摘　　要：对香菇提取液进行喷雾干燥,可得富含香菇营养和鲜味成分的香菇精粉。通过对影响喷雾干燥效果的因素进行正交试验,得到了最佳的工艺参数,即离心式雾化器的空气压力为0.40～0.45MPa;物料的浓度为BX30(提取液BX20+糊精10%);进风温度180～190℃,物料的流速15～20mL/min。产品得率达到90%以上,水分低于4%。制得的香菇精粉呈浅棕色,香味浓郁,含有丰富的游离氨基酸和5-'鸟苷酸,是很好的调味基料。Lentinus edode extract fluid was spray-dried to prepare the powder of Lentinus edodes which is rich in nutrients and flavor substances. Afected factors of spray-drying were studied, and the optimum technological parameters were obtained as following： When air pressure of Centrifugal atomizer was 0.40 - 0. 45 MPa,the relative concentration of extract fluid should be Bx 30（extract Bx 20 ＋ dextrin 10%）. Entering air temperature was 180 - 190 ℃ and material flow rate was 15 20 mL/min. Yield of powder of Lentinus edodes was above 90% . The moisture content of powder was below 4%. The powder of Lentinus edodes is pale brown, fragrant , rich in free amino acids and 5＇-guanosine monophosphate and good as seasoning.
