Encapsulation of cinnamic acid and galangal extracts in coconut (Cocos nucifera L.) liposomes

Abstract

Abstract Coconut liposomes are used to encapsulate cinnamic acid, red and white galangal extracts. Their encapsulation efficiencies and leakage rates are explored. The encapsulation efficiencies of cinnamic acid, red galangal and white galangal are 62 %, 42 % and 52 % respectively. Addition of 7 % cholesterol increases the encapsulation efficiency of cinnamic acid red galangal and white galangal to 70 %, 50 % and 68 % correspondingly. The red galangal extract has as much leakage rate as the cinnamic acid compare to white galangal extract at all liposomal systems.
