Definitions

• the present invention relates to a packaging and a method for packaging crustaceans of the shrimp, lobster, crayfish, lobster and crab type in raw or cooked form, and more particularly in frozen or refrigerated form.
• the present invention also relates to said crustaceans conditioned under vacuum, at least under partial vacuum, using a package according to the invention, said conditioned crustaceans being optionally frozen or refrigerated.
• the present invention also relates to a process for cooking crustaceans of the shrimp or langoustine type and more particularly to a process for cooking crustaceans packaged in a package according to the invention.
• the present invention applies more particularly to the packaging of edible aquatic crustaceans such as crabs, shrimps, crayfish, lobsters, lobsters and lobsters.
• the present invention applies to crustaceans marketed in non-shelled form and more particularly still to shrimps of tropical origin such as prawns. Mention is made in particular of monodom or styriostris shrimps which do not require colorants for cooking to become red.
• the product loses its traceability as to its date of production and the origin of the product such as the identification of the breeding basin or the fishing basin, in the event of farming the identification of feed and broodstock where appropriate;
• the product is fragile by nature and handled several times, in naked form and without protection, in packaging and deconditioning operations, which risks degrading the quality of the product;
• the aim of the present invention is to provide a packaging and if necessary cooking process for crustaceans making it possible to market raw or cooked crustaceans from the production site to the point of sale or even the place of consumption by the final consumer, in the same original packaging, thus making it possible more particularly to market in its original packaging shrimp in the form of chilled cooked shrimp or in the form of frozen frozen shrimp.
• Packaging and cooking methods are known for marketing original food products raw or cooked animal from the production site to the place of sale or consumption, all stages of transformation, cooking and transport being carried out with the product kept in its original packaging. These are more particularly meat products, cooked ready meals and dairy products.
• the food product of animal origin must be vacuum-packed in a flexible plastic film which follows the outline of the product, this tiny contact being ensured by a vacuum allowing the film to adhere to the product.
• This vacuum to obtain intimate contact between the packaging and the product aims to increase the heat exchange between the product and the heat transfer fluid outside the packaging such as hot air or water on the one hand, and on the other hand makes it possible to increase the deadline for sale or consumption of the product without using packaging in an atmosphere of neutral or inert gas.
• a vacuum packed product cannot be polluted by aerobic bacteria contained in the air. So after cooking the lack of oxygen around the product increases the date of D.L.V. Ideal for conservation would be a Total vacuum. On the other hand, it could be that for aesthetic reasons of conditioning after cooking it is necessary to have only a partial vacuum to the detriment of the D.L.V.
• the other way to increase the D.L.V. is to replace the ambient air of the tray with an inert gas, (with or with little oxygen), after cooking.
• the flexible film is necessary because during cooking, the water inside the product generates an increase in the water vapor pressure. This vapor pressure partially decreases when the product cools after cooking. Films are known in particular from flexible plastic material capable of withstanding the vapor pressure due to the presence of water in the products during cooking under vacuum. These flexible films return to their initial shape after curing but do not withstand mechanical stresses up to 100 ° C. This flexible synthetic film is applied to a rigid tray-type support by perfect welding at the upper periphery of said tray.
• the present invention provides a packaging, method for packaging crustaceans, in particular shrimp, which makes it possible to condition said crustaceans at their place of production and to keep the original packaging until the place of marketing, or even of consumption, preserving the integrity of said conditioning.
• the present invention provides a packaging containing fresh crustaceans, preferably frozen, ready to cook in said packaging, said crustaceans being stored.
