Abstract
The present invention relates to a container (3) comprising a first chamber (4) containing a foamable liquid; a self-heating element (5) which is in thermal contact with the foamable liquid; a pressurized gas which is contained in the first chamber or in a second chamber allowing release of the pressurized gas to the first chamber; and an outlet valve (1) which is in liquid communication with the first chamber. The container and/or the outlet valve can be used for dispensing foam and aerated liquid, preferably milk foam. Preferably the foamable liquid is milk, preferably dairy milk or plant based milk, more preferably pasteurized and/or sterilized dairy milk.
Claims14
A container for dispensing a heated product comprising 40-60 vol. % milk foam and 40-60 vol. % aerated milk, the container comprising
- a first chamber containing milk having a fat content of between 3 and 6 wt. %;
- a self-heating element which is in thermal contact with the milk and which upon activation heats the milk to a temperature of between 58 and 70 degrees Celsius;
- above 1 bar pressurized gas which is contained in the first chamber or in a second chamber allowing release of the pressurized gas to the first chamber;
- and
- an outlet valve which is in liquid communication with the first chamber,
- wherein the volume ratio between pressurized gas and milk in the container is between 0.3:1 and 1:0.3.
A method for preparing a heated product comprising 40-60 vol. % milk foam and 40-60 vol. % aerated milk, wherein the method comprises
- (a) providing a container comprising
- a first chamber containing milk having a fat content of between 3 and 6 wt. %;
- above 1 bar pressurized gas which is contained in the first chamber or in a second chamber allowing release of the pressurized gas to the first chamber;
- and
- an outlet valve which is in liquid communication with the first chamber,
- wherein the volume ratio between pressurized gas and milk in the container is between 0.3:1 and 1:0.3;
- (b) heating the milk contained in the first chamber to a temperature of between 58 and 70 degrees Celsius, preferably by combining the container with an external heater which can be placed in thermal contact with the milk;
- (c) shaking and/or agitating said container, preferably during the heating of step (b) until the milk reaches a temperature of between 25-40, preferably between 30-35 degrees Celsius;
- (d) activating and/or opening the outlet valve so as to produce the heated product comprising 40-60 vol. % milk foam and 40-60 vol. % aerated milk which is optionally subsequently added to espresso, coffee, or hot chocolate.
