Sažetak
Mushrooms contain many valuable compounds such as fatty acids, carbohydrates, lycopene, lavastatin, trace elements etc. As they are currently valued for biologically active substances, and as high pressure carbon dioxide fluid extraction has been documented as an effective method for preparing bioactive products from plant materials, subcritical and supercritical carbon dioxide extraction of Boletus edulis mushroom was performed. In obtained extracts, the fatty acids were determined. Response surface methodology (RSM) was applied to investigate effect of pressure and extraction time on the extraction yield. The analysis of variance showed that pressure and extraction time had significant effect on extraction yield in both investigated process. The interaction between pressure and extraction time had significant effect only in supercritical extraction process of B. edulis. Higher extraction yields have been obtained by subcritical carbon dioxide, and higher linoleic acid content has been determined in extracts obtained by supercritical carbon dioxide.
