University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    NUTRIENT COMPOSITION, ANTINUTRIENTS AND PROTEIN QUALITY OF WINGED BEAN [Psophocarpus tetragonolobus(l] DC] SEEDS
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) CHIMMAD, BHARATI V.; RAO, MEERA
    Winged 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.

    EFFECT OF PROCESSING AND STORAGE ON p-CAROTENE f CONTENT OF SELECTED FRUITS AND VEGETABLES
    (UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 1998-08-19) SEEMA, A.S.; Naik, Rama K.
    The effect of processing and preservation on p-carotene content was studied in selected fruits and vegetables. Preliminary survey results revealed that sun drying and pickling were the common methods of preserving vegetables and fruits. Open column chromatographic estimates of p-carotene (M-g/lOOg) content revealed that carrot contained highest (14,918.66) followed by green leafy vegetables (1,545.33 - 6,832.64), fruits (2,569.21 - 3,437.14), capsicum (856.65) and yam (820.76). Sulphited fruits, green leafy vegetables (GLV) and Capsicum retained higher amounts of p-carotene. Blanclied polyvinyl chloride cup packed vegetables and fruits recorded higher values for p-carotene as compared to low density polyethylene (LDPE) bag packed. Sulphited, shade dried GLV recorded significantly high p-carotene content after processing and consistently during storage. Significant reduction in P-carotene content of canned products was noticed with advancement of storage period (12 months). Brix preservation resulted in better retention of p-carotene and acceptable products. Frozen storage of vegetables and fruits resulted in 53.07 to 90.58 per cent loss of p-carotene content. However, sulphiting of vegetables and fruits enhanced the retention of P-carotene. Higher sensory scores were recorded for blanched LDPEpacked carrot, yam, sulphited LDPE packed capsicum and papaya. The p-carctene values, moisture content and rehydration ratio of GLV reduced with increasing storage period. Blanched and sulphited FLV showed lower moisture and higher rehydration ratio, respectively during storage. Rehydrated Harvi, Pundi, and Golli were highly acceptable even at 12 months of storage irrespective of the drying method. Among the processing methods, canning of carrot, and mango and shade drying of Honagone retained highest amount of p-carotene and were also acceptable. Sulphiting of fruits and vegetables was advantageous over blanching in retention of p-carotene. Packing of fruits and vegetables in LDPE aided in better retention of P~carotene as compared to PVC package.
