Effects of fermentation time, material thickness, temperature, solid-liquid ratio on the protein content, protease activity, and antioxidant ability of tartary buckwheat were studied with the solid-state fermentation by Eurotium cirstatum. The results showed that when fermentation time, material thickness, temperature, solid-liquid ratio was 4 d, 1.0 cm, 24 ℃ and 1∶0.6 (g∶ml), respectively, the content of total protein in tartary buckwheat was the highest. Among them, the content of albumin was higher than that of unfermented tartary buckwhe...
