摘　　要：使用超临界CO2法从水解玉米蛋白粉中提取玉米黄色素。通过单因素实验和正交实验优化了超临界CO2萃取玉米黄色素的工艺条件,并通过HPLC检测提取物中玉米黄素和叶黄素的含量。结果表明:超临界CO2提取玉米黄色素的最佳条件为:萃取时间2 h,CO2流速35 kg/h,萃取压力30 MPa,萃取温度45℃,夹带剂15%无水乙醇,此时玉米黄色素产量为210.97μg/g。Maize yellow pigment was extracted from hydrolyzed corn gluten ： （ SFC-CO2 ） in yellow pigment, this paper. To optimize supercritical fluid extraction （ SFE meal using supercritical carbon dioxide ） conditions for the extraction of maize single factor and orthogonal designed experiments were conducted. The amounts of lutein and zeaxanthin were determined by HPLC. A maximum of 210.97 μg/gof maize yellow pigment was extracted by SC-CO2 in 2.0 h （ CO2 flow rate = 35 kg/h ） at 45℃ and 30 MPa, with the addition of 15% ethanol as a cosolvent.
