Important Aspects of Controlling Sulfur Dioxide in Brewing

This paper discusses the relative importance of sulfur dioxide (SO2) to brewers because there are implications to beer quality, consumer health, and legal requirements. Overviews are provided on what SO2 is, its sources in beer, what quality parameters are impacted by SO2,what health implications are known, and labeling requirements. An overview of methodologies for measuring SO2 is given to educate brewers on the advantages and disadvantages of different methods with the aim to enlighten brewers to adopt a method that can be incorporated into their quality assurance program. Finally, an overview of published papers is summarized, along with general trouble-shooting guidelines for brewers to further their knowledge on controlling this critical yeast metabolite in their beers.

啤酒酿造过程中控制二氧化硫的重要性

本文讨论了二氧化硫(SO2)对酿酒商的相对重要性,因为二氧化硫对啤酒质量、消费者健康和立法都有影响。文中概述了什么是SO2啤酒中SO2的来源,SO2影响的质量参数,已知的健康影响,以及标签要求本文对测定二氧化硫的方法进行了概述,使酿酒商了解不同方法的优缺点,以启发酿酒商采用一种可以纳入其质量保证计划的方法。最后,综述了已发表的论文,以及一般的解决问题的指南,供酿酒者进一步了解如何控制啤酒中这种关键的酵母代谢物。
