Modulation of shelf life and postharvest quality of pear cv. ?Bartlett? during post cold ambient storage after cacl2 treatments.

Response of ‘Bartlett’ pears to various post-harvest CaCl2 treatments under cold storage (2°C ± 1°C with 95% ± 2% RH) conditions and periodic shelf life periods under ambient conditions (24 ± 3ºC; 68 ± 5 % RH), was recorded as changes in some important quality parameters. The fruits were dipped in 10, 20, 30 and 40 g kg-1 CaCl2 for 10, 20 and 30 min, air dried and were packed in Corrugated Fiber Board (CFB) boxes (29 × 23 × 14 cm; L × B × H). Fruits treated with 30 and 40 g kg-1 CaCl2 for 30 min recorded maximum firmness, soluble solids, titratable acidity, ascorbic acid, total phenols and calcium content with minimum spoilage, weight loss, Pectin Methyl Esterase (PME) and Polygalacturonase (PG) activity with highest scores for all the sensory parameters. The treatment effect was compared by Duncan’s new multiple range test which revealed some significant differences during shelf life periods under ambient conditions while, the post-hoc analysis by Tukey’s test showed significant differences among the sensory parameters.
