Measurements of pH were done using a Thermo Scientific Orion 3-
star benchtop pH-metre with spear-tip double junction pH electrode
VWR 662-0084 by introducing
the electrode in the centre of the sausage. The aw was measured in the
inner part of the sausages using a dew point hygrometer Aqualab CX-
2 (Decagon Devices, Pullman, WA) at 20 °C. All the determinations
were performed in duplicate.
