摘要
以总黄酮、超氧化物歧化酶(SOD)含量为指标,考察了离心喷雾干燥制备青稞麦绿素粉体的影响因素,并确定了最佳工艺条件:进风温度为230℃,出风温度为100℃,离心雾化器转速为13800r/min,进料速度为70.6mL/min,料液比为1:4。所制得的麦绿素总黄酮含量为2.58mg/g,SOD含量为54.93u/g。
The effect factors of preparing highland barley green by centrifugal spray drying processing were studied in detail according to contents of flavonoids and superoxide dismutase（SOD）.The optimal spray drying processing conditions were determined as follows：the air temperature at the inlet was 230℃,and at the exit was 100℃,the rotating speed of centrifugal atomizer was 13800r/min,liquid feed rate was 70.6mL/min,and the ratio of material to water was 1：4.The content of flavonoids was 2.58mg/g and SOD was 54.93u/g.
