Abstract: To investigate the impact of different calcium treatments and storage intervals on quality of peach cv. Shan-e-Punjab, a research was conducted at postharvest Laboratory, Division of Fruit Science SKUAST J, during the year 2014–2015. Statistical design used in this experiment was completely Randomized Design (CRD) with factorial arrangement repeated three times. The peach fruits (cv. Shan-e-Punjab) were harvested at colour break stage from peach orchard Udhewala SKUAST-J. The fruits were dipped in 0, 2 4 and 6% CaCl2 solution for 10 ± 5 min and transferred to cold storage having 3+2 °C with relative humidity of 80–85%. The application of post harvest cacl2 treatments and storage intervals significantly influenced the fruit quality of peach fruit. Minimum PLW (10.09%) was observed in fruits treated with 6% CaCl2. Fruit firmness (12.73 lb/inch2) TSS (13.33 °Brix), sugars (3.45 mg/100g) were increased with the advancement of storage period while as it was also able to maintain specific gravity (1.125) and Titratable acidity (0.67%) of peach fruits. Results showed that two and four percent calcium chloride treated fruits have little improvement while fruits treated with 6% calcium chloride were found to be most acceptable as per physico-chemical analyses and over all sensory acceptability result
