AACCI Method 39-70.02
Near-Infrared Reflectance Method for Hardness Determination in Wheat

VIEW METHOD

Objective
Near-infrared reflectance (NIR) spectroscopy provides a rapid measurement of certain compositional factors of a ground sample of grain. Reflectance signal is affected by particle size (near-infrared absorption increases with increase in particle size), and particle size of ground wheat increases with hardness. Therefore, NIR can be used to indicate hardness of wheat as well as other factors relating to composition. This method is applicable to all classes of wheat.
