Rapid Discrimination of Cheese Products Based on Probabilistic Neural Network and Raman Spectroscopy

Figure 2

Quality fluctuation individual value of brand XX (a), brand YY (b), and brand ZZ (c) and moving range of brand XX (d), brand YY (e), and brand ZZ (f) based on Raman peak intensities (at 1760 cm⁻¹), respectively. UCL = upper control limit; LCL = lower control limit; MR = the average value of moving range control chart. The UCL, LCL, and MR were calculated based on the Raman data of brand XX.
