Abstract: A process for extracting spices in liquid carbon dioxide in the presence of an alimentarily acceptable cosolvent which does not degrade the flavors of the spices. The process is particularly applicable to the extraction of piperine and aromatic compounds of pepper.

Abstract: The process, applied to inerting of airtight packagings, used together or separately the deoxygenation of empty packagings under inert atmosphere, purging of the gas ceiling of the packagings after filling and before closing with an inert fluid, under inert atmospheres, each operation being performed by two simultaneous injections of fluid; said liquid or pasty product optionally being deoxygenated by an inert gas. This technique is applicable to the preservation of any liquid, pasty, solid and powdery food product, to pharmaceutical and biological products.

Abstract: Apparatus is provided for providing an inert atmosphere in airtight packages, which apparatus is adaptable for use in a packaging line. The apparatus comprises an inerting minitunnel which is provided with a ramp for purging oxygen from the packages, and an inerting ramp. The apparatus can be used with any liquid, pasty, or solid product which is packaged in an airtight package.

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.
