Method for rapidly identifying and evaluating different oxidation tastes of milk based on electronic nose

The invention belongs to the technical field of food quality monitoring, and discloses a method for rapidly identifying and evaluating different oxidation flavors of milk based on an electronic nose, and the method specifically comprises the following steps: S1, establishing reference samples of three oxidation flavors of milk; s2, electronic nose detection: respectively using metal oxide sensors on an electronic nose to detect gases emitted by the established three oxidation taste reference samples; s3, screening effective sensors of the electronic nose, analyzing and identifying the sensors useful for distinguishing the samples based on detection results of the three oxidation taste reference samples, and establishing a response diagram of the sensors of the electronic nose; s4, establishing a discrimination model and a sensory evaluation model based on the electronic nose sensor response diagram; and S5, sample testing. According to the method, reference samples of different raw materials and different oxi
