Abstract
This work was aimed to investigate the effect of 1-methylcyclopropene (1-MCP), ethylene absorber (EA), ozone alone or in combination on melon quality during storage. Ethylene production, respiration rates, acoustic firmness, surface color, chilling injury, and disease severity of melon were determined. 1-MCP treated fruits and non 1-MCP treated fruits were stored with sachets of ethylene absorber containing KMnO4 or ozone at 0.1 ppm/h during 10 days at 5 °C and subsequent 4 days at 20 °C. Melons treated with 1-MCP were firmer than the rest of the samples during storage. In addition, 1-MCP reduced the yellowing of melon rind compared to other treatments. The combination of 1-MCP and EA did not offer any additional effect in comparison with 1-MCP alone. There was no significant difference between fruits stored with ethylene absorber, ozone and control samples. Ozone treatment during cold storage decreased disease severity, however, fruits exposed to ozone had more serious decay throughout storage at 20 °C, probably due to the unclean air in the chamber.
這項工作旨在研究1-甲基環丙烯(1-MCP)，乙烯吸收劑(EA)，單獨或組合使用的臭氧對存儲期間瓜品質的影響。確定了乙烯的產生，呼吸頻率，聲音硬度，表面顏色，冷害和甜瓜的嚴重程度。1-MCP處理過的水果和未1-MCP處理過的水果在5天的10天和20天的4天中，以0.1 ppm / h的速度將含有小袋的含KMnO4或臭氧的乙烯吸收劑儲存。在儲存過程中，用1-MCP處理的甜瓜比其余樣品更堅硬。此外，與其他處理相比，1-MCP減少了瓜皮的黃變。與1-MCP單獨使用相比，1-MCP和EA的組合未提供任何其他效果。用乙烯吸收劑儲藏的水果之間沒有顯著差異，臭氧和對照樣品。冷藏過程中的臭氧處理降低了疾病的嚴重性，但是，暴露于臭氧中的水果在20°C的整個存儲過程中都有更嚴重的腐爛現象，這可能是由于箱內空氣不干凈所致。
