In addition to the polished whole white rice, various co-products, including rice bran and broken rice, are generated during the milling of rice. In spite of plentiful supply and high nutrition, rice bran, and to a lesser extent, broken rice kernels are under-priced and under-utilized. The present review focuses on selected examples in developing methods to promote the use of and add value to these co-products. Rice products with up to 92% protein were prepared. Edible films were developed using the protein-enriched products and the polysaccharide pullulan. Rice flour or its starch component was modified for improved functional properties, and then used to prepared batters, which compared favorably to traditional wheat batters in general qualities, but absorbed as much as 70% less oil during frying.
