TY - JOUR N2 - n indirect, non-destructive, inexpensive and simple method for testing hardness of sorghum grain was developed using density grading in sodium nitrate solution with a density of 1·315 g/ml at 25°C. The percentage of floating kernels was highly correlated with percentage vitreousness, the grain hardness determined as work required for grinding, flour particle size, and with rheological properties of a sorghum flour dough.
