One aspect of the invention relates to an aerated water-continuous
oil-and-water emulsion having an overrun in the range of 10-500%, said
emulsion comprising: 5-90 wt. % of an oil phase; 10-95 wt. % of an
aqueous phase; 0.3-30% by weight of the aqueous phase of one or more egg
yolk granule proteins selected from high density lipoprotein (HDL) and
phosvitin; and from 0.05 up to 10% by weight of the aqueous phase of one
or more egg yolk plasma proteins selected from low density lipoprotein
(LDL) and livetin;wherein the weight ratio of egg yolk granule proteins
to egg yolk plasma proteins exceeds 1:1.
The aerated emulsions according to the present invention can easily be
produced at a high overrun. Furthermore, the foam structure of these
emulsions remains surprisingly stable during shelf life.
