Notes:
Near infrared reflectance (NIR) spectroscopy was used to measure moisture, protein, and fat in spray-dried whole egg. Calibrations were developed for a commercial, filter monochromator NIR instrument and tested against standard methods. A standard error of performance (SEP) of 0.15% was obtained for moisture using a calibration based on three wavelengths. Protein and fat determinations by NIR were susceptible to variability due to sample particle size differences. Calibrations employing three wavelengths were used to measure protein and fat in samples of uniform particle size (SEP = 0.20% and 0.28%, respectively), but it was necessary to utilize additional wavelengths to adequately measure these constituents in samples having particle size variability (SEP = 0.38% for both protein and fat).
