Mechanism of nanocapsules of Matricaria recutita L. extract formation by the emulsion-diffusion process

► Nanocapsules coated by medicinal plants have many applications in food flavoring and drug manufacturing. ► In high concentration of polymer, nanoparticle with large size will form. ► With a decrease in polymer concentration in organic phase, size of nanocapsules will decrease. ► When polymer/oil ratio rises, the size of particles will also raise accordingly.
