Rheological Properties of Limited Enzymatic Hydrolyzed Wheat Gluten
The rheological properties of Limited Enzyme-hydrolyzed Wheat Gluten (LHWG) and its complex solutions with xanthan gum (XG), sodium alginate (SA) or gelatin were researched by Brookfield DV-Ⅱ+Pro Viscometer. The results showed that they all exhibited typical shear-thinning behavior and the higher LHWG concentration, the more evident of the shear thinning was. The effects of temperature on the rheology of LHWG were very complicated based on the concentration. The apparent viscosity of 300 mg/mL LHWG (20°C) was higher than that of 100 mg/mL and 200 mg/mL, and showed fluctuation between 20°C and 90°C, which were strongly different from that of low LHWG solution. However, the rheological properties of LHWG were influenced slightly by shearing time.
