Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    STUDIES ON DEVELOPMENT OF CHITOSAN BASED BIOPOLYMER EXTRACTED FROM FISH SCALES AND ITS PERFORMANCE ON FOOD
    (guntur, 2022-08-18) MADHU, B. O.; SMITH, D. D.
    The waste generated from the worldwide production and processing of shellfish and fish scales is a severe problem of growing magnitude. The uncountable number of processed food products and raw materials of food available in the market are highly perishable and need effective and efficient packaging systems for extending their shelflife. Thereby, food waste may be minimized and the health of the consumer safeguarded. Conventional polymeric materials cannot be easily degraded in soil, which accumulates in the environment and aids in environmental pollution. Synthetic plastics are replacing biopolymers due to their renewable and biodegradable characteristics. Biopolymers generally synthesized from living organisms are polynucleotides viz., DNA, RNA, polypeptides (proteins) and polysaccharides (polymeric carbohydrates). Chitosan obtained from crustacean waste leads to useful utilization with the reduction in risk of environmental pollution. However, biopolymers generally have poor mechanical properties. To overcome this problem, plasticizers are added to provide the necessary workability to biopolymers. An antimicrobial film made from chitosan and clove oil helps in increasing in shelflife and quality of highly perishable food. The effect of concentrations of glacial acetic acid (0.5, 1, 1.5 %), plasticizer (10, 25, 40 %) and clove oil (0.5, 0.75,1 %) on Physico-chemical, mechanical and antimicrobial properties of developed biopolymeric films was studied. Response surface xvii methodology (RSM) was used to optimize the tensile strength, elongation at break, puncture strength, film thickness, swelling index, water vapor transmission rate, antimicrobial property (E Coli), antimicrobial property (Bacillus Subtilis), film density, biodegradability and color. A central composite rotatable design (CCRD) was used for optimization. Thus obtained optimized process parameters were glacial acetic acid concentration of 1.5%, plasticizer concentration of 10% and clove oil concentration of 1% with the results of tensile strength, elongation at break, puncture strength, film thickness, swelling index, water vapor transmission rate, antimicrobial property E Coli, antimicrobial property bacillus Subtilis, film density, biodegradability, L*, a*, b* and ΔE as 1.80E-05, 41.0376, 265.828, 0.060314, 68.3957, 3.67E-09, 34.2417, 32.1933, 1.19933, 52.1527, 84.6315, -0.30714, 10.4098 and 3.925 respectively. The effect of chitosan-based biopolymeric film on the shelf life of chicken nuggets and sapota fruits was evaluated along with LDPE, HDPE and PP packaging film as control for ten days based on firmness, weight loss, pH, TSS, color, and microbial load of food samples and determined the film developed with 1.5% glacial acetic acid concentration, 10% plasticizer and 1% clove oil showed good results and enhanced its shelf life.
