摘要
以苹果鲜渣为原料,利用嗜酸乳杆菌发酵其浸提液,以活菌数为主要指标,通过单因素试验和响应面分析(RSM)对发酵条件进行优化,确定嗜酸乳杆菌发酵苹果渣浸液的最佳工艺条件为:料水比为1:8～1:10,100℃浸提50～60 min,过滤,添加1.56%酵母粉,1.54%乳清粉,发酵28.14 h,活菌数可达到5.24×109 cfu/ml。
The extract of apple pomace was fermented by Lactobacillus acidophilus,at the target of the number of viable cells.The optimal fermentation conditions were determined by mono-factor experiment and response surface methodology（RSM） analysis.Optimization of fermentation conditions was as follows： the ratio of apple pomace and water was 1：8～1：10,100 ℃ extracted 50～60 min,filtered and added 1.56% dusty yeast,1.54% whey powder,fermented 28.14 h,the number of viable cells reached 5.24×109 cfu/ml.
