Abstract

The present investigation on “Effect of polyamines, packaging materials and storage conditions on shelf life of banana (Musa paradisiaca L.) cv. Grand Naine” was conducted during June 2021 and November 2021 at the Laboratory of Postharvest Technology, Department of Horticulture, MPKV., Rahuri, Dist. Ahmednagar. The effect of polyamines, packaging materials and storage conditions on shelf life of banana cv. Grand Naine was laid out with three polyamine treatments viz., A1 - Putrescine @ 5mM, A2 - Spermine @5 µM, A3 - Spermidine@ 4 mM, four packaging materials viz., P1 -Perforated polyethylene bag, P2- Nano silver based bag, P3- KMnO4 based ethylene absorber 4g, P4 - KMnO4 based ethylene absorber6g, two different storage conditions viz., S1 -Ambient temperature and S2 - Cold storage (13°C+1). During storage, lowest physiological loss in weight (%), ripening (%), spoilage (%) and moisture content (%) recorded in treatment combination A2P4S2 i.e. spermine @ 5 µM + KMnO4 based ethylene absorber 6 g + cold storage (130C+1) at the end of storage life. From concluded that fruits treated with A2P4S2 i.e. spermine @ 5 µM + KMnO4 based ethylene absorber 6 g + cold storage (13°C+1) was found best treatment for extension of shelf life of banana. Banana is a climacteric fruit, rapid physico-chemical changes after harvest leads to deterioration and senescence. Therefore, there is a need to regulate its ripening so as to improve its shelf life.

Conclusion

From the experiment it can be concluded that polyamines, packaging materials and storage conditions improve the shelf life of banana fruits. Considering physical parameters viz., physiological loss in weight (%), ripening (%), spoilage (%) and moisture content (%) the treatment, spermine 5 µM + KMnO4 based ethylene absorber 6g + cold storage (13°C+1) was found to be best recorded highest shelf life up to 20 days in banana cv. Grand Naine at ambient conditions and 26 days under cold storage. Effect of polyamines on the health of humans can be studied before recommendation.
