Increasing the antioxidant activity of beer itself could suppress the rate of oxidative reaction and improve the flavour stability of beer. This report describes the levels of phenolic compounds, melanoidins and sulfur dioxide, and antioxidant activities of 40 lager beers. The relationships between antioxidative compounds and antioxidant activity were elucidated by multivariate analysis techniques.<\/jats:bold><\/jats:p><jats:p><jats:bold>RESULTS: The results showed that the total phenolic content and the melanoidins content correlated well (<jats:italic>P<\/jats:italic> &lt; 0.05) with antioxidant activity, while there was no significant correlation (<jats:italic>P<\/jats:italic> &gt; 0.05) between total sulfur dioxide content and antioxidant activity. Satisfactory discrimination among beer samples with significantly different antioxidant activity was achieved by principal component analysis. Results from stepwise linear regression further demonstrated that different antioxidative components responsible for antioxidant activity were dependent on the assay used. The phenolic compound group is by far the most antioxidative compounds in beer and total phenolic content, melanoidins and sulfur dioxide together made a 22\u201368% contribution to the antioxidant activities of beers.<\/jats:bold><\/jats:p><jats:p><jats:bold>CONCLUSION: Therefore, it might be an efficient means for brewers to increase total phenolic content during brewing for improvement in flavour stability of the final beer. \u00a9 2012 Society of Chemical
