W1/O/W2-TYPE DOUBLE EMULSION DRESSING AND METHOD FOR PRODUCTION THEREOF

摘要

The invention provides a W1/O/W2 type composite emulsified dressing characterized in that it comprises a polyglycerol polyricinoleate having a degree of esterification of 10-30% and a degree of ricinoleic acid-condensation of 5-8 and that it has a viscosity of 1,000-300,000 mPa·s, and a method for the preparation of the dressing which comprises the steps of 90-10 parts by mass of an aqueous phase (W1) is mixed with 10-90 parts by mass of an oily phase (O) to thus form a W1/O type emulsion and then 100 parts by mass of the resulting W1/O type emulsion is blended with 25-150 parts by mass of an aqueous phase (W2) to thus give a W1/O/W2 type composite emulsified dressing, wherein the dressing comprises a polyglycerol polyricinoleate having a degree of esterification of 10-30% and a degree of ricinoleic acid-condensation of 5-8, in an amount ranging from 0.01-5% by mass on the basis of the total mass of the W1/O/W2 type composite emulsified dressing. The dressing are quite excellent in their storage stability.
