别把“陈粮”与“陈化粮”混为一谈

Core Viewpoint - The article emphasizes that reserve grain, even if it is older, is safe for consumption and meets national food safety standards, distinguishing it from "aged grain" which is unsafe [1][2]. Group 1: Grain Quality and Safety - Reserve grain is defined as grain stored for over one year, which may lose freshness but still meets quality and nutritional standards, making it safe for food processing or animal feed [1][2]. - "Aged grain" refers to grain that has deteriorated due to poor storage conditions or excessive storage time, making it unsafe for consumption and only suitable for non-food uses [1][2]. - Modern storage techniques significantly reduce the risk of reserve grain becoming aged grain, ensuring that quality is maintained [1][2]. Group 2: Historical Context and Improvements - The concept of "aged grain" emerged in the late 1990s due to inadequate storage mechanisms and poor quality control, with reserve grain storage rates dropping to around 60% [2]. - Since the early 2000s, reforms in grain circulation and the establishment of a scientific reserve grain rotation mechanism have improved storage rates to over 95% [2]. - The introduction of modern storage facilities and technologies has eliminated the "aged grain" issue, enhancing overall grain quality [2]. Group 3: Quality Control Measures - Strict quality control measures are implemented during the grain storage process, including comprehensive testing for moisture, impurities, and safety indicators [3]. - A dynamic monitoring system is in place, utilizing sensors and AI technology to track grain conditions and detect potential issues [3]. - Each batch of grain is assigned an "electronic ID" for traceability, ensuring that the entire supply chain is transparent and accountable [3]. Group 4: Grain Distribution and Utilization - The rotation of reserve grain is managed through various channels, including competitive sales on grain trading platforms and targeted supply to key food processing enterprises [4]. - Grain nearing its expiration date is repurposed for animal feed or industrial use after thorough testing, promoting resource efficiency and food safety [4]. - The systematic rotation of new and old grain ensures that reserve quantities are accurate and quality is maintained, allowing for effective national response during emergencies [4].
