Abstract
Jedan od glavnih problema prilikom proizvodnje, primjene i prerade jestivih ulja je oksidacija lipida, ona uzrokuje važnu promjenu kemijskih, senzorskih i nutritivnih svojstava. U ovom radu istraživan je utjecaj sintetskog antioksidansa propil galata (0,01 %) i prirodnih antioksidanasa ekstrakta ružmarina OxyLess.CS (0,1 % i 0,3 %) i ekstrakta zelenog čaja (0,1 % i 0,3 %) na oksidacijsku stabilnost smjese sezamovog ulja i ostalih vrsta biljnih ulja (50 : 50). Za ispitivanje oksidacijske stabilnosti korištene su sljedeće vrste biljnih ulja: sezamovo ulje, kikirikijevo ulje, orahovo ulje, bademovo ulje, repičino ulje, ekstra djevičansko maslinovo ulje. Određivanje oksidacijske stabilnosti ulja, njihovih kombinacija, te utjecaj antioksidansa (propil galata, ekstrakta ruţmarina i ekstrakta zelenog čaja) provedeno je testom ubrzane oksidacije ulja – Oven testom (63 °C). Rezultat oksidacije ulja izražen je peroksidnim brojem (Pbr) tijekom 4 dana testa. Dodatkom sezamovog ulja (50 %) u druge vrste ispitivanih biljnih ulja došlo je do porasta stabilnosti smjese ulja prema oksidacijskom kvarenju. Prirodni antioksidansi ekstrakt ružmarina OxyLess.CS i ekstrakt zelenog čaja efikasnije štiti smjesu ulja od oksidacijskog kvarenja u odnosu na dodatak sintetskog antioksidansa propil galata.
Abstract (english)
One of the major problems during production, application and processing of edible oils is oxidation of lipids, it causes an important change in the chemical, sensory and nutritional properties. In this paper, monitored the influence of synthetic antioxidants propyl gallate (0,01%) and natural antioxidant: extracts of rosemary OxyLess.CS (0,1% and 0,3%) and green tea extract (0,1% and 0,3%), on the oxidative stability of sezame oil mixtures and other types of vegetable oil (50:50). To test the stability of oxidation were used the following types of vegetable oils: sezame oil, peanut oil, nut oil, almond oil, rape oil, extra virgin olive oil. Determination of oxidation stability of oils and their combination, and the impact of antioxidant (propyl gallate, extracts of rosemary and green tea extract) conducted with a test of rapid oxidation of oils – Oven test (63 °C). The result of oil oxidation expressed peroxide value (PV) during 4 days of the test. The addition of sesame oil (50%) in other vegetable oils tested, there was an increase in the stability of a mixture of oil degradation by oxidation . Natural antioxidants OxyLess.CS rosemary extract and green tea extract effectively protects the oil mixture from oxidative deterioration as compared to the addition of synthetic antioxidants propyl gallate.
