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 process protocol for vacuum fried bitter gourd chips (momordica charantia)
    (Department of Processing and Food Engineering, Kelappaji College of Agricultural Engineering and Technology, Tavanur, 2018) Pooja, M R; KAU; Sudheer, K P
    Bitter gourd (Momordica charantia) is commonly known as bitter melon or Karela in India. The estimated post harvest loss of bitter gourd was 25%. A realistic solution to reduce the post harvest loss in bitter gourd is the adoption of the appropriate processing technologies. The vacuum frying is an excellent promising technology, in which food is fried under low pressure and temperature. Vacuum frying reduces the oil absorption, less formation of acrylamide content, and retains the colour and nutrients present in fried products. The vacuum frying system consists of two main chambers namely, frying chamber and oil storage chamber. A de-oiling system is attached to frying chamber to remove the oil content in the final vacuum fried product. This vacuum frying system used for the study was batch type and had a capacity of 3 kg/ batch with oil tank storage of 30 l. After every batch of vacuum frying, chips and oil were collected for analysing the quality. The blended oil (rice bran and palm oil at 80:20) was used as frying oil and de-oiling was done at a speed of 1000 rpm for 5 min. Different pre- treatments were done for vacuum fried bitter gourd chips. Control (Un-treated) sample had the best qualities with less oil content (4.43 %), moisture content (0.264 %), hardness (1.422 N), water activity (0.250) and green colour retention (a*(-4.13)). Quality parameters like moisture content, water activity, oil content, bulk density, true density, hardness, energy content, acrylamide content, thickness expansion, colour values and sensory evaluation of vacuum fried bitter gourd chips were analysed at different frying conditions. The treatment condition at 100oC, and 9 kPa vacuum for a duration of 10 min produced good quality parameters with less oil content (4.011%), acrylamide content (56.52 ppb), hardness value (1.411 N), high retention of green colour (a*(-5.3)) and good organoleptic properties (Hedonic score of 8.7). The laminated aluminium flexible pouches with nitrogen flushing retained the quality of bitter gourd chips during the storage period. The TPC value of blended oil increased from an initial value of 9.4 to 24.21%, due to continuous usage of oil (70 times) under the vacuum frying process, and was within the safe limit. The FFA value of blended oil was within the acceptable limit upto 50 cycles of vacuum frying process.
