Abstract

Kukuruzna krupica se u proizvodnji piva koristi kao jeftinija zamjena za ječmeni slad. Cilj ovog istraživanja bio je odrediti utjecaj udjela kukuruzne krupice na kvalitetu piva donjeg vrenja. Provedena je analiza piva proizvedenog od čistog slada, te piva sa 18%, 30% i 40% kukuruzne krupice. Tijekom istraživanja praćeni su ovi pokazatelji kakvoće piva: pH, boja, gorčina, bistroća, sadržaj ekstrakta i prevrelost. Rezultati istraživanja pokazuju da udjel kukuruzne krupice u usipku ima značajan utjecaj na kvalitetu piva, a utvrđeno je da optimalni udjel iznosi 30 %.

Abstract (english)

Corn grist is used in beer production as a cheaper replacement for barley malt. The main goal of this research is to determine the effect of corn grist content on lager beer quality. In this investigation following parameters of beer quality were monitored in beers with 0, 18, 30 and 40 % of corn grist: pH, colour, bitterness, haze, extract content and fermentability. Obtained results have shown that the content of corn grist has considerable effect on the beer quality, and its optimal content in mash is 30 %.
