The invention provides a pepper pungency degree rapid detection method based on specific parenchyma cell thickness and application, and belongs to the technical field of pepper quality detection. According to the method, the pungency degree can be rapidly calculated by taking the radial thickness of the specific parenchymal cells on the inner side of the peel of the fresh red chili fruit as a morphological marker, measuring the thickness through sampling, vibration slicing and microscopic observation and substituting the thickness into a linear regression equation y = 25.751 x-3078.4, x is the cell thickness [mu] m, and y is a predicted Scovier index SHU.
