摘要
以隆子紫青稞为原料,采用单因素试验和响应面优化试验设计,用分光光度法测定并计算紫青稞色素的提取率。结果表明,紫青稞色素提取工艺条件为乙醇体积分数60%,料液比1∶10(g∶mL),提取温度65.84℃,提取时间1 h,盐酸调节pH值1.0,在此条件下紫青稞色素提取量为1.43 mg/g。
Take Longzi black barley as raw material to extract the pigment through the single-factor experiment and response surface optimization design, and the extraction rate of black barley pigment is determined by spectrophotometry. The results show that the optimal extraction： using volume fraction of ethanol is 60%, the ratio of liquid to material is 1 -1 0 （g：mL） extracted in 65.84 ^ for 1 hour, pH is adjusted to 1.0 by hydrochloric acid. Under this process,the extraction amount of black barley pigment is 1.43 mg/g.
