Mechanism For Formation Of The Lightstruck Flavour In Beer Revealed By Time-Resolved Electron Paramagnetic Resonance

Time-resolved electron paramagnetic resonance (TREPR) data collected during the photodegradation of iso-a-acids (isohumulones), the principal bittering agents from hops in beer, are presented and discussed, and, from the data, the photophysics leading to free-radical production as the primary step in the photodecomposition of iso-a-acids towards the development of "skunky" beer are explained.
