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.

    READY-TO-EAT ORANGE SEGMENTS BY MODIFIED ATMOSPHERE PACKAGING UNDER REFRIGERATED STORAGE
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) EEDA GOWTHAMI, Er; Er. K. LAVANYA
    Orange (Citrus sinensis), belonging to Rutaceae family evolved in the South East Asia and has excellent nutritive, medicinal and food values, may prevent and reduce the risk of degenerative and chronic diseases due to antioxidant activity. Readyto-eat/use and/or minimally processed food products have become popular due to their convenience, high value, unique sensory characteristics and health benefits. The change in food consumption patterns from ensuring an adequate supply of calories and nutrients with an increased emphasis on quality and consumer demand are required. Extending the shelf life of orange segments is important for domestic and export market. A study was undertaken to establish the most effective gas composition and packaging material for modified atmospheric packaging to extend the shelf life of orange segments. Fresh and sorted orange fruits were sanitized, dried, peeled and segmented. The citric acid treated and untreated orange segments (150 g) were packed under three different gas compositions i.e., 8% O2 + 15% CO2 + 77% N2 (G1), 5% O2 + 10% CO2 + 85% N2 (G2), 3% O2 + 5% CO2 + 92% N2 (G3) in different packaging materials like low density poly ethylene (LDPE, 60 µm), polypropylene (PP, 32 µm) and poly vinyl chloride (PVC, 20 µm). Physico-chemical, microbial and sensory characteristics were monitored at 50C for 25 days. The results showed that oxygen concentration gradually decreased but the carbon dioxide concentration gradually increased and reached a steady state concentration for both treated and untreated orange segments. The untreated orange segments could reach the steady state concentration at an early storage period compared to treated orange segments. The physiological loss in weight of treated orange segments packed in LDPE covers under G2 gas composition stored at 50C was less. The firmness and pH of treated orange segments packed in LDPE covers under G2 gas composition slightly increased and then decreased. The TSS and titratable acidity of treated orange Name of the Author : E. GOWTHAMI Title of the thesis : “READY-TO-EAT ORANGE SEGMENTS BY MODIFIED ATMOSPHERE PACKAGING UNDER REFRIGERATED STORAGE” Degree to which it is submitted : Master of Technology Faculty : Agricultural Engineering Major field of study : PROCESSING AND FOOD ENGINEERING Major Advisor : Er. K. LAVANYA University : Acharya N.G Ranga Agricultural University Year of Submission : 2015 segments packed in LDPE covers under G2 gas composition was decreased during storage period. The highest retention (reduction in ascorbic acid content was low) of ascorbic acid content was observed in treated orange segments packed in LDPE covers under G2 gas composition. The microbial count was less in treated orange segments packed with LDPE covers under G2 gas composition stored at 50C compared to PP, PVC covers and G1 & G3 gas compositions and control. In sensory evaluation, the LDPE packed, citric acid treated orange segments stored at 50C scored highest rating on hedonic scale by panelists in terms of visual appearance (4.45), aroma (4.47), texture (4.38), sweetness (4.3) and product acceptability (4.58). The shelf life of citric acid treated and untreated orange segments packed with LDPE covers under G2 gas composition can be enhanced up to 25 & 20 days respectively in comparison to only 4 days shelf life of control. However, the quality of LDPE packed treated orange segments under G2 gas composition stored at 50C is more acceptable.
