The objective was to study the foamability of two proteins after ultrasound application. Soy protein and whey protein isolate were used as starting material at pH used in the food processing. Ultrasound was used to analyze the foamability effect on the solutions relating with the bubble size change. The samples were sonicated at same conditions using an ultrasonic processor. Foam formation was measured by conductimetric and optical methods. Moreover, the evolution of the bubble size change was registered. Whey protein isolate solution was found a good choice to use as foaming agent at beverages preparations improved by ultrasound application.
