Foaming pressurized beverage
A method of making a pressurized packaged liquid beverage including filling a container including a one-way valve with a liquid mixture including a base liquid and a gum; sealing the container; introducing a volume of gas through the one-way valve after sealing the container; and agitating the container. When the container is opened, the liquid mixture increases in volume and separates into a liquid phase and a drinkable foam phase, which may persist for an extended period of time. The base liquid includes milk, coffee, fruit juice, or mixtures thereof.
1. A container adapted to hold a pressurized liquid beverage product, the container comprising:
a sidewall connected to a base at one end and a top at the opposite end, the base sidewall and top, the container having a single internal chamber, the single internal chamber adapted to
hold the pressurized liquid beverage comprising a base liquid and a gum, and
be agitated;
a one-way valve adapted to allow a gas to enter the internal chamber but not exit; and
wherein the pressurized liquid mixture is adapted to be saturated with a volume of gas and the container is adapted to be pressurized at a pressure ranging from approximately 20 pounds per square inch, to approximately 60 pounds per square inch.
2. The container of claim 1 , wherein the base liquid includes milk, coffee, fruit juice, or mixtures thereof.
3. The container of claim 2 , wherein the base liquid includes a mixture of milk and coffee.
4. The container of claim 3 , wherein the base liquid further includes chocolate.
5. The container of claim 1 , wherein the gum includes acacia gum, guar gum, locust bean gum, carrageenan, pectin, xanthan gum, or mixtures thereof.
6. The container of claim 1 , wherein the volume of gas includes nitrous oxide.
7. The container of claim 1 , wherein the container is a can, bottle, or keg.
