Abstract	Cilj ovog rada bio je istražiti promjene kvalitativnih svojstava cvjetova forzicije (Forsythia spp.) pod utjecajem različitih temperatura sušenja te odrediti količinu eteričnog ulja. Forzicija je široko rasprostranjena vrsta koja ima žute cvjetove te pripada porodici Oleaceae. U ovom diplomskom radu istraživanje je provedeno na svježim uzorcima forzicije koji su potom sušeni na temperaturama zraka od 40 ˚C, 50 ˚C i 60 ˚C. Dehidracijski postupak omogućuje cvijeću duži rok trajanja. Istraživanjem je utvrđeno da se povišenjem temperature sušenja ubrzavao gubitak vlage iz uzorka, rastao je udio pepela, vrijednost žute boje (b), kao i postotak masti. Zbog dobrog očuvanja boje nakon sušenja cvjetova te zbog utvrđenih mikro i makroelemenata, zaključuje se da se cvjetovi forzicije mogu koristiti kao jestiva dekoracija. Eterično ulje nije dobiveno vodenom destilacijom 353,05 g svježih cvjetova forzicije.
Abstract (english)	The aim of this study was to investigate the changes in the qualitative properties of forsythia flowers (Forsythia spp.) under the influence of different drying temperatures and to determine the amount of essential oil. Forsythia is a widespread species with yellow flowers and belongs to the family Oleaceae. In this thesis, the research was conducted on fresh forsythia samples which were then dried at air temperatures of 40 ˚C, 50 ˚C and 60 ˚C. The dehydration process allows the flowers to last longer. The research found that the increase in drying temperature accelerated the loss of moisture from the sample, increased the ash content, the value of yellow color (b), as well as the percentage of fat. Due to the good preservation of color after drying the flowers and due to the established micro and macro elements, it is concluded that forsythia flowers can be used as an edible decoration. The essential oil was not obtained by aquatic distillation of 353.05 g of fresh forsythia flowers.
