Abstract
Diljem Mediterana provode se procesi obrade maslina uslijed kojih nastaje komina masline koja predstavlja čvrsti otpad. Ona sadrži vrijedne bioaktivne komponente koje nalaze primjenu u brojnim industrijama kao što su prehrambena, farmaceutska i kozmetička. Međutim, u komini masline također nalazimo veću koncentraciju lipida, organskih kiselina i fenolnih spojeva koji tijekom vremena svojim fitotoksičnim djelovanjem negativno utječu na okoliš. Kao što su pokazala prethodna istraživanja, komina masline bogata je snažnim antioksidansima upravo zbog visokog sadržaja fenolnih spojeva. Pokazano je da fenolni spojevi pozitivno utječu na ljudsko zdravlje zahvaljujući njihovoj sposobnosti vezanja slobodnih radikala u organizmu. Kao potencijalno rješenje poboljšanja učinkovitosti ekstrakcije nameću se niskotemperaturna eutektička otapala. Nova, dizajnirana eutektička otapala pokazala su veću učinkovitost u ekstrakciji biaktivnih komponenata u odnosu na konvencionalna otapala ili vodu, dok istodobno zadovoljavaju načela „zelene kemije“ primjenom netoksičnih, nehlapljivih, sigurnih i obnovljivih otapala. U ovom radu ispitana je mogućnost poboljšanja učinkovitosti ekstrakcije fenolnih spojeva iz komine masline koristeći prirodna eutektička otapala. Prikazani su rezultati ekstrakcije fenolnih spojeva iz komine masline, definiran je najučinkovitiji način miješanja i određeno je optimalno vrijeme trajanja ekstrakcije.
Abstract (english)
Olive processing being done across the Mediterranean region results in generating olive cake which is a solid waste. It contains valuable bioactive components used in various industries, such as food, pharmaceutical and cosmetic industry. However, the olive cake also contains high concentrations of lipids, organic acids and phenolic compounds which impact the environment over time because of their phytotoxicity. As previous studies have shown, olive cake contains powerful antioxidants due to its high phenolic content. Reasearch shows that phenolic compounds have positive effects on human health as a result of their ability to capture free radicals in the organism. Low-temperature deep eutectic solvents (DES) application is imposed as one of potential solutions for improving the efficiency of extraction. New, designed eutectic solvents have shown greater efficiency in extracting bioactive components compared to conventional solvents or water, while upholding the principles of green chemistry of using non-toxic, non-volatile, safe and renewable solvents. In this study the improvement of efficiency of the extraction process of phenolic compounds from olive cake using natural eutectic solvent has been investigated. This study shows results of phenols extraction process from olive cake, the most effective stirring and optimal extraction time.
