Soft White Winter Wheat Kernel Separation by Percent Protein

Abstract

Eighty-five percent or more of the soft white wheat grown in the Pacific Northwest (PNW) is exported. About half of this wheat is sold to Pacific Rim countries that require wheat with high test weight and less than 10.5% grain protein for making products such as pocket breads, cookies, and sponge cakes. Soft white wheat grown in the PNW varies from less than 7 to over 14% grain protein content and has test weights ranging from less than 700 to over 800 kg/m3.
