Resumo: | The current study was carried out to evaluate the effects of gamma irradiation on the epiphytic microflora and ripening process of the green Dwarf Cavendish bananas harvested at the three-quarter stage of the maturity. The mature green bananas were irradiated using Cobalt-60 as the source of irradiation at different dosages of 0.5, 0.75 and 1.0 kGy. The mean life of both the experimental and control group of fruits was analyzed under ambient conditions. For all the treatments the microbial potential, the decay percent and the ripening behavior of the fruits were recorded. Results revealed that the applied radiation doses reduced the decay incidence, delayed ripening process and greatly inhibit the microbial growth (total bacterial and fungal count) thereby enhancing the shelf life of bananas. Irradiation dose of 1.0 kGy was found to be the most effective dose to positively maintain the stored bananas under ambient conditions. The mean life of bananas was extended by 14 days. The identification of the enteric bacteriaeaceae through API 20 E strips revealed the presence of Shigella sonnie on the fruit surface along with Escherichia coli and a nonfermentor spp. The dominant spoilage causing fungi identified were Aspergillus niger, Aspergillus flavus, Collotrichum musae, Fusarium oxysporum,Mucor spp, Lasiodiplodia theobromea and Rhizopus stolonifer. |

As bananas verdes maduros foram irradiadas usando Cobalto-60 como fonte de irradiação a diferentes dosagens de 0,5, 0,75 e 1,0 kGy. A vida média de ambos os grupos experimental e de controlo de frutas foi analisada sob as condições ambientes. Para todos os tratamentos a potenciais microbiana, o percentual decadência e do comportamento do amadurecimento dos frutos foram recorded.Results revelou que as doses de radiação aplicadas reduziu a incidência de podridões, atrasou processo de amadurecimento e inibir significativamente o crescimento microbiano (contagem de bactérias e fungos total), assim aumentar a vida de prateleira das bananas. dose de irradiação de 1,0 kGy foi encontrada como sendo a dose mais eficaz para manter positivamente as bananas armazenada sob condições ambientes. A vida média de bananas foi prorrogado por 14 dias. A identificação do bacteriaeaceae entérico através de API 20 E tiras revelou a presença de Shigella sonnie sobre a superfície do fruto, juntamente com Escherichia coli e um nonfermentor spp. A deterioração dominante causando fungos identificados foram Aspergillus niger, Aspergillus flavus, Collotrichum musae, Fusarium oxysporum, Mucor spp, Lasiodiplodia theobromea e Rhizopus stolonifer.EDUFU2017-02-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3358510.14393/BJ-v33n1a2017-33585Bioscience Journal ; Vol. 33 No. 1 (2017): Jan./Feb.; 57-65Bioscience Journal ; v. 33 n. 1 (2017): Jan./Feb.; 57-651981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/33585/19787Pakistan; ContemporaryCopyright (c) 2017 Roheena Abdullah, Hina Qaiser, Adeen Farooq, Afshan Kaleem, Mehwish Iqtedar, Mahwish Aftab, Shagufta Nazhttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAbdullah, RoheenaQaiser, HinaFarooq, AdeenKaleem, AfshanIqtedar, MehwishAftab, MahwishNaz, Shagufta2022-02-16T12:36:32Zoai:ojs.www.seer.ufu.br:article/33585Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-16T12:36:32Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
