According to the method, the red pepper to be detected can be quickly pre-classified, and compared with traditional physical and chemical detection or sensory evaluation, the hemp degree classification speed and accuracy are greatly improved; if the detection result is dispute, a more precise instrument can be used for detection; the early-stage electronic tongue is quickly classified, so that the problems of time and labor consumption and excessive sample consumption of a precise instrument can be reduced; the detection accuracy is greatly improved through the classification strategy and technology by firstly classifying the hemp degree into large classes and then classifying the hemp degree into small classes in the same large class.
