摘要
以市售栀子黄色素为原料，比较系统地探讨了超临界状态下萃取压力、温度、时间、ＣＯ２ 流量、夹带剂对栀子黄色素ＯＤ值比率的影响。结果表明：高温、高压、添加夹带剂的条件下有利于降低栀子黄色素的ＯＤ值比率，达到精制的目的。
Gardenia yellow pigment that was bought from the market was taken as experimental material in the paper. The influence of extracting pressure, temperature,time,CO 2 flow,modifier on the OD ratio of the gardenia yellow pigment was first studied systematically under supercritical condition. The results showed that the condition of high pressure,high temperature and adding modifier is suitable to decrease OD ratio and achieve the goal of purifying gardenia yellow pigment.
