The growing interest in food quality and safety requires the development of sensitive and reliable methods of analysis as well as technology for freshness preservation and food quality. This review describes the status of chemical and biological sensors for food monitoring and smart packaging. Sensing designs and their analytical features for measuring freshness markers, allergens, pathogens, adulterants and toxicants are discussed with example of applications. Their potential implementation in smart packaging could facilitate food-status monitoring, reduce food waste, extend shelf-life, and improve overall food quality. However, most sensors are still in the development stage and need significant work before implementation in real-world applications. Issues like sensitivity, selectivity, robustness, and safety of the sensing materials due to potential contact or migration in food need to be established. The current development status of these technologies, along with a discussion of the challenges and opportunities for future research, are discussed.
人们对食品质量和安全的关注度不断提高，这就需要开发灵敏且可靠的分析方法以及用于保鲜和食品质量控制的技术。本综述介绍了用于食品监测和智能包装的化学和生物传感器的现状。文中结合应用实例讨论了用于检测新鲜度指标、过敏原、病原体、掺假物和有毒物质的传感设计及其分析特性。它们在智能包装中的潜在应用有助于食品状态监测、减少食物浪费、延长保质期并提高整体食品质量。然而，大多数传感器仍处于研发阶段，在实际应用之前还需要大量工作。由于传感材料可能与食品接触或迁移，因此需要确定其灵敏度、选择性、稳健性和安全性等问题。本文讨论了这些技术的当前发展状况，并探讨了未来研究面临的挑战和机遇。
