Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Development and evaluation of an ultra violet radiation assisted with ohmic heating system for preservation of pineapple juice
    (Department of Food and Agricultural Process Engineering, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 2015) Dileep, Sean Y; KAU; Prince, M V
    Ultraviolet (UV) radiation is one such non-thermal processing alternative that has been shown to be effective against many types of foodborne pathogens. But there is a limitation of practical application of UV to disinfect liquid food products due to low penetration depth. Ohmic heating (OH), another promising technology, has been widely applied in food processes. This generates heat immediately in the food product, creating a rapid and uniform heating that reduces thermal abuse, as opposed to conventional thermal processing methods. Often times, ohmic heating cause heat-sensitive nutrients within food to be deteriorated by excessive current flow. These advanced technologies could contribute to shorten processing times, energy savings, and highly balanced safe food; however, they alone still cannot guarantee food safety without damaging the food’s quality. Therefore, a new concept to combine ultraviolet and ohmic heating has been extensively evaluated. This combination technology would optimize each of the individual technology’s strengths and reduce each of their individual weaknesses. The present study envisages development of a UV radiation assisted with ohmic heating system for pineapple juice and evaluation of the developed system in retaining the quality characteristics and microbial safety. In this study, a dual cylindrical ohmic and ultraviolet treatment combination continuous flow chambers was designed and fabricated to pasteurize the pineapple juice. UV treatment 800, 1200 and 1600 mJ/cm2. Ohmic treatment until the sample temperature reached 50°C, 55°C and 60°C; and ohmic heating combined with UV treatment as the temperature rose to 50 °C, 55 °C, and 60 °C along with 800, 1200 and 1600 mJ/cm2 dosages. Combined ohmic heating at 50 °C and UV treatment of 1200 mJ/cm2 were found to be superior based on biochemical, microbiological and organoleptical characteristics. Storage study of best sample revealed that could give a shelf life of 25 days under a refrigeration temperature at 4 °C retaining its biochemical characteristics while keeping the microbial level safe.
