Abstract

Micro mill with small sample size (5-10 g) can substitute the lab grinders operating with some hundred grams of samples. The flour and semolina yields produced by micro mill procedure are significantly lower compared to macro method but their quality are good. A significant shift in mass distribution as well as in distribution of ash content of fractions was observed during micro mill procedure. The micro-scale separation resulted a higher ratio of endosperm in the bran fraction and low ash content flour. Near infrared (NIR) technique was able to indicate the differences between the fractions taken by macro or micro method. The applied NIR calibration and polar qualification system (PQS) methods were sensitive spectrum processing procedures in detection and evaluation of milling action both qualitatively and quantitatively.
