Abstract
Cilj ove doktorske disertacije bio je ispitivanje potencijalne primene mikrotalasnog zračenja na povećanje prinosa ulja semena divljeg nara (Punica granatum L.) nakon ekstrakcije i ispitivanje biološke aktivnosti dobijenog ulja. Ispitan je uticaj operativnih parametara (snage i vremena) mikrotalasnog zračenja na prinos i sastav ulja dobijenog natkritičnom ekstrakcijom (NKE) sa ugljenik(IV)–oksidom (CO2) i ekstrakcijom heksanom u aparaturi po Soxhlet–u (SE). Seme divljeg nara je odabrano kao sirovina za ispitivanje zbog svoje vredne biološke aktivnosti (jakog antioksidativnog i potencijalnog citotoksičnog dejstva)...
The aim of this PhD thesis was investigation of the potential application of microwave radiation, in order to increase the yield of wild growing pomegranate seed oil (Punica granatum L.) after exctraction and analysis of biological activity of the obtained oil. The influence of operating parameters (power and time) of microwave irradiation on yield and composition of the oil obtained by supercritical fluid extraction with carbon dioxide (SFE) and extraction with hexane in the Soxhlet apparatus (SE) was examined. Wild growing pomegranate seed was used as raw material for experiments, due to its valuable biological activity (strong antioxidant and potential cytotoxic effect)...
