pH and electric field-responsive microparticles composed of cinnamoyl gelatin (CinGel) and cinnamoyl nanocellulose (CinCNC) were prepared by the emulsion method. CinGel and CinCNC were prepared through a condensation reaction. The content of cinnamic acid (CA) residue in CinCNC(3/1), CinCNC(4.5/1), CinCNC(6/1), and CinGel was evaluated to be 15.33%, 11.03%, 2.96%, and 1.56%, respectively. The complexation of CinGel and CinCNC(3/1) in an aqueous solution took place when the pH value of the medium was 3.0 and 4.5. The maximum complexation was obtained when the CinGel/CinCNC(3/1) mass ratio was 3:7. CinGel/CinCNC(3/1) microparticles were prepared by water in oil emulsion method. The release degree of amaranth at pH 8.0 was higher than the release degree at pH 3.0, pH 4.5, and pH 5.5, possibly because of the complexation of CinGel and CinCNC(3/1) under the acidic condition. When increasing the voltage, the release degree would increase. The charge of the microparticle was negative and it would move to the anode. The pH value near the anode can decrease because H+ is produced at the electrode due to water electrolysis. The microparticle was pH-sensitive and it would easily release its content.
