Phycocyanin as a source of natural blue dye is unstable to light, temperature, and pH during processing and storage. Microencapsulation is used to protect phycocyanin from external influences where the type and formulation of coating materials used may affect the characteristics of phycocyanin microcapsules. This study aims to evaluate the physical properties of encapsulated phycocyanin from Spirulina and the potential of maltodextrin in combination with κ-carrageenan in its microencapsulation process by spray drying. Microcapsules were prepared with five different concentrations of maltodextrin and κ-carrageenan i.e., 10% : 0%; 9.75% : 0.25%; 9.5% : 0.5%; 9.25% : 0.75%, and 9% : 1% (w/w). Results indicated that microcapsules of phycocyanin with 9% of maltodetxrin and 1% of κ-carrageenan as coating material produced the highest bulk density, particle size, and encapsulation efficiency, which were 1,501.27 kg ∙ m–3, 1,152.33 nm, and 48.87%, respectively. The differential scanning calorimeter thermogram and the Fourier Transform Infrared Spectroscopy measured the presence of phycocyanin, maltodextrin, and κ-carrageenan in microcapsules.
