Food quality and safety has been a great public concern all over the globe and reliable sensors or monitoring systems has become a prerequisite to affirm quality of various food commodities, especially highly perishable foods, such as seafood, pork, beef, lamb and chicken. Food freshness chemosensors is an emerging sensing technology in the field of food industrial research and development. Although the application of chemosensors is evidently on the move and concurrently lacking commercial viability, it has tremendous potential to empower onsite monitoring of food quality and safety in the food processing industry. This review aims to (a) elaborate different classes of CPs and CPs nanocomposite based chemosensors; (b) sensor systems with special focus on innovative conjugated polymer (CPs) chemical sensors for food freshness detection; and (c) applications of highly sensitive and selective (CPs) nanocomposite based chemosensors with Active/Intelligent technologies for meat and seafood spoilage detection Via colorimetric (naked eye detection) and fluorometric "turn - on/off" response, providing new pathways of CPs based nanocomposite chemosensor-application in the food industry. Thus, this review illustrates the potential scope of such intelligent sensor systems in food spoilage detection for commercial viability, resulting as a very simple, cost-efficient, consumer approved and other multipurpose tool.

食品质量和安全一直是全球范围内引起公众极大关注的问题，可靠的传感器或监控系统已成为确认各种食品尤其是易腐烂食品（例如海鲜，猪肉，牛肉，羊肉和鸡肉）质量的先决条件。食品新鲜度化学传感器是食品工业研发领域中的新兴传感技术。尽管化学传感器的应用显然正在发展中，并且同时缺乏商业可行性，但它具有巨大的潜力，可以在食品加工行业中对食品质量和安全性进行现场监控。这篇综述旨在（a）阐述不同类别的CP和基于纳米复合材料的CPs化学传感器；（b）传感器系统特别关注用于食品新鲜度检测的创新型共轭聚合物（CPs）化学传感器；（c）具有主动/智能技术的基于高灵敏度和选择性（CPs）纳米复合物的化学传感器在肉类和海产品变质检测中的应用，通过比色法（裸眼检测）和荧光“开/关”响应，提供了CP的新途径纳米复合化学传感器在食品工业中的应用。因此，本综述说明了这种智能传感器系统在食品腐败检测中的商业可行性的潜在范围，这是一种非常简单，具有成本效益，获得消费者认可的多功能工具。为基于CPs的纳米复合化学传感器在食品工业中的应用提供了新途径。因此，本综述说明了这种智能传感器系统在食品腐败检测中的商业可行性的潜在范围，这是一种非常简单，具有成本效益，获得消费者认可的多功能工具。为基于CPs的纳米复合化学传感器在食品工业中的应用提供了新途径。因此，本综述说明了这种智能传感器系统在食品腐败检测中的商业可行性的潜在范围，这是一种非常简单，具有成本效益，获得消费者认可的多功能工具。
