英文摘要:

      The extremely active small molecule formaldehyde is hazardous to the environment and can harm a person’s health permanently. The fluorescent probe method has benefits like straightforward setup, simple operation, high sensitivity, and excellent selectivity. It also has application advantages in areas like biological imaging and in vitro detection. Fluorescence probe methods, such as organic small molecule fluorescence probes, nano-fluorescence probes, and metal-organic framework probes, have seen constant attention and rapid development in the field of food testing, especially in light of the growing demand for rapid detection. These methods provide a platform for trace and rapid detection for formaldehyde. From the perspective of reaction mechanism and structure, this paper introduced and discussed the application progress of fluorescence probe method in the detection of formaldehyde in food in recent years from three aspects: Organic small molecule fluorescence probe, nano-fluorescence probe and metal-organic framework fluorescence probe, and summarized the characteristics and application effects of different types of fluorescence probe methods, providing new perspectives and considerations for the continuous optimization of fluorescence probe method in the field of food rapid detection.
