Thesis-PhD
The present investigation was carried out at Post-Harvest Laboratory of the Department of Horticulture, College of Agriculture, Govind Ballabh Pant University of Agriculture and Technology, Pantnagar during December 2007 and December 2008. Prior to the application of post harvest treatments, fruits were sorted out for uniformity of size, quality, colour and blemished and diseased fruits were discarded. The experiment consisted of three factors viz. packaging material (newspaper wrapped fruits), storage (0, 3, 6, 9 and 12 days) and chemicals (calcium nitrate 0.5% and 1%, calcium chloride 1% and %2, calcium sulphate 0.5%, 1% and control) with three replications in factorial completely randomized design (C.R.D.). Finding of the present investigation revealed that newspaper wrapped fruits treated with calcium chloride 1% had minimum reduction in fruit size (length and breadth), fruit weight, volume and specific gravity. Value of TSS, acidity, reducing sugar, non reducing sugar, total sugar, TSS : acid ratio and sugar:acid ratio were found highest in wrapped fruit treated with calcium chloride 1% at 6th day of storage. On the basis of organoleptic evaluation highest acceptability was found at 3rd day of storage and minimum in 12th day of storage. |
