Abstract

U istraživanju je ispitan antimikrobni i antioksidacijski učinak uobičajenih i komercijalno dostupnih eteričnih ulja, kao alternativa sintetičkim konzervansima. Upotrijebljeni su sljedeći biljni izvori: lavanda (Lavandula angustifolia), čajevac (Melaleuca alternifolia), bergamot (Citrus bergamia) i paprena metvica (Mentha piperita). Antioksidacijska aktivnost eteričnih ulja ispitana je pomoću 2,2-difenil-1-pikrilhidrazil (DPPH) i 2,2′-azinobis (3-etilbenzotiazolin-6-sulfonska kiselina) (ABTS). Mikrodilucijska metoda pokazala je da su eterična ulja lavande i bergamota bila učinkovitija u inhibiciji rasta bakterija od drugih ispitanih ulja, uz minimalnu inhibicijsku koncentraciju od 5 μg/mL. U radu se također opisuje uspješnost primjene elektrostatske ekstruzije za inkapsulaciju eteričnih ulja u alginatne kuglice, što omogućuje zadržavanje sposobnosti neutralizacije slobodnih radikala eteričnih ulja tijekom vremena.
