The aim of this study was using chemical and irradiation processing of banana fruit, to increase the storage period. The chemical treatment (Topsen 70% WP) with rate of 80g/100 liter water, then fruit soaked in the solution about for 10 minutes. Even as, irradiation treatments were used four doses as 2.1, 4.2, 6.3 and 8.4 krad, at Laboratory of Irradiation Middle Eastern Regional Radioisotopes Center for the Arab Countries, Dokki, Giza, Egypt. The obtained results were as follows: (1) The fruit decay time was increased in about 48h that is the banana fruit was extended shelf life fruit in 48h using chemical treatment compare in untreated fruits (control). (2) The fruit mass losses were 1.35 and 2.33g for chemical treatment and un-treated fruits. Therefore, the mass losses of chemical treated fruits were reducer in about 0.98g than un-treated fruits (control). (3) The highest fruit decay and mass losses percentages were obtained with irradiation treatments 2.1 krad at cold storage 192h. In the meantime, the lowest fruit decay was recorded 6.3 krad at cold storage 240h. (4) All treatments were effective for increasing shelf-life as compared with an untreated fruit after 240 h of cold storage. An increases fruit shelf life 72, 96, 120 and 120 were observed in irradiation doses of 2.1, 4.2, 6.3 and 8.4 krad compare in fruit chemical treatment, which were 120; 144; 168 and 168h compare in untreated fruits (control).
