Infrared spectroscopy and outer product analysis for quantification of fat, nitrogen, and moisture of cocoa powder
Original language description
The combination of the near IR (NIR) and Fourier-transform IR (FTIR) absorbance spectra (1100-2500 nm and 4000-600 cm-1) of 100 cocoa powder samples was used to build calibration models for the determination of the content of fat, nitrogen, and moisture.The samples that comprised the dataset had an average component of 13.51% of fat, 3.77% nitrogen, and 3.98% moisture. The fat content ranged from 2.42 to 22.00%, the nitrogen from 0.88 to 4.48%, and moisture from 1.60 to 7.80%. For NIR, the relative root mean square error of cross-validation (RMSECV) was 7.0% (R 2 = 0.96) for fat, 1.7% (R 2 = 0.98) for nitrogen, and 5.2% (R 2 = 0.94) for moisture. For FTIR, the relative RMSECV was 10.4% (R 2 = 0.94) for fat and 3.9% (R 2 = 0.95) for nitrogen. However,for moisture, it was not possible to build a calibration model with suitable predictability. The combination of the NIR and FTIR domains (data fusion) by outer product analysis PLS1 allowed to predict these parameters and to characterize
