The effect of spray-drying and freeze-drying on encapsulation efficiency, in vitro bioaccessibility and oxidative stability of krill oil nanoemulsion system

A nanoemulsion system was employed to encapsulate the krill oil with different concentration. The combination of whey protein concentrate, maltodextrin and gum arabic with the ratio of 8:2:0.5 was used in nanoemulsion formulation to enhance nanoemulsion stability, as well as to construct the wall part of the encapsulates. Two different drying methods; freeze-drying and spray-drying were applied on krill oil nanoemulsion systems to obtained...
