腊八豆生产菌株的选育

Breeding of Producing Strains for Laba Beans production

将通过平板分离、筛选和紫外诱变得到的毛霉菌株A2(含高活力中性蛋白酶)和根霉菌株C4(含高活力的α-淀粉酶)按7:3的比例混合接种生产腊八豆,产品的游离氨基酸、氨基态氮和可溶性无盐固型物的含量分别提高了6%、31%和10%,产品的感官品质有显著的提高。

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 ...
