The invention belongs to the technical field of meat product quality detection, and particularly relates to a method for quickly identifying cold fresh beef and frozen beef based on an electrochemicalphase spectrum. The method for identifying cold fresh beef and frozen beef comprises the following specific steps: preparing beef samples and numbering; acquiring the electrochemical phase spectrum data of the beef samples by a CHI660E electrochemical workstation; reducing the dimension of the acquired electrochemical phase spectrum data by a principal component analysis method; building an identification model of cold fresh beef and frozen beef based on the dimension-reduced phase spectrum data by a chemometrics method; acquiring the phase spectrum data of unknown beef samples to be detected, and predicting the storage way of the unknown beef samples to be detected by the built rapid identification model. The identification method disclosed by the invention needs short time, and the costof a detection device is low. When the number of principal components is eight during identification of cold fresh beef and frozen beef, the recognition rates of a training set and a test set reach 100 percent, the recognition accuracy is high, and rapid identification can be realized.
