Analysis of chalk in rice by two-dimensional correlation spectroscopy

To extract the characteristic information of chalk in rice, the chalky milled rice were analyzed systematically by mid-infrared (IR), near-infrared (NIR) spectra analysis and two-dimensional (2D) correlation spectroscopy. 24 non-chalky and 24 chalky rice samples for four types milled rice were prepared in laboratory. NIR diffusing reflection and IR attenuated total reflection (ATR) spectra of all samples were collected at room temperature. The...
