低糖紫薯杂粮复合粉的研制

Development of Low-sugar Compound Grain Powder with Purple Sweet Potato

以紫薯为原料,搭配苦荞、藜麦等杂粮,研制一种低糖紫薯杂粮复合粉。通过单因素和正交试验优化工艺参数。结果表明:适合紫薯的干燥方式为热风干燥。紫薯磨粉时间为3~4 min。紫薯复合杂粮粉配方的最优组合为苦荞添加量5 g、藜麦添加量15 g、甜菊糖添加量0.1%、糖粉添加量1%,紫薯粉添加量80 g。此配方得到的紫薯复合杂粮粉营养丰富、口感适中。

A kind of low-sugar purple potato compound grain powder was developed by combining with purple sweet potato,Tartary buckwheat and quinoa.The process parameters were optimized by single factor and orthogonal experiments.The results showed that hot air drying was the better method for purple sweet potato.The grinding time of purple sweet potato was 3-4 min.The optimal formula of low-sugar purple potato compound grain powder was as follows:5 g Tartary buckwheat,15 g quinoa,0.1%stevia,1%sugar and 80 g purple sweet potato powder.The developed low-sugar purple potato compound grain powder was rich in nutrition and moderate in taste.
