Despite the low antioxidant activity of pomegranate seeds, pomegranate seed oil (PSO) has very high antioxidant activity but is unstable. In this study, PSO was microencapsulated with natural materials and a clean label by spray drying. For this purpose, walls with different concentrations of cordia fruit gum (CFG) and maltodextrin were used. The creaming index of the emulsions was measured and, their physicochemical and oxidative stability properties were investigated. The results showed that microcapsules prepared by spray drying with a 6% CFG ratio had the highest encapsulation efficiency (88.11%), the smallest particle size (124.1 μm), the highest bulk density (0.38 g/cm3), the highest sphericity, and the highest oxidative stability. All the microcapsules' moisture contents fell below the 4% threshold that is considered acceptable for dry powders in the food sector. This study showed that using the microencapsulation as a clean-label technology (CL) system, it is possible to add value to pomegranate processing waste, thereby providing a sustainable method for using natural and indigenous ingredients that are generally recognized as safe (GRAS) in the food industry and an effective solution to solve the problem of oxidative stability of PSO.
