Kinetics of Liquid Drainage from Protein‐Stabilized Foams
Drainage of 14 protein‐stabilized foams was determined as a function of time. Drainage conformed to the empirical equation v = Vt/(B + t), where v is the volume of drained liquid at time t, V is the maximum drained volume, and B is the time needed to drain V/2. Rate constants and initial rates of dr...

| Sumario: | Drainage of 14 protein‐stabilized foams was determined as a function of time. Drainage conformed to the empirical equation v = Vt/(B + t), where v is the volume of drained liquid at time t, V is the maximum drained volume, and B is the time needed to drain V/2. Rate constants and initial rates of drainage could be calculated from parameters V and B. However, B would be the preferred index of foam stability as it was not influenced by the initial volume of liquid in the foam. Copyright © 1991, Wiley Blackwell. All rights reserved |
