The work aims to study the application progress of meat freshness detection methods in cold chain logistics, and help develop food freshness detection methods to meet the market demand. According to the principle of meat spoilage, the effects of cold chain logistics on the freshness of food were analyzed. The working principle of current meat freshness detection technology was expounded. And the research status of meat freshness detection technology was introduced. In recent years, the detection technology of meat freshness is becoming more intelligent and the detection precision is improved, but there are still some problems such as the high cost of the detection technology and the inability to effectively monitor the sales process. As a relatively low-cost and easy-to-process detection technology, intelligent label has a great room for development
