Stabilizers for increased colloidal stability of beer.

Abstract: Pivo je ve světě velmi oblíbený nápoj. Protože spotřebitelé vyžadují kvalitní čiré pivo s čerstvou chutí a vůní, správnou barvou a pěnivostí, jsou kladeny stále větší nároky na jeho stabilitu. To je dáno také tím, že v současnosti, kdy je mnoho druhů piv určeno na export, uplyne poměrně dlouhá doba, než se hotový nápoj dostane do rukou konzumenta. I z tohoto důvodu jsou pivovary nuceny používat nejrůznější prostředky pro zajištění dlouhodobé trvanlivosti piva [1].Na koloidní stabilitu mají negativní vliv přede… Show more

“…The visual quality of a beverage is of great importance to consumers. Any visible haze in light lager-style beers (turbidity level of more than 2 EBC (European Brewery Convention) units) [15] is often identified with microbial contamination [16]. Therefore brewers are required to produce consistent quality beers, exhibiting no physical changes across the whole shelf life.…”

“…Beer, however, is an inherently unstable fermented beverage [17]. Its physicochemical properties such as clarity and its overall quality gradually deteriorate during storage, especially under poor storage conditions such as elevated temperature, movement, or light [16]. The rate of deterioration particularly depends on the chemical composition of the beer, which in turn is determined by the type, quality, and amount of raw materials used in the manufacturing process, as well as by the treatments applied to the wort and beer.…”
