摘　　要：以青麦仁、玉米、青豆为原料制备复合营养粉,选取进料浓度、进料温度、进料速度为影响因子,以冲调品质为考察指标,在单因素试验基础上,利用响应面试验确定制备鲜食谷物复合营养粉的喷雾干燥最佳工艺条件。结果表明,最佳喷雾干燥工艺为:进料浓度8.38%,进料温度180℃,进料速度643 mL/h,在该工艺条件下制备的复合营养粉的透光率、凝沉性、吸水性、水溶性、水分含量、结块率、黏度分别为80.31%、5.41%、470.26%、37.75%、1.78%、1.85%、5531 mPa·s,感官评分为92.05分,复合营养粉冲调品质最佳。Green wheat berry,corn and green bean were used as raw materials to product multiplicate nutrition powder.The input concentration,feed temperature and feed speed were chosen as influencing factors,and the reconstitutablity of multiplicate powder was selected as the index.Response surface methodology was applied to optimize the spray drying conditions of the fresh grain powder on the basis of the single factor experiment.The results indicated that the optimum condition was determined as followed:input concentration 8.38%,feed temperature 180℃and feed speed 643 mL/h.Under these conditions,the disperal of nutrition powder was the best.Meanwhile the values of light transmittance,retrogradation,hydroscopicity,water solubility,moisture content,caking rate,viscosity and sensory evaluation were 80.31%,5.41%,470.26%,37.75%,1.78%,1.85%,5531 mPa·s and 92.05,respectively.
