The single-kernel characterization system (SKCS) crushes
individual kernels and uses algorithms based on the force-deformation profile
data to classify wheat samples into soft, hard, or mixed market classes.
Those data were utilized to produce a predictive equation for softness
equivalent (SE), a direct measure of wheat kernel texture obtained from
milling wheat on a modified Brabender Quadrumat Jr. mill and sieving system.
Predicted SE values had a high correlation (r(^2) = 0.996) with actual
SE milling values. In contrast to SKCS hardness index values, predicted
SE values accurately responded to varying kernel moisture content and kernel
size, within the ranges examined. Therefore, using the SKCS data to predict
an independent measure of kernel texture (e.g., SE) may be a valuable augmentation
to or replacement for using SKCS algorithms to classify wheat.
