摘要
选取植物乳杆菌、保加利亚乳杆菌以及嗜热链球菌3种益生菌,对沙芥进行发酵处理,以发酵活菌数和酸度为参考指标,通过单因素试验以及正交试验确定复合菌的配比为植物乳杆菌∶嗜热链球菌∶保加利亚乳杆菌=4∶4∶3(质量比),最佳发酵工艺:发酵温度33℃、发酵时间14 h、菌种接种量4%;基于此发酵工艺条件,测得沙芥发酵饮料所含活菌数达6.03×10^(8)CFU/mL。
Three probiotic strains,including Lactobacillus plantarum,Lactobacillus bulgaricus,and Streptococcus thermophilus,were selected to ferment Pugionium cornutum.With the viable bacteria count and acidity as the reference indicators,the composite proportion of the strains was determined through single-factor and orthogonal experiments,resulting in L.plantarum∶S.thermophilus∶L.bulgaricus=4∶4∶3(mass ratio).The optimal fermentation process was determined as follows:fermentation temperature of 33℃,fermentation time of 14 hours,and an initial inoculum of 4%of the total volume.Under these conditions,the P.cornutum fermented beverage was found to contain viable bacteria count of 6.03×10^(8)CFU/mL.
