Chia seed protein (CPI)-chia seed gum (CSG) complex coacervates were used to encapsulate chia seed oil.
The complex coacervate shell provided very high oxidative stability to the chia seed oil.
Use of complex coacervate as shell materials yielded higher encapsulation efficiency.
Core-to-wall ratio of 1:2 yielded >92% encapsulation efficiency and >96% encapsulation yield.
Spray-dried microcapsules showed higher oxidative stability than the freeze-dried ones.
