All of the Kansas varieties of white wheat,milled to 80% extraction,performed as well as,if not better than,a standard commercial tortilla flour milled to 72% extraction when various quality factors were compared. Tortillas were made from eight wheat cultivars milled at 80% extraction: four HWW wheat cultivars included Betty,Heyne,Oro Blanco and NuWest; three hard red winter (HRW) wheat samples were Jagger and Ike grown at Hutchinson,Kansas (Ike-Hutch) and at Hays,Kansas (Ike-Hays); and one hard white spring (HWS) wheat cultivar,Idaho 377-S. Tortillas made from these flours were compared to tortillas made from one commercial tortilla-flour milled to 72% extraction from a blend of HRW wheat. Mixograph parameters,starch pasting properties,dough-handling characteristics and tortilla- making attributes of the new Kansas HWW wheat cultivars,Betty and Heyne,were superior. In summary,Kansas HWW wheat flours,milled to 80% extraction,produced tortillas which were equal to,or superior to,those made from 80%-extraction HRW wheat flours and 72%-extraction commercial tortilla flour.展开更多
