Popis: Fortifying bread with β-glucan has been shown to reduce bread quality and the associated health benefits of barley β-glucan. Fortification of bread using β-glucan concentrates that are less soluble during bread preparation steps has not been investigated. The effects of β-glucan concentration and gluten addition on the physicochemical properties of bread and β-glucan solubility and viscosity were investigated using a less soluble β-glucan concentrate, as were the effects of baking temperature and prior β-glucan solubilization. Fortification of bread with β-glucan decreased loaf volume and height (P ≤ 0.05) and increased firmness (P ≤ 0.05). Gluten addition to bread at the highest β-glucan level increased height and volume (P ≤ 0.05) to values exceeding those for the control and decreased firmness (P ≤ 0.05). β-Glucan addition increased (P ≤ 0.05) extract viscosity, as did gluten addition to the bread with the highest β-glucan level. Baking at low temperature decreased (P ≤ 0.05) β-glucan viscosit...
