The present study was conducted to investigate the effect of various post-harvest treatments on ripening, shelf-life and quality of Banganapalli mango. The various post-harvest treatments included were fruit dip in hot water, AgNO3, MH, NAA, CaNO3, wax emulsion, storage with KMnO4 with Silica gel. Treated fruit were stored under zero energy cool chamber (ZECC) and under room temperature. The fruit treated with Bavistin (0.1%) and stored under ZECC and cold storage conditions delayed the ripening to maximum extent. The potassium permanganate-silica get treatment and ZECC storage was most effective in delaying the spoilage of the fruit. The chemical composition namely TSS, TSS/acid ratio, reducing non-reducing and total sugars were in general low in treated fruits. However, total titrable acidity and ascorbic acid content were higher. Further, the fruits dipped in 6% was emulsion and stored under ZECC conditions recorded greater shelf-life compared to other post-harvest treatments.
