Abstract
This study combined Fourier transform-near infrared (NIR) spectroscopy and chemometrics, to
monitor changes in peptide content during the solid-state fermentation of rapeseed meal. A NIR
calibration model was established by performing spectral scanning on 81 samples and using
interval partial least squares. The results showed that coefficient of determination (R2) and root
mean square error of cross-validation could achieve 0.9441 and 0.654 g/L for polypeptide content.
Furthermore, the predicted and experimental values of the two parameters in an external
validation set showed similar changes throughout the fermentation.
