Abstract:
North east India is a rich and vibrant source of many indigenous plant produce. Because of lack of proper connectivity to the rest of India, local problems, language barriers and lack of proper infrastructure, many important plants and their parts are un-utililized though having high medicinal values and functional properties too. Tashe (Cyathea gigantea) is one among them species of tree fern. Due to high moisture content, it is difficult to store it for long period. Thus drying is most suitable means to reduce the moisture content but to retain its functional as well as medicinal properties three different types of drying techniques were taken into consideration namely sun, solar and tray drying. Solar drying was found to retain better quality of the dumplings of Tashe compared to those dried using Sun drying and tray dryer. Protein and carbohydrate content retention under solar drying was (1.25% and 61.85%) compared to tray drying (1.17% and 61.23%) and sun drying (1.12% and 60.66%). Antioxidant (% scavenging activity) retention under solar drying was (22.69%) compared to tray drying (19.47%) and sun drying (18.26%). By analyzing the effect on drying of tashe dumplings on the loss of moisture, overall colour change, retention of functional properties and sensory quality, it could be concluded that tray drying followed by solar is the best method and also at minimum cost and time (330 mins).
