摘要
研究了啤酒强制老化过程中二氧化硫含量、抗氧化力评价指标与TBA值之间的相关性。Person相关性分析表明:二氧化硫含量与DPPH自由基清除活性、ABTS自由基阳离子清除活性、还原力和金属螯合性之间有显著的正相关性,TBA值与抗氧化评价指标及二氧化硫含量之间呈显著的负相关性。逐步回归分析表明:提高啤酒中DPPH自由基清除活性可以抑制啤酒老化的TBA值,对TBA的抑制力达到97.7%。
Correlation analysis among contents of sulfur dioxide,antioxidant activity assays and TBA in beer treated with forced-ageing was studied.Results from person correlation analysis showed that the content of sulfur dioxide showed significant positive correlations with DPPH radical scavenging activity,ABTS radical cation scavenging activity,reducing power and metal chelating activity.Significant negative correlations were found between TBA value and content of sulfur dioxide as well as antioxidant activity.Stepwise liner regression further demonstrated that the TBA value in beer could be inhibited by increasing the DPPH radical scavenging activity,and it made 97.7% of contribution to the level of TBA in beer.
