ABSTRACT

The present investigation was undertaken to study the effect of various postharvest treatments on extension of shelf-life of Kesar mango fruits. For this purpose, the mango fruits were harvested at proper stage of maturity and subjected to various postharvest dip treatments such as calcium chlOride (2%), waxing (6%) and fungicides viz., Bavistin (0.1%) and Captan (0.2%) either alone or in combination. The mango fruits were then packed in corrugated fibre board box and stored in three storage environments viz., at room temperature (28.12 to 36.18°C temperature and 46.18 to 71.25% RH), in cool chamber (21.47 to 27.10°C temperature and 91 to 95% RH) and cool store (10°C temperature and 90 to 95% RH). It was found that the shelf life of mango fruits couId be extended upto 65 days when treated with a combination of CaCl 2 (2%) + wax (6%) + Bavistin (0.1%) and stored in cool store, upto 35 days when stored in cool chamber and upto 24 days when stored at room temperature. On the contrary, the shelf life of untreated fruit was found to be hardly 18 days at room temperature. It was also observed that this treatment recorded lower physiological loss in weight and high organoleptic score when stored in cool store and cool chamber as compared to room temperature storage. The untreated (control) fruits were found to be infected with Colletotrichum gloeosporioldes, Diploidia natalensis and Rhizopus sp.
