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.

    Process optimization for development of natural gum hydrogel based biodegradable food packaging material
    (G.B. Pant University of Agriculture and Technology, Pantnagar - 263145 (Uttarakhand), 2021-02) Aman, Junaid; Shahi, N.C.
    The present study entitled, “Process Standardization for the Development of Natural Gum Hydrogel Based Biodegradable Food Packaging Material” was conducted in the department of Post Harvest Process and Food Engineering, College of Technology, G.B.P.U.A.T., Pantnagar, Uttarakhand. Guar is one of the most important and occurring plant in India which releases gum. During cultivation of the guar plant, huge amount of guar gum is generated as waste. Guar gum can be used for development of value-added product due to the presence of sufficient quantities of sugars like galactose and mannose and variety of valuable compounds such as phenols, fibres, unsaturated fatty acids and amides. Developed hydrogel film from guar gum 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 natural gum based hydrogel film, optimization and study of the characteristics. The experiments were conducted to study the effect of developed hydrogel film on physico-mechanical, biological, chemical and thermal properties. The independent variables selected were initiator (0.05, 0.10 and 0.15 mg/100ml GS), cross linker (0.02, 0.05 and 0.08 mg/100ml GS) and plasticizer concentration (2,4 and 6 ml/100ml GS). The biodegradation (%wt. loss), colour difference (ΔE), hardness(N), swelling index(%) and transparency(%) of the film were analysed. The data from all 17 experiments were analysed using Design Expert 11.0.1 and the response functions were developed using multiple regression analysis. The optimum level of variables for maximum desirability of developed hydrogel film were 0.146 mg/100ml GS initiator, 0.026 mg/100ml GS cross linker and 2.886 ml/100ml GS plasticizer concentration. The optimum values of responses were 21.495% (wt loss) of biodegradation, 5.460 (ΔE) of colour difference, 122.983 N of hardness, 213.44 % of swelling index and 59.36% of transparency. Significant (p<0.05) effect of process parameters were found in all responses in developed guar gum based hydrogel film. On validation of the model for responses of hydrogel film, it was found that the developed model was accurate as the prediction error was only in the range of -3.19 to 2.99%. At optimum condition of developed hydrogel film was characterized using moisture content, chemical interactions (FTIR and SEM) and thermal tests (TGA and DMA) and found to be significant.
