2.3. Measurement of droplet diameter distribution
Droplet diameter distribution of oil body-based dispersion was
determined with the aid of a laser light scattering instrument
(Malvern Mastersizer 2000, Malvern, UK) (Nikiforidis &
Kiosseoglou, 2009). Measurements are reported as the surface
weighted ( d3:2 ¼ P
nid3i
=
P
nid2i
) mean diameter, where ni is the
number of droplets with a diameter of di. Sodium dodecyl sulfate
(SDS) (Sigma Chemical, St. Louis, USA) at a concentration of 0.01%
(w/w) was added to ensure the full dispersion of any aggregated
droplets.
