Cool chain management is the preferred technology to extend the postharvest life of horticultural produce, but with rising energy costs and community pressure to reduce greenhouse gas emissions, there is a need to use less energy-intensive technologies. Minimising the level of ethylene around horticultural produce inhibits ripening and senescence and therefore has the potential to reduce the use of refrigeration. The long-distance transport of bananas within Australia and from Central America to Europe is used as a case study to show that the need for refrigeration could be reduced if the appropriate concentrations of ethylene were maintained around fruit during transit. Data are also presented to show a similar benefit of ethylene control with green beans, as well as another study showing that apples treated with the ethylene action inhibitor 1-methylcyclopropene could be stored at a higher temperature without loss of quality to the consumer. The range of technologies available to manage ethylene levels is discussed.
冷链管理是延长园艺产品采后寿命的首选技术，但随着能源成本上升以及社区对减少温室气体排放的压力，有必要采用能源密集度较低的技术。将园艺产品周围的乙烯水平降至最低可抑制其成熟和衰老，因此有可能减少制冷的使用。以澳大利亚境内以及从中美洲到欧洲的香蕉长途运输为例，说明如果在运输过程中水果周围保持适当的乙烯浓度，就可以减少制冷需求。还提供了数据表明控制乙烯对绿豆也有类似的益处，另外一项研究表明，用乙烯作用抑制剂1-甲基环丙烯处理过的苹果可以在较高温度下储存而不会降低对消费者的品质。文中讨论了可用于控制乙烯水平的一系列技术。
