Molecular weight, solubility and viscosity of β-Glucan preparations from barley pearling byproducts

β-Glucan, the representative dietary fibre component of barley, has received much attention, primarily due to its nutritional significance. In this study, β-glucans prepared from barley pearling byproducts were characterized with respect to their molecular weight, solubility and viscosity. Following...
