Tea is one of the most widely consumed beverages globally. Among the wide varieties, moringa-based tea is considered a nutritious drink and a traditional drink alternative, is rich in phytochemicals. By offering a nutritious, phytochemical-rich alternative like moringa tea, this study supports SDG 3 (Good Health and Well Being), ensuring healthier beverage options. This study uses three different drying techniques (hybrid solar drying, fluidized bed drying, and radio frequency (RF)) to dry the leaves and asses the nutritional profiles. Results say RF drying proved to be the most effective, and preserves the highest levels of essential nutrients than others. This aligns with SDG 12 (Responsible Consumption and Production), as RF drying promotes sustainable food processing by retaining essential nutrients in Moringa tea leaves. RF dried green tea curls exhibited the highest protein content (19.88%), crude fiber (9.96%), ash content (9.7%), Vitamin C (10.38 mg/100 g) and superior phenolic (52.23 mg GAE/g), and flavonoid contents (32.92 mg Catechin Eq/g), contributing to enhanced antioxidant capacity (70.02%). Color analysis indicated that RF drying produced darker tea leaves, especially in white and green teas, signifying more efficient moisture removal. The water activity was lowest in RF-dried black tea (0.35), suggesting improved preservation and shelf stability. The highest sensory score attained for black tea than others (white tea, green tea (both unfermented), oolong tea (semi-fermented)). These results underscore the advantages of RF drying in preserving the nutritional and sensory quality of moringa-based tea leaves, highlighting its potential as an optimal technique for tea processing.Graphical
