Influence of Whole Meal Granularity on Analysis of HRS Wheat for Protein and Moisture by Near Infrared Reflectance Spectroscopy (NRS).

Granulation of a wheat whole meal embodies mean particle size and particle size distribution. Granulation affects the accuracy and precision of testing of wheat and other grains for protein and moisture by means of near-infrared reflectance spectroscopy (NIRS). The grinding procedure and the moisture and protein levels of the wheat before grinding principally affect the granulation itself. Some of these factors are nonlinear in influence. This article describes the manner in which granularity, moisture, and protein levels influence the accuracy and precision of NIRS protein and moisture testing of hard red spring wheat. Calibration practices minimize errors caused by these factors.
