Behavioral Pattern of Physicochemical Constituents of the Postharvest Mango (Mangifera indica L.) Influenced by Storage Stimuli

Md. Khairul Islam

An investigation was carried at the laboratory of the Department of Biochemistry and Molecular Biology, University of Rajshahi, Bangladesh during the period from May, 2010 to September, 2011 to study the behavioral pattern of some physicochemical constituents of the mango pulp. The experiment was comprised of two popular mango cultivars in Bangladesh (viz., Langra and Khirshapat) and six storage stimuli, namely control, paraffin coating, perforated polyethylene cover, unperforated polyethylene cover, hot water (55±1°C) and low temperature (4±1°C). The two factors experiment was assigned in randomized complete block design with tree replicates. The varieties had profound variation in terms of most of the characters studied in the laboratory condition. Initially the Langra significantly enriched a greater amount of vitamin C (151.23 mg/100 g) and titratable acidity (4.31%) and these were decreased gradually with the progress of storage period. The Khirshapat showed higher pulp pH (5.83); produced enormous amount of TSS (18.00%) and sugar (TS = 17.62%, RS = 6.51% and NRS = 11.06%) content at 12th day of storage. The pH, TSS, sugar (TS, RS and NRS) content of mango pulp was rapidly increased, whereas vitamin C and titratable acidity decreased drastically from the untreated mangoes. On the other hand, low temperature retarded the changes. The Langra using low temperature (4±1°C) exhibited lower diminishing tendency in vitamin C and titratable acidity and also using no treatment slightly increased TSS; enriched enormous amount of sugar (TS, RS and NRS). Therefore, low temperature (4±1°C) was found satisfactory for delay ripening and postharvest changes of mango in storage condition.
