乳酸菌发酵甘草溶液工艺优化研究

Study on optimization of fermentation processing of glycyrrhiza solution by lactobacillus

采应用单因素和正交试验优化了乳酸菌发酵甘草溶液工艺参数。试验结果表明,乳酸菌发酵甘草溶液的最佳工艺条件:底物浓度10%、乳酸菌添加量1.5%、葡糖糖添加量3%、大豆蛋白质添加量4%、发酵温度40℃、发酵时间20 h。在该条件下,p H为3.67。

The fermentation processing of glycyrrhiza solution fermented by lactobacillus was optimized by single-factor and orthogonal tests. The results showed that the best processing conditions were as follows: the substrate concentration 10 %, lactobacillus 1.5 %, glucose concentration 3 %, soybean protein 4 %, temperature 40 ℃, time 20 h. The pH was 3.67 under the conditions.
