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.

    Optimization of process parameters for cryogenic grinding of dried ginger
    (Department of Food and Agricultural Process Engineering, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 2016) Bhavya, Francis; KAU; Santhi Mary, Mathew
    The processing of spices requires additional care because they are sensitive to atmospheric parameters like temperature and light. The exposure to temperature during any of the processing stage may lead to their quality deterioration in terms of colour, volatile oil, volatile oil constituents, oleoresin content etc. The grinding of spices at cryogenic temperatures helps in retaining the heat sensitive components in the spices. This study envisages on the cryogenic grinding of dried ginger in order to optimize the grinding conditions, considering the important quality characteristics and compared the cryoground powder with the conventionally ground ginger. The physical properties which affect the grinding process directly or indirectly were also determined. The experiments on cryogenic grinding have been carried out for different feed rates and grinding temperature and the best combination was determined in terms of product quality as well as grinding characteristics. The optimized feed rate and temperature were 35 kg/h and -130±5°C. The lower temperature in the grinding zone solidifies the moisture and oil components in the raw material and makes it brittle, which facilitates the grinding easy and faster thus leads to less energy consumption. The extreme cold condition prevents the volatile oil loss and lead to their higher retention. The comparison of cryoground powder with the powder obtained by conventional method has shown that cryogenic grinding prevented the essential oil and oleoresin loss of ginger considerably and retained its constituents. The colour of cryoground ginger powder was superior and the particle size was finer. The time of grinding and specific energy consumption was found lower in cryogenic grinding. The packaging studies on ginger powder showed that laminated aluminum foil is suitable for long term storage.
