Recent advances in fluorescent and colorimetric sensing for volatile organic amines and biogenic amines in food

Abstract

Volatile organic amines and biogenic amines produced by the amino acid degradation can undeniably affect the food quality and safety, and thus causes serious health problems. It is of great urgency to exploit reliable and sensitive detection methods for amines to ensure food safety and public health. The fluorescent and colorimetric sensors offer simple and robust means to monitor amines with high sensitivity and selectivity, quick response, facile operation and low cost. Herein, we briefly review the past five years’ progress in fluorescent and colorimetric sensing for monitoring organic and biogenic amines in food. The architectures of sensing materials ranging from small molecules to frameworks to polymers or self-assembly materials have been highlighted. Moreover, the main challenges and perspective of various sensing materials are presented to inspire further research and development. In the end, the development trend of new sensing materials and devices for real-time monitoring of food quality is also forecasted. This review is expected spur more research interest in design of novel amine sensing materials for future application transformation research.
