摘　　要：系统研究了超临界流体技术 (SFE)从玉米蛋白粉中提取玉米黄色素的温度、压力、时间、夹带剂等工艺条件 ;该提取法比常规的化学溶剂提取法的得率高 2 .2倍。同时 ,还探讨了玉米黄色素的稳定性 ,结果表明它需要低温、避光保存。The processing conditions such as temperature,pressure,time and cosolvent solution for the extraction of corn-uranidin from corn gluten meal(CGM) by the supercritical fluid extraction were systematically studied. This SFE methode could obtain 2.2 times of yield of corn-uranidin as compared with the solvent extraction.The result of stability study showed that the corn uranidin was sensitive to sunlighr so it should be preserved in dark place at low temperature.
