Microencapsulation of DODECYL ACETATE (cas 112-66-3) by complex coacervation of whey protein with acacia gum and its release behavior

Add time:08/21/2019    Source:sciencedirect.com

Complex coacervation of whey protein (WP) with acacia gum (AG) was carried out in water with the presence of DODECYL ACETATE (cas 112-66-3) (DA), a component of insect sex pheromones, in order to obtain microcapsules with DA as the core material and WP–AG coacervate as the wall materials. Through variations in wall/core ratios, concentrations of the wall materials in capsule preparations, DA encapsulation was optimized, which showed a high DA encapsulation was achieved when coacervation was conducted at pH 3.5 with wall/core mass ratio at 3 combined with concentration of wall materials at 1.0 wt%. Morphology and the structure of DA loaded microcapsules were examined by scanning electron microscope, which showed the microcapsules were of core/shell structure with DA encapsulated in the inner of the microcapsules. DA release was examined and the behavior of the release was discussed.
