Abstract
Maslinova ulja se kategoriziraju ovisno o njihovoj kvaliteti. Na konačnu kvalitetu maslinovog ulja utječe više faktora kao što su kvaliteta plodova masline, postupak prerade i način čuvanja dobivenog ulja. U procesu prerade posebnu pozornost treba obratiti na postupak miješanja maslinova tijesta. Tijekom miješanja moguć je gubitak polifenola, što će u konačnici utjecati na kvalitetu maslinovog ulja i njegovu daljnju zaštitu od oksidacije. Nakon prerade dobiveno ulje se čuva u svježem i prozračnom prostoru pri konstantnoj temperaturi u posebnim spremnicima zaštićeno od kontakta s kisikom. Poznavanje oksidacijske stabilnosti ili održivosti ulja važno je kako bi se unaprijed moglo odrediti vrijeme za koje se ulje može sačuvati od jače izražene oksidacije, bez bitnih promjena kvalitete, naročito senzorskih svojstava. U ovom radu ispitivan je utjecaj temperature, vremena miješanja i vremena skladištenja na kvalitetu maslinovog ulja dobivenog iz plodova maslina sorte Oblica. Ispitivanja su pokazala da je najveću oksidacijsku stabilnost imalo maslinovo ulje dobiveno pri temperaturi miješanja 36 ℃ . Vrijeme miješanja nije imalo značajniji utjecaj na oksidacijsku stabilnost ulja.
Abstract (english)
Olive oils are categorized depending on their quality. The quality of olive oil ultimately is being determined by several factors, such as the quality of olives, procedure of processing and the way oil is being stored. In the processing procedure, special attention should be given to the process of olive doughs mixing. During the process of mixing, there is a possibility of polyphenols degradetion, which will ultimately affect the quality of olive oil and its further resistance to oxidation. After processing, obtained oil is kept in fresh and airy environment at a constant temperature in the special containers without contact with oxygen. Knowing the oxidation stability and sustainability of oil is important in order to predict for how long the oil can be preserved from stronger expressed oxidation without any significant changes in its quality, particularly sensory properties. In this paper the influence of temperature, mixing time and storage time on the quality of olive oil obtained from the Oblica olive variety was examined. The study revealed that the highest oxidation stability showed the olive oil obtained by mixing at temperatire of 36 ℃ . The mixing time had no significant effect on the oxidation stability of oil.
