摘  要:
采用自行筛选的JAUⅠ (Lactobacillusacidophilus)、JAUⅡ (Lac bulgaricus)、JAUⅢ (Streptococcusdiacetilactis)菌株和JAUⅣ (Str theumophilus)菌株 ,进行多菌株混合发酵鲜牛乳 ,并对发酵过程中和冷藏 2 4h后的酸乳进行双乙酰、乙醛、pH值及滴定酸度测定。结果表明 :4菌株按 1∶1∶1∶1的配比制成发酵乳 ,冷藏后色泽乳白 ,组织状态均匀细腻 ,香气浓郁纯正 ,酸度适口 ,风味最好。pH值达 3 9,滴定酸度达 0 95 %~ 1 0 0 % ,JAUⅠ的菌数超过 1 0 8cfu mL ,各项指标符合酸乳国家标准

摘  要:
Lac. acidophilus (JAUⅠ),Lac.bulgaricus (JAUⅡ),Str.diacetilactis (JAUⅢ) and Str. thermophilus (JAUⅣ) were used as starter culture to produce yogurt.The biacetyl and acetaldehyde contents,pH value, titrable acidity and plate counts were checked and measured. The results showed that the yogurt produced with the 4 strains in the proportion of 1∶1∶1∶1 had the best colour,shape,taste and odour.And pH value was 3.9 .The titrable acidity was 0.95%~1.00% and plate counts of JAUⅠ was over 10 8cfu/mL.All these items are in accordance with national standard.
