The Texture Analyser was set to the ‘adhesive test’ mode
with a test-speed of 0.3 mm/s. An acquisition rate of 50
points per seconds and a trigger force of 0.05N were
selected. An aluminium probe of 7.6 cm diameter was used
for all experiments with the exception of those conducted
in calcium chloride solution, as this corrodes aluminium.
A probe of same radius but made of stainless steel was used
for calcium chloride. The study was carried out at room
temperature ð20 CÞ.
