The ethanol industry is booming. And extensive research is currently being pursued to develop alternative uses for distillers dried grains (DDG) and distillers dried grains with solubles (DDGS), coproducts of the ethanol production process. Currently, DDG and DDGS are used exclusively as livestock feed. previous research has shown promising avenues for the use of DDG and DDGS in human foods. The low starch, high protein and high fiber grains seem ideally suited for medical conditions such as diabetes and Celiac's disease. Processing methods need to be investigated to create functional flours that can be used effectively. Refining aspects such as color, odor, and baking functionality will eventually hold the key to the use of distillers grains in food products. The objective of this paper was to examine previous research on bleaching various food products, and to discuss their potential applicability for distillers grains. No research has yet been completed on bleaching distillers grains. This will be the topic of future research, and will be reported at a later date.
