Comportamento pós-colheita de mamões Formosa 'Tainung 01' acondicionados em diferentes embalagens para o transporte

Abstract

1 CARLOS EDUARDO MAGALHÃES DOS SANTOSRESUMO-O objetivo deste trabalho foi avaliar a comportamento pós-colheita de mamões do grupo Formosa híbrido 'Tainung 01', submetidos a diferentes formas de acondicionamento para o transporte rodoviário, desde o local da produção até o mercado atacadista. Foram utilizados mamões colhidos nos estádios 1 (até 10% da área superficial da casca com cor amarela) e 3 (25 a 40% da área superficial da casca com cor amarela), acondicionados sob diferentes formas: a granel, em caixas de madeira, em caixas de papelão ondulado e em caixas plásticas forradas com plástico-bolha (controle), e transportados a Viçosa-MG, distante 750 km da produção, onde os frutos foram avaliados. Após seleção e novo acondicionamento, os frutos foram armazenamento a 24,5 ± 2ºC por 8 dias, com amostragens a cada 2 dias, para avaliação de índice de cor da casca, perda de massa fresca, taxa respiratória, firmeza da polpa e o índice de injúrias mecânicas. Os resultados evidenciaram os efeitos depreciativos das injúrias mecânicas na qualidade final do mamão, sendo que o transporte de frutos a granel, em relação ao controle, promoveu alterações na qualidade pós-colheita dos frutos, com aumento do índice de cor da casca, redução na firmeza da polpa, elevada perda de massa fresca e taxa respiratória, e maiores percentagens de área da casca injuriada, nos dois estádios de coloração estudados (1,14 e 1,21%, respectivamente). As caixas de papelão ondulado e caixas plásticas forradas com plástico-bolha mantiveram baixa a percentagem de área injuriada em relação aos transportados a granel, constituindo-se em alternativas promissoras na manutenção da qualidade pós-colheita de mamão Formosa destinado ao mercado interno. Termos para indexação: Carica papaya, pós-colheita, injúria mecânica. POST HARVEST BEHAVIOR OF PAPAYA FORMOSA 'TAINUNG 01' CONDITIONED IN DIFFERENT PACKINGS FOR TRANSPORTATIONABSTRACT-The aim of this study was to evaluate the post harvest behavior of papaya from the hybrid group Formosa 'TAINUNG 01' stored in different packages for road transportation, from the farm to the wholesale market. It was used papaya picked in the stages 1 (up to 10% of the colored yellow skin superficial area) and 3 (25 to 40% of the colored yellow skin superficial area), packed in different ways: in bulk, in wooden boxes, in wavy cardboard boxes and in plastic boxes covered internally with bubble-wrap (control), and then transported to Viçosa/MG, 750 km away from the production, where the fruits were evaluated. After selection and new packaging, the fruits were stored for 24,5 ± 2ºC for eight days with samplings every two days, to evaluate the skin color index, fresh mass loss, respiration rate, pulp firmness and the mechanical injuries index. The results showed the depreciative effects of the mechanical injuries on the final quality of the papaya, as the transportation of fruits in bulk, in regard to control, caused alterations on the fruit post harvest quality, with increase of skin color index, decrease of pulp firmness, high fr...

“…On the 15th of storage day, it was estimated a loss of fresh mass in the magnitude of up to 25.49% (control), it is twenty times higher than the tolerable limit (5%) recommended by Santos et al (2008) to commercial conditions. However, for the hermetic-bag, perforated-bag, and plastic film, losses may be considered acceptable on every evaluation day, according to the overall treatment average.…”

Evaluation of the Papayas maturation degree by electrical impedance

“…Similar results were found by Oliveira Junior et al (2006) with Papaya 'Sunrise alone'. It was observed an increase in the fresh mass loss during storage and according to Santos et al (2008) a loss over 5 % of it is sufficient to depreciate Papaya fruit. In this work, that level (5%) of LFW occurred after 2 d of harvest, presenting a considerable statistical growth during storage, corroborating with the corresponding level described by Dias et al (2011).…”

Evaluating the Performance of Coconut Fiber and Wood Straw as Cushioning Materials to Reduce Injuries of Papaya and Mango during Transportation

“…With respect to the instrumental color of the studied areas, the abrasions on the fruit surfaces were not sufficiently aggressive to cause enzymatic browning; there was an increase in luminosity during the whole storage period. In a study with Formosa papayas [22], this behavior was related to mechanical injuries, which can accelerate the metabolism of the fruit and promote a change in skin color.…”
