  • COMPOSITE FILMS FOR PACKAGING FRESH RED MEAT AND FISH
    Publication number: 20120009305
    Abstract: Disclosed are a composite film, and use of the film, in which the film has an oxygen permeation rate of from about 50 to about 2000 cm3×mil/[m2×day] and comprises or is produced from at least one sealant layer and at least one barrier layer for packaging fresh meat or fish product. The sealant layer comprises an ethylene or ethylene copolymer that contacts the fresh meat or fish product which has been pretreated in an oxygen atmosphere having a pressure of about 6 to about 20 bar (6×105 to 2×106 Pascals).

  • Method and device for processing fresh meat
    Patent number: 6716464
    Abstract: 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 therein, 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.

  • Method of preserving tissues and organs
    Patent number: 5791151
    Abstract: A method is described for preserving tissues and organs, in particular of tissues and organs for transplantation, in which the tissue or organ to be treated is temporarily stored in a well-cooled state, in particular at a temperature in the range from -3.degree. C. to 3.degree. C., for a predeterminable time in an oxygen atmosphere, in a space which can be closed off in air tight manner, wherein the oxygen atmosphere is built up in the space which can be sealed off in air tight manner with a pressure which lies above the atmospheric pressure, and wherein the pressure in the closed space is kept at a pressure lying above the atmospheric pressure for the whole or the further period of intermediate storage.
