Rice bran was provided by the US Department of Agriculture-Agricultural Research Service (USDA-ARS) Dale Bumpers Rice Research Unit (Anna McClung) and was derived from a single source (Oryza sativa L. ssp. japonica var. Neptune). The rice bran was heat-stabilized by heating at 100 °C for three min to inactivate the lipase/lipoxygenase enzymes and prevent the bran from becoming rancid
