University of Agricultural Sciences, Bengaluru
University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

The experiment was carried out to find the effect of different packages and storage temperatures for enhancing shelf life of Elakki banana fruits. Many methods are available for fruit storage such as cold storage, controlled atmosphere storage, evaporative cooling systems etc. Recently, modified atmosphere (MA) storage is getting more popular for its desirable effects. The principle is extendjng the storage life by altering the storage atmosphere around the commodity and slowing down the metabolic dpening processes without affecting the quality of lhe conm10dity. Recently long term storage of vegetables has been achieved by using silicone membnme systems (Gairepy et al., 1998; 1986 Raghavan et al., 1982). It is desirable to try and sec whether the Elakki banana fruits can be stored bcnelicially in Lhc moc.lilicThesisItem Open Access STUDIES ON PACKAGING AND STORAGE OF OSMOTICALLY DEHYDRATED AONLA (Emblica officinalis L.) SEGMENTS(University of Agricultural Sciences, Bangalore, 2010-07-15) SUMITHA, N.; TIWARI, R. B.Indian gooseberry (Emblica officinalis L.), an important fruit crop, is being grown on commercial scale in different parts of India. There is a great demand for aonla fruits and its products owing to their nutritional, medicinal properties and delicacy. The osmodried aonla has tendency to become brown during storage. The present investigation aimed at finding out the suitable packing material and storage condition for maintaining the colour and quality of osmo-air dried aonla segments during storage. Different kinds of packages viz. 200 gauge high density polyethylene (HDPE) bag, punnet and polyethylene terpthalate (PET) jar were used to pack the osmo-air dried aonla segments. Packed samples were stored at room temperature (20-300C, 53-76% RH) under light and dark conditions, and at low temperature (150C, 55-60% RH) for six months. Product was analyzed for changes in their chemical constituents and organoleptic qualities at two months intervals up to the end of storage period. Studies revealed that samples packed in PET jar and stored at low temperature retained highest ascorbic acid and acidity. Furthermore, there was an increase in reducing sugar, total sugars, and partial reduction in non-reducing sugar content in aonla segments during storage. Significantly low non-enzymatic browning was recorded in case of PET jar stored under low temperature. Highest overall acceptability was observed in samples packed in PET jar and stored under low temperature. In contrast, lowest sensory score was recorded in case of samples stored at room temperature under dark condition. Thus, it can be concluded that, packing samples in PET jar and storing them under low temperature is a promising way to improve the storage life of osmo-air dried aonla segments.ThesisItem Open Access DEVELOPMENT OF PROTO-TYPE FOR DECORTICATION OF CUDDAPAH ALMOND (Buchanania axillaris (Desr.) T.P.Ramamoorthy)(University of Agricultural Sciences, Bangalore, 2010-09-15) JADHAV VINAYAK, SHANKAR; Ramkumar, M. V.Buchanania is a tree borne oil nut belonging to the family Anacardiaceae. Historically, this plant has long been used in India and neighbouring regions. The fruit is considered as one of the most delicious wild fruits and the kernels are eaten raw or in roasted form as a substitute for almond. The kernel contains oil (51.8 per cent) which is sweet and has a mild pleasant aroma. It is used as a substitute for olive and almond oils in confectionaries and pharmaceutical preparations. Decortication is the main process in the post harvest processing of Buchanania. Graded and ungraded nuts are the two main categories in Buchanania pod. Therefore, a study was under taken to develop a decorticator for Buchanania nuts at the Division of Agricultural Engineering, University of Agricultural Sciences, Bangalore. During processing the ungraded nuts gave maximum output compared to graded nuts. However, the kernel damage was maximum in ungraded nuts. Three pre-treatments were imposed for softening of shell of Buchanania fruits. The damage to the kernel during decortication of Buchanania nuts did not affect the commercial value of the product. A decortication machine was developed to address the important operation of separating kernels from nuts. The prototype machine was tested for both category of nuts and for different machine clearances (7.5 and 8 mm) at different drum speeds (150 and 300rpm), and at 7 and 9 per cent moisture content and different pre-treatments (sand, steam and cold water). The maximum output of 60.31kg/h was recorded in the ungraded nuts at 7.5 per cent moisture content. Among the two clearances (7.5 and 8mm) studied, 8mm clearance found to be the best considering the damages to kernel and decortication efficiency. The maximum efficiency was 98.5% in the graded nuts at 7 per cent moisture content after three passes of the nut. The kernel recovery in sand treatment was higher compared to cold, water and steam. The cost of the developed prototype of Buchanania decorticating machine was Rs. 8400 and the processing cost of converting 1 kg of Buchanania nuts into kernel was only Re.0.51 compared to Rs.10.16 in the traditional processing. The cost-benefit Ratio was 1:1.75.ThesisItem Open Access STUDIES ON SHELF LIFE EXTENSION OF SOLO PAPAYA (Carica papaya. L) FRUIT(University of Agricultural Sciences GKVK, Bangalore, 2008-07-20) RAVI, H. N.; Eshwarappa, H.An experiment was conducted in the laboratories of AICRP on Post Harvest Technology, UAS, GKVK, Bangalore, during the year 2007-2008. The experiment was carried out to find the effect of different packages and storage temperatures for enhancing shelf life of Solo papaya fruits. Many methods are available for fruit storage such as cold storage, controlled atmosphere storage, evaporative cooling systems etc. Recently, modified atmosphere (MA) storage is getting more popular for its desirable effects. The principle is extending the storage life by altering the storage atmosphere around the commodity and slowing down the metabolic ripening processes without affecting the quality of the commodity. Recently long term storage of vegetables has been achieved by using silicone membrane systems (Gairepy et al., 1998; 1986 Raghavan et al., 1982). It is desirable to try and see whether the Solo papaya fruits can be stored beneficially in the modified atmosphere created by the silicone membrane and diffusion channel systems. Fruits were packed in two different packages like silicone membrane with different window areas in airtight PET jars and diffusion channel system with different lengths and diameters in PET jars at ambient temperature for evaluation. PLW and gas composition inside the package were determined and then quality parameters were estimated immediately after removing from MAP. Finally best two packages each from, silicone membrane system and diffusion channel system were selected and fruits in these packages were stored in two different temperatures (Ambient, and 15oC) to find the effect of different packages and storage temperatures for enhancing shelf-life. The shelf life of Solo papaya fruits under ambient and refrigeration temperature in case of silicone membrane and diffusion channel systems it was 25 days compared to control which could be kept well for only 7 days under ambient temperature.
