Abstract

The paper presents a measurement system that is based on an array of non-specific sensors and the installation of both in a pilot and in an industrial mash tun. Three calibration strategies were pursued to predict gravity, FAN and β-glucan during mashing in combination with three different multivariate calibrations (PCR, CPCR, PLS). The over all best calibration had RMSPEs of 0.78%, 1.56 mg/100 mL and 181.73 mg/L for gravity, FAN and β-glucan, respectively. The measurement system makes it possible to monitor online the three major sub-processes of mashing (amylolysis, proteolysis, and cytolysis), which is the precondition for a situational control of the mashing process.
