Protein adsorbed to the oil interface is reported in Table 1.
As expected, the protein per surface area of oil in the RBW
oleogel emulsions decreased as the concentration of emulsifier
increased, from 4.9 mg/m2 with no emulsifier to 3.0 mg/m2 at 0.2% emulsifier. This value was lower than either the milk fat
or HOSO controls. This could lead to a higher instability of the
emulsion during the whipping/freezing stage, which would promote
enhanced aggregation of this new system. Feijter and others
(1987) stated that the degree of protein displacement is related to
surfactant concentration and type. However, according to them,
the type of fat does not have a large effect on protein displacement.
