摘要
研究了浸提剂、乙醇体积分数、料液比、浸提温度、浸提时间等因素对黑豆皮色素提取的影响.结果表明,黑豆皮色素的最佳提取工艺为:体积分数为50%的乙醇与体积分数为0.8%的盐酸按1∶2混合作浸提剂,以料液比1∶20,于70℃恒温浸提60 min,黑豆皮色素的提取率较高.
Effect of extraction solution,ethanol concentration,ratio of solid to liquid,extraction temperature and time on extraction of pigment from black soybean skin were studied,and optimum extraction technologies of black soybean skin pigment were determined by orthogonal experiment method.The results showed that extraction solution was 50% ethanol-0.8% HCl（1∶2）,ratio of solid to liquid was 1∶20,extraction temperature was 70 ℃,and time was 60 min.
