Abstract Kuini powders were obtained through spray-drying, freeze-drying, vacuum oven drying and convection drying. Colour, water activity (Aw), moisture content, hygroscopicity, wettability, flowability, degree of caking, solubility index (WSI), total colour change, phenolic content carotenoid determined compared. Convection resulted in the highest yield (46.97%), (4.91%), Aw (0.55) WSI (74.33...
