METHOD FOR MACA EXTRACTS WITH HIGH CONTENT OF MACAMIDE

摘要

A method of producing maca extract(Lepidium meyenii) with a high content of macamide by using super critical carbon dioxide extraction is provided to increase extraction efficiency and ensures safety because of using no harmful organic solvent. Lepidium meyenii is extracted by using super critical carbon dioxide extraction by increasing the temperature and pressure of super critical carbon dioxide by a gradient of 0.375deg.C per min from 35deg.C to 80deg.C per and 4.375bar per min from 75bar to 600bar for 2hr.
