Abstract
Abstract An emulsion preconcentrate which contains hydrolyzed coffee oil and a coffee aroma. The emulsion preconcentrate is mixed with soluble coffee powder to provide a soluble coffee product. Upon dissolution of the soluble coffee product in hot water, the emulsion preconcentrate spontaneously forms an oil-in-water emulsion including droplets in the microemulsion tange; the dispersed oil phase containing the aroma. This provides a burst of aroma.
