Cereal processing
Common wheat (Triticum aestivum).
In the process of milling wheat, approximately 72 percent of the grain is recovered as white flour.12
The objective of this milling process is to separate the floury endosperm from the outer branny coverings and the germ. Because white flour excludes the germ, it has a longer shelf life compared to whole-kernel products like graham flour, which can become rancid due to the retention of germ oil.32
