Significance of SO2 in beer. Part 3: Factors which effect on production of sulphur dioxide during brewing fermentation.

Abstract

In this article the effect of yeast brewing strains and technological conditions on the production of sulphur dioxide are studied. The decrease of sulphur dioxide during the storage, its influence on the improvement of the oxidative and the stale flavour of beer and also the correlation between its concentration in beer and redox capacity of beer are monitored in this study.In this article the effect of yeast brewing strains and technological conditions on the production of sulphur dioxide are studied.
