Fourier Transform Infrared Spectroscopy (FTIR)
In the context of a diploma thesis, the physical method of Fourier Transform Infrared Spectroscopy (FTIR) for determination of the most important beer parameters was evaluated at the Research Centre Weihenstephan for Brewing and Food Quality. The FTIR measurement method is based on transmission measured in the middle infrared range with which up to 15 beer parameters could be determined simultaneously. This article describes the measurement principle and use of infrared spectroscopy in beer analysis.
