Soft wheat quality: sponge cakes
The OSU Cereal Quality laboratory investigates the molecular phenomena that control the characteristics of wheat-based foods and uses this knowledge to maximize the probability of selecting new wheat varieties with improved end-use performance in conventional uses (bread,cookies, etc) and to where possible identify and exploit novel quality traits of potential value. A key activity is providing basic quality data and support for the wheat breeding program, and for our companion research programs in extension and genetics. We also investigate laboratory techniques that could make the breeding process more efficient and more effective (i.e. faster and/or cheaper and more capable of identifying required quality traits). Dr Ross was recently professionally trained in artisan-style baking techniques at the San Francisco Baking Institute. This was part of a strategy shift emphasis towards investigations of higher value, hand-crafted breads that could provide a regional outlet for Oregon hard wheats.
