متن کاملQuantitative Characterization of Feed and Agricultural Samples Using a Handheld Near-Infrared Analyzer
Background Near-infrared (NIR) spectroscopy has been widely accepted for use in the food and agricultural areas, beginning with the work of Karl Norris at the USDA to develop quality methods for agricultural products. However, since NIR spectra are overtones and combinations of fundamental IR spectra, the peaks tend to lose definition and broaden, representing general features due to CH, NH and...

متن کاملExploring authentic skim and nonfat dry milk powder variance for the development of nontargeted adulterant detection methods using near-infrared spectroscopy and chemometrics.
A multinational collaborative team led by the U.S. Pharmacopeial Convention is currently investigating the potential of near-infrared (NIR) spectroscopy for nontargeted detection of adulterants in skim and nonfat dry milk powder. The development of a compendial method is challenged by the range of authentic or nonadulterated milk powders available worldwide. This paper investigates the sources ...
