Rapid and precise analytical tools are essential for monitoring food safety and screening of any undesirable contaminants, allergens, or pathogens, which may cause significant health risks upon consumption. Substantial developments in analytical techniques have empowered the analyses and quantitation of these contaminants. However, conventional techniques are limited by delayed analysis times, expensive and laborious sample preparation, and the necessity for highly-trained workers. Therefore, prompt advances in electrochemical biosensors have supported significant gains in quantitative detection and screening of food contaminants and showed incredible potential as a means of defying such limitations. Apart from indicating high specificity towards the target analytes, these biosensors have also addressed the challenge of food industry by providing high analytical accuracy within complex food matrices. Here, we discuss some of the recent advances in this area and analyze the role and contributions made by electrochemical biosensors in the food industry. This article also reviews the key challenges we believe biosensors need to overcome to become the industry standard.
快速而精确的分析工具对于监测食品安全以及筛查任何可能在食用时造成重大健康风险的不良污染物、过敏原或病原体至关重要。分析技术的重大发展使得对这些污染物的分析和定量成为可能。然而，传统技术存在分析时间延迟、样品制备昂贵且费力以及需要训练有素的工作人员等局限性。因此，电化学生物传感器的迅速发展在食品污染物的定量检测和筛查方面取得了显著进展，并显示出作为克服此类局限性手段的巨大潜力。除了对目标分析物具有高特异性外，这些生物传感器还通过在复杂食品基质中提供高分析准确性解决了食品工业面临的挑战。在此，我们讨论该领域的一些最新进展，并分析电化学生物传感器在食品工业中的作用和贡献。本文还回顾了我们认为生物传感器要成为行业标准需要克服的关键挑战。
