Throughout the year, lychees, the delicious tropical fruit, are now available regardless of the season or region! During a guest appearance on the "Guangdong Voice Hotline" program, Liang Qinru, the Deputy Director-general of the Department of Science and Technology of Guangdong Province, revealed on the 7th that the Guangdong Academy of Agricultural Sciences has successfully developed an advanced ultra-low temperature freezing technique, effectively addressing the bottleneck issue in traditional lychee preservation methods. This breakthrough overcomes the challenges of maintaining color and preventing rapid quality deterioration that was commonly associated with traditional freezing methods for lychees.

Lychee, a delicacy from southern China, has always been beloved for its exquisite taste. However, its preservation has been a challenge for farmers and businesses alike, with even refrigeration only extending freshness for 3 to 5 days.

Liang Qinru mentioned that around June last year, they utilized ultra-low temperature freezing technology to preserve two to three hundred tons of freshly picked lychees. These are now gradually being released into the market. Upon thawing, their color remains vibrant, and their taste is still delightful.

The key to this preservation technique lies in rapidly pre-cooling the freshly picked lychees, reducing bacteria and maintaining color, precise packaging, rapid freezing (at -35°C or below), and frozen storage, all of which maximize cell protection, enabling year-round storage.

Upon thawing, the lychees retain their vibrant color and translucent flesh and maintain over 90% of their nutritional quality, meeting consumers' demand for fresh lychees throughout the year.

Hu Shengchun, the Director of the Division of Agriculture and Rural Affairs of the Guangdong Science and Technology Department, introduced that last year's frozen lychee products are already retailing on major e-commerce platforms, and consumer acceptance of this new product is extremely high. On some platforms, 400 grams of lychees sell for over 80 yuan. It is reported that this year's technological advancements are expected to preserve over 2,000 tons of fresh lychees.

全年荔枝“自由”！广东200多吨荔枝“冻眠”十月新鲜如初

一年四季、天南地北，均能食用到美味的荔枝啦！广东省科技厅副厅长梁勤儒7日作客“广东民声热线”节目时透露，目前，广东省农科院加工所已成功突破超低温冻眠锁鲜技术，解决了传统冷冻荔枝护色难、品质劣变快的瓶颈问题。

荔枝是岭南珍馐，因味道鲜美深受大家喜爱。但其保鲜难题一直困扰果农和企业，就算用冰箱冷藏，最多保存3～5天。

梁勤儒表示，去年6月左右，运用超低温冻眠锁鲜技术，保存了二三百吨新鲜采摘的荔枝，今年陆续投放市场，解冻食用时，色泽鲜亮，口感尚佳……

此项锁鲜技术核心要点是，新鲜采摘的荔枝，立即进行快速预冷、减菌护色、精准包装、速冻锁鲜（零下35℃或以下）和冻藏保鲜等一系列处理，最大程度保护细胞组织，使其能够实现周年储存。

解冻后，冻眠荔枝色泽如新鲜荔枝般鲜红、果肉依旧晶莹剔透、营养品质能保持九成以上，满足消费者四季享用新鲜荔枝的需求。

广东省科技厅农业农村处处长胡胜春介绍，去年生产的冻眠荔枝产品，目前已经在一些主要电商平台上展开零售，根据企业反馈，消费者对这一新产品的认可度极高。有的平台上，400克荔枝售价80多元。据悉，今年技术力量预计可保鲜2000吨以上的新鲜荔枝。
