Outline
Food safety issues are one of the current focuses of social concern in China. Lean meat powder is a type of drug that can promote lean meat growth in animals and improve the meat-to-feed ratio. The residue of lean meat powder in animal-derived foods poses a serious threat to consumer health, so the development of rapid and sensitive detection technologies is vital importance. Quantum dots, as a new type of nanomaterial, have shown broad application prospects in the field of food analysis due to their unique optical and electrical properties. This paper reviewed the latest application progress of rapid detection technologies in the detection of lean meat powder residues from 2 aspects: Quantum dots and detection methods. It mainly introduced the basic structure and significant characteristics of quantum dots, focused on the specific application of quantum dots in the detection of ractopamine residues, systematically elaborated on the research status of 3 mainstream analytical techniques (fluorescence analysis technology based on the fluorescence characteristics of quantum dots, immunoassay technology combining the specificity of antigen-antibody reactions and electrochemical analysis technology that enhanced sensitivity by modifying electrodes with quantum dots), summarized the challenges faced by quantum dot sensing technology in current research and looked forward to its future development directions. This article aims to provide valuable references for the development of new, highly sensitive, rapid and portable detection technology for lean meat powder.
