Abstract

An experiment was carried out to investigate the effect of different packaging materials on shelf life and quality of banana fruits at Postharvest laboratory of Uttar Banga Krishi Viswavidyalaya, Pundibari, West Bengal. The experimental treatments were Un-perforated & perforated polyethylene bag and news paper wrapping in combination with KMnO4 & Wax coating along with control. The experiment was laid out in a complete randomized design (CRD) with three replications. Fruits treated with KMnO4 + wax coating kept in unperforated polythene cover under ambient conditions was recorded highest green-life (17.31 days), yellow-life (7.62 days) and shelf-life (24.93 days) when compared to control. The titrable acidity was also highest in the same treatment on 3rd day (0.94 and 0.99) degraded up to (0.26 and 0.29 %) on 24th day whereas in control it was recorded (0.68 and 0.63) on 3rd day and degraded to (0.36 and 0.35%) on 12th day only. Similarly, the sugar acid ratio was also best in case of fruits treated with KMnO4 + wax coating kept in unperforated polythene cover (T3) and KMnO4 + wax coating kept in perforated polythene cover when compared to control.

Conclusion

Under ambient conditions and without any post-harvest storage treatments Grand Naine fruits could be stored up to 12 days. However, using different post-harvest packaging treatments can extended shelf lifeup to 24 days along with improved quality and increased fruit shelf life (green + yellow life) during storage through increased sugar acid ratio, thus it is recommended to create a modified atmospheric condition of the storage environment by packaging the fruits in polyethylene bags with or without perforations but fortifying the bagging with potassium permanganate and wax coating of the stored fruits.
