Key words: green Vietnamese tea, supercritical carbon dioxide, tea leaves consumer qualities, de-coffeinization
The effect of suggested procedures - circulation of supercritical (SC) carbon dioxide
and periodical decompression in the system «initial raw material - SC-CO2» - of tea
leaves treatment onto the subsequent extraction of target components by hot water.
Some thermodynamic characteristics of SC fluid de-coffeinization process, as applied
to green Vietnamese tea, are investigated.
