Abstract: The present invention is directed to isolating the valuable components of cereal grains and allowing the benefits to be more fully exploited. The concept of the present invention initially involves selection of cultivars of cereal grains such as wheat, barley, oats and rye having desired bioactive components including antioxidants, complex phenolics, lignans, flavonoids, vitamins, fiber, protein and other nutrients concentrated in one or more of the outer bran layers. Then separating the outer bran layer into three fractions, according to the desired bioactive components contained in the bran layers including antioxidants, complex phenolics, lignans, flavonoids, vitamins, fiber, protein and other nutrients. This allows the maximum benefit and value to be obtained from the bran fractions as dietary supplements, nutraceuticals, or as enriched food products.
