Beer Sulphur Compounds Analysis

Beer is an extremely complex mixture in an aqueous environment and has more than 3,000 different compounds. Thus, it has been a considerable challenge for brewers to maintain beer quality throughout its lifetime. While it is inevitable that chemical changes will occur in beer with the passage of time, it is the formation of flavor-active components which is of immediate concern to an overview of beer shelf life stability. And sulfur dioxide is the most important factor in prolonging the shelf life, and delaying flavor staling of beer.

However, nowadays, it is found that certain sensitive individuals exhibiting adverse reactions to sulfites residues in foods. The use of sulfites in food products became an issue of concern to both consumer and regulatory agencies. Further investigations into this potential health hazard led agencies to promulgate regulations concerning the usage and labeling of sulfites. By both US and EU legislation, brewers can produce beers with sulfites content well below 10 mg L^-1.
