中文摘要: 以红枣发酵液的乳酸含量和活菌数为指标,选择嗜酸乳杆菌(NCFM)、干酪乳杆菌(D400)、植物乳杆菌(121)和嗜热链球菌(St)作为发酵菌种,利用混料设计法优化菌种配比。建立了各菌种配比与发酵液活菌数和乳酸含量的数学回归模型,并对此进行分析和预测,得出各菌种最佳体积比为:干酪乳杆菌(D400)∶嗜酸乳杆菌(NCFM)∶植物乳杆菌(121)=1∶1∶2,此时活菌数为1.81×109CFU/mL,乳酸含量为6.31 g/L。

Abstract:Viable count and lactic acid content was chosed as indicators,then selected Lactobacillus acidophilus(NCFM),Lactobacillus casei(D400),lactobacillus plantarum(121)and Streptococcus thermophilus (St),Mix design optimization was used to determine the optimal lactobacillus proportion in Jujube Juice fermentation.The regression mathematicalmodels ofthe factors on viable countand lactic acid contents were built. The optimum volume ratio were D400∶NCFM∶121=1∶1∶2,and the viable countatthis condition was 1.81× 109CFU/mL,lactic acid contentwas 6.31 g/L.
