Abstract：The freshness of meat and meat products can be evaluated by the content of metabolites produced during their spoilage of the product. Biogenic amines are one of the substances produced during the spoilage of meat and meat products, which is an important indicator for monitoring the freshness of food. The traditional detection methods for biogenic amines are tedious, time-consuming and laborious. It is of great practical significance and scientific value to establish a fast and convenient detection method. The biogenic amine fluorescence response membrane is a solid-state optical sensor composed of a fluorescence material and a sensing membrane, which can detect biogenic amine in real time by the fluorescent color change of the sensing film. In recent years, it is widely used for detecting the freshness of meat and meat products because of its high sensitivity, low cost, simple operation and fast response time. In this paper, the formation and classification of biogenic amines in meat and meat products and the harm of biogenic amines to the human body are briefly summarized with a focus on the application of fluorescence response membranes constructed based on different fluorescence response principles in the freshness monitoring of meat and meat products.
