Modification of foaming properties of soy protein isolate by high ultrasound intensity: Particle size effect
The effect of high intensity ultrasound (HIUS) may produce structural modifications on proteins through a friendly environmental process. Thus, it can be possible to obtain aggregates with a determined particle size, and altering a defined functional property at the same time. The objective of this...

The effect of high intensity ultrasound (HIUS) may produce structural modifications on proteins through a friendly environmental process.

The objective of this work was to explore the impact of HIUS on the functionality of a denatured soy protein isolate (SPI) on foaming and interfacial properties. SPI solutions at pH 6.9 were treated with HIUS for 20 min, in an ultrasonic processor at room temperature, at 75, 80 and 85 °C.
