Abstract: In general, value addition refers to adding economic value to a product. Value-added food items are being developed to address calcium and vitamin D deficiencies. Blood coagulation, neuromuscular transmission, and muscle contraction all require calcium. Tetany, rickets, osteomalacia, and osteoporosis are some of the consequences associated with calcium deficiency. Vitamin D, on the other hand, is essential for cell growth, immunological function, and bone mineral density maintenance. Processed egg shell and sun dried mushroom have recently been added to the list of calcium and vitamin D sources, respectively. Eggshell is made composed of 94% calcium carbonate and has been shown in studies to help people with osteoporosis boost bone density and reduce discomfort. On other side since ergosterol is found in milligram amounts in mushrooms, converting a modest amount of ergosterol to vitamin D results in a nutritionally significant rise in vitamin D.

Key words: Value addition, calcium, vitamin D, egg shell, mushroom
