dc.description.abstractDuring present investigations, ber fruits of variety Kaithali (shelf -life 4-5 days) at mature green stage were harvested and were analyzed for various physico-chemical and biochemical parameters during storage. PLW, TSS content and sugars (total and reducing) of ber fruits with increasing storage period while fruit firmness and tittratable acidity exhibited continuous decrease throughout storage. The oxidative stress which is indicated by H2O2 content, MDA content and LOX activity, increased significantly during storage while the activities of ROS scavenging enzymes viz. SOD, CAT, POX, PPO and GR were invariably low at the later stages during storage. ROS scavenging metabolite viz. ascorbic acid, total phenolics, total flavonoids and antioxidative activity increased upto 8 th DOS and thereafter decreased at 10 th days of storage. However β-carotene decreased continuously throughout storage period. Pretreatment of chitosan and CaCl2 delayed PLW, decreased TSS content and sugars content and retained fruit firmness and acidity significantly during storage. Fruits treated with CaCl2 (2%) and chitosan (1%) alone and in combination could help them to retain higher antioxidative activity and ROS scavenging metabolites and the combined treatment of 2% CaCl2 and 1% chitosan was the most effective in enhancing storage ability of fruits.en_US
