The rheological properties of 1% gels were investigated using a
stress-controlled AR-G2 rheometer and a strain-controlled ARES
rheometer (TA Instruments). All tests were carried out at
25 ± 0.1C. As sample loading conditions influence testing, a
meticulous and consistent routine for sample loading was followed
to promote reproducible results. Prior to data collection, a 5-min
delay was applied to ensure rebuilding of the gel structure that was
compromised during sample loading. Four different types of measurement
results are reported:
