Abstract

Post-harvest handling of banana is a crucial activity to get good quality fruit  to the consumers. A post-harvest study on ripening of banana was carried out  at Regional Agriculture Research Station, Khajura during winter season of  2005 to find out the effect of different materials in ripening of banana and  study about shelf-life period. Dipping fruits in Kripone 2.56 ml per liter of  water (ethephone 1000 ppm) for five minutes was found effective for banana  ripening. Those fruits treated with ethephone 1000 ppm started to soften in  three days and became ready to consume in five days with shelf-life of eight  days. Fruits treated with 'Asuro' (Adhatoda vesica) started to become soft in  five days where as fruits treated with 'Koiralo' (Bahunia veriagata) became  soft in four days. By using these indigenous plant materials, we can prolong  shelf-life of fruit by 2-3 days more than the Kripone-treated fruits. Use of  ripe banana fruit also found effective to hasten ripening the banana with  excellent taste. However, the shelf-life was relatively short (8 days). It is  difficult to ripen the banana in winter without using any ripening materials.  In untreated control, only 33% fruits started to become soft after 7-9 days of  storage and were ready to consume in nine days. Rest 66% fruits were  remain as such up to 11 days then after fruit started uneven softening ie some  portion became soft and other portion remained hard. After 14 days fruits  became black without softening and got spoiled. Overall percent weight loss  was found 6.0 to 10.7 from initial to end of shelf-life period.
