Abstract

Two-dimensional (2D) correlation analysis has been applied to analyze protein and fat concentration-dependent near-infrared (NIR) spectral variations of milk. Synchronous and asynchronous 2D correlation spectra of milk enhance spectral resolution and provide information about concentration- dependent intensity changes not readily accessible from one-dimensional spectra. The asynchronous 2D correlation map shows marked differences between the protein and fat concentration-dependent spectral changes.
