中文摘要:

      近年来食品质量安全问题频发, 如何有效保障食品质量安全已经成为目前公众最关心的热点问题之一。由于食品在生产加工过程中极易受生化污染物的污染, 因此, 针对食品中污染物的检测方法和技术的研究已成为当前保障食品质量安全的重要前提。目前, 传统的食品污染物检测方法由于操作复杂、仪器设备成本高等无法进行现场的实时监测。生物传感器作为一种新兴检测技术, 由于其操作简单、可重复性好、极易实现现场检测等优点, 已被广泛应用到食品质量安全检测领域。因此, 本文阐述了生物传感器的类型、概念与发展概况, 分析了生物传感器的工作原理, 比较了其与传统检测方法的优缺点, 并深入探讨了生物传感器在检测食品成分、品质、添加剂、微生物和病毒、农药和兽药残留以及生物毒性等方面的应用和研究进展, 最后基于当前的研究对未来的研究方向进行了展望, 以期为生物传感器在食品质量安全检测领域的进一步研究和推广应用提供理论基础。

英文摘要:

      With the frequent occurrence of food quality and safety problems in recent years, how to effectively safeguard food quality and safety has become one of the hot issues of greatest concern to the public at present. Since food is highly susceptible to biochemical contamination during production and processing. Therefore, the research on the detection methods and techniques of contaminants in food will become an important prerequisite to ensure the quality and safety of food. At present, the traditional detection methods are unable to carry out on-site and real-time monitoring due to the complexity of operation and the high cost of instruments and equipment. However, as an emerging detection technology, biosensors have been widely used food quality and safety inspection in the field due to their advantages of simple operation, good repeatability, and extreme ease of on-site detection. Here, this paper described the biosensor types, concepts, and development overview. Meanwhile, the device and working principle of biosensors were analyzed. this paper also compared the advantages and disadvantages of biosensors with traditional detection methods. On this basis, this paper delved into the applications and researched progress of biosensors in detecting food composition, quality, additives, microorganisms and viruses, pesticide and veterinary drug residues, and biological toxicity. Finally, this paper prospected the future research direction with a view to providing a theoretical basis for further research and popularization of biosensors of food quality and safety detection in the field.
