Food quality detection method, device and system based on optical analysis

The invention relates to the technical field of optical test analysis, in particular to a food quality detection method, device and system based on optical analysis, and the method comprises the following steps: calculating the peak characteristic of each Raman peak by using the data characteristics of a food spectrum curve; the wave crest interference degree of each Raman peak is obtained by combining the symmetry condition of the Raman peaks; calculating a deviation factor of a Raman peak and a peak offset of the Raman peak in combination with the detected temperature data; further constructing a deviation parameter of the Raman peak by using the temperature difference of the plurality of samples before and after detection and the peak offset of the Raman peak; and correcting the food spectrum curve through the offset parameter to obtain new spectrum data, and finally obtaining a food quality detection result of the sample. According to the method, the influence of the food heat effect caused by laser on sp
