经济日报文章：别把“陈粮”与“陈化粮”混为一谈

Core Viewpoint - The article emphasizes that reserve grain, even if stored for over a year, is safe for consumption and meets national food safety standards, distinguishing it from "aged grain" which is unsafe due to poor storage conditions [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 improper storage or excessive time in storage, leading to issues like mold and contamination, and is unsuitable for consumption [1][2]. - Modern storage techniques have significantly reduced the risk of reserve grain becoming aged grain, with a storage suitability rate increasing from 60% to over 95% [2]. Group 2: Storage and Rotation Mechanism - The grain rotation mechanism has been improved, with modern storage facilities and technologies ensuring better quality control and monitoring of stored grain [2][3]. - Different types of grains have varying rotation cycles, with rice typically rotated every 2-3 years, wheat every 3-5 years, and corn every 2-3 years, with annual rotation quantities controlled at 20% to 30% of total reserves [2]. Group 3: Quality Control Measures - Strict quality control measures are in place for both incoming and outgoing grain, including comprehensive testing for moisture, impurities, and safety indicators [3]. - A dynamic monitoring system is established within storage facilities, utilizing sensors and AI technology to track grain conditions and detect potential issues [3]. Group 4: Distribution of Reserve Grain - The rotation of reserve grain is managed through various channels, ensuring that quality grain reaches consumers while minimizing waste [4]. - Quality grain is sold through competitive bidding on trading platforms or directed to key food processing enterprises, while near-expiry grain is repurposed for animal feed or industrial use [4].
