3.2. Evaluation of nano-encapsulation by different emulsions
At the first stage, nano-encapsulation of olive leaf extract was
performed by preparation of water-in-oil (W/O) nano-emulsions.
By measuring droplet size distribution in these primary W/O
nano-emulsions through laser light scattering, it was observed that
there are many small dispersed droplets with a size well below
