Abstract
U okviru ove disertacije sprovedena su ispitivanja valorizacije biljne prašine herbe hajdučke trave i ploda šipka, kao sporednih proizvoda nastalih u toku proizvodnje biljnog filter čaja, u smislu implementacije u nove proizvode, s obzirom na to da se radi o značajnoj količini biljnog sporednog proizvoda/otpada i da se pri tome radi o vrednoj sirovini koja i dalje sadrži određenu količinu značajnih bioaktivnih jedinjenja. Najpre je izvršena karakterizacija biljnog materijala, a zatim, primenom različitih tehnika, i njihova transformacija u biljne preparate-ekstrakte. U cilju pripreme biljnih preparata-ekstrakata, primenjene su tri ekstrakcione tehnike: klasična ekstrakcijamaceracija, sokslet ekstrakcija i ekstrakcija superkritičnim ugljen-dioksidom, a pored toga za transformaciju iz tečnog u suvu formu primenjena je tehnika sušenja sa raspršivanjemspray drying. Primenom različitih metoda analize utvrđen je sastav dobijenih ekstrakata. Ispitana je, takođe, i mogućnost inkorporacije spor...ednog proizvoda kao i dobijenih biljnih preparata u nove proizvode, te je u tom smislu, pripremljen i ispitan instant čaj od suvog ekstrakta hajdučke trave, dok se biljna prašina ploda šipka uspešno iskoristila za dobijanje funkcionalnog hleba.

As part of this dissertation, the valorisation studies of herb dust of Achillea millefolium and Rosa canina L fruit, as by-products of plant filter tea production, were conducted in terms of implementation into new products, given that it is a large amount of plant by-product / waste, and that it is a valuable raw material that still contains a certain amount of significant bioactive compounds. First, the characterization of the plant material was performed, and then, using various techniques, their transformation into herbal preparations-extracts. In order to prepare herbal preparations-extracts, three extraction techniques were applied: classical extraction-maceration, soxhlet extraction, and supercritical carbon dioxide extraction, and in addition, the spray-drying technique was applied for the transformation from liquid to dry form. The composition of the obtained extracts was determined using various methods of analysis. The possibility of incorporating the by-product as well as t...he obtained herbal preparations into new products was also examined, therefore instant tea was prepared and tested from the dry extract of A.millefolium, while the herb dust of the R.canina L fruit was successfully used to obtain functional bread.
