Measurement of the hardness of wheat endosperm by near infrared spectroscopy.

Wheat hardness may be defined in terms of the way in which the endosperm behaves on a roller mill in which hard wheats produce a coarser flour with higher levels of starch damage than soft wheats. NIR spectroscopy may be used to measure hardness either by reflectance from ground wheat or transmittance through the whole grains. The basis of the measurement is that changes in the particle size of the meal or the internal structure of the grains due to hardness affect the NIR signal in a consistent manner. It is concluded that a hardness score may be derived by linear discriminant analysis of the NIR data without reference to any other method.
