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.
