2.4. Droplet size analysis
The water droplet size of the emulsions (25°C) was determined by NMR
using the droplet size probe of a Minispec Bruker model mq20 (Bruker
Analytik; Rheinstetten, Germany). The droplet size was measured in two
independent samples (n = 2) reporting the diameter of the water droplets
(µm) at the 97.5 percentile value (i.e., 97.5% of the droplets had a
diameter equal or below this value, WDD97.5%).
