The influence of incompatibility on the formation of adsorbing layers and dispersion of n-decane emulsion droplets in aqueous solution containing a mixture of 11S globulin from Vicia faba and dextran

Adsorption and rheological properties of biopolymers at the air‐water interface

“…An increase in k diff occurs as a consequence of increasing protein bulk concentration 9, 19, 34, 41. Excluded volume effects in protein‐PS mixtures can have an effect similar to increasing protein concentration because of the increased thermodynamic activity of the protein in the bulk solution,32 and can lead to an increase in protein adsorption at fluid interfaces 46. In the presence of xanthan gum, although the incompatibility with the protein increases its effective concentration in the bulk, the effect of the increased viscosity prevails at 0.5 wt % of xanthan in the bulk.…”
