“…Because the trace amounts of starch in the flesh of papayas could not account for the accumulation of soluble sugars, it is possible to speculate that some mechanisms of cell wall disassembly (NoGUEIRA et al, 2012;RAZALI et al, 2013) could provide a source of carbon for sugar synthesis during ripening, including sucrose. The similar profiles for glucose and fructose could be an indication that those sugars come from the accumulated sucrose, especially by the action of invertases in fully ripe fruits (PAULL et al, 2011). The intermittent sucrose level increase in 1-MCP treated fruit would also be in agreement with this idea.…”

abstract-The market demand for tropical fruits has been growing steadily over the past two decades and global papaya production has grown significantly over the last few years. This sector, however, suffers greatly from postharvest losses due to reduced quantity and quality of fruits between harvest and consumption. The use of ethylene inhibitors after harvest could improve the final quality of the fruit to satisfy the consumer and also minimize waste. The physiological and biochemical responses of 'Solo' papayas treated with the ethylene inhibitor 1-methylcyclopropene (1-MCP) to extend storage shelf life and maintain quality during long-term storage are deeply discussed in this study. Papaya fruits arrived at Cranfield University (CU) and received a 24 h 1-MCP, being stored at 20 ºC for 10 days. The ethylene inhibitor 1-MCP application significantly delayed 'Solo' papaya ripeness on fruit storage by reducing respiration rate and ethylene production. There was a delay from 7 days in fruit firmness loss and the retention of green peel colour was increased. Inhibition of ethylene perception by 1-MCP did not prevent the accumulation of sugars and the mean values were similar and higher than those found for control fruits, which are possibly due to the lower reaction speed, leading to a higher accumulation.

No entanto, esse setor sofre muito com as perdas pós-colheita devido à reduzida quantidade e qualidade dos frutos entre a colheita e o consumo. A utilização de inibidores de etileno após a colheita poderia melhorar a qualidade final do fruto para satisfazer o consumidor e também minimizar o desperdício. As respostas fisiológicas e bioquímicas de mamões 'Solo' tratados com o inibidor de etileno 1-metilciclopropeno (1-MCP) para prolongar a vida útil e manter a qualidade durante o armazenamento a longo prazo são detalhadamente discutidas neste estudo. os frutos chegaram à Universidade de Cranfield (UC) e receberam tratamento com 1-MCP por 24 h, sendo armazenados a 20 ºC durante 10 dias. A aplicação do inibidor de etileno 1-MCP retardou significativamente o amadurecimento de mamões 'Solo' no armazenamento dos frutos, reduzindo a taxa de respiração e a produção de etileno. Houve um atraso de 7 dias na perda de firmeza e a retenção da cor verde da casca dos frutos foi aumentada. A inibição da percepção de etileno pelo 1-MCP não impediu o acúmulo de açúcares e os valores médios foram semelhantes e superiores aos encontrados para as frutas do tratamento controle, que são possivelmente devido à menor velocidade de reação, levando a um maior acúmulo. termos para indexação:Carica papaya L., qualidade, desperdício, 1-MCP, frutos tropicais.ISSn 0100-2945 http://dx
