Can NIR detect contaminants in fish meal?

Hi all,
Fish meal adulterated with urea, melamine, cyanuric acid, amoniac and even feather meal is not good to be predicted by fish meal calibration model. When I scan these samples in NIR, GH is in the limit but protein result is lower than Kjeldahl or Dumas method so I don't know when I can trust or not my result. Do we have a tool which can detect true fish meal and fish meal adulterated?
Thank in advance,
