NIR Hyperspectral Imaging Methods for Quality and Safety Control of Food and Feed Products: Contributions to Four European Projects

IR hyperspectral imaging instruments have significant advantages and are becoming the technique of choice for the analyst seeking to solve specific analytical problems. The addition of the spatial di mension to the frequency and absorbance dimensions opens the door to easy collec tion of thousands of spectra from one sam ple; instead of having one spectrum per sample with which to determine a series of parameters, one has thousands of spectra of sub-fractions of the samples on which one can individually determine parameters of interest in order to make some conclu sions about the individual sub-fractions or on the status of the entire sample. 1
