Rheological measurements were carried out using an AR G2
Rheometer (TA instrument Inc., USA).The frequency sweeps tests
were performed on dough discs (50 mm diameter) using rough
surface parallel plates (50 mm diameter) with 1 mm gap at 25 C
Silicon oil was applied to the exposed surfaces of samples to prevent
evaporation during experiments . In order to relax the samples
before the measurements, all samples were allowed to rest for
15 min. Frequency sweeps tests from 0.1 to 10 Hz were performed
at 15 Pa within the linear viscoelastic region.Data for storage
modulus (G0), loss modulus (G00) and phase angle (tand) were
collected and used to compare the freezing effects.
