Abstract

Purpose: In Bangladesh,mango fruit supply is limited in the local market as well as for export due to its short self-life and susceptibility to post-harvest diseases. This study aimed to evaluate the effects of CaCl2 in hot water on organoleptic and biochemical characteristics of mango fruits for extension of shelf-life. Research Method: Mangoes were treated with different concentrations (0.0, 0.5, 1, 2, 3, 4 & 5 %) of CaCl2 in hot water (50°C) for 10 min and kept at 25±2°C over 12 days. Each treatment included 20 mangoes with three replications. The physiological changes were observed and biochemical characteristics of mango fruits were analyzed. Findings: Better skin color and aroma were observed at 0.5~4.0% CaCl2 and no fungal infection was found at 3~5% CaCl2 as compared with untreated control whereas taste and texture of mangoes increased significantly with the increasing concentration of CaCl2. The shelf life of treated mangoes increased 2~3 days with increasing concentration of 4~5% CaCl2 but slight skin shriveling and weight loss were observed. Higher concentration of CaCl2 treated fruits maintained higher values of moisture, ash, titratable acidity, vitamin-C, reducing sugar, starch, invertase activity whereas total soluble solid, total sugar, non-reducing sugar, total phenol, amylase, polyphenoloxidase activity decreased significantly. Limitations: In future, mechanism of CaCl2 in hot water for extending shelf life of mangoes will be elucidated using molecular approach.  Originality/Value: The treatment of 4% CaCl2 in hot water could be used to extend the shelf life of mangoes up to 2~3 days with consumer acceptance.
