The invention relates to a method for processing fresh meat and fish. The fresh meat is stored during a set time in an airtight chamber (1) to be locked after oxygen has been supplied thereto, in an atmosphere comprised mainly of oxygen, under a pressure higher than the atmospheric pressure. During the oxygen supply process (12), the temperature is selected at such a level and the supply set/controlled at so low a speed that the fresh meat cannot freeze. During storage, the pressure is so high and the storage duration so long that the fresh meat is entirely impregnated with oxygen. Furthermore, the oxygen exhaust is set/controlled at sufficiently low a speed to prevent fresh meat from freezing and enable the oxygen with which the processed fresh meat is impregnated to be removed with no blistering.

La présente invention concerne un procédé de traitement de viande/chair fraîche et de poisson, consistant à stocker la viande fraîche pendant un certain temps dans une chambre hermétique (1) verrouillable après apport d'oxygène, dans une atmosphère constituée essentiellement d'oxygène et à une pression supérieure à la pression atmosphérique. Lors de l'alimentation en oxygène(12), le niveau de température est choisi de telle manière et l'acheminement est réglée/régulée à une vitesse si faible que la viande/chair fraîche ne peut pas geler. Pendant le stockage, la pression est si élevée et la durée de stockage si longue que la viande/chair fraîche est entièrement imprégnée d'oxygène. Par ailleurs, l'évacuation de l'oxygène est réglée/régulée à une vitesse suffisamment faible pour éviter tout risque de congélation de la viande fraîche et permettre par ailleurs l'élimination, sans formation de cloques, de l'oxygène dont s'est imprégnée la viande fraîche traitée.
