Definitions

  • This Invention concerns a method for the packaging of meat, sc that its preservation life is lengthened with the aid of carbon dioxide.
  • valve-packaging is also known which has been used for gaseous or gas-forming fluid packaging.
  • the packaging is described in GE publication 956123.
  • the purpose of this invention is to make the influence of the protective gas more effective for inmprovement of meat preservation. It is characteristic to the method according to the invention that the excess pressure of the carbon dioxide cas present in packaging at the beginning discharces through the valve in it. Due to the excess pressure the dissolution cf the carbon dioxide into the meat is improved.
  • the increased preservation is founded on the influence of the excess pressure gasefication of the carbon dioxide on the passificat- ion of the bacterial flora. It is of fundamental significance in the method in question that excess pressure is formed in the packaging for 0.5 - 1 h, which conclusively improves the effects of the carbon dioxide.
  • the excess pressure can be regulated by changing the construction of the valve.
  • the gas- and aroma tight packaging material is composed of a simple gas-tight plastic film or its various laminations.
  • the package is furnished with a special gas valve.
  • the package is formed and closed by seaming, for example by heat seaming or by gluing.
  • the valve is formed together with the seaming in such a way that at a suitable position a labyrinthine passage is formed in the package.
  • the packaging is marked with reference number 1 and the passage formed by the valve is at the area 2.
  • the opening connecting to the packaging space to be used is at 3 and the opening to the outside air is at 4.
  • the meat to be packed is placed in the package together with the carbon dioxide ice and the package is closed and the air extracted from it as carefully as possible.
  • As the pressure rises inside the gas can slowly discharge intc the surrounding space along the labyrinth.
  • the time of the carbon dioxide discharge can be regulated by suitably selecting the length of the valve labyrinths 2 and the size of the openings 3 and 4
  • the packaging material can be, for example, laminates, in which the polyamide- or polyester film and polyethylene film, are laminated together, or polyamide and polypropylene film.
  • the package is furnished to advantage with at least two valves ( Figures 2- 4 ).
  • a 2 kg. pork chop line was packed with the aforementioned method so that 15 g carbon dioxide ice was added in the valve package.
  • the size of the package used was 300x400 mm.
  • Tha package had a double valve according to the invention, the width of which was 30 mm.
  • the packaging material was nylon&polyethylene laminate, the layer thicknesses of which were 20 and 70 microns.
  • the aforementioned sensory evaluation was a mean figure given by a panel composed of 4-6 experts on the following scale of values
