中文摘要: 建立活性乳酸菌酸奶粉加工技术参数。新鲜牛乳经过发酵后得出最佳乳酸菌活性产品,首先使用单因素试验法选择最佳酸奶粉喷雾干燥参数,再采用响应面法对所得试验结果进行系统的优化,从而选定最佳发酵工艺条件如下:进风温度149.2℃、出风温度70.5℃、干物质含量35.8%、进料流量10.6 mL/min。该工艺条件下生产的产品活菌数较高,感官品质优良。
Abstract:The processing technology parameters of lactic acid bacteria yoghurt powder was established in this study.The optimum fermentation conditions were determined by the method of response surface method,and the optimum fermentation conditions were selected by the method of single factor experiment.The optimum fermentation conditions were selected by the method of response surface method.As followed:into the air temperature of 149.2℃,the outlet temperature of 70.5℃,dry matter content of 35.8%,feed flow 10.6 mL/min.Under the conditions of the process,the number of viable products is high and the sensory quality is excellent.
