Core Viewpoint - The innovative freezing technology developed by the research team at the Guangdong Academy of Agricultural Sciences is transforming the lychee industry, addressing long-standing preservation challenges and enhancing product offerings, thereby increasing market reach and profitability for farmers [1][2][3]. Group 1: Technological Innovations - The breakthrough in ultra-low temperature freezing technology allows lychees to be preserved for over a year without significant loss of quality, maintaining over 80% of their nutritional content [2]. - The research team has developed a comprehensive technical system that includes a no-ice preservation system for e-commerce, reducing post-harvest loss by 15%, and an air transport preservation system that extends shelf life by 30% for exports [3]. - A new production line for frozen lychees is expected to reach an output of 2,000 tons, utilizing a "shared factory + shared technology" model to lower costs for farmers and cooperatives [3]. Group 2: Product Development - The team is also focusing on deep processing of lychees, creating new products such as lychee ice cream, which incorporates over 40% fermented lychee juice, enhancing flavor and health benefits [4]. - Innovative techniques have been established to produce dietary fiber from lychee pomace, achieving a yield of up to 58.55%, and new lychee rice wine products have been developed, gaining popularity among consumers [4]. Group 3: Future Outlook - The research team aims to continue optimizing technologies and developing market-driven products to expand the global reach of Guangdong lychees and improve the livelihoods of local farmers [5].

Core Viewpoint - Guangdong Province has developed a comprehensive "Lychee Preservation Processing Tree" to enhance the preservation and processing of lychee, aiming to establish a modern industrial chain from farm to table [2][16]. Preservation Technology - The "Lychee Preservation Processing Tree" outlines the entire chain of preservation technology and industrial development paths, showcasing a complete system from basic preservation techniques to innovative applications [3][4]. - The preservation time for lychee varieties such as Jinggang Hongnuo, Bingli, and Xianjin Feng has been extended from 6 days to 1 month through integrated preservation technologies [17]. - The application of ultra-low temperature freezing technology enables year-round sales and global distribution of lychee [18]. Processing Innovations - Leading companies like Guangzhou Pharmaceutical Group have established the first fully automated lychee juice production line in China, with an annual processing capacity exceeding 100,000 tons, resulting in over 30 high-value-added products such as fermented lychee juice and lychee cosmetics [20]. - The lychee industry is focusing on the utilization of by-products, with high-concentration polyphenol extracts from lychee pulp entering the cosmetics supply chain, and activated carbon products from lychee seeds achieving an annual production capacity of 5,000 tons [24][25]. Infrastructure Development - Guangdong has constructed over 1,700 cold storage facilities for agricultural products, promoting the development of cold chain logistics to address preservation and transportation challenges [21][22]. - The integration of temperature and humidity monitoring systems in cold chain transport equipment allows for traceable data throughout the lychee distribution process, enhancing consumer confidence [22][23].
