摘　　要：[目的]研究喷雾干燥制备戊糖乳杆菌LEPM818细菌素的最佳条件。[方法]以戊糖乳杆菌LEPM818所产细菌素为材料,分别对喷雾干燥制备细菌素过程中的辅料比、进口温度、蠕动泵值等因素进行了优化研究。[结果]最佳的喷雾干燥条件为辅料比10%,进口温度170℃,出口温度130℃,风机值80 m3/min,蠕动泵值1 200 ml/h。在此基础上进行喷雾干燥,产品得率为96.27%,总活力可达5.78×103AU。[结论]该研究为喷雾干燥制备细菌素的进一步应用研究提供了理论依据。[Objective] To study the best spray drying method for preparing Lactobacillus pentosasus LEPM818.[Method] With Lactobacillus pentosasus LEPM818 as materials,the factors of solid-liquid ratio,inlet air temperature and feed flow rate were optimized.[Result] The optimal conditions for spray drying were as follows： solid-liquid ratio 10%,inlet air temperature 170 ℃,outlet air temperature 130 ℃,air-blower 80 m3/min and feed flow rate 1 200 ml/h.On the basis of spray drying,production was easy to operate with a yield of 96.27%,and the maximum total activity was up to 5.78×103 AU.[Conclusion] The study provided theoretical basis for the preparation of bacteriocin by spray drying.
