【摘要】 以紫玉米芯为原料,通过单因素及正交实验研究紫玉米芯色素提取效率的诸多因素影响,结果表明:各因素对紫玉米芯内色素提取效果的影响程度依次为:浸提液酸度>浸提温度>料液配比>浸提时间。确定了紫玉米芯中色素提取最佳工艺条件为浸提液酸度pH1、浸提温度80℃、料液比1:50、浸泡时间1.5h、提取级数2。更多还原

【Abstract】 Used as raw material, purple corn cob was immersed with hot distilled water and anthocyanins was extracted. The effect of different factors on extraction of pigment with single and multiple factor tests were investigated. The optimum conditions were the acid degree was pH 1, the weight of mixture was 50 times as large as that of the purple corn cob and the pigment was extracted two times at 80 ℃, each step for 1.5 h.更多还原
