Abstract:Dandelion，soybean and black bean were used as raw materials to develop dandelion small tofo special electric grinding machine，and standardization，industrialization research and nutritional composition analysis were carried out.Sensory evaluation，single factor experiment and orthogonal test were used to optimize the processing conditions and formula of dandelion small tofo.The results showed that the dandelion was blanched in boiling water at 100℃for 105 s and ground into soybean foam according to the ratio of bean to water of 3∶1；the ratio of two kinds of soybean foam （soybean∶black bean）was 3∶2，the ratio of soybean foam to dandelion foam was 3∶1；the ratio of added water to solid matter（dandelion+bean foam）was 1∶2；the product energy was 321 kJ/100 g，the protein content was 7.3 g/100 g，the fat content was 3.5 g/100 g，the carbohydrate content was 0.6 g/100 g，and the dietary fiber was 7.2 g/100 g，the content of flavonoids was 0.012 g/100 g respectively.The products produced by this process and formula were fragrant，delicate and green in color，which lays a foundation for the industrialization development and promotion of wild dandelion small tofo series products.
