Abstract
Abstract The present invention relates to a process for preparing dressings comprising W/O/W type multiple emulsions. A W/O/W type emulsion can be obtained by phase inversion from W/O type emulsion by adding an aqueous phase to an oil phase containing monoerucin, dierucin, or polyglycerol polycondensed ricinoleic acid ester as the emulsifier under agitating. Also, dressings having an excellent richness can be provided.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
124 words
A process for preparation of dressings comprising W/O/W type multiple emulsions which comprises adding an emulsifier selected from the group consisting of monoerucin, dierucin, and polyglycerol polycondensed recinoleic acid ester to an oil in an amount of 0.1 to 15% based on said oil, adding said oil, containing said emulsifier, to an inner aqueous phase in a ratio of 3/1 to 1/3 to obtain an O/W type emulsion, phase-inverting the emulsion by additional agitating to obtain a W/O type emulsion, adding vinegar to water in an amount effective to season a dressing to form an outer aqueous phase, adding the W/O type emulsion to an amount of said outer aqueous phase effective to obtain a dressing, and agitating the mixture to obtain said dressing.
Claim 2
Dependent Claim
124 words
A process for preparation of dressings comprising W/O/W type multiple emulsions which comprises adding an emulsifier selected from the group consisting of monoerucin, dierucin, and polyglycerol polycondensed recinoleic acid ester to an oil in an amount of 0.1 to 15% based on said oil, adding said oil, containing said emulsifier, to an inner aqueous phase in a ratio of 3/1 to 1/3 to obtain an O/W type emulsion, phase-inverting the emulsion by additional agitating to obtain a W/O type emulsion, adding vinegar to water in an amount effective to season a dressing to form an outer aqueous phase, adding the W/O type emulsion to an amount of said outer aqueous phase effective to obtain a dressing, and agitating the mixture to obtain said dressing.
Claim 3
