Abstract:By flat separation, screening and mutation with ultraviolet radiation, Mucor strain A2 (containing neutral protease of high acitivity) and Rhizopus strain C4 (containing α-amylase of high activity) were screened. The results showed that, when the mixture of A2 and C4( the ratio of A2 to C4= 7:3) were inoculated to produce laba beans, the contents of free amino, nitrogen of amino acid and soluble substance of the final product were improved 6%, 31% and 10%, respectively, and the sensatory quality of product were also greatly enhanced.
