Govind Ballabh Pant University of Agriculture and Technology, Pantnagar

After independence, development of the rural sector was considered the primary concern of the Government of India. In 1949, with the appointment of the Radhakrishnan University Education Commission, imparting of agricultural education through the setting up of rural universities became the focal point. Later, in 1954 an Indo-American team led by Dr. K.R. Damle, the Vice-President of ICAR, was constituted that arrived at the idea of establishing a Rural University on the land-grant pattern of USA. As a consequence a contract between the Government of India, the Technical Cooperation Mission and some land-grant universities of USA, was signed to promote agricultural education in the country. The US universities included the universities of Tennessee, the Ohio State University, the Kansas State University, The University of Illinois, the Pennsylvania State University and the University of Missouri. The task of assisting Uttar Pradesh in establishing an agricultural university was assigned to the University of Illinois which signed a contract in 1959 to establish an agricultural University in the State. Dean, H.W. Hannah, of the University of Illinois prepared a blueprint for a Rural University to be set up at the Tarai State Farm in the district Nainital, UP. In the initial stage the University of Illinois also offered the services of its scientists and teachers. Thus, in 1960, the first agricultural university of India, UP Agricultural University, came into being by an Act of legislation, UP Act XI-V of 1958. The Act was later amended under UP Universities Re-enactment and Amendment Act 1972 and the University was rechristened as Govind Ballabh Pant University of Agriculture and Technology keeping in view the contributions of Pt. Govind Ballabh Pant, the then Chief Minister of UP. The University was dedicated to the Nation by the first Prime Minister of India Pt Jawaharlal Nehru on 17 November 1960. The G.B. Pant University is a symbol of successful partnership between India and the United States. The establishment of this university brought about a revolution in agricultural education, research and extension. It paved the way for setting up of 31 other agricultural universities in the country.

    Development of potato peel based biopolymer film and its performance on food packaging
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Surwade, Sachin Ashok; Khan Chand
    The present study entitled, “Development of potato peel based biopolymer film and its performance on food packaging” was conducted in the department of Post-Harvest Process and Food Engineering, College of Technology, G.B.P.U.A.T, Pantnagar, Uttarakhand during 2016-18. Potato is one of the most important crops in India. During the processing of the potato, huge quantity of potato peel waste is generated. Potato peel waste can be used for development of value-added product due to the presence of sufficient quantities of starch, cellulose, hemicellulose and fermentable sugars and variety of valuable compounds such as henols, dietary fibres, unsaturated fatty acids and amides. Developed biopolymer film from potato peel waste can be used as biodegradable food packaging material which might result in high commercial value use of the by-product. The research was therefore undertaken for development of potato peel based biopolymer film and its performance on food packaging. The experiments were conducted to study the effect of developed biopolymer film on physicochemical, mechanical as well as antimicrobial properties. The independent variables selected were potato peel extract (8, 10 and 12% w/v), glycerol concentration (10, 20 and 30 % v/v), acetic acid (2, 4 and 6 % v/v), drying temperature (40, 45 and 50⁰C) and film thickness (0.2, 0.25 and 0.3 mm). The moisture content (% wb), tensile strength (MPa), water vapour permeability (g/Pa h m), film transparency, colour difference and antimicrobial activity (CFU/ml) were analysed. The data from all 46 experiments were analysed using Design Expert 10.0.1 and the response functions were developed using multiple regression analysis. The optimum level of variables for maximum desirability of developed biopolymer film were 8.28% (w/v) potato peel extract, 10% (v/v) glycerol concentration, 2% (v/v) acetic acid, 50 ⁰C drying temperature and film thickness 0.3 (mm). The optimum values of responses were 8.27% (wb) of moisture content, 0.829 (MPa) of tensile strength, (0.498×10-5 g/Pa h m) water vapour permeability, 3.996 of film transparency, 25.501 of colour difference and 11.55×103 CFU/ml of antimicrobial activity. Significant (p<0.05) effect of process parameters were found in all responses in developed potato peel based biopolymer film. On validation of the model for responses of biopolymer film, it was found that the developed model was accurate as the predication error was only in the range of -0.23 to 13.76%. At optimum condition of developed biopolymer film the storage study of bread was found to be significant (p<0.05) during storage. Also, biodegradability characteristics of the developed biopolymer film showed 48.98% to 52.32% weight loss during 15 days of degradable period when buried under soil.

    Design, development and performance evaluation of drying cum storage bin for paddy (Oryza sativa L.)
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2018-06) Sruthi, N.U.; Lohani, U.C.
    The present study entitled, “Design, development and performance evaluation of drying cum storage bin for paddy (Oryza sativa L.)” was conducted in the department of Post-Harvest Process and Food Engineering, G.B.P.U.A.T, Pantnagar, Uttarakhand during 2016-18. Cereals such as rice, wheat and maize are particularly important to humans because of their role as staple food crops. India is the second largest producer of food grains globally. The principal food grain of India is rice. While fulfilling the food demand of an increasing population remains a major global concern, more than one-third of food is lost or wasted in postharvest operations. As much as 50 to 60 % cereal grains are lost during the storage stage due to the lack of technical efficiency, rice facing the highest loss. Therefore, an effort was made to develop a drying cum storage bin for paddy where heated air was supplied to the grain bulk from a central perforated duct. A temperature sensor, digital controller and air exhaust valve regulates the temperature and air flow rate in the bin. The air passes horizontally through the grain bulk taking up the moisture and moves towards the perforated walls of the bin and proceeds towards the exhaust. Drying experiments were conducted to analyse the drying characteristics of paddy and thereby evaluate the performance of the dryer. Paddy was dried from 18 % moisture content (wb) to 12 % moisture content (wb). A full factor design with two independent variables at three levels was used for conducting the experiments. The independent variables selected were drying air temperature (35, 40 and 45 °C) and air flow rate (15, 21 and 27 m3/h). The total drying time (h), effective moisture diffusivity (m2/s), heat transfer coefficient (W/m2K) and specific energy consumption (kJ/kg) were determined. The data from all 9 experiments were analysed using Design Expert 10.1.1.0 and the response functions were developed using multiple regression analysis. There was minimum variation in the drying data of the top and bottom basins showing that the drying occurred uniformly throughout the depth of the bin. The optimum level of variables for maximum desirability of cross flow aerated paddy drying were 45°C temperature and 27 m3/h air flow rate. The optimum values of responses were 1.51 hours of drying time, 6.05x10-7 m2/s of effective moisture diffusivity, 0.078 W/m2K of heat transfer coefficient and 823537.1 kJ/kg of specific energy consumption. Significant (p<0.05) effect of process parameters were found in all responses. On validation of the model for drying of paddy, it was found that the developed model was accurate as the prediction error was only in the range of -1 to 9.58 %
