Measuring Wheat Flour Purity Using Quantitative NIR Chemical Imaging
Isolating material of commercial value from solid natural products presents a challenge for many spectroscopic techniques. Near-infrared (NIR) chemical imaging makes it possible to obtain spectra from individual pixels within a field of view for analysis of complex, heterogeneous mixtures. A team at Kansas State University, led by David Wetzel, has been applying this approach to multiple applications, including the analysis of wheat. In particular, the group has work on alternative methods for the determination of flour and milling stream purity, because outdated methods such as mineral ash residue impurity analysis do not properly reflect the quality of the final products of milling and are dependent upon the soil where the wheat is milled. Mark Boatwright, who is studying for his doctorate under Wetzel, talked to Spectroscopy about some of this work.
