at different temperatures and three

at different temperatures and three storage times, under linear viscoelastic conditions. From strain sweep runs, the upper limit of
the linear viscoelastic zone was located at strain of about 0.50. In
this domain, the experimental tests are essentially nondestructive
and can be interpreted in terms of the molecular structure of the
material[16]. All tests were carried out at least by duplicate.
2.5. Particle size distribution (PSD)
The PSD of emulsions were measured using a laser diffraction
analyzer in aqueous medium (Malvern MasterSizer model 2000
S). Refractive index of 1.400 and 1.330 were used for the emulsions and the reference (water, 1.33), respectively. The volumetric
diameterd(4,3) was analyzed as well as the specific superficial
area (SSA, m
2
/g) at different conditions of storage. The average
