摘　　要：开发低血糖生成指数(Glycemic Index,GI)方便米饭以满足糖尿病和超重/肥胖人群的饮食需求。低GI方便米饭以大米为主要原料,同时添加白芸豆α-淀粉酶抑制剂(α-AI)、魔芋粉、抗性糊精和单,双甘油脂肪酸酯并采用双螺杆挤压法进行制备。以感官评价和体外消化实验为评价指标,通过单因素和正交实验确定最优配方为α-AI添加量1.00%、魔芋粉添加量4%、抗性糊精添加量8%、单,双甘油脂肪酸酯添加量0.3%。该条件下方便米饭的葡萄糖释放率为36.72%,感官评分为85.38分。产品的可利用碳水化合物含量为74.6%,膳食纤维含量高达5.94%,复水时间仅需11.33min。通过人体GI值测试,该方便米饭的GI值为32.18,属于低GI食品,具有稳定餐后血糖波动的作用,有利于胰岛素调节和延缓饥饿,是超重/肥胖、糖尿病人群的理想主食。To develop low glycemic index(GI)instant rice to meet the dietary needs of diabetes and overweight/obese people.Low GI instant rice was used rise as the main raw material while added white kidney beanα-Amylase inhibitors(α-AI),konjac flour,resistant dextrin,and mono-diglycerol fatty acid esters,which were prepared by twin screw extrusion method.Sensory evaluation and in vitro digestion experiments were used as evaluation indicators,and the optimal formula was determined through single factor and orthogonal experiments as follows:1.00%α-AI,4%konjac flour,8%resistant dextrin,and 0.3%mono-diglycerol fatty acid ester.In the condition,instant rice achieved the lowest glucose release rate with 36.72%.And The sensory scores,available carbohydrate content,dietary fiber content,and rehydration time of instant rice were 85.38,74.6%5.94%,and 11.33 minutes.According to the human body GI value test,the GI value of instant rice in this formula was 32.18,which belongs to low GI food.Instant rice can reduce the fluctuation of blood sugar after meals,which help stabilize insulin and delay hunger,which is an ideal staple food for people with overweight/obesity and diabetes.
