Abstract
Abstract The present invention relates to a process for the production of a water-in-oil-in-water (W/O/W) type multiple emulsion for foods, which is very fine and exhibits excellent stability. A stable W/O/W type multiple emulsion is obtained by using a polyglycerol polyricinoleate to obtain a fine W/O emulsion in a primary emulsification, and adding a water phase containing an emulsifier to the resulting W/O emulsion and mixing by agitating in a secondary emulsification.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
51 words
A process for the production of a water-in-oil-in-water (W/O/W) emulsion for foods, which comprises adding a water phase containing an emulsifier to a W/O emulsion obtained from a water phase and oil or fat containing a polyglycerol polyricinoleate, and mixing said phases under homogenization conditions effective to produce said multiple emulsion.
Claim 2
Dependent Claim
51 words
A process for the production of a water-in-oil-in-water (W/O/W) emulsion for foods, which comprises adding a water phase containing an emulsifier to a W/O emulsion obtained from a water phase and oil or fat containing a polyglycerol polyricinoleate, and mixing said phases under homogenization conditions effective to produce said multiple emulsion.
Claim 3
Dependent Claim
50 words
A process for the production of a W/O/W emulsion for foods as set forth in claim 1, wherein the W/O emulsion is obtained by mixing oil or fat containing a polyglycerol polyricinoleate with a water phase to form an O/W emulsion and agitating said O/W emulsion to reverse the phases.
Claim 4
Dependent Claim
26 words
A process for the production of a W/O/W emulsion for foods as set forth in claim 1, wherein the emulsifier is a sucrose fatty acid ester.
