While it is known parboiling grains before milling helps retain essential micronutrients, researchers from Charles Sturt University (CSU) and the NSW Department of Primary Industries (DPI) have used the Australian Synchrotron to compare parboiling techniques, showing in the LWT — Food Science and Technology journal that longer parboiling processes at higher temperatures cause more micronutrients to migrate from the outer
bran layer into the starchy core of the grain.
