Author(s): Rocky Thokchom and Goutam Mandal
Abstract: To evaluate the influence of various postharvest treatments on the chemical characteristics of mango cv. Langra, the present laboratory investigation was carried during 2016-17. Disease and bruises free, fresh fruits of uniform size, shape and colour were harvested at physiological mature stage and were given various postharvest treatment of sodium hypochlorite (NaOCl: 100, 150, 200ppm), 6-benzyladenine (BA: 50, 100, 150ppm) and hot water (52 to 55o C) for 5, 10 and 15 minutes. The fruits were subjected to air dried and kept in 5 ply corrugated boxes (5% ventilation) with newspaper lining and stored in ambient conditions. The fruits were evaluated after 3, 6, 9 and 12 days of storage. Total soluble solids (TSS) and sugars content of the fruits increased steadily up to 9 days and thereafter declined gradually whereas, sugar acid ratio (SAR) increased linearly during storage. Titratable acidity and ascorbic acid content gradually decreased linearly whereas, beta carotene content of fruits increased linearly during storage. Fruits treated with BA @ 100ppm and HWT for 5 minutes significantly maintained higher TSS, sugars and antioxidants content of the fruits and remained acceptable up to 12 days under ambient storage conditions.
