食用玉米黄色素提取方法的选择

Selection of the Metbod in the Extraction of Corn Yellow Pigment

用研磨和浸提法处理玉米淀粉饼渣,回流色素浸提混合液,回收提取液,用不同比例的混合试剂提取以选择最佳方法。结果发现以石油:乙醇=3:2和丙:乙醇=3:2提取液效果最佳,色素产率高,色质好,提取液回收率亦高。

The present paper reports the results of experiments for better methods in extracting corn yellow pigment for food production by pestling and abstracting cornstarch,pefluxing the pigment for the extraction of blend solution, rtcovering the solution and extracting with reagent by the blend solution in differemt-proportion. The results show that the ideal extraction solution is the blend of 3:2 of ligroin and alcochol and that of 3:2 of acetone and alcochol which can result in the high productivty of pigment,good quality of pigment colour and the high recovery of the extraction solution .
