Abstract
Aroma maslinovog ulja sastoji se od složene mješavine hlapljivih spojeva nastale iz višestruko nezasićenih masnih kiselina lipoksigenaznim putem. Sastav hlapljivih spojeva u maslinovom ulju ovisi o sorti, stupnju zrelosti plodova i uvjetima prerade. Cilj rada je istražiti utjecaj ubrzanog toplinskog tretmana kao predtretmana miješenju na sastav hlapljivih komponenata djevičanskog maslinovog ulja. Za potrebe istraživanja korištene su 4 autohtone hrvatske sorte maslina: istarska bjelica, oblica, rosulja i levantinka. Također, usporedilo se korištenje toplinskog tretmana i ubrzanog toplinskog tretmana kod sorte oblica, odnosno utjecaj odabranog tretmana na nastanak poželjnih (spojevi nastali lipoksigenaznim putem) i nepoželjnih (produkti oksidacije) spojeva te je na temelju rezultata predložen optimalni toplinski tretman.
Abstract (english)
The aroma of olive oil consists of a complex mixture of volatile compounds, formed from polyunsaturated fatty acids via lipoxygenase pathway. The composition of these volatile compounds in olive oil is subject to variation based on the olive variety, stage of fruit ripening, and processing conditions. The aim of this study is to investigate the impact of flash thermal treatment as a pre-treatment of the malaxation process on the volatile components of virgin olive oil. In order to conduct this research, four indigenous Croatian olive varieties, namely Istarska Bjelica, Oblica, Rosulja, and Levantinka, were employed. Furthermore, the application of thermal treatment and flash thermal treatment was analyzed in the Oblica variety. Specifically, the study examines the effects of these treatments on the formation of desirable (compounds produced by lipoxygenase) and undesirable (oxidation products) compounds, and based on the findings, recommends an optimal heat treatment.
