Derivation and Application of a Simultaneous Volatile Formation and Stripping Kinetics Equation for Wort Boiling

Abstract

The paper showed the derivation of an equation to represent simultaneous dimethyl sulfide (DMS) formation and stripping during wort boiling. It also demonstrated a framework of linearization techniques for the resulting equation, which should facilitate its implementation. DMS formation and stripping were modelled by first-order rate equations with the rate constants k₁ and k₂ representing the rate constants for rate of DMS formation and DMS removal via stripping, respectively. The simultaneous processes of DMS formation and stripping were represented using an instantaneous differential mass balance. The resulting solution was seen to be similar to an equation stated previously by Mitani et al. Linearization of the derived simultaneous DMS formation and stripping model was done using a MacLaurin series coming from Taylor's series expansion.
