“…According to Table 1, 1-MCP significantly reduced papayas respiratory rate (p ≤ 0.05), immediately on the 1 st day of analysis (corresponding to Day 0, after 24 h 1-MCP). Respiration can also be affected by cultivar, maturity, tissue, and storage temperature (TERRy et al, 2007). For ethylene production, 1-MCP inhibitor treatment presented lower average values compared to control treatment, even in non-significant levels.…”

“…To release 1 μL L -1 1-MCP gas, 16.30 mL warm (50 ºC) water was injected into the conical flask (CooLS et al, 2011). Gas samples were taken periodically by using 60 mL plastic syringes, and were analyzed (TERRY et al, 2007) by extraction and injection into a GC 8340 gas chromatograph (Carlo Erba Instruments, herts, UK). After 24 h of 1-MCP treatment, 5 fruits from each box were analyzed and the remaining fruits were distributed in 13 L sealed polypropylene boxes, being stored at 20 ºC for 10 days.…”

“…1, 5, 10 and 25 mL of standard solution were pipetted into 50 mL volumetric flasks, which were filled up with HPLC grade water to give final standard concentrations of 0.05; 0.25; 0.50; 1.25 and 2.5 mg L -1 (sucrose, glucose and fructose, respectively). From each standard, 1.0 mL aliquots were dispensed into HPLC vials and stored at -40 ºC until required (TERRY et al, 2007).…”

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

Application of Ethylene Scavenging Systems on Fruits and Vegetables and Their Effects on Shelf Life ABSTRACTEthylene is a naturally occurring gaseous plant growth regulator that has numerous effects on the growth, development and storage life of many fruits and vegetables. A very low amount of ethylene is enough to affect the growth, development, ripening and aging of most fruits and vegetables. Thus, ethylene is a critical factor for the shelf life of fruits and vegetables. It largely causes an increase in maturity and loss in freshness of fruits and vegetables. To restrict negative effects of ethylene on fruits and vegetables and to increase the shelf life of these products, new methods with active packaging applications have been developed. In this paper, ethylene scavenging systems as one of the active packaging systems and the effects of these systems on the quality and shelf life of fruits & vegetables are presented.Keywords: Ethylene, Fruits and vegetables, Active packaging, Ethylene scavengers GİRİŞGünümüzde sağlıklı ve dengeli beslenmenin giderek önem kazanmasıyla birlikte uzun süre taze kalan ve çabuk bozulmayan gıdalara olan tüketici talebi de artış göstermiştir. Meyve ve sebzeler karbonhidrat, yağ, protein, vitamin ve mineral içerikleriyle insan beslenmesinde önemli yeri olan gıdalardandır. Meyve ve sebzelerin ürün kalitesi üzerinde üretimlerinden hasat edilmelerine kadar olan süreç kadar, hasat edildikten sonra tüketiciye ulaşana kadar geçirdikleri süreç de oldukça etkilidir. Özellikle hasat sonrasındaki süreçte sağlıklı koşullarda muhafaza raf ömrü ve besin değerlerinin korunması bakımından önem taşımaktadır.
