Definitions

  • the invention relates to a process for the preparation and packaging of food products and / or preparations, aiming in particular to bring together the different ingredients of a cooked dish in the same packaging offering guarantees of prolonged storage, at room temperature.
  • the invention also relates to a packaging of such food products or preparations, ensuring such preservation.
  • the invention makes it possible to combine the advantages of the two modes of preservation analyzed above, without suffering from their disadvantages.
  • One of the aims of the invention is to allow the preparation and packaging of products and / or food preparations making it possible to prepare complete cooked dishes having high organoleptic and gastronomic qualities.
  • Another object of the invention is to allow the storage of such packages at room temperature.
  • Another object of the invention is to propose a method of packaging whose cost price is comparable to that of frozen products, for negligible storage costs.
  • Another object of the invention is to propose a method of packaging with a long shelf life.
  • the invention relates to a process for the preparation and packaging of food products and / or preparations, characterized in that it consists in packaging, preferably under vacuum, in relatively impermeable flexible envelopes, products or preparations different foodstuffs, to be cooked and / or to be sterilized, under possibly specific conditions, at least some of the said foodstuffs in their respective flexible envelopes, and to enclose several flexible envelopes with different contents in a rigid and hermetically sealed overwrap.
  • the oxygen in said overpack is substantially eliminated, for example by creating a vacuum therein on closing and / or by introducing a neutral gas therein.
  • Said overpack is preferably essentially metallic.
  • the invention also relates to a packaging for food products and / or preparations characterized in that it consists of several relatively impermeable flexible envelopes, containing separate food products or preparations and of a hermetically sealed rigid overpack, enclosing said flexible envelopes.
  • the said flexible envelopes can be made of a very common material and of low cost, for example from an ordinary plastic film, monolayer, polypropylene. Indeed, this flexible envelope must simply withstand the cooking-sterilization treatment (that is to say essentially withstand a temperature of the order of 125 ° C.) and have sufficient impermeability to preserve the food from contamination. later.
  • the fact that the envelope is transparent also allows immediate identification of the various constituents, without the need for labeling.
  • composite films can be used, in particular with several layers of materials, for example including a metallic layer (aluminum) forming an additional barrier to oxygen.
  • the overpack if it is metallic (which will be the preferred solution in the vast majority of cases) can be of a simple design and a lower degree of finish than the metallic packaging with which food products are in direct contact. This is how the interior varnish will generally no longer be necessary and even tinning in some cases. Consequently, the combination of flexible envelopes and overpack, simpler and less costly considered separately (monolayer envelope of common plastic material on the one hand and metal packaging without special treatment on the other hand) makes it possible to limit the costs of packaging and make the final product very competitive compared to a frozen product. As mentioned above, substantial savings are made on storage costs since this storage can be carried out at room temperature and without any special precautions, exactly as if it were traditional cans.
  • the preparation of the vegetables will preferably include the following operations: - The vegetables are first "blanched" which means that they are immersed for a few minutes in boiling water. - Rations of such vegetables are then introduced into flexible polypropylene envelopes, transparent, forming sachets. - We then proceed to the evacuation and closure of these bags, by heat sealing. - The sachets are then sterilized at 120 ° C for about 15 minutes. - The bags are then subject to controlled cooling.
  • the invention makes it possible, among other things, to optimize the sterilization and cooling operations, as a function of the product which is in the sachets.
  • the packaging of FIG. 1 comprises several flexible envelopes 12, 13, 14 forming transparent plastic bags and a single rigid over-packaging 16, hermetically closed, containing said flexible envelopes.
  • the latter were sealed under vacuum and underwent a sterilization treatment as indicated above.
  • the envelope 12 may, for example, contain meat or fish, the envelope 13 of the vegetables and the envelope 14 a sauce, all of these ingredients being assorted to make it possible to constitute a given cooked dish.
  • the flexible envelopes 12, 13 and 14 are relatively impermeable in the sense that they at least allow food to be kept in their sterilized state, avoiding recontamination.
  • the plastic material used typically a polypropylene film
  • the overpack is a can of conventional type in the canning industry, that is to say with a cylindrical and tubular can body, a bottom and a cover, the latter being attached by crimping, hermetically closing the box.
  • a cylindrical and tubular can body that is to say with a cylindrical and tubular can body, a bottom and a cover, the latter being attached by crimping, hermetically closing the box.
  • the closure of the box is gas tight to properly conserve the vacuum or the neutral gas. It is not essential that the overpack is tinned, even less that it is internally varnished or covered with any coating.
  • the presentation is different from the fact that the flexible envelopes 12, 13, 14 are, this time, placed in an overpack in the form of a "tray" 16 a , closed by a cover 19 a .
  • Said tray 16 is a rigid metal.
  • the cover 19 a can also be a sheet cover crimped at the edge of the opening of the tray. It may also be, as shown, a relatively flexible said cover “peelable” reported by heat sealing or any other known sealing means, on a flat rim 21 of said tray, extending along its opening.
  • This embodiment allows the overpack to be opened without the aid of any tool.
  • the flexible cover will take a slightly concave shape under the effect of the vacuum, which will allow to verify in another way the conformity of the product, when purchased.
  • the overpack can also be filled with a neutral gas preserving from any long-term oxidation.
  • the tray 16b is substantially the same as in Figure 2, but the cover 19b is made of rigid metal and it is provided with a seal 22 which rests on the rim flat 21.
  • the maintenance of the cover is essentially ensured by the presence of the depression in the overpack, maintaining said cover in application by its seal, against said flange.
  • the opening can be done easily by piercing the cover.
  • the cover 19 c made of sheet metal, is attached to the box body 16 c by a simple "roll" 25 of the edges to be assembled, which avoids a complete crimping as in the embodiment. of Figure 1.
  • the cover (or the edge of the box body) advantageously comprises a seal 26 of elastomeric material, bonded in the vicinity of the edge of said cover.
