Core Viewpoint - The article discusses the challenges of preserving tropical fruits in Guangdong's Lingnan region and highlights the innovative technologies developed by the Guangdong Academy of Agricultural Sciences to enhance fruit processing and extend shelf life, particularly for lychee [1][2]. Group 1: Preservation Technology - The "frozen dormancy" technology allows lychee to maintain its fresh taste and appearance for months, overcoming traditional preservation methods that lead to rapid spoilage [2][3]. - This technology involves rapid pre-cooling, sterilization, and precise packaging, followed by immersion in a liquid medium at -40 degrees Celsius to achieve effective preservation [2][3]. - The result is that lychee can be stored for over a year, enabling year-round sales and reducing seasonal market pressures [3]. Group 2: Processing Innovations - The research institute has developed a "super high pressure+" non-thermal sterilization technology that effectively kills bacteria without damaging the fruit's flavor and nutritional value [4]. - Innovations in juice processing, including the use of DMDC for sterilization and self-absorbing fermentation technology, have improved the quality and production speed of fruit vinegar and wine [4][5]. - A new energy-efficient juice concentration technology has been created to minimize common issues like color darkening and sedimentation during processing [5]. Group 3: Market Impact - The advancements in processing technology have led to a significant increase in the quality of fruit products, allowing for the development of various new products such as juice drinks and sparkling water [6]. - The research institute's support has enabled local farmers to sell their lychee more effectively, increasing their income and reducing waste during peak harvest seasons [6]. - The institute has provided technical support to multiple agricultural parks and has expanded its assistance to other regions for various fruit industries, enhancing overall agricultural productivity [6].
