A new method for the proportion estimation in edible oil blends: sunflower and rapeseed oil

Abstract

Food authentication is the process by which a food product is verified as complying with its label description. The characterization and authentication of oils and fats is a subject of great importance for market and health aspects. The aim of this paper was to determine the possibility of applying a gas chromatography device with a mass spectrometric detector (GC-MS) coupled to a newly developed mathematical model to determine the proportion of individual oils in simulated blended oil samples.

Autentifikacija hrane je postupak kojim se potvrđuje usaglašenost prehrambenog proizvoda sa njegovim opisom na etiketi. Karakterizacija i autentifikacija ulja i masti je tema od velike važnosti sa tržišnog i zdravstvenog aspekta. Cilj ovog rada bio je da se utvrdi mogućnost primene uređaja za gasnu hromatografiju sa masenim spektrometrom kao detektorom (GC-MS) i novorazvijenog matematičkog modela za određivanje udela pojedinačnih ulja u simuliranim uzorcima smeša ulja.
