| 摘 要： | 以橘皮为原料,从影响橘皮黄色素提取率的主要因素:提取温度、时间和溶剂出发,通过设计正交实验对黄色素的制备工艺进行了优化,并对制备后橘皮黄色素的性质进行了初步研究。研究表明,体积分数为70%的乙醇以1∶8(g/mL)的料液比在温度60℃下浸提5h,得到的黄色素浓度最高,在370nm处的吸光度为1.372,且具有很好的水溶性,对光和热的耐受性强,受pH值变化的影响小。

| Abstract: | Using orange peel as a raw material,a yellow pigment was extracted by the method of alcohol soak. The optimal technology conditions were obtained by orthogonal experiment as followed:extracting solution of 70% ethanol,extracting duration of 5 h,extracting temperature of 60 ℃,solution ratio of 1∶8(g/mL). Meanwhile,the property of yellow pigment was studied. The result indicated that it has good light resistance,heat resist ing property and is ethanol soluble. And it has little effected on stability under pH. |
