Microencapsulation of omega-3 fatty acids
A number of functional-food formulations were encapsulated by spray drying, and the protection from oxidation was studied. Microcapsules of gum arabic and of a ternary mixture of gum arabic, maltodextrin and whey protein isolate showed a high degree of protection and high microencapsulation efficiencies. These microcapsules also had smooth surfaces which kept unaltered during storage.
