Rheological method for kinetics of drainage and disproportionation of soy proteins foams

The effect of soy protein (SP) concentration and denaturation on foaming properties was investigated. To measure drainage and disproportionation rates, a special method was based on measurements of time dependency of foam viscosity. Foam expansion reached a maximum at 3% protein concentration for de...

To measure drainage and disproportionation rates, a special method was based on measurements of time dependency of foam viscosity. Foam expansion reached a maximum at 3% protein concentration for denatured and 5% for native SP.
