Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    Physico-chemical characterization of hill honey
    (CSK HPKV, Palampur, 2022-12-21) Goswamy, Yashasvini; Sharma, Surender Kumar
    The present investigation was carried out at Bee Research Station, Nagrota Bagwan of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur, District Kangra, Himachal Pradesh, India, during the year 2021-2022. In this study, sixty samples of honey were analyzed for various physico-chemical characteristics viz., pH, moisture, colour (optical density), ash content, EC, sucrose, TRS, fructose, glucose, F:G ratio, acidity, diastase activity and HMF content. The physico-chemical characteristics of honey from different locations ranged between 3.85±0.16 to 5.63±0.01 for pH, 15.57±0.08 to 25.94±0.10 per cent for moisture, 0.06±0.01 to 0.28±0.03 g/5g for ash content, 0.21±0.01 to 1.13±0.01 mS/cm for EC, 0.42±0.01 to 1.65±0.27 for optical density, 3.20±0.08 to 4.66±0.04 per cent for sucrose, 34.65±0.09 to 42.06±0.24 meq/kg for acidity, 66.95±0.62 to 70.79±0.55 per cent for TRS, 28.71±0.50 to 31.45±0.50 per cent for glucose, 36.88±0.61 to 42.26±0.10 per cent for fructose, 1.19±0.03 to 1.47±0.02 for F:G ratio, 14.00±0.54 to 17.50±0.24 DN for diastase activity and 16.33±0.66 to 20.90±1.09 mg/kg for HMF content. Among the bee species, the highest pH (5.19±0.08), sucrose (4.59±0.07%) and HMF content (20.62±0.61 mg/kg) were recorded in the honey of Apis cerana whereas higher ash content (0.23±0.01 g/5g), acidity (39.27±0.61 meq/kg), total reducing sugars (67.37±0.55%) and glucose (31.90±1.43%) were observed in the honey of Apis mellifera. The highest moisture (25.93±0.11%), electrical conductivity (0.72±0.06 mS/cm), fructose (39.07±0.44%), F:G ratio (1.40±0.02), diastase activity (17.28±0.33 DN) and optical density (1.42±0.09) were recorded in the honey of Apis dorsata. During storage, the moisture content, optical density, sucrose, acidity, glucose and HMF content increased whereas pH, TRS, fructose, F:G ratio and diastase activity decreased. Storage of honey at room temperature for six months resulted in granulation of twenty-one honey samples and fermentation in one honey sample. The physical and chemical characteristics of almost all the hill honey samples were within acceptable limits and met FSSAI criteria.
