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.

    The present study entitled “Post harvest characterisation and value addition of sweet lovi-lovi (Flacourtia spp.)” was undertaken with the objectives of characterising sweet lovi-lovi accessions based on physico-chemical and nutritional attributes, to enhance shelf life through packaging and value addition. The sweet lovi-lovi accessions were collected from three centers located at Vellanikkara namely, college orchard of Department of Fruit Science, Central nursery and Regional station of National Bureau of Plant Genetic Resources. The physico-chemical characters showed significant variation among the sweet lovi-lovi accessions. The desirable post harvest qualities like high fruit weight, pulp percentage, less seed content along with highest total sugar (12.81 %), non reducing sugar (1.33 %), anthocyanin (0.04 mg 100g−1), carotenoid (582.55 mg 100g−1), iron (33.23 mg 100g−1), crude fibre (2.92 g 100g−1) and lowest tannin (0.21 mg 100g−1) was observed in Acc. 2 collected from college orchard. Hence ripe sweet lovi-lovi fruits from Acc. 2 were used for shelf life studies. Standardisation of packaging and storage requirements were done in Acc. 2 by subjecting fruits to five methods of packaging viz., packing in polythene cover (200 gauge) with ventilation, polythene cover (200 gauge) without ventilation, polypropylene punnets, polystyrene box covered with cling film, shrink wrapping in areca plate. Each package was stored in ambient, refrigerated (5 ± 2°C) and cold storage (12 ± 2°C) conditions. Shelf life of sweet lovi-lovi fruits was longer when stored under cold storage condition than fruits stored in ambient and refrigerated condition. Areca plates containing fruits wrapped with polyolefin film of 15μ thickness (T6) and fruits packed in polythene cover (200 gauge) without ventilation (T3) in cold storage were found to have longest shelf life (3 days). The physiological loss in weight (PLW %) was significantly highest and shelf life was shortest in unwrapped fruits under the three different storage conditions. The treatment T6 showed highest TSS (17.27 °Brix) and total sugar (12.73 %) after one day of storage at 12 ± 2°C. To increase the utilisation of sweet lovi-lovi fruits, value added products like wine, preserve and Ready To Serve beverage were prepared and evaluated. Among the wine prepared from five accessions, the overall acceptability was maximum for Acc. 5 (7.50). All the attributes of wine showed an increasing trend on storage and the total score raised from 58.09 to 61.77 after three months. The highest mean scores for flavour (7.54), texture (7.27), odour (7.27), taste (8.00), after taste (7.54) and overall acceptability (7.86) were recorded for Acc. 2 among the preserve prepared from five accessions of sweet lovi-lovi. During storage, the total score for organoleptic attributes increased from 58.02 to 58.47 for preserve prepared from this accession. RTS beverage prepared from Acc. 3 recorded highest mean score for appearance (7.44), colour (7.12), texture (7.44), taste (7.81), and overall acceptability (7.78). All the attributes showed a declining trend and the total score decreased from 59.09 to 55.43 after three months of storage. Thus accessions 2, 3 and 5 were found to be ideal for preparation of preserve, RTS beverage and wine respectively. The microbial population was least during the initial month and increased slightly on storage but was within the permissible limit in all the products. The results of the study indicated that sweet lovi-lovi has good nutritional potential almost similar to other minor fruits like jamun, blackberry etc. The extension of shelf life to 3 days also help in better utilization of the fruit and prospects for value addition is high for sweet lovi-lovi.
