This study aimed to evaluating the phisycochemical characterization of encapsulated fish oil from menhaden and potential of maltodextrin in combination with different wall materials in its microencapsulation process by spray drying, in order to maximize encapsulation efficiency. Maltodextrin (MD) mixed with fish gelatin (FG), κ carrageenan (κc) and both of them. The feed emulsions used for particle production were characterized for stability. The best encapsulation efficiency was obtained for MD: FG followed by the MD: FG+ κc combination, while the lowest encapsulation efficiency was obtained for MD: κc, which also showed poorer emulsion stability. Particles were hollow, with the active material embedded in the wall material matrix, and had no apparent cracks or fissures.
