低GI枸杞杂粮代餐粉的配方优化及其降血糖作用研究OA北大核心CSTPCD

To explore the optimal formula and hypoglycemic effect of the low glycemic index(GI)barbary wolfberry of coarse grain meal replacement powder,in this study,six grains were used in soybean,mung bean,black bean,oats,Tartary buckwheat and quinoa as the main raw materials,and a low GI barbary wolfberry of coarse grain meal replacement powder was prepared from Ningxia barbary wolf-berry with similar medicine and food.With the sensory score as an indicator,univariate test,Plackett-Burman test,steepest climbing test and Box-Behnken test were used to optimize the low GI barbary wolfberry coarse grain meal replacement powder formula,and the hypogly-cemic effect of low GI barbary wolfberry coarse grain meal replacement powder was evaluated by establishing a type 2 diabetes mellitus mouse model.The results showed that the best formula of barbary wolfberry multigrain meal replacement powder was 15.1％of soybean flour,15.1％of mung bean flour,14％of black bean flour,15.6％of oat flour,12.1％of tartary buckwheat flour,12.1％of quinoa flour,and 16％of barbary wolfberry flour.Low GI barbary wolfberry multigrain meal replacement powder improved the postprandial blood glucose value and improved the basic growth status of mice,but the fasting blood glucose value slowly increased and became overall stable(P＞0.05).
