摘要
采用浸提法提取超级黑糯玉米芯中的色素,考察不同溶剂、乙醇体积分数、浸提温度、浸提时间和液料比等因素对浸提效果的影响。通过单因素试验和正交试验,确定超级黑糯玉米芯色素的最佳提取工艺条件为:以95%乙醇与0.1mol/LHCl混合提取剂,料液比1:20(m:v),在50℃下浸提60min,在此条件下色素提取率达93.18%,产率达15.62%。
In order to ascertain the optimal conditions of extracting pigment from super black glutinous corncob,solvent,alcohol concentration,extraction temperature,extraction time,and liquid to material ratio were studied.Then the optimal conditions were determined by an orthogonal experiment based on single factor test.Results：The obtained optimum extraction conditions are the mixture of 95% ethanol with 0.1 mol/L HCl,temperature 50 ℃,extraction time 60 min,liquid to material ratio 20：1（v：m）,extraction rate of the pigment 93.18% and exaction yield of the pigment 15.62%.
