Definitions
- the present invention relates to the field of preservation of packaged food products: for example under vacuum or in a protective atmosphere, the two methods being sometimes combined, in particular for meat products.
- the vacuum packaging method is known to extend the shelf life of foods. It consists in placing the product in an airtight packaging, sucking the air contained in the packaging and sealing or "sealing" the latter (it is known that the term “sealing” is used mainly for bags and flexible packaging, while that in the case of trays or rigid packaging we speak rather of sealing).
- Eliminating the air surrounding the product reduces the level of oxygen present in the package and thus prevents aerobic microorganisms from developing and degrading the food.
- the absence of oxygen also reduces degradation due to oxidation (the process that causes, for example, the browning of bananas and apples).
- the "presentation” obtained is such that the film is “plated” on the food product during the evacuation to create a "second skin” effect by the vacuum of air and marry perfectly the contours of the product.
- the top film is heated in one or more steps to utilize the thermoelastic properties of the polymers.
- the lower support of the product and the upper film are sometimes heat-sealed, thus ensuring a good security of sealing.
- the upper film exerts a significant force on the food product which can generate a deformation of the latter.
- the evacuation generates deformations produced, crushes (examples: fruits, meat, fish etc ).
- crushes examples: fruits, meat, fish etc .
- the visual appearance of the products thus packaged is then a brake on the marketing or requires an overpack.
- the present invention thus aims to propose a technical solution to the difficulties listed above, and in particular to propose a solution to ensure the maintenance of the shape of the products, to ensure better control of the color of the products packaged under vacuum and a better control of the recovery in color during the return to the air (with opening of the packing).
- the solution proposed by the present invention lies in the fact of “stiffening” the products on the surface and for this, “stiffening” or “surface crusting” by the cold is carried out .
- the invention thus relates to a vacuum packaging method for food products, where:
- the product is positioned in a package
- a crusting operation is carried out on the surface of the product by supplying cryogenic cold (freezing on the surface of the product by supplying cryogenic cold).
- cryogenic cold freezing on the surface of the product by supplying cryogenic cold.
- a mixture of gases for example a 02 / CO 2 mixture or a mixture based on nitrogen
- these packages are mainly used for fresh meat products, particularly beef, pork, veal and lamb and all the proteins whose color is disturbed by lack of oxygen, but other applications are mentioned as salting products, fish and seafood, poultry, cheese and other prepared dishes.
- liquid nitrogen or liquid CO2 is according to the present preferred invention, the CO2 also having recognized bacteriostatic effects.
- a cryogenic tunnel such as those commonly used in the food industry makes it possible to provide such a cold supply.
- cryogenic tunnels are adapted to achieve rapid and controlled crusts, and in particular the fact that a short passage time (for example 1 to 5 minutes), coupled with very low temperatures , typically from -30 to -140 ° C., makes it possible to reach crusting thicknesses (hardening or stiffening) making it possible to preserve the integrity of the product, without having to pass the threshold for changing the state of the water of the product. product.
- a crusting thickness of 1 to 3 mm gave very satisfactory results on all the products tested.
- a cold room tempering step during a period of 8 to 12 hours, during which a core temperature of -2 to -4 ° C is reached, which means a freezing at heart;
- the document proceeds, prior to the positioning of the product in the package, to a crusting operation on the surface of the product by adding cryogenic cold, followed by freezing to the core.
