Abstract:
An experiment was conducted during 2018-19 in the Department of Fruit Science and Horticulture Technology, Odisha University of Agriculture and Technology, Bhubaneswar to determine the effect of chemicals and growth regulator in different concentrations such as CaCl₂ 1%, CaCl₂ 1.5%, Ca (NO₃)₂ 1%, Ca (NO₃)₂ 1.5%, GA₃ 50 ppm, GA₃ 100 ppm followed by perforated polythene packaging and polythene packaging without any chemical on physico-chemical property and shelf life of jamun fruits cv. CISH J 42. This experiment was carried out in ambient condition. From this experiment it was concluded that fruits treated with 1.5% CaCl₂ and kept in perforated polyethylene bag, maintained desirable physico-chemical parameters viz. total soluble solid (9.100%), reducing sugar (2.907%), total sugar (3.080%), titrable acidity (0.261%), sugar-acid ratio (13.793) as well as the desirable organoleptic quality which make them acceptable up to 6 days as compared to control.
