Rheology of Protein Foams

Lexis, Meike

Abstract:
Foams with gas volume fractions f>fc possess peculiar rheological properties, a minimum stress called yield stress is needed to initiate foam flow and below foams behave as viscoelastic solids with a storage modulus G'>G''. Beyond the widely accepted physical models predicting elastic modulus and yield stress from the Laplace pressure within the gas bubbles and the gas volume fraction these quantities strongly depend on corresponding interfacial properties.
