京东七鲜鸡蛋“卷”出新高度！24小时蛋场到门店，上架后只卖1天

Core Viewpoint - JD Seven Fresh Supermarket has launched the "24-hour egg" initiative, ensuring eggs are delivered from the farm to the store within 24 hours, addressing consumer demands for safety and freshness [1][3]. Group 1: Freshness and Quality Control - The "24-hour egg" project establishes a comprehensive freshness preservation system from production to consumer, emphasizing quality through selected egg sources, strict quality control, and efficient delivery [3]. - Each "24-hour egg" comes from selected farms, fed with high-quality natural grain, with corn making up 60% of the feed [3]. - Before being sold, eggs undergo over ten quality control processes, including drug residue testing, UV disinfection, crack detection, and weight grading, ensuring high standards [5]. Group 2: Innovation in Freshness Standards - JD Seven Fresh Supermarket has introduced the "half-life value" detection into its quality control process, setting a standard for eggs to reach AA grade (half-life value ≥ 80) before being sold, replacing subjective freshness assessments with objective data [5]. - The supermarket previously launched the "7-day fresh egg" initiative, which sold eggs within seven days of production, receiving positive consumer feedback and contributing to category growth [7]. Group 3: Broader Freshness Initiatives - JD Seven Fresh Supermarket has also introduced other fresh products like "24-hour vegetables" and "24-hour strawberries," establishing a time-based freshness preservation system across various categories [9]. - The company's efforts reflect a commitment to enhancing quality and consumer experience in the fresh food industry, ensuring that freshness is a reliable expectation rather than a matter of chance [10].
