dc.description.abstractWinged bean [Psophocarpus tetragonolobus (L) DC] is an underexploited multipurpose crop. Winged bean seeds of 59 genotypes grown at ARS, Siruguppa, UAS, Dharwad were studied for their physico-chemical characteristics and nutrient composition. Thirteen genotypes were processed by soaking, decortication and pressure cooking and changes in nutrients and antinutrients assessed. Protein quality ofpresoaked pressure cooked broth retained (PPCB) seeds was assayed by protein cflicicncy ratio (PliR), digestibility coeiricicnt (DC), biological value (BV), net protein utilization (NPU) and net dietary protein calories (NOP Cal%). Significant varietal dilTcrences in physico-chemical characteristics and nutrient composition existed. Seedcoat colour varied from cream, brown, grey, mixed colours to black. Seed weight and volume positively influenced the physico-chemical characteristics. Hardseeds influenced them inversely. Mean crude protein content was 33.70%, fat 17.74, crude fiber 5.97, carbohydrate 27.75, calcium 0.24 and iron 0.14. Dhal recovery by domestic method was 59.72%. Decortication decreased the levels of crude fiber (to 0.24%), carbohydrates (27.36%) and calcium (56.64 mg) while the crude protein (37.70%), fat (22.55%), iron (4.01 mg) and calorific values (463 K Cal) increased. Concentration of antinutrients such as tannins, total free phenols, phytic acid and trypsin inliibitors varied among the genotypes and domestic processing techniques altered them. Tannins and phytic acid content increased with seed weight. Maximum reduction of tannins (47.26%) and trypsin inhibitors (59.27%) was in PPCB samples. Total free phenols were reduced maximum by decortication (57.66%) and phylates by presoaked pressure cooked broth rejected seeds (27.00%). Tannins inversely influenced the physico-chemical characteristics, while trypsin inhibitor levels did not affect them. Food intake, PER, DC, B V, NPU and NDP cal % of rats fed winged bean diet were lower than those on albumin diet. Winged bean diet did not affect rat liver and spleen weights. Thus, physico-chemical characteristics, nutrients, antinutrients varied. Pressure cooked seeds promoted rat growth.en_US
