The innovations of near infrared (NIR) technology are effectively used in the quality control field of cereal science and technology. The aim of this study was to elaborate NIR methods for testing and recognition of chemical components and quality in 'Pannon wheat' milling fractions as well as to develop spectroscopic methods following the milling processes and evaluate the milling actions, the stability of the milling technology by different types of milling products. Milling fractions of the 'Pannon Standard' and the 'Pannon Premium' wheat categories were produced from allied (i.e. true to variety or variety identical) wheat under industrial conditions where samples were collected versus sampling times and maximum or minimum yields. The changes of the main chemical components (starch, protein, lipid) and physical properties of fractions were analysed by dispersive spectrophotometers using visible and/or NIR regions of the electromagnetic radiation. Close correlations were obtained between the data of spectroscopic measurement techniques processed by various chemometric methods (principal component analysis, cluster analysis) and operation condition of wheat milling technology. During this task, it became obvious that the NIR methods are able to detect the differences of the maximum and minimum yield settings within one fraction and differences arising from the sampling times by some variety of fractions, respectively.
