A high pressure food package and system including a cup for holding a
quantity of food product, a lid for covering the cup, and at least one
one-way sealing mechanism that permits a gas to pass through the sealing
mechanism into the interior space enclosed by the cup and lid and that
prevents the gas from escaping from the interior space through the
sealing mechanism. The high pressure package (and system and method for
using the same) is especially well suited for producing a food product
(such as fruits or vegetables) having an effervescent sensory (or
carbonated) character.
