摘　　要：以黑果枸杞干果为原料制备黑果枸杞速溶粉。在单因素试验的基础上,采用正交试验优化黑果枸杞花色苷的超声辅助水提工艺,比较热风干燥、超声干燥、冷冻干燥、喷雾干燥对提取物的干燥效果,采用响应面法优化喷雾干燥工艺,并对所得速溶粉的微观形态、粒径大小、溶解时间等进行表征与测量。结果表明:最佳提取工艺为超声功率400 W、料液比1∶20(g/mL)、提取温度20℃、提取时间50 min;喷雾干燥最佳工艺参数为进风温度190℃、进样速度20 mL/min、料液密度1.01 g/mL;喷雾干燥制备的黑果枸杞速溶粉颗粒粒径均一,粒径范围4μm～60μm,平均粒径17μm,平均完全溶解时间为43.4 s,达到行业标准。Lycium ruthenicum Murr.dried fruit was used to prepare instant powder.The extraction process was optimized through orthogonal test.Four kinds of way to dry Lycium ruthenicum Murr.aqueous extract(hot air drying,ultrasonic drying,freeze drying and spray drying)were compared.Spray drying process was optimized by using response surface method.In addition,the micro morphology,particle size,and dissolution time of the obtained instant powder were studied.Ultrasonic extraction results showed that the optimal extraction conditions were as follows:ultrasonic power 400 W,solid-to-solvent ratio 1∶20(g/mL),extraction temperature 20℃,extraction time 50 min.The optimal spray drying technological parameters were 190℃,20 mL/min and 1.01 g/mL for inlet air temperature,inject speed and liquor density,respectively.The particle size of Lycium ruthenicum Murr.powder produced by spray drying was uniform.According to the analysis results of the laser particle size analyzer,the range of size distribution was 4μm-60μm and the mean particle size was 17μm.The average dissolution time of instant powder was 43.4 s,which reached the industry standard.
