摘　　要：以柿子多糖酶解液为原料,采用正交设计对柿子多糖喷雾干燥进行工艺条件的优化,分别考查最佳进风温度、进风风量、进料流量、助干剂添加量对柿子多糖喷雾干燥制粉的影响。在单因素试验的基础上,采用得粉率和溶解时间为评价指标,确定了喷雾干燥助干剂效果最佳的为麦芽糊精,最佳工艺为进风温度150℃,进风风量95%,进料流量17 mL/min,助干剂添加量40%,在此条件下喷雾干燥得到柿子多糖得粉率为33.64%,溶解时间为14.42 s。Using enzymatic hydrolysate of persimmon polysaccharide as raw material,orthogonal design was used to optimize the process conditions of persimmon polysaccharide spray drying,and the effects of optimal inlet air temperature,inlet air volume,feed flow rate and additive amount of drying aid on the powder preparation of persimmon polysaccharide spray drying were investigated.On the basis of single factor test,maltodextrin was determined to be the best spray drying aid and the optimal process was as follows:The powder yield of persimmon polysaccharide was 33.64%and the dissolution time was 14.42 s under the conditions of 150℃,95%inlet air volume,17 mL/min feed flow and 40%drying aid.
