【摘要】 通过L9(33)正交试验确定了富硒活性乳酸菌发酵剂的适宜发酵条件,即发酵温度39℃,加硒量5μg/mL,接种量7%。结果表明,研制的发酵剂硒转化率达50.38%,冷藏5 d后发酵活力达0.48,冷藏7 d后活菌数达7.2×108cfu/mL,符合发酵剂的各项质量要求,可作为生产富硒活性乳酸菌功能性乳制品的工作发酵剂。更多还原

【Abstract】 The effects of cultural condition（temperature,Se-concentration,inoculation）were studied by（L-9（3³））?orthogonal test.The result showed that when m（LB）+m（LA）+m（st）=1+1+1,and using restore no fat milk powder,the best fermenting condition were namely fermented temperature 39℃,Se-concentration 5 μg/mL,inoculation amount 7%,Se-enriching ratio 50.38%,the cell population 7.2×10¹⁰ cfu/mL.According with every quality requirement of the fermented pharmaceutical,it could work as the working stock culture which produced the Se-enriching activate Lactobacillus functionality dairy products.更多还原
