摘要: Abstract The cereal dietary fibre β-glucan has outstanding functional and nutritional properties, because of its viscosity in aqueous systems the intestinal tract. rheological behaviour (concentrations: 2% 4%) isolated from extruded autoclaved oat meal bran was evaluated using oscillatory measurements. In frequency sweep, storage loss moduli G′ G″ preparations increased continuously with increasing frequency, showing a dominantly viscous behaviour. With elastic properties improved. β-Glucan also showed exception meal, were not influenced by deformation amplitude sweep. Complex viscosities decreased (in all samples) independent bran). shear experiments, solutions structurally non-Newtonian rheostable (2%) had highest that lowest apparent process viscosities. Fluid dynamic parameters may influence flow, diffusion or transport during digestion processes small intestine, but is limited.
