Resumo: | The objective of this experiment was to evaluate the gaseous composition and quality maintenance of ‘Gala’ apples, stored within polyethylene (PE) bags of different thickness combined with ethylene absorption, during refrigerated transport. The treatments evaluated were combinations of two PE film thickness [high density polyethylene (HDPE) of 7µm and low density polyethylene (LDPE) of 20µm] with different number of ethylene absorbents (potassium permanganate) per bag (0, 1 and 3). Each experimental unity contained 18kg of fruits previously stored at 0.5°C during 1 month. After this period fruits were wrapped with the films and packed in cadboard boxes, being submitted during 15 days at 4°C, simulating refrigerated transport plus 3 days of shelf-life at 20°C. Lower levels of O2 and ethylene and higher of CO2 were observed within LDPE bags of 20µm than in HDPE bags of 7µm. Moreover, the use of ethylene absorbents reduced the ethylene level within bags. However, due to the low storage time (15 days) and fruit ripeness at the packaging, the reduction of ethylene levels did not show significant effect on fruit quality. |

Os tratamentos foram obtidos pela combinação de duas espessuras de filmes de polietileno [polietileno de alta densidade (PEAD) de 7mm e polietileno de baixa densidade (PEBD) de 20mm] e de diferentes quantidades de sachês absorvedores de etileno (permanganato de potássio) por embalagem (0, 1 e 3 sachês). Cada unidade experimental constituiu-se de 18kg de frutos, que haviam sido previamente armazenados a 0,5°C por um mês. Após este período, os frutos foram embalados nos filmes, acondicionados em caixas de papelão e submetidos durante 15 dias a 4ºC e mais três dias a 20ºC. Verificou-se que o uso de filmes de PEBD de 20µm permitiu menores concentrações de O2 e de etileno e maiores de CO2, em relação ao filme de 7µm, no interior das embalagens. Além disso, o uso de sachês absorvedores de etileno diminuiu a concentração de etileno. No entanto, devido ao curto período de armazenamento (15 dias) e à maturação dos frutos no momento da embalagem, a redução dos níveis de etileno não apresentou efeito significativo nos atributos qualitativos dos frutos.UEL2006-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/246010.5433/1679-0359.2006v27n3p423Semina: Ciências Agrárias; Vol. 27 No. 3 (2006); 423-428Semina: Ciências Agrárias; v. 27 n. 3 (2006); 423-4281679-03591676-546Xreponame:Semina.
