Abstract
The present invention provides a foaming instant coffee composition comprising particles having a bulk density of from 0.16 to 0.45 g/cm3, said particles comprising a continuous phase comprising an instant coffee matrix and a non-continuous phase comprising particles of a foamable component containing a gas.
Claims13
A process for preparing a foaming instant coffee composition comprising the steps of:
- i. mixing particles of a foamable component with an aqueous coffee extract to form a coffee mixture;
- ii. before the particles of the foamable component have dissolved, freezing the coffee mixture;
- iii. granulating the frozen coffee mixture;
- and
- iv. forming the foaming instant coffee composition by removing water by sublimation, wherein the foaming instant coffee composition includes a continuous phase comprising an instant coffee matrix and a non-continuous phase comprising particles of the foamable component containing a gas, the non-continuous phase being entrapped within the instant coffee matrix.

A process for forming a foaming freeze-dried instant coffee composition comprising the steps of:
- cooling an aqueous coffee extract to a temperature of less than about 5° C.;
- cooling particles of a foamable component to a temperature of less than about 5° C.;
- mixing the particles of the foamable component with the aqueous coffee extract to form a coffee mixture;
- before the particles of the foamable component have dissolved, freezing the coffee mixture;
- removing water by sublimation from the coffee mixture to form the foaming freeze-dried instant coffee composition, wherein the foaming freeze-dried instant coffee composition includes a continuous phase comprising an instant coffee matrix and a non-continuous phase comprising particles of the foamable component containing a gas, the non-continuous phase being entrapped within the instant coffee matrix.
