A MILLING INDEX CALIBRATION DEVELOPED BY SAGGL USING A ROFF MILL
As we now know, maize hardness is a defining factor in the quality of the maize meal produced. For this reason, the South African Grain Laboratory (SAGL) has created a Milling Index calibration using a laboratory scale ROFF mill.
The Milling Index according to SAGL is an indication of the milling abilities and milling quality of maize kernels where a higher milling index means a higher extraction of the high-grade and most profitable products like super maize meal, samp, maize rice and maize grits (degermed products) manufactured from the corneous part of the endosperm. The Milling Index is an indication of the relative differences between samples tested.
