Abstract

Cilj ovog rada bio je odrediti udio i sastav sterola u sojinom ulju. Koristili smo 11 uzoraka sjemena različitih kultivara soje, uzgojenih 2015. godine na eksperimentalnom polju Agronomskog fakulteta u Zagrebu. Ulje je proizvedeno ekstrakcijom po Soxhletu uz heksan kao organsko otapalo. Udio i sastav sterola smo odredili metodom plinske kromatografije. Udio ukupnih sterola u uzorcima sojinog ulja je u rasponu od 3211 do 5162 mg/kg, dok je najzastupljeniji sterol u svim uzorcima β-sitosterol. U ulju su, također, detektirani kampesterol, kampestanol, stigmasterol, ∆5-avenasterol, ∆7-stigmasterol i ∆7-avenasterol.

Abstract (english)

The aim of this study was to determine sterols content and composition in crude soybean oil. We used 11 seed samples of different soybean cultivars grown on the experimental fields of the Faculty of Agriculture in Zagreb in 2015. Oil was produced by the Soxhlet extraction, using hexane as an organic solvent. We determined sterols content and composition using the method of gas chromatography. Content of overall sterols in samples of soybean oil are within range between 3211 and 5162 mg kg-1, while the most common sterol in all samples is β-sitosterol. Other sterols detected in oil were campesterol, campestanol, stigmasterol, ∆5-avenasterol, ∆7-stigmasterol and ∆7-avenasterol.
