Determination of total volatile basic nitrogen (TVB-N) content and Warner-Bratzler shear force (WBSF) in pork using Fourier transform near infrared (FT-NIR) spectroscopy

► NIR spectroscopy technique was attempted to rapidly determine the pork quality. ► Improving the model performance by optimising spectra preprocessing and PLS factors. ► Spectra region selection by SI-PLS will improve the model quality.
