超临界CO_2萃取辣椒红色素的研究初探

Preliminary Experiment on Supercritical CO_2 Extraction of Red Pigment from Chilli

简介了超临界CO_2流体的基本特性及国外将该流体应用于萃取分离技术的概况。报道了作者应用超临界CO_2从红辣椒中萃取红色素的研究情况。试验表明,色素和辣味素可以全部萃取出来,并可获得基本分离。

The paper gives introduction to the essential characteristics of supercritical CO2 fluid and its practical applications in extraction and separation processes abroad. Elementary tests for extracting red pigment from red chilli by using supercritical CO2 extraction and separation technique are reported. The test results show that pigment and paprika element can be completely extracted from chilli, and they can be elementarily separated from each other.
