超临界CO2萃取辣椒副产物中的辣椒碱

Extraction of Capsaicin from Pepper By-Product by Supercritical CO2

本试验以辣椒副产物(脱色辣椒粉)为原料,采用超临界流体萃取技术系统开展了辣椒综合开发利用的工艺研究。通过实验研究得出了超临界流体CO2萃取辣椒碱的适宜工艺方法和工艺条件,得出超临界流体萃取辣椒碱的提取纯度及得率。

In this experiment, the pepper by-product (decolorized paprika) was used as raw material, and the technology of comprehensive development and utilization of pepper was systematically carried out by supercritical fluid extraction technology. Through experimental research, the suitable process and process conditions for supercritical fluid CO2 extraction of capsaicin were obtained. The effects of extraction parameters such as extraction pressure, extraction temperature, separation pressure and separation temperature on the content and yield of capsaicin were studied. The orthogonal experimental results of capsaicin content, capsaicin yield and comprehensive index were carried out. The analysis shows the suitable process and process conditions for supercritical fluid extraction of capsaicin.
