Abstract
Polifenoli su skupina spojeva koji značajno pridonose ukupnom okusu, mirisu i aromi piva, a osim na senzorska svojstva, utječu i na koloidnu stabilnost piva. Potječu iz biljnog materijala, slada i hmelja, te njihova koncentracija ovisi o vrstama i količini slada i hmelja koji se koristi u proizvodnji određenog tipa piva, ali i o samom procesu proizvodnje (filtracija, utjecaj kisika pri pakiranju i sl.). Polifenoli u pivu se sve više istražuju zbog svog pozitivnog utjecaja na zdravlje ljudi, odnosno njihove antioksidacijske aktivnosti. Zadatak ovog rada je odrediti antioksidativnu aktivnost i polifenolni profil različitih tipova piva (lager, pils, crno, tamno), pakiranih u smeđu staklenu ambalažu, a dostupnih na našem tržištu. Smeđa staklena ambalaža je odabrana jer se smatra najpogodnijom ambalažom tijekom skladištenja piva. Cilj rada je sukladno dobivenim rezultatima utvrditi koji polifenoli su najzastupljeniji u istraživanim pivima, koje pivo sadrži najviše polifenola i najveću antioksidativnu vrijednost.
Abstract (english)
Polyphenols are group of compounds that significantly contribute to the overall taste, beer aroma, and in addition to its sensory properties, they also affect the colloidal stability of beer. They originate from plant material, malt and hops, and their concentration depends on the types and quantity of malt and hops used in the production of a particular type of beer. The amount of polyphenols also depends on the production process itself (filtration, the influence of oxygen on packaging, etc.). Polyphenols in beer are increasingly being researched for their positive effect on human health, since they possess high antioxidant activity. The aim of this study was to determine the antioxidant activity and polyphenolic profile of different types of beer (lager, pils, black, dark), packed in brown glass packaging and available in our market. Brown glass packaging was selected because it is considered the most suitable packaging during beer storage. The aim of this study was to determine which polyphenols are the most represented in the studied beers, which beer contains the highest polyphenols and the highest antioxidant value.
