Abstract
Prisutnost polifenola u pokožici predmet je brojnih istraživanja zbog njihovih pozitivnih učinaka na ljudsko zdravlje. Polifenolni spojevi u grožđu zastupljeni su u dvije osnovne kategorije: flavonoidi i neflavonoidi. U skupinu flavonoida ubrajaju se flavan-3-oli, flavonoli, flavanoli i antocijani, a u kategoriji neflavonoida zastupljeni su stilbeni, te fenolne kiseline (hidroksibenzojeve i hidroksicimetne). Najznačajniju razliku između crnog i bijelog grožđa čini prisutnost antocijanina u polifenolnom sastavu crnog grožđa. Pokožica bijelog grožđa nije dovoljno proučena u usporedbi s crvenim sortama, zbog nižeg sadržaja antocijanina i proantocijanidina. Međutim, pokožica bijelog grožđa bogat je izvor flavonoida i stilbena s važnim svojstvima za promicanje zdravlja. Sadržaj ukupnih fenolnih spojeva ovisi o raznolikosti prisutnih čimbenika kao što su svijetlost, temperatura, okoliš i agrotehničke metode. Za izolaciju fenolnih spojeva služe raznolike metode ekstrakcije koje se biraju prema određenim čimbenicima za pojedinu sortu.
Abstract (english)
The presence of polyphenols in the epidermis has been the subject of numerous studies due to their positive effects on human health. Polyphenolic compounds in grapes are represented in two basic categories: flavonoids and nonflavonoids. The group of flavonoids includes flavan-3-ols, flavonols, flavanols and anthocyanins, and the category of non-flavonoids includes stilbenes and phenolic acids (hydroxybenzoic and hydroxycinnamic). The most significant difference between red and white grapes is the presence of anthocyanins in the polyphenolic composition of red grapes. The skin of white grapes has not been sufficiently studied compared to red varieties, due to the lower content of anthocyanins and proanthocyanidins. However, the skin of white grapes is a rich source of flavonoids and stilbenes with important health-promoting properties. The content of total fenolic compounds depends on the variety of factors present such as light, temperature, environment and agrotechnical methods. A variety of extraction methods are used to isolate phenolic compounds, which are selected according to certain factors for each variety.
