摘　　要：研究紫苏提取物喷雾干燥工艺条件。在单因素试验基础上,选取提取液相对密度、进风温度、出风温度、入料流量4个因素的3个水平进行正交试验,得到喷雾干燥工艺的优化组合条件。确定最佳工艺条件为:提取液相对密度1.04,进风温度200℃,出风温度80℃,入料流量为15mL/min。The optimum technological conditions of the spray drying process of perilla extract were studied. According to the single factor experiment and the orthogonal test of 4 factors and 3 levels was adopted, and the optimum combination was obtained. The result showed the optimization spray drying process were as followed： the relative density of the extract was 1. 04, inlet air temperature 200 ℃, outlet air temperature 80 ℃, inlet flow rate 15 mL/min.
