Resumo: This study aimed to evaluate some changes in the metabolism of papaya fruits submitted to damage by impact, abrasion and compression. Injuries were caused in two areas of 15 cm2 each; in diametrically opposite positions in the equatorial region of ‘Improved Sunrise Solo Line 72/12’ papaya fruits in ripening stage 3 (fruits with 25-40% of yellow skin). After damage, fruits were stored at 15 ± 1 °C and 85 ± 5% RH, and samples were taken at intervals of two days to evaluate skin color index, incidence of diseases, loss of fresh weight, leak of solutes, pulp firmness, soluble solids content and pectinmethylesterase and polygalacturonase activities. The respiratory rate was measured at intervals of 4, 8, 12, 24, 48 and 72 hours after damage. The results show the suppressive effects of mechanical damage on the final quality and also on fruit shelf life. Mechanically damaged fruits anticipated ripening, with skin color indexes higher than control fruits. Abrasion was the damage that caused more dramatic effects, showing, at the end of the study period, loss of fresh weight and leak of solutes of 27% and 18.7%, respectively, higher than control fruits. In addition, fruits submitted to this type of damage have higher respiratory rate and also higher rot incidence. The pectinmethylesterase and polygalacturonase activity was not consistently changed in relation to damage. Similarly, there was no difference in soluble solids content.

Os danos foram provocados em duas áreas de 15 cm2 cada, em posições diametralmente opostas, na região equatorial de mamões ‘Improved Sunrise Solo Line 72/12’ no estádio 3 de amadurecimento (frutos com 25 a 40% da área superficial da casca amarela). Após os danos, os frutos foram armazenados a 15 ± 1 ºC e 85 ± 5% de UR, sendo as amostragens feitas em intervalos de dois dias para avaliação de índice de cor da casca, incidência de podridões, perda de massa fresca, vazamento de solutos, firmeza da polpa, teor de sólidos solúveis e atividade das enzimas pectinametilesterase e poligalacturonase. A taxa respiratória foi avaliada nos intervalos de 4, 8, 12, 24, 48 e 72 horas após os danos. Os resultados evidenciaram os efeitos depreciativos dos danos mecânicos na qualidade final e também no tempo de vida de prateleira dos mamões. Os frutos mecanicamente danificados anteciparam o amadurecimento, apresentando índices de cor da casca maiores do que os dos frutos controle. O dano por abrasão foi o que provocou efeitos mais drásticos, por apresentar, no final do período avaliado, perda de massa média e vazamento de solutos 27% e 18,7%, respectivamente, maiores do que nos frutos controle. Além disso, os frutos submetidos a esse dano apresentaram uma maior taxa respiratória e também maior incidência de podridões. A atividade das enzimas pectinametilesterase e poligalacturonase não foi alterada de forma consistente em função dos danos. Da mesma forma, não se observou diferenças no teor de sólidos solúveis.Revista Brasileira de Fruticultura2022-08-08T18:24:37Z2022-08-08T18:24:37Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1806-9967http://dx.doi.org/10.1590/0100-29452016095https://locus.ufv.br//handle/123456789/29575engv. 38, n. 04, e-095, p. 1-11, jul./aug. 2016Salomão, Luiz Carlos ChamhumCecon, Paulo RobertoAquino, César FernandesLins, Leila Cristina Rosa DeBraga, Luciano Ribeiroinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T07:11:08Zoai:locus.ufv.br:123456789/29575Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T07:11:08LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
