Abstract
Abstract The present invention relates to a process for preparation of dressings comprising W/O/W type multiple emulsions. Dressings comprising a quite stable W/O/W type multiple emulsions can be obtained by using monoerucin, dierucin, or polyglycerol polycondensed ricinoleic acid ester as the emulsifier. A quite fine W/O/W type emulsion can also be obtained, since an O/W emulsion is subjected to a phase inversion to form a W/O emulsion in the first place.
