The objective of this study was to develop a non-destructive, rapid and accurate analytical method to measure the quality(freshness) of egg. Near-infrared(NIR) spectra of 48 egg samples ranging from 70 HU(Haugh Unit) from 100 HU, PLSR(Partial Least Squares Regression) was used to build calibration model using the multiplicative scatter correction spectra in the 1100~1750 nm range. The results were very promising with correlation coefficient of 0.99 and standard error of prediction(SEP) of 1.35 HU. The overall results suggest that NIR spectroscopy can be used for rapid non-invasive determination of egg quality.
