(An abstract of the dissertation submitted to the CCS Haryana Agricultural University, Hisar in partial fulfillment of the requirements for the degree of Master of Science) Value added matthi, papad, wadi, biscuit, sev and noodles were prepared using mothbean (varieties RMO-423 and RMO-435), fenugreek (variety Hisar Sonali) and spinach (variety S-23) in different proportions. The most acceptable ones were analysed for their nutritional value and shelf value. Chemical analysis of raw ingredients and the products prepared was done for their proximate composition, sugars, β-carotene, in vitro protein and starch digestibility, bioavailability of minerals and for antinutrients. Matthi prepared by supplementation with mothbean, fenugreek and spinach were found better for their protein, fat, ash, fibre, total calcium, iron and zinc content. However, the supplementation also increased the antinutrients significantly. Fenugreek and spinach also increased β-carotene content in matthi and all other products. In vitro protein digestibility of supplemented matthi increased significantly. Proximate composition, protein and starch digestibility and HClextractability of minerals of supplemented papad was similar to that of control. However, antinutritional factors calcium and iron content were increased on supplementation with mothbean, fenugreek and spinach. Protein content in wadi increased with mothbean. Fenugreek and spinach increased antinutrients ash, fibre, calcium and β-carotene content in wadi. Protein and starch digestibility were at par with control. HCl-extractability of calcium increased in supplemented wadi. Proximate composition of biscuits was found improved in all combinations for protein, ash, fibres, calcium and iron. Antinutrients increased while protein and starch digestibility decreased significantly in supplemented biscuits. HClextractability of calcium, iron and zinc increased after supplementation. Supplemented sev were found better in their proximate composition. Antinutrients were found increased in sev supplemented with fenugreek and spinach. Mineral content and their HCl-extractability increased after supplementation of sev. Proximate composition and sugar content were not changed in case of noodles after supplementation. Protein and starch digestability also remained unchanged. Calcium, iron and their HCl-extractability were found increased. Shelf life of biscuits and matthi was found quite satisfactory upto one month. It was good for papad, wadi, sev and noodles even upto two months. Fresh fenugreek and spinach leaves may be converted into dry powder which may be used round the year for preparing different value added products in combination with mothbean. Supplemented products have better acceptability due to their better nutritional quality. Therefore these value added products should be included in the diet of vulnerable groups due to their better nutritional quality.
