Abstract

Maslinovo ulje oduvijek je bila važna namirnica u svakodnevnoj prehrani mediteranskog stanovništva. Danas je maslinovo ulje postalo sinonim zdravog načina prehrane i modernog življenja. Budući da je maslinovo ulje dobar izvor polifenolnih sastavnica, kojima se pripisuje važna uloga u preventivnom i terapijskom djelovanju ove namirnice na ljudsko zdravlje, cilj ovog rada bio je procijeniti kvalitetu hrvatskih maslinovih ulja obzirom na sadržaj polifenola te odrediti antioksidativnu aktivnost istih. Sadržaj ukupnih polifenola u analiziranim maslinovim uljima određen je spektrofotometrijskom metodom korištenjem Folin-Ciocalteu reagensa, dok je antioksidativna aktivnost procijenjena ABTS testom. Rezultati istraživanja upućuju na iznimnu kvalitetu hrvatskih maslinovih ulja te se analizirana maslinova ulja mogu smatrati dobrim izvorom polifenolnih sastavnica, dok je antioksidativna aktivnost ispitivanih maslinovih ulja u skladu sa sadržajem ovih biološki aktivnih sastavnica.

Abstract (english)

Olive oil has always been an important grocery in the daily nutrition of the mediterranean population. Today olive oil has become a synonym of healthy eating habits and a modern living. Olive oil is a good source of polyphenolic components, which take an important role in the preventive and therapeutic function of this food affecting human health. The purpose of this diploma thesis is to evaluate the quality of Croatian olive oils regarding the proportion of polyphenol and to determine their antioxidant activity. The total content of polyphenols in the analyzed olive oils was determined by spectrophotometric method using Folin-Ciocalteu reagent, while the antioxidant activity was estimated by the ABTS test. The results of the research point to the exceptional quality of Croatian olive oils and that the analyzed olive oils can be considered as a good source of polyphenolic components while the antioxidant activity of the examined olive oils complies with the content of these biologically active constituents.
