investigated.The effect of α-AI on the commercially available instant porridge with high different glycemic index（GI） was analyzed. The results show that with the increasing of αAI addition in rice porridge from 0% to 5%, the GI of rice porridge is continuously decreased from 86.63 to 32.03. The GIs of three instant porridges of oat porridge, barley porridge and lotus seed porridge are all decreased lower than 55 for adding 3% α-AI, which indicates that these types of porridge belong to low GI food.
