    Dr. Ya-Jane Wang

    Dr. Wang received her B.S. in Agricultural Chemistry from National Taiwan University in 1986, M.S. in Food Science from University of Minnesota, Twin Cities in 1989, and Ph.D. in Food Science and Technology from Iowa State University in 1992. She joined the Food Science Department at the University of Arkansas as a Carbohydrate Chemist in 1999 after working at American Maize Products Company as a starch chemist for more than 5 years. She has worked extensively with rice breeders, agronomists, engineers, and food scientists in the U.S. and from different countries to investigate starch structures and properties in relation to rice quality and applications. She has also characterized the common and unique quality traits among U.S. and imported rice cultivars to identify the underlying starch characteristics that impact such traits. She has worked with companies using starch and rice in their products, such as rice producers and processors, cereals, granolas, beers, crackers, vegetarian/vegan products, sushi and mochi products.
