Abstract
U radu su određena fizikalno-kemijska svojstva (gustoća, viskoznost, indeks loma, pH vrijednost i električna provodnost) prirodnog niskotemperaturnog otapala, pripravljenog od jabučne kiseline, fruktoze, glicerola (oznaka - Ma-Fru-Gly) uz dodatak različitih udjela vode. Pripravljena otapala korištena su za ekstrakciju polifenola iz komine masline te je određen utjecaj vode u NADES-u na učinkovitost ekstrakcije polifenola. Najbolja djelotvornost ekstrakcije dobivena je s najmanjim udjelom vode (20 mas%). Međutim, zbog velike viskoznosti i otežanog miješanja tijekom ekstrakcije, optimalan udio vode u NADES-u iznosi 30 mas%.
Abstract (english)
The physicochemical properties (density, viscosity, refractive index, pH value and electrical conductivity) of a natural low temperature solvent made from malic acid, fructose, glycerol (code - Ma-Fru-Gly) with the addition of different amounts of water are determined in the paper. The prepared solvents were used to extract polyphenols from the olive pomace and the effect of water in NADES on the extraction efficiency of polyphenols was determined. The best extraction efficiency was obtained with the lowest water content (20 %). However, due to the high viscosity and difficult mixing during extraction, the optimum water content of NADES is 30 %.
