The microencapsulation procedure in all the three cases
was carried out at 25 °C, and the liquid microcapsules/comicrocapsules
were kept at 5 °C for 48 h to ensure complete
formation of complex coacervates. Finally, the microcapsules/
co-microcapsules were dried to produce solid or powder comicrocapsules
(WPI-O-GA, WPI-P-GA and WPI-P-O-GA).
