摘要: Summary In this work, the effect of solvent type on characteristics unsaturated fatty acids/chitosan microcapsules was evaluated. The acids were obtained from carp oil and chitosan shrimp wastes. emulsion containing an aqueous phases. In phase, ethanol hexane evaluated as solvents. characterized according to encapsulation efficiency, peroxide values scanning electron microscopy. results revealed that with showed efficiencies 79.6 69.4%, respectively. lower values, these maintained during 30 days. Furthermore, spherical irregular, mean diameter ranging 0.5 2.5 µm. These indicated more adequate obtain microcapsules.
