Abstract

Eterično ulje komorača pokazuje mnoga antimikrobna i antioksidativna svojstva. Široko je primjenjivo u prehrambenoj i farmaceutskoj industriji, no zbog hlapljivosti i podložnosti oksidaciji, primjena mu je ograničena. Stoga je cilj ovog rada bio ispitati kako odabrani uvjeti sušenja raspršivanjem (temperatura od 120-200 °C i različiti omjeri nosača maltodekstrina i β-ciklodekstrina 1:1, 3:1, 1:3) utječu na fizikalno-kemijska svojstva (suhu tvar, topljivost, veličinu čestica, higroskopnost, iskorištenje, zadržavanje ulja i učinkovitost) praha eteričnog ulja komorača te odrediti optimalne uvjete za proizvodnju praha najboljih svojstava. Općenito, povećanjem temperature i udjela nosača maltodekstrina, raste topljivost, veličina čestica, higroskopnost, zadržavanje ulja i učinkovitost, dok porastom temperature i udjela nosača β-ciklodekstrina raste iskorištenje procesa. Sadržaj suhe tvari raste porastom temperature, dok udio nosača nije imao signifikantan utjecaj. Optimalni uvjeti za proizvodnju praha najboljih fizikalno-kemijskih svojstava su temperatura sušenja od 200 ºC i udio nosača maltodekstrina i β-ciklodekstrina 3:1.

Abstract (english)

Fennel essential oil shows many antimicrobial and antioxidant properties. It is widely applicable in the food and pharmaceutical industries, but due to its volatility and susceptibility to oxidation, its application is limited. Therefore, the aim of this study was to examine how the selected spray drying conditions (temperature of 120-200 °C and different ratios of maltodextrin and β-cyclodextrin carriers 1: 1, 3:1, 1:3) affect the physicochemical properties (dry matter, solubility, particle size, hygroscopicity, yield, oil retention and efficiency) of fennel essential oil powder and determine the optimal conditions to produce powder of the best properties. In general, increase of the temperature and content of maltodextrin carrier increases solubility, particle size, hygroscopicity, oil retention and efficiency, while increasing the temperature and content of β-cyclodextrin carrier increases process yield. The dry matter content increased with increase of the temperature, while the ratio of carriers did not have a significant effect. The optimal conditions for the production of powder with the best physicochemical properties are a drying temperature of 200 ºC and a ratio of maltodextrin and β-cyclodextrin carriers of 3: 1.
