中文摘要:

      青脆李因其质地清脆、风味酸甜可口、营养含量丰富而受到消费者追捧。但是采后运输过程中的青脆李生理活动、微生物污染或结构损伤均易导致果实软化、转黄、腐烂等, 严重缩短了青脆李的货架期, 损害了商品价值, 因此青脆李采后保鲜尤为重要。冷链物流是一种能够减少损耗防止污染的低温运输系统, 也是最常用的运输保藏方法, 具有较大的应用前景。本文概述了低温下青脆李腐败变质因素, 总结青脆李冷链运输相关保鲜技术, 包括果实采后处理技术如冷热处理、紫外辐照、气调保鲜等物理保鲜技术, 化学或天然试剂修饰、可食膜、涂层等化学保鲜技术, 以及冷链物流系统监控技术等, 为青脆李冷链物流保鲜技术研究提供参考。

英文摘要:

      Prunus salicina Lindl. Cv. Qingcui is sought after by consumers because of its crisp texture, sweet and sour flavor and rich nutrition content. However, the physiological activities, microbial contamination or structural damage of Prunus salicina Lindl. Cv. Qingcui during postharvest transportation can easily lead to fruit softening, yellowing, rotten, etc., which seriously shorten the shelf life of Prunus salicina Lindl. Cv. Qingcui and damage the value of the product. Therefore, it is particularly important to keep fresh after picking. Cold chain logistics is a kind of low-temperature transportation system that can reduce losses and prevent pollution. It is also the most commonly used transportation preservation method which has a large application prospect. The article outlined the factors of Prunus salicina Lindl. Cv. Qingcui’s corruption at low temperature, and summarized the relevant fresh-keeping techniques for the transportation related to the Prunus salicina Lindl. Cv. Qingcui cold chain, including the perspectives of physics, such as cold and heat treatment, ultraviolet radiation, gas preservation technologies, and the perspectives of chemistry, such as chemical or natural reagent modification, edible film, edible coating, as well as cold chain logistics system monitoring technology, etc., which is excepted to provide reference for the research on cold chain logistics preservation technology of Prunus salicina Lindl. Cv. Qingcui.
