Reflectance spectra of minced sausages were obtained on a
Foss-NIRSystems 6500 SY-II monochromator (Foss NIRSystems,
Silver Spring, MD), from 400 to 2498 nm, every 2 nm (spectral
bandpass 10 nm ± 1 nm) Analysis was performed using a transport
module. Samples were scanned using a 1=4 rectangular cup that was
4.6 cm wide and 5.7 cm long. Reflectance data were stored as the
logarithm of the reciprocal of reflectance (1/R), collecting 1050
data points per sample.
