Phycocyanin is one of the pigments found in Spirulina platensis. Phycocyanin has potential as natural blue dye and antioxidant. The application of phycocyanin as food ingredient is still limited due to its vulnerability to environment. Microencapsulation can keep phycocyanin from environmental influences such as temperature, light and pH. This research aimed to determine the antioxidant activity of phycocyanin microencapsulation with carrageenan and chitosan coating material caused by the effect of thermal degradation overtime and its influence on the physical characteristics of the microencapsulation. The highest antioxidant activity of 61.48% was found in chitosan coating material that occurred at temperature of 40° with 30 minutes heat treatment.Phycocyanin microcapsule with chitosan has more vibrant blue color compared to carrageenan.Phycocyanin microencapsulation either by using carrageenan or chitosan have functional groups such as alkane, alcohol, ether and ester.
