Determination of sterols in olive oils from Dubrovnik area : diploma thesis

Maslinovo ulje danas je postalo sinonim zdravog načina prehrane i modernog življenja. Sve je više znanstvenih istraživanja i spoznaja o kvalitetnom ekstra djevičanskom maslinovom ulju. Danas se provode brojna istraživanja u cilju dobivanja što većih prinosa, ali i što kvalitetnijih i prepoznatljivih proizvoda. Jedan od važnih parametara kvalitete maslinovih ulja je određivanje količine ukupnih sterola i njihovog sastava. U ovom radu su za ispitivanje korišteni uzorci maslinovog ulja proizvedeni iz plodova šest domaćih sorti maslina s dubrovačkog područja: Piculje (2 uzorka), Paštrice (2 uzorka), Mezanice (2 uzorka), Bjelice (2 uzorka), Crnice (1 uzorka) i Uljarice (1 uzorak). Masline su ubrane sredinom listopada, studenog i prosinca 2015 godine. maslinovo ulje, steroli, plinska kromatografijaOlive oil today has become a synonym of healthy nutrition and modern living. There is growing scientific research and awareness of quality extra virgin olive oil. Numerous researches are being conducted today in order to obtain the highest yields, but also the quality and the most recognizable products. One of the important parameters of olive oil quality is determination of the quantity of total sterols and their composition. In this thesis samples of olive oil produced from six autochthonous varieties of olives from the Dubrovnik area: Piculje (2 samples), Paštrice (2 samples), Mezanice (2 samples), Bjelice (2 samples), Crnice (1 sample), Uljarice (1 sample) were analysed.
