| 摘 要： | 使用乳酸菌发酵米糠,以菌种、菌种添加量、发酵温度、发酵时间为单因素研究其对米糠发酵液中γ-氨基丁酸(GABA)含量的影响,在最适条件下,采用混料设计法,使用混合乳酸菌发酵米糠,以发酵液中GABA含量为指标,确定乳酸菌发酵米糠的最优条件为:在混合菌种嗜热链球菌S1添加量为1.55%,保加利亚乳杆菌L1添加量为1.45%,50℃下发酵米糠14h,发酵液中GABA含量最高,为287.975mg/100g。

| Abstract: | Lactobacillus were used to ferment rice bran. Strains,adding amount of strains,fermentation temperature and fermentation time were used as single factor and their influence on the production of GABA of the fermented rice bran were researched.The mixture design method were used to determine the optimum conditions and mixed lactobacillus were used to fermente rice bran with the number of GABA content for index,lactobacillus ferments rice bran optimal conditions were investigated,the result showed:in the mixed bacteria streptococcus thermophilus cultured S1 add content was 1.55%,Bulgaria lactobacillus L1 add content was 1.45%,50℃ fermented rice bran 14h,the number of GABA content was highest for 287.975mg/100g. |
