Fluorescent probe and fluorescent label for real-time, lossless and visual monitoring of freshness of meat food as well as preparation method and application of fluorescent probe and fluorescent label

The invention discloses a fluorescent probe and a fluorescent label for real-time, lossless and visual monitoring of freshness of meat products as well as a preparation method and application of the fluorescent probe and the fluorescent label. The fluorescent probe HBT-Bz with a structural formula of # imgabs0 is simple in structure and simple and convenient to synthesize; an HBT fluorophore with an ESIPT property and an AIE effect is adopted as a parent, a benzoxazole ester group is adopted as an amine compound recognition group, and a fluorescence opening type probe after amine recognition is designed and synthesized; the fluorescent probe HBT-Bz is quick and sensitive in response to amine compounds, the detection limit is as low as 5.1 ppm, and the fluorescent probe HBT-Bz can be used for manufacturing a solid fluorescence sensor for detecting volatile amine compounds. The fluorescent probe disclosed by the invention is simple in synthesis route, capable of identifying various volatile amines and low in de
