The present invention is directed to a method for producing a microcapsule flavor delivery system. In the method, a mixture of a flavoring material selected from the group consisting of an oil soluble flavor dissolved in an oil and an o/w emulsion flavor and a protein solution is provided. The mixture is subjected to low shear mixing to provide an o/w water pre-emulsion. The pre-emulsion is subjected to high shear mixing or sonication to provide an o/w emulsion having a coating of protein around the internal oil droplets. The o/w emulsion is mixed with a liquified hard fat which is solid at room temperature. The mixture of hard fat and o/w emulsion is atomized onto a planar surface or into a fluid to provide microcapsules which are an o/w/o multiple emulsion having a flavoring material in the internal oil phase or o/w emulsion.
