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.

    OPTIMIZATION OF PROCESS PARAMETERS FOR SPRAY DRYING OF PAPAYA LEAF JUICE
    (Acharya N.G. Ranga Agricultural University, 2017) ANU BABU, TAGARAM; SIVALA KUMAR
    The present work was undertaken to optimize the process parameters for spray drying of papaya leaf juice. The effects of inlet air temperatures (130, 140 and 150 oC), maltodextrin concentrations (8%, 10%, 12%) and feed flow rates (350, 475 and 600 mL/h) on the powder yield and physico-chemical characteristics of papaya leaf powder (moisture content, water activity, L* values, a* values, b* values, pH values and total flavonoid content) obtained by spray drying were studied. Response Surface Methodology (RSM) was used to investigate the optimum process conditions for spray drying of papaya leaf juice and to analyze the effects of inlet air temperatures, maltodextrin concentrations & feed flow rates on spray drying of papaya leaf juice. Response surface plots of dependent variables against process variables were studied. The different regression equations describing the process variables on the yield and physico-chemical characteristics were developed. The predicted models were adequate based on the coefficient of determination obtained. The papaya leaf juice for spray drying was prepared by adding different concentrations 8%, 10% and 12 % of maltodextrin as carrier agent to the concentrated papaya leaf juice. After adding maltodextrin, the papaya leaf juice was fed into the spray dryer under different feed flow rates such as 350, 475 and 600 mL/h and dried at different inlet air temperatures such as 130, 140 and 150 oC in a spray dryer. The storage period of papaya leaf powder was determined by measuring physico-chemical characteristics of spray dried powder for about 45 days. Spray drying of papaya leaf juice at the optimized condition of inlet air temperature 130 oC, maltodextrin concentration 8% and feed flow rate 350 mL/h has given yield, moisture content, water activity, L* values, a* values, b* values, pH values and total flavonoid content of spray dried papaya leaf powders as 20.22 g, 4.65%, 0.32, 51.12, -0.29, -73.88, 37.29, 6.43, 63.13 mg/g of powder, respectively. Moisture content, water activity, color characteristics, total flavonoid content (TFC) were significantly affected by maltodextrin concentrations, feed flow rates and the inlet air temperatures. pH of spray dried papaya leaf powders was not affected by inlet air temperatures and feed flow rates. An increase in moisture content and water activity were observed during storage period of 0 to 45 days. Slightly decrease of pH was observed with increase in storage period of 0 to 45 days. There was no loss of flavonoid content in papaya leaf powder during storage period of 0 to 45 days.
