Technical Abstract: Improvement in the quality and thus added value for agricultural materials involves the understanding of their underlying chemical composition in relation to anatomical features or morphology. To this end the, so-called, chemical imaging techniques that provide both spatial and spectral information have become essential tools of the trade. No one technique provides all the necessary information. Three spectroscopic imaging techniques that have become popular in recent years are: Nuclear Magnetic Resonance or Magnetic Resonance Imaging (MRI), infrared and Raman imaging. Each of these techniques has its own advantages and disadvantages, but used together provide a powerful synergism. Examples of their use in research on fruits, grains and fibers will be presented.
