Key words: grape seeds, supercritical fluid extraction, carbon dioxide, grape seed oil, wax, biologically active substances
The effect of carbon dioxide pressure, temperature and time on the efficiency of
supercritical fluid extraction of fatty oil and wax from grape seeds was studied. The
optimal conditions for the production of oil and wax from grape seeds using
supercritical carbon dioxide as an effective extract ant, instead of traditionally used
organic solvents. Organoleptic and physico-chemical parameters of extracts were
determined; fatty acid composition of grape oil was studied by chromato-mass
spectrometry. It is shown that two natural valuable products can be obtained from
grape seeds by supercritical fluid extraction with carbon dioxide: grape seed oil and
wax, which are widely in demand in the food, pharmaceutical industry and cosmetology.
