Abstract: Moringa oleifera (Drumstick tree) is well known for its nutritional quality but usage of leaf powder as a functional ingredient is very less. Hence, the leaves were subjected to hot-air, solar-tunnel and shade drying methods and stored under ambient condition. Solar tunnel drying had 89.58 and 16.66% lesser drying time compared to shade and hot-air drying, respectively. The study showed that solar-tunnel dried leaf powder had high ascorbic acid (471 mg /100g), total carotenoids (2.49 mg/g), total polyphenols (39.29 mg gallic acid equivalent /g) and total chlorophyll (7 mg/g) content compared to other drying methods. Higher retention of bioactive compounds was found in solar-tunnel dried leaf powder during storage. Aerobic plate count was higher in shade dried sample throughout the storage period. It can be concluded from the study that solar-tunnel drying is the best green technology to obtain moringa leaf powder with high retention of bioactive compounds which can be utilized as a functional ingredient in food preparations.
