Abstract: Odor fingerprint technology is defined as a technology to analyze the volatile compounds by sensors, chromatography and mass spectrometry combined with multivariate statistical analysis for characterizing sample information. This technology is widely studied and applied in foods. In this paper, odor fingerprint technology is briefly introduced, which includes electronic nose, gas chromatography-mass spectrometry and data analysis. Meanwhile, application of odor fingerprint technology in the detection of meat quality and safety is reviewed. Moreover, its application in meat freshness test, flavor test, and microbial detection are also summarized. Furthermore, current problems and developmental perspectives of this technology in the detection of meat quality and safety are also discussed, which will provide theoretical references for quality and safety control of meat products.

Key words: meat, quality and safety, odor fingerprint technology, electronic nose, gas chromatography-mass spectrometry, detection
