Abstract
U ovom radu ispitana je oksidativna stabilnost hladno presovanog ulja suncokreta visokooleinskog tipa primenom Schaal–Oven testa, pri povišenoj temperaturi (63±2 °C). Istovremeno su ispitani i uzorci hladno presovanog i rafinisanog ulja suncokreta, linolnog tipa. Stepen nastalih oksidativnih promena ispitivanih uzoraka sagledan je na bazi promena sadržaja primarnih i sekundarnih produkata oksidacije u periodu do 14 dana. Kod hladno presovanog ulja suncokreta visokooleinskog tipa utvrđen je najmanji porast oksidativne vrednosti, od 3,97 do 58,68 nakon 14 dana pri povišenoj temperaturi, u odsustvu svetlosti. Kod ovog ulja, stepen konjugacije u konjugovane diene je bio 2,73, a u konjugovane triene 1,53. Dobijeni rezultati ukazuju na znatno bolju (R2 ≥ 0,99) oksidativnu stabilnost hladno presovanog ulja suncokreta visokooleinskog tipa u odnosu na hladno presovano i rafinisano ulje suncokreta, linolnog tipa.
