Mixed soy globulins and β-lactoglobulin systems behaviour inaqueous solutions and at the air-water interface

It has been studied in this work the effect of mixing soy globulins (β-conglycinin and glycinin) with β-lactoglobulin (βlg) both in the bulk phase and also in their interfacial (air-water interface) and foaming properties, at pH 3.0 and 7.0 and 20°C. The analyzed properties of these systems were: pa...
