Core Viewpoint - The article discusses the innovative preservation technologies for Lianzhou Choy Sum, aiming to reduce spoilage and enhance efficiency in the agricultural sector, particularly focusing on the challenges faced in maintaining the freshness of this vegetable variety [2][10][16]. Group 1: Industry Overview - Lianzhou Choy Sum is a significant vegetable in Guangdong, with a projected comprehensive output value of 2 billion yuan in 2024 [9]. - The planting area for Lingnan Choy Sum is expected to reach 360,000 acres, with a production volume of 497,000 tons in 2024 [13]. - High spoilage rates pose a major challenge, with losses estimated at 20 yuan per unit, primarily due to the delicate nature of leafy vegetables [11][14]. Group 2: Preservation Challenges - Leafy vegetables like Choy Sum are prone to yellowing, wilting, and nutrient loss post-harvest, with a shelf life of less than three days under normal storage conditions [12]. - The industry faces three main issues: difficulty in maintaining freshness, safety risks, and challenges in antibacterial and pest control [14][15]. Group 3: Innovative Solutions - The association has introduced new preservation technologies, including carbon quantum dot antibacterial preservation, temperature-responsive release technology, and COFS gas control technology [17][18]. - These technologies aim to create a micro-ecological environment that induces dormancy in vegetables, achieving long-term preservation [19]. - A trial with 2,000 pounds of Lianzhou Choy Sum demonstrated that the new materials and technologies could maintain a crisp texture after 27 days of storage, with water content over 95% and chlorophyll retention above 90% [20][21]. Group 4: Future Plans - The association plans to collaborate with local bases in Lianzhou to promote the application of these preservation materials and technologies [25]. - The goal is to support the development of a "100 billion" level modern agricultural industry in Lianzhou, enhancing farmers' income and prosperity [27].
