超临界萃取技术在辣椒红色素中的应用

The Application of Supercritical Carbon Dioxide Extraction Technology in Paprika Oleoresin

介绍超临界二氧化碳萃取技术提纯辣椒红色素的工作原理及工艺流程。工艺流程通过改变萃取压力、萃取温度、萃取时间和流速等参数确定了最佳工艺条件 ,在此条件下 ,得到的辣椒红色素的色价达 15 0以上 ,且杂质含量符合国家标准。

This article introduces the working principle and technological process of the supercritical carbon dioxide extraction technology in refining paprika oleoresin. Through altering the parameter of the extraction pressure,temperature time and velocity of flow,the optimal technological conditions.Are determined under these conditions, the color value of paprika oleoresin refined can reach above 150, and the content of impurity in paprika oleoresin accords with GB.
