Abstract
Mango fruits of “Zibda” cv. were harvested at mature green stage from 20-years-old trees grown in a private orchard in two successive seasons of 2008-2009.The effect of post-harvest antioxidant treatments on changes of physical and chemical characteristics were studied during cold storage at 5±1°C and 80-85% RH for 30 days. Pre-storage tested fruits were soaked in vitamin C solutions at 0.5 and 1.0 gL-1 or vitamin B12 solutions at 0.5 and 1.0 mgL-1 for 12 hr. Changes on these characteristics were determined on stored fruits at 5-day-intervals.
Results of changes in the tested physical and chemical parameters almost indicated an obvious gradual decrease on fruit firmness, fruit juice vitamin C and acidity% along with fresh peel chlorophyll contents as cold storage period advanced. On the other hand, Fruit weight loss%, fruit juice TSS%, TSS/acid ratio and total sugars along with fresh peel β-carotene content were gradually increased as cold storage period advanced. The rates of such decrease or increase were differed due to the tested antioxidant treatment, concentration and parameter.
 As for changes of chilling injury incidence “CI”, the results revealed that the first observation of “CI” symptoms was at the15th day measurement and then an obvious gradual increase on calculated “CI” index of all the post-harvest treated and stored fruits till the end of cold storage period. Vitamin C treatments with either 0.5 or 1.0 gL-1 "T1" and "T2" was the best ones to calculate the fewest index values (reduce “CI” incidence).
