  "Emballage à vide   d'air   pour la viande   fraîche   et congeléc". 



   Il est connu que la viande fraîche, comme aussi la viande décongelée, est empaquetée pièce par pièce dans un sac en plastique transparent et que le tout est mis à vide d'air pour être ensuite forme horméjtiquement. Ces emballages sont ensuite emmagasinés dans un frigoruifique pour être vendus plus tard, ce qui peut durer un certain temps, 
En tranchant la viande, les   cnllules   musculaires, conne aussi les   membranes   cellulaires, sont   blessées   de telle façon que le suc cellulaire sort des cellules et s'accurmule au fond de l'emballage. 



   Plus la viande est tranchée en petits morccaux, plas   :le   suc cellulaire s'accumule dans l'emballage. Ce suc cellulaire 

 <Desc/Clms Page number 2> 

 présente un   nilieu   excellent pour des microbes. 



   Le désavantage d'un pareil   enballage   consiste dans le fait que la viande est tenue   continuellenent     nouillée   et que la belle couleur de celle-ci est décomposée systématiquement au fur et à mesure, ce qui provoque un changement de couleur de la viande et de la graisse. La graisse, dans ces conditions devient rose, ce qui est un désavantage pour la vente et pour la consommation. 



   Le suc cellulaire contient, entre   autr,   des colorants naturels de la   viande,   des sels et de l'albunine. La pression osmotique de ce suc cellulaire est telle qu'il est   impossible   que celui-ci puisse de nouveau pénétrer dans les cellules de la viande . 



   La présente invention a pour but de remédier à ces in- convénients et concerne, à cet effet, un emballage à vide d'air pour la viande fraîche et   consolée,   formé d'une feuille on plastique imperméable et transparente, caractérisé par le fait que la viande à   emballer   est posée sur une couche hydro- ,hile dont la capillarité est moins grande que la pression esmotique du suc cellulaire de la viande, 
Une couche hydrophile dont la capillarité est moins grande que la pression   osmotique   du suc cellulaire de la viande absorbe pendant l'emmagasinage autant de suc cellulaire jusqu'à ce que sa capillarit6 soit   zéro, A   ce Moment il existe un équilibre osmotique entre la couche hydrophile, d'une part, et la viande se trouvant sur cette couche hydrophile, d'autre part,

   de   faon   qu'il n'y ait plus de perte en suc cellulaire de la viande. 



   Il a été trouvé que le carton se prête très bien comme couche hydrophile. Pour 1 kg de viande fraîche, il faut 30,3 gr de carton, tandis que, pour 1 kg de viande congelée, il en faut 40,4   r,   Hn dégelant la viande congelée, celle-ci peut être

   L'emballage décrit est plus attractif pour la vente et la qualité de la viande est meilleure.

  "Vacuum packaging for fresh and frozen meat".



   It is known that fresh meat, like also thawed meat, is packaged piece by piece in a transparent plastic bag and that the whole is evacuated in order to then be formed horméjtically. These packages are then stored in a refrigeration unit to be sold later, which can take some time,
By slicing the meat, the muscle cells, also the cell membranes, are injured so that the cell juice exits the cells and accumulates at the bottom of the package.



   The more the meat is sliced into small pieces, the more: the cellular juice accumulates in the packaging. This cellular juice

 <Desc / Clms Page number 2>

 presents an excellent medium for germs.



   The disadvantage of such a wrapping is that the meat is kept constantly knotty and the beautiful color of it is systematically broken down over time, causing a change in color of the meat and fat. . The fat under these conditions turns pink, which is a disadvantage for sale and for consumption.



   Cellular juice contains, among others, natural meat dyes, salts and albunin. The osmotic pressure of this cellular juice is such that it is impossible for it to reenter the cells of the meat.



   The object of the present invention is to remedy these drawbacks and relates, to this end, to an air-vacuum packaging for fresh and consoled meat, formed from an impermeable and transparent plastic sheet, characterized in that the meat to be packaged is placed on a hydrophilic layer, the capillarity of which is less than the esmotic pressure of the cellular juice of the meat,
A hydrophilic layer whose capillarity is less than the osmotic pressure of the cell juice of the meat absorbs during storage as much cell juice until its capillarity is zero. At this time there is an osmotic balance between the hydrophilic layer , on the one hand, and the meat on this hydrophilic layer, on the other hand,

   so that there is no more loss of cellular juice from the meat.



   It has been found that cardboard lends itself very well as a hydrophilic layer. For 1 kg of fresh meat you need 30.3 gr of cardboard, while for 1 kg of frozen meat you need 40.4 r, Hn thawing the frozen meat, it can be

 dry out of its packaging,
 EMI3.1
 The advantages of a crballare according to the present invention are that the meat can be fed in a dry and not wet manner. In this way, hygienic and favorable conditions are created which have never been achieved until now. The meat, like also the fat, retain their beautiful initial color.



   The packaging described is more attractive for sale and the quality of the meat is better.
