Topic: Nutritional Properties of Agricultural Process Waste Streams
Dr. Wally Yakoyama
USDA ARS Western Regional Research Center
The processing of agricultural commodities such as grains, soybeans, corn, wine grapes, fruits, and vegetables produces considerable amounts of "waste" that is typically fed to farm animals or dumped. Often the waste materials have flavor or textural characteristics that are undesirable to consumers, but are potentially valuable nutritional products. Many polyphenolic antioxidants occur in the bran, skin, or seed of plant products. They are often removed because they are bitter or astringent. Polyphenolics are typically found in the presence of dietary fiber. Dietary fibers have a range of organoleptic and nutritional properties. The effects of polyphenolics and fiber in human and animal studies will be reviewed.
Dr. Yokoyama received a B.S. Chemistry, UCLA and PhD Biophysics, UCD. He is currently employed at the USDA, Western Regional Research Center, Albany, CA. His current research focuses on understanding and preventing obesity related metabolic diseases by polyphenolics in wine grape pomace and other processing byproducts. Animal models and molecular methods are used to determine the differences in the expression of genes that regulate fat and carbohydrate metabolism in normal and insulin resistant animals fed diets supplemented with fractions from processing byproducts.
Coffee and cookies will be served.
