| Abstract: |
| Harmful components in dairy products include pesticide residues， veterinary drug residues， heavy metal residues， microorganisms， harmful additives and other noxious substances introduced from the packaging or transportation. These harmful components are harmful to people's health. However， it is a challenge to achieve accurate and rapid analysis of dairy products due to the diversity and substrates complexity of dairy samples， different structures and properties of various harmful substances， as well as their low content levels. Thus， to develop rapid and efficient sample preparation techniques， as well as accurate and sensitive analysis or detection methods is inevitable. In this paper， the progress in the preparation methods for dairy products in recent years is reviewed， including solid phase （micro）extraction， liquid phase （micro）extraction and immunoaffinity chromatography， etc. Meanwhile， this article introduces the progress of various analytical methods for these hazardous substances， such as chromatography， atomic spectroscopy， electrochemical analysis， biological immunoassay， molecular spectroscopy， etc. Furthermore， the advantages and disadvantages of laboratory analytical methods and on－site rapid detection methods are also compared， and the characteristics of these technologies are summarized. Finally， their future development trends are forecasted in the paper， anticipating to provide a support for the quality and safety supervision of dairy products in China. |
