ABSTRACT:
A beverage-bottling method for non-carbonated beverages. An inert gas, other than carbon dioxide, such as nitrogen, is injected into a non-carbonated beverage prior to filling a container. Inert gas is permitted to escape from the beverage in the filled container before sealing the container. The amount of gas released is sufficient to strip dissolved oxygen from the beverage and then purge air from the headspace of the container. Sufficient gas is retained in the beverage to exert a superatmospheric pressure after the container is sealed. The reduction in oxygen content of the headspace is superior to that achieved with using a stream of nitrogen purging gas into the headspace, while dissolved oxygen is substantially reduced and internal container pressure is increased, the latter being a distinct advantage in containers made of flexible material such as sheet metal and plastic.
