摘　　要：优化八月瓜果粉的喷雾干燥制备工艺,并分析其溶解特性。采用单因素试验分别探讨麦芽糊精用量、果浆固形物含量、进风温度、出风温度对果粉得率的影响;通过正交试验对喷雾干燥工艺条件进行优化;检测果粉的流动性、溶解度、溶解时间以研究分析其溶解特性。结果表明:喷雾干燥法制备八月瓜果粉的最佳工艺条件为麦芽糊精用量16%、果浆固形物含量20%、进风温度150℃、出风温度75℃,该条件下果粉得率可达15.52%;制备的八月瓜果粉流动性为9.25cm,溶解度为56.37%,溶解时间为20.2s。Research on optimizing the spray dry preparation technology of Akebia trifoliate fruit powder and analyze its dissolution characteristics.First of all,the effects of dry agent dosage,pulp solids content,inlet air temperature,outlet air temperature on fruit powder yield were discussed by single factor tests.And then the spray drying process conditions were optimized by orthogonal test,and the dissolution characteristics was analyzed by detection of powder fluidity,solubility,dissolution time.The results showed that the optimal preparation conditions of Akebia trifoliate were as followed：malt dextrin dosage 16%,pulp solids content 20%,the inlet air temperature 150 ℃,outlet air temperature 75 ℃.Under these conditions,the powder yield was reached to 15.52%,powder flow 9.25 cm,solubility 56.37%,dissolution time 20.2s.
