Funded by a one-year $30,000 grant from the kansas wheat commission. sajid Alavi,an assistant professor of grain science and industry at k-state;s college of agriculture. and fellow researchers created flour enriched with varying levels of bran. they mixed the bran-enriched wheat flour with water using a standing mixed like the one cooks may use at hom and they let the dough sit overnight. the hydrated flour was then sent through a machine called an extrusion processor. the processor uses a series of rotating screws and heated barrels to precook the flour before it's pushed out of the end. after ropes of the dough come out they are taken to a drying oven or a freeze dryer the latter of which alavi said produced higher-quality flour then the dried ropes were ground back into flour ready to use for baking
