RESUMO
The study was performed on water spinach (Ipomea aquatica), a hidden gem with lots of nutritional attributes and medicinal properties. To check its feasibility as an ingredient in other food products and to know its nutritional attributes, powders were made by drying the leaves and stems of the plant using different drying techniques such as sun drying, freeze-drying, and tray drying. The physicochemical analysis of powder was done to get a comparative result, in which the freeze-dried powder showed the most significant result. The physicochemical analysis revealed that lyophilized water spinach powder has a good amount of carbohydrates (58.15%), ash (12.39%), protein (4.01%), and fat (4.46%) content. The powder also possessed a high antioxidant property of 77.25% and a total phenolic content of 32 µg/ ml. SEM and XRD results showed that the water spinach powder was amorphous in nature.
