A method for detecting the quality of cell culture fluid based on Raman spectral measurement. The method comprises the following steps: collecting cell culture fluid; collecting, processing and analyzing a Raman spectral signal; measuring an original Raman spectral signal of a metabolite in the cell culture fluid using a Raman spectra technique; determining whether the original Raman spectral signal is qualified, and carrying out data signal processing on the qualified original Raman spectral signal to obtain analyzable signals; and then carrying out difference statistical analysis on the analyzable signals to obtain difference signals; carrying out modeling using the difference signals; classifying the difference signals using a support vector machine; and distinguishing the spectral signals of normal and abnormal cell culture fluid to obtain a quality result of the cell culture fluid. Difference signals in cell culture fluid are detected by means of Raman spectra to detect the quality of the cell culture fluid, thereby achieving the purpose of non-invasive evaluation of a cell growth state; and the method is convenient, effective and low-cost, and can achieve large-scale industrialization and streamlining.
