Abstract
'Plavac mali crni' gospodarski je najvažnija crna sorta vinove loze na području RH-a. Tehnologija prerade grožđa ima značajan utjecaj na polifenolni sastav mošta odnosno budućeg vina. Klasični način prerade podrazumijeva istovremeno protjecanje maceracije i alkoholne fermentacije. Maceracija crnih vina provodi se zbog ekstrakcije antocijana i ostalih polifenolnih spojeva koji su zaslužni za boju i strukturu vina. Temperatura maceracije izravno utječe na sadržaj i sastav spomenutih spojeva u moštu odnosno vinu što posljedično ima utjecaj na samu kvalitetu i tip vina koji želimo proizvesti. Niže temperature u pravilu smanjuju ekstrakciju polifenolnih spojeva Rezultati istraživanja pokazali su da temperatura maceracije masulja pri 30 ℃ omogućava bolju ekstrakciji ukupnih antocijana, te posebice malvidin-3-glukozida. Kod maceracije provedene na 25 ℃ primjećuje se značajniji rast vrijednosti u skupini spojeva flavonol glikozida.
Abstract (english)
'Plavac mali crni' is economically most important red grape variety in the territory of the Republic of Croatia. Grape processing technology has a significant influence on the polyphenolic compostion of the must or future wine. The classic method of processing involves simultaneous maceration and alcoholic fermenation. Maceration of red wines is carried out for the extraction of anthocyanins and other polyphenolic compounds responsible for the color and structure of the wine. The maceration temperature directly affects the content and composition of the mentioned compounds in the must or wine, which consequently has an impact on the very quality and type of wine we want to produce. As a rule, lower temperatures reduce the extraction of polyphenolic compounds. In this research results showed that the maceration temperature of a must at 30 ℃ enables better extraction of total anthocyanins, and especially malvidin-3-glucoside. Maceration carried out at 25 ℃ shows significant increase in values in the group of flavonol glycoside compounds.
