In contrast to other authors (Zou et al., 2011), we did not report
rejected material such as filamentous masses of polymer, which
could negatively affect the textural and organoleptic properties of
food products in which the microparticles could be added (Anal &
Singh, 2007). This result shows that the time and the shaking
speed used in the elaboration of microparticles seem to be suitable
for the diffusion of calcium ions through alginate gel which is a key
step in the formation of the microparticles. White arrows in Fig. 1B
show small and dark droplet into the particles which is due to the
presence of residual oil used in the synthesis of microparticles.
