【摘要】 以藜麦为主要原料,以脱脂奶粉、绿茶粉和木糖醇为辅料制备复合代餐粉,通过单因素试验和正交试验优化藜麦粉挤压膨化工艺参数和藜麦绿茶营养代餐粉配方,并研究该代餐粉的冲调性和营养成分.结果表明:藜麦粉最优的挤压膨化工艺参数为物料水分含量18%,挤压温度190℃,螺杆转速260 r/min;藜麦绿茶营养代餐粉的最优配方为藜麦粉添加量51%、脱脂奶粉添加量24%、绿茶粉添加量10%和木糖醇添加量15%;藜麦绿茶营养代餐粉的最佳冲调水温和料液比分别为80℃和1∶6,此时代餐粉的结块率为3.72%,冲调稳定性指数为3.91%;制备的藜麦绿茶营养代餐粉是一款营养丰富、口感好、风味佳的代餐产品.更多还原

【Abstract】 With quinoa as the main raw material,skim milk powder,green tea powder and xylitol as auxiliary materials,compound meal replacement powder was prepared. The extrusion parameters of quinoa powder and the formula of quinoa green tea nutritional meal replacement powder were optimized by single factor test and orthogonal test,and the preparation and nutritional composition of quinoa green tea nutritional meal replacement powder were studied. The results showed that the optimal extrusion parameters of quinoa flour were 18%moisture content,190 ℃ extrusion temperature and 260 r/min screw speed. The optimal formula of quinoa green tea nutritious meal replacement powder was 51% quinoa powder,24% skim milk powder,10% green tea powder and 15% xylitol. The best water temperature of quinoa green tea nutritious meal replacement powder was 80 ℃,the best ratio of flavor-liquid was 1∶6,the agglomeration rate of meal powder was 3.72%,and the stability index of meal replacement was 3. 91%. The prepared quinoa green tea nutritious meal replacement powder was a nutritious and delicious meal replacement product.更多还原
