This experiment was carried out in the laboratory of Rural Development Tuki Association, Charikot, Dolakha, Nepal to study the shelf life and physio-chemical parameters of banana. The design of the experiment was completely randomized design (CRD) with 7 treatments and 3 replications with 7 destructive and 5 non-destructive samples. Samples were kept under different packaging materials. The treatments included as control, unperforated bag, perforated bag, unperforated bag with KMnO4, perforated bag with KMnO4, unperforated bag treated with CaCl2, perforated bag treated with CaCl2. The data were collected from the destructive and non-destructive sample in 2 days’ interval and MS-EXCEL and R-STUDIO was used for the data analysis. The highest physiological weight loss of banana was in control (23.33%)and lowest in unperforated polybag (0.66%), unperforated polybag with CaCl2 (0.73%), unperforated polybag with KMnO4 (1.53%) in 12 days after treatment. The highest shelf life of banana was in unperforated bags with KMnO4 (19 days) while the lowest shelf life was observed in control (9 days). The highest pulp to peel ratio was observed in control (2.23) while the lowest pulp to peel ratio was in unperforated bags with KMnO4 (1.46). The pH showed insignificant result and similarly TSS showed insignificant result till 6 DAT while control showed highest (14) and lowest was found in unperforated polybag with KMnO4 (9.33) and unperforated polybag (9.33) at 12 days after treatment. Thus, unperforated polybag with KMnO4 could be used to enhance post-harvest life of banana.
