The effects of the addition of two barley b-glucan isolates (0.2–1.0% of wheat flour), differing in molecular weight, and water (53–63% in a poor breadmaking wheat flour, cv. Dion, and 58–68% in a good breadmaking wheat flour, cv. Yekora) on the viscoelastic properties of wheat flour doughs were investigated. A response surface model (CCF) was used to evaluate the effects observed on the dynamic and creeprecovery parameters of the dough. The evaluation was done separately for each combination of b-glucan isolate (BG1 of 105 Da and BG2 of 2 105 Da) and flour type. Besides the contents of b-glucan and water, the molecular size of the polysaccharide and the flour quality were important determinants of the dough’s viscoelastic behavior. Compared to BG1, the higher molecular weight b-glucan (BG2) brought about major changes on all the rheological responses of the fortified doughs. The addition of appropriate levels of b-glucans and water in the poor breadmaking cultivar (Dion) doughs could yield similar viscoelastic responses to those observed by a non-fortified good breadmaking quality flour dough (Yekora).
