Abstract
U ovom radu istraživan je utjecaj mikrovalnog zagrijavanja na oksidacijsku stabilnost hladno prešanog ulja chie pri različitim jačinama zagrijavanja i različitim vremenima mikrovalnog zagrijavanja. Također, ispitivan je utjecaj dodatka prirodnih antioksidanasa (ekstrakta ružmarina, ekstrakta zelenog čaja, ekstrakta nara) u udjelu 0,2 %, te sintetskog antioksidansa (0,01 %) propil galata. Oksidacijska stabilnost (održivost) ulja chie, sa i bez dodatka antioksidanasa, ispitivana je primjenom mikrovalnog zagrijavanja. Rezultati utjecaja mikrovalnog zagrijavanja pri različitim jačinama i različitim vremenima trajanja zagrijavanja, te utjecaj dodatka prirodnih i sintetskog antioksidansa prikazani su peroksidnim brojem (mmol O2/kg). Primjenom veće jačine mikrovalnog zagrijavanja dolazi do većeg oksidacijskog kvarenja chia ulja. Porastom vremena trajanja mikrovalnog zagrijavanja dolazi do smanjenja održivosti ulja chie što rezultira porastom peroksidnog broja. Dodatkom ispitivanih antioksidansa u ulje dolazi do promjene održivosti ulja chie. Veću efikasnost zaštite ovog ulja od oksidacije prikazuje ekstrakt ružmarina.
Abstract (english)
In this paper was investigated the effect of microwave heating on the oxidative stability of cold-pressed oil chie in different strengths of heating and different times of microwave heating. It also examines the influence of natural antioxidants (rosemary extract, green tea extract, pomegranate extract) in the proportion of 0.2%, and synthetic antioxidants (0,01%) propyl gallate. Oxidation stability (sustainability) chie oil, with and without the addition of antioxidants, was studied by using microwave heating. The results of the influence of microwave heating in different strength and different time during of heating, and the influence of natural and synthetic antioxidants are shown peroxide number (mmol O2 / kg). By using a more powerful microwave heating leads to higher oxidative deterioration chia oil. With increasing duration of microwave heating of a reduction in the sustainability of chie oil results in the increase of peroxide number. In addition of tested antioxidants in oil leads to change sustainability chie oil. Bigger efficient of protection of the this oil from oxidation shows rosemary extract.
