Assessment of black gram milling by-product as a potential source of nutrients

The present study was carried out to classify and explore the nutrient distribution of black gram milling by-product, with an intention to find value-added applications. The by-product was classified into two fractions, i.e., fraction BRGA (By-product Rich in Germ and Aleurone) and husk and their nutritional profiles were compared to cotyledon and whole seed (naive and germinated). BRGA found to be the richest source of protein (31.38%), minerals (Mg, Na, Fe, Zn and Mn) with appreciable amount of soluble dietary fiber (3.13%). Husk was the richest source of total dietary fiber (79.62%). Furthermore, both by-products were endowed with valuable essential amino acid and fatty acid profiles when compared to cotyledon and whole seeds. Overall, the present study revealed that the black gram by-product is a promising food ingredient that can be processed to obtain fractions rich in protein, fiber, essential fatty acids and minerals, for developing specialty foods for target population.
