The emulsion was prepared by using a model system,
as described by Ockerman (1985) and Zorba et
al. (1993b). The yolk solution (100 mL) and 100 mL
of oil were placed in the blender (Kenwood KM300,
Kenwood Ltd.). During emulsification at 6,500 rpm,
200 mL of oil was added at a rate of 1.0 to 1.1 mL/s.
After all the oil was added, the emulsion was mixed for
an additional 5 s.
