| Abstract | Zumbul je biljka podrijetlom s Balkanskog poluotoka i Male Azije. Uzgaja se zbog svojih
mirisnih cvjetova i zasluženo je omiljena proljetna lukovičasta biljka. Zumbuli su u vrtu
najdjelotvorniji posađeni u skupinama jedne boje ili u posudama uz kuću. Cvjetovi zumbula su
obojani od bijele, ružičaste, roze, ljubičaste, plavo-ljubičaste, crvene pa i žute boje. Izvrsni su za
uzgoj kao kućne lončanice; lukovice se kasnije mogu presaditi na otvoreno. Zumbul spada u
veoma omiljeno sobno bilje, pogodan je za sadnju na otvorenom: za ivičnjake, cvjetne lijehe,
bordure te kao cvjetna vrsta za rez. Esencijalno ulje zumbula koristi se u parfemskoj industriji.
Kako bi se očuvala svojstva latica zumbula, ponajviše boje, važno ih je termički doraditi
optimalnom kombinacijom temperature i vremena sušenja. Za potrebe istraživanja korištene su
latice roze, plavo-ljubičaste i bijele boje zumbula. Latice su sušene na tri različite temperature
(40°C, 50°C, 60°C).
Najbrže sušenje latica zabilježeno je pri temperaturi od 60°C. Ukupan sadržaj pepela, masti
te sadržaja škroba utvrđen je na svježim i sušenim laticama zumbula. |

| Parallel abstract (English) | Hyacinth (Hyacinthus orientalis L.) is a plant native to the Balkan Peninsula and Asia Minor.
It is cultivated for fragrance flowers and is deserved to be a favorite spring herbaceous plant.
Hyacinths are the most effective in garden in a single-color group or in a pot at the house. The
flowers are painted white, pink, violet, blue-violet, red and yellow. They are excellent for breeding
as home pots; later bulbs can be transplanted on open area. Hyacinth falls into a very favorite
indoor flowers, suitable for beams, flowerbeds, vases, cut flowers and forced cultivation. The
essential oil of the hyacinth is used in the perfume industry.
In order to preserve the characteristic of hyacinth petals, mostly color, it is important to
use optimal way of drying considering temperature and drying time. Pink, blue-violet and white
petals were used for the study. Petals were dried at three different temparatures (40 °C, 50 °C,
60 °C).
The fastest drying of petals was recorded at a temparature of 60 °C. The total ash content,
fat content and share of starch were determined on fresh and dried hyacinth petals. |
