PRODUCING COLD-PRESSED GRAPE SEED OIL FROM SYRAH GRAPE VARIETY

Cilj ovog rada je prikazati mogućnost proizvodnje hladno prešanog ulja iz sjemenki grožđa sorte Syrah, sušenih u sušioniku. Pokus se odvijao na način da su sjemenke odvojene od mesa grožđa i kožice (iz masulja nakon maceracije i tiještenja) te stavljene u sušionik, a nakon mjerenja vlažnosti stavljene u proces prešanja. Za obradu tih podataka korišteno je grožđe vinograda nastavne baze Veleučilišta u Požegi. Tijekom hladnog prešanja pozornost je bila na izlaznu temperaturu ulja i pogače. Ulazna količine vlage u sjemenkama utječe na izlaznu temperaturu ulja i pogače. Za dobivanje optimalne izlazne temperature i dobre kvalitete ulja, vlaga u sjemenkama ne bi trebala biti ispod 8%.The aim of this paper is to show the possibility of producing cold pressed oil from grape seed Syrah Variety, dried by dryer. The experiment was carried out in such a way that the seeds were separated from the grapes and skin (from the mash after maceration and pressing) and placed in a drier, and after measuring the moisture put into the pressing process. For processing these data, grape vineyards of the Požega Polytechnic's teaching base were used. During cold pressing, attention was given to the oil temperature and cake temperature. To obtain optimum output temperature and good oil quality, the moisture in the seeds should not be below 8%
