Abstract: A tartary buckwheat compound meal substitute powder rich in rutin was developed with rice, tartary buckwheat, black bean powder, black sesame powder and black rice flour as the main raw materials and malt dextrin, plant fat powder and sugar powder as the auxiliary materials. With sensory score and determination solubility index（DSI） as the index, on the basis of single factor experiments, orthogonal test was used to optimize the compound black buckwheat meal substitute powder best recipe. The results showed that the optimal formula was as followed: raw materials mesh 80 mesh, rice flour 23.4%, tartary buckwheat flour 25%, black soybean flour 5%,black sesame flour 5%, black rice flour 13.3%, plant fat powder 8.3%, maltdextrin 8.3%, and sugar powder11.7%. The product had a sweet smell, rich coarse cereals flavor, uniform color, delicate taste and high solubility.Through the comparison of nutritional composition of plain tartary buckwheat powder and tartary buckwheat compound meal substitute powder, it was found that the fat and protein contents of the meal substitute powder were 6.87% and 11.34% respectively, both higher than plain tartary buckwheat powder, the total amino acid content was 4.6% higher than single tartary buckwheat powder, and the nutritional composition was more reasonable.
