STUDYING THE PRODUCTION AND ANALYSIS OF CHLOROGENIC ACIDS-RICH EXTRACTS FROM GREEN COFFEE BEANS AND COFFEE BY-PRODUCTS

Abstract

Extraction and purification of 10kg/lot scaled-processses to manufacture the chlorogenic acids-rich extracts
(CGAE) higher than 50% from green coffee beans, coffee leaves and husks were built for herbal material
use. For the materials and CGAE products, the HPLC-DAD technique was used to quantify the total
chlorogenic acids (CGAs). Quantitative analysis showed that the CGAs content of the green coffee beans,
coffee leaves, coffee husk were corresopingly in the range of 7.03 - 11.21%, 0.54 - 0.82%, 1.53 - 1.85% and
that of all the CGAEs higher than 50%.
