The enthralling sweet taste that mesmerizes the eastern part of India, or more specifically the undivided Bengal (West Bengal and Bangladesh) is unveiled. The ethnic sweetmeats that originated in Bengal varied over their primary ingredients, size, shape, and process of production due to variation in the context of geographical, cultural, and religious beliefs. In total, thirty-eight numbers of sweet products that are originated in Bengal are reconnoitered along with their nutritional composition and shelf life. Based on the key ingredients, the sweetmeats can be divided into nine classes, namely, chhana-based, pulse-based, fried, milk-skin-based, extruded rice-based, fermented, khoa-based, fruit-based, and sugar-based. Nutritional heritage comes along with health-related benefits to mankind; the racial sweetmeats produced in undivided Bengal have crucial medicinal and gastronomical importance. The sweetmeats are basically the assimilation of ancestral Bengali tradition, rituals, and convictions through the cascade of time. The classical and folk processing methods practiced from antediluvian times have had a prominent impression on the taste and nutritional comportment of the sweets produced. To the best of our knowledge, this article is the first attempt to scientifically document the integrity of the processing methods, nutritional content, and health benefits of traditional sweetmeats.
Electric discharge machining is extensively used to process difficult to cut materials such as superalloys, composite materials etc. The quality of machining can be improved by adding particles into the dielectric fluid which is commonly known as powder mixed electric discharge machining (PMEDM). In the present study, titanium and graphite powder are added to dielectric fluid and the effects of the powders have been analysed on material removal rate, surface roughness, microhardness and surface morphology analysis. Six experiments have been conducted considering each powder with three different levels of pulse current 4A, 8A and 12A. The analysis of the result indicates MRR, surface roughness and microhardness significantly increase with the increase of pulse current. Titanium mixed EDM improves the MRR and microhardness but reduces the surface quality. The SEM investigations elucidate that the samples machined with Titanium powder mixed with EDM have fewer surface defects, cracks, microholes and layer deposition compared to the sample machined with Graphite powder.
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.
