Jackfruit (Artocarpus heterophyllus Lam.) is an ancient fruit that is widely consumed as a fresh fruit. The use of jackfruit bulbs and its parts has also been reported since ancient times for their therapeutic qualities. The beneficial physiological effects may also have preventive application in a variety of pathologies. The health benefits of jackfruit have been attributed to its wide range of physicochemical applications. This review presents an overview of the functional, medicinal, and physiological properties of this fruit.
Coconut plantation is abundant in konkan region of Maharashtra (India). Small landholders can improve their income through value added activities in downstream processing of coconut. One such activity would be to dry copra for preservation and subsequent oil extraction. Copra drying in konkan region is practiced largely through sun drying and chula drying. In both these drying methods, copra quality deteriorates significantly due to either open fire smoke, dust and mould growth in sun drying. There is need to have a natural convection indirect heating small mechanical copra dryer suited to the requirements of konkan farmers. This paper present design and testing of natural and forced convection indirect heating small mechanical dryer using agricultural waste as fuel. Components of dryer were drying chamber housing with two trays inside, heating chamber, burning cum heat exchanging unit i.e. furnace and chimney. The capacity of the dryer is 50 kg coconuts per batch (to hold coconut halves 50 % (w.b.) moisture content). The dryer was tested for drying performance in respect of drying air temperature, fuel consumption and quality of dried copra after the drying. The total area required for housing the dryer is 0.81 m 2. This is suitable dryer for drying of coconuts in rainy season when sun light is seldom available and chance of contaminants from quality point of view is minimum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
