The instant powder was prepared with extruded wheat aleurone layer,and the technological formula of extruded wheat aleurone layer instant powder was optimized by orthogonal experiment on the basis of single factor experiment.The results showed that the optimal formula of extruded wheat aleurone layer instant powder was 10.0 g of wheat aleurone layer,5.0 g of xylitol,0.2 g of pectin,0.6 g of whole milk powder,and 2.0 g of maltodextrin.The color of the extruded wheat aleurone layer instant powder was yellow brown with grain aroma,suitable consistency,and good sensory properties.
