Abstract

The subject of this article is the impact of foam on the vaporization of dimethyl sulfide (DMS) out of wort during boiling. For this purpose a boiling process for vaporization of DMS is calculated for a laboratory scale and validated in terms of DMS reduction with two trial series. The first trial series consists of wort boiling without foam, whereas the second one consists of wort boiling with foam. DMS reduction is calculated and measured for both series. Thus, it is possible to determine foam's impact on the thermodynamic separation effect of wort boiling. As a result, it has to be stated that foam during wort boiling leads to an enhanced vaporization of DMS.
