摘要
目的探讨智能包装技术在食品质量监测中的应用现状,系统分析射频识别(RFID)标签、指示器型及传感器型智能包装的工作原理、功能特性,以及它们在食品贮运保鲜和新鲜度监测中的具体应用,并针对技术瓶颈提出未来的研究方向。结果RFID标签可实时监测食品包装内的温度、湿度、pH及气体成分,结合区块链技术可以显著提升供应链的追溯效率;指示器型包装通过颜色的变化可以直观地反映氧气、二氧化碳、挥发性含氮化合物等气体浓度的变化情况,其中气体指示器、新鲜度指示器和时间-温度指示器(TTI)分别针对不同变质机制提供实时监测;传感器型包装利用天然色素(如姜黄素、花色苷)的pH敏感性或气体传感器的化学电阻/电位特性,实现对食品新鲜度的无损监测。此外,生物传感器通过检测微生物污染及农药残留,进一步保障食品安全。结论智能包装技术在食品质量监测中显著展现出应用潜力,但我国相关研究仍处于起步阶段。未来需开发高精度、低成本传感器,推动与物联网、人工智能的深度融合,并研发环保可降解材料,以提升可持续性。通过技术创新和跨学科协作,智能包装有望构建智能化、信息化的食品质量监测体系,减少食品浪费,并保障消费者健康。
The work aims to explore the application status of intelligent packaging technology in food quality monitoring,systematically analyze the working principles and functional characteristics of radio frequency identification(RFID)tags,indicator-type,and sensor-type intelligent packaging,and propose future research directions addressing technical limitations.RFID tags enable real-time monitoring of temperature,humidity,pH,and gas composition in food packaging and significantly enhanced supply chain traceability when integrated with blockchain.Indicator-type packaging visually reflected gas concentration changes(e.g.,oxygen,carbon dioxide,volatile nitrogen compounds)through color variations,with gas indicators,freshness indicators,and time-temperature indicators(TTI)targeting distinct spoilage mechanisms.Sensor-type packaging utilized pH-sensitive natural pigments(e.g.,curcumin,anthocyanins)or chemiresistive/potentiometric gas sensors for non-destructive freshness monitoring.Biosensors further ensured food safety by detecting microbial contamination and pesticide residues.Intelligent packaging technology demonstrates significant potential in food quality monitoring,but the related research in China remains nascent.Future efforts should focus on developing high-precision,low-cost sensors,promoting interdisciplinary integration with IoT and AI,and advancing eco-friendly materials for sustainability.Through technological innovation and cross-disciplinary collaboration,intelligent packaging is expected to establish a smart,information-driven food quality monitoring system,reducing waste and safeguarding consumer health.
