2.2.2. Emulsion properties
Conductivity measurements were done using a conductimeter
to determine whether the emulsions were direct (the continuous
phase is water; high conductivity) or inverse (the continuous phase
is oil; zero conductivity). The granulometric analysis of emulsions
was done with a light scattering instrument (Mastersizer 2000
laser granulometer, Malvern, Malvern, UK). Stability was
monitored over time by measuring the emulsified volume (Ve)
compared to the total volume (Vt).
