Abstract
Abstract Concentrated emulsions of flavor oleoresins are prepared by (1) forming a solution or colloidal solution of the oleoresin in a diluent; (2) forming a preformed mixture comprising an emulsion stabilizer and at least one oil selected from the group consisting of edible and essential oils; (3) mixing said solution or colloidal solution with said preformed mixture with agitation; (4) adding an aqueous solution or dispersion of an emulsion stabilizer to form a final mixture; and (5) emulsifying said final mixture. The product aqueous emulsion may be spray dried to form an encapsulated oleoresin.

Claim 1
Independent Claim
94 words
A PROCESS FOR PREPARING AN AQUEOUS EMULSION OF A FLAVOUR OLEORESIN WHICH PROCESS COMPRISES FORMING, AN OLEORESIN SOLUTION OR COLLODIAL SOLUTION (A) OF THE OLEORESIN IN A DILUENT, MIXING SAID SOLUTION OR COLLODIAL SOLUTION (A) WITH AGITATION WITH A PREFORMED MIXTURE (B) COMPRISING AN EMULSION STABILISER, AND AT LEAST ONE OIL SELECTED FROM THE GROUP CONSISTING OF EDIBLE OILS AND ESSENTIAL OILS, ADDING AN AQUEOUS SOLUTION OR DISPERSION (C) OF AN EMULSION STABILISER TO FORM A FINAL MIXTURE (D), AND EMULSIFYING SAID FINAL MIXTURE (D) TO FORM AN AQUEOUS EMULSION OF SAID FLAVO OLEORESIN.
Claim 2
Dependent Claim
