荔枝是成熟于盛夏又最不耐贮藏的果品之一,果实含水量食糖量很高,采后的生理、生化变化十分剧烈,极易褐变、腐烂,一般只能存放2～3天。为延长荔枝的销售期限及扩大销售地区,我们从1982年开始对荔枝进行了气调为主的贮藏技术研究,经过多次筛选,采用采后果品处理并充氮低温批量贮藏25天后检查结果,好果率达97.6％,失重率均小于3％,货架寿命达两天以上,达到了国家科委的保鲜标准。
Litchi is mature in midsummer one of the most intolerant of fruit storage, fruit moisture content of sugar is very high, postharvest physiological and biochemical changes are very intense, easily browning, decay, the general can only be stored for 2 to 3 days. In order to extend the sales period of lychee and to expand the sales area, we conducted a research on the storage of litchi mainly by atmosphere in 1982. After several screening, post-harvest fruit processing and nitrogen storage at low temperature for 25 days, Good fruit rate of 97.6%, weight loss rate of less than 3%, shelf life of more than two days, reached the preservation standards of the State Science and Technology Commission.
