ABSTRACT:
A process for deoxygenating or carbonating a food or biological liquid product having an initial dissolved oxygen concentration between 9 mg/l and 12 mg/l, comprising injecting at least one gas selected from the group consisting of nitrogen and carbon dioxide into a current of the food or biological liquid product thereby to form a gas/liquid emulsion. The emulsion is introduced into a storage vessel. The gas is at a pressure of about 3 bars. The gas and liquid are injected into a confined mixing chamber at a volume rate of gas to liquid between 3 and 5, and expelled the chamber at a velocity of 15 to 30 meters per second into the vessel above the bottom of the vessel a distance which is a minor proportion of the height of the vessel, until the residual dissolved oxygen content is less than 0.25 mg/l.
