摘　　要：以玉米黄粉为原料,采用微波法提取玉米黄色素,研究结果表明,微波提取玉米黄色素的最佳工艺条件为:乙醇浓度为95%,原料目数80目,微波功率为640 W,微波时间为60 s,料液比1∶10,提取率为332.05μg/g。通过正交试验发现,影响提取效果的因素主次顺序为微波功率>微波时间>料液比。采用微波法提取玉米黄色素,可以有效地缩短提取时间,提高提取效率。Microwave was used to extract corn- yellow pigment from corn gluten meal. The optimum extraction conditions of corn- yellow pigment are as follows, ethanol concentration of 95%, mesh size of 80, microwave power of 640 W, irradiation duration of 60 s, solid - liquid ratio of 1： 10, and extraction rate of 332.05μg/g. Through orthogonal experiment, the effects of extraction factors are microwave power〉irradiation duration〉solid-liquid ratio. The extraction of corn- yellow pigment from corn gluten meal by microwave method can effectively shorten the extraction time and improve the efficiency.
