Description

Procédé de conditionnement et conditionnement pour la conservation et/ou la cuisson ou le réchauffage de produits alimentaires. Packaging method and packaging for the preservation and / or cooking or reheating of food products.
La présente invention concerne un procédé de conditionnement et un conditionnement pour la conservation et/ou la cuisson ou le réchauffage de produits alimentaires. Selon une application plus particulièrement intéressante, quoique nullement limitative, le procédé et le conditionnement selon l'invention sont destinés à permettre la conservation et la cuisson ou le réchauffage, par vapeur saturante à l'aide d'un micro-ondes, de tous produits alimentaires frais, tels que légumes ou fruits crus ou précuits ou produits alimentaires cuisinés divers.The present invention relates to a packaging method and a packaging for the preservation and / or cooking or reheating of food products. According to a more particularly advantageous application, although in no way limiting, the method and the packaging according to the invention are intended to allow the preservation and cooking or reheating, by saturated steam using a microwave, of all products fresh food, such as raw or pre-cooked vegetables or fruit or miscellaneous cooked food products.
De nombreux produits alimentaires tels que certains légumes ou fruits frais ou précuits, ou certains plats cuisinés, sont commercialisés dans des barquettes en matière plastique recouvertes par un film rétractable, par exemple exécuté en polyéthylène ou analogue, avec des instructions préconisant, le cas échéant, les modalités de leur cuisson ou de leur réchauffage dans un four à micro-ondes. Ce mode de conditionnement présente au moins deux inconvénients, à savoir : - un risque de déshydratation accélérée des produits alimentaires si les barquettes de ces produits ne sont pas conservées dans les conditions les plus favorables de température et d'hygrométrie ; - un risque de dessiccation avancée lors de leur passage dans le microondes altérant la consistance, les qualités organoleptiques et les vitamines des produits.Many food products such as certain fresh or precooked vegetables or fruits, or certain cooked dishes, are sold in plastic trays covered with a shrink film, for example made of polyethylene or the like, with instructions recommending, where appropriate, how to cook or reheat them in a microwave. This packaging method has at least two drawbacks, namely: - a risk of accelerated dehydration of food products if the trays of these products are not stored under the most favorable conditions of temperature and hygrometry; - a risk of advanced desiccation during their passage in the microwave altering the consistency, the organoleptic qualities and the vitamins of the products.
On connaît (EP-701995A, EP-732275A) un dispositif pour le conditionnement et la conservation de produits alimentaires frais tels que viandes, poissons ou analogues, tendant à exsuder des liquides favorisant ta prolifération des flores bactériennes qui en limitent ainsi la durée de consommation autorisée, ce dispositif étant constitué par une barquette de matière plastique comportant un fond imperméable et un faux fond présentant des perforations, disposé au-dessus et à distance du fond, un tampon absorbant étant disposé entre ledit fond et ledit faux fond, ce tampon absorbant contenant un inhibiteur chimique de neutralisation des émanations des produits, et éventuellement d'autres agents tels qu'un réactif de régénération capable de modifier l'atmosphère de confinement desdits produits, en fonction de leurs émanations.There is known (EP-701995A, EP-732275A) a device for packaging and preserving fresh food products such as meats, fish or the like, tending to exude liquids promoting the proliferation of bacterial flora which thus limit the duration of consumption. authorized, this device being constituted by a plastic tray comprising an impermeable bottom and a false bottom having perforations, disposed above and at a distance from the bottom, an absorbent pad being arranged between said bottom and said false bottom, this absorbent pad containing a chemical inhibitor for neutralizing product fumes, and possibly other agents such as a regeneration reagent capable of modifying the confinement atmosphere of said products, depending on their fumes.
Si un tel dispositif peut résoudre le problème du traitement des exsudats libérés par les produits alimentaires d'origine animale tels que tripes, pièces de viandes, poissons, etc., il ne résout pas le problème précédemment exposé de conservation et/ou de cuisson ou de réchauffage, par vapeur saturante, des produits tels que légumes frais, préparations cuisinées ou analogues, par passage au micro-ondes, lié au phénomène de déshydratation de ces produits. L'invention se propose donc de résoudre ce problème spécifique.If such a device can solve the problem of the treatment of exudates released by food products of animal origin such as tripe, pieces of meats, fish, etc., it does not solve the previously exposed problem of preservation and / or cooking or reheating, by saturated steam, of products such as fresh vegetables, cooked preparations or the like, by passing through the microwave, linked the phenomenon of dehydration of these products. The invention therefore proposes to solve this specific problem.
Selon l'invention, ce but est atteint grâce à un procédé de conditionnement et à un conditionnement suivant lesquels les produits alimentaires sont logés dans un emballage hermétiquement clos comprenant un récipient ou barquette comportant un fond imperméable et un faux fond muni de perforations, disposé au-dessus et à distance du fond, un tampon saturateur ou humidificateur imbibé d'eau, additionnée ou non d'un agent de traitement, étant placé entre ledit fond et ledit faux fond, le récipient ou barquette étant fermé par un film plastique soudé sur la périphérie dudit récipient.According to the invention, this object is achieved thanks to a packaging process and to a packaging according to which the food products are housed in a hermetically sealed package comprising a container or tray having an impermeable bottom and a false bottom provided with perforations, arranged at the above and at a distance from the bottom, a saturator or humidifier pad soaked in water, with or without the addition of a treatment agent, being placed between said bottom and said false bottom, the container or tray being closed by a plastic film welded onto the periphery of said container.
Selon une autre disposition caractéristique de l'invention, l'emballage c'est-à- dire la barquette et le film de fermeture sont exécutés dans des matériaux transparents aux micro-ondes et résistant à la chaleur dégagée par les fours à micro-ondes, lors de leur utilisation.According to another characteristic arrangement of the invention, the packaging, that is to say the tray and the closure film, are made of materials transparent to microwaves and resistant to the heat given off by microwave ovens. , when in use.
Le procédé et le conditionnement selon l'invention procurent plusieurs avantages : - ils évitent une dessiccation accélérée des produits alimentaires frais durant la période comprise entre leur emballage et leur consommation ;The method and packaging according to the invention provide several advantages: - they prevent accelerated drying of fresh food products during the period between their packaging and their consumption;
- ils apportent une amélioration importante de la durée de vie des produits conditionnés, grâce à la régulation qui s'opère naturellement à l'intérieur du récipient suivant un principe de photosynthèse (oxygène + eau + lumière) ;- they bring a significant improvement in the life of the packaged products, thanks to the regulation which takes place naturally inside the container according to a photosynthesis principle (oxygen + water + light);
- ils permettent une cuisson ou un réchauffage rapides, sans déshydratation des produits frais, crus, précuits ou cuisinés, par exemple conditionnés en portions de 50 g à 1 kg ;- they allow rapid cooking or reheating, without dehydrating fresh, raw, precooked or cooked products, for example packaged in portions of 50 g to 1 kg;
- ils permettent d'obtenir une meilleure conservation des qualités organoleptiques, des vitamines et des saveurs contenues dans les produits. Les buts, caractéristiques et avantages ci-dessus, et d'autres encore, ressortiront mieux de la description qui suit et du dessin annexé, dans lequel :- they allow better preservation of the organoleptic qualities, vitamins and flavors contained in the products. The aims, characteristics and advantages above, and others still, will emerge more clearly from the description which follows and from the appended drawing, in which:
- la figure 1 est une demi vue en coupe longitudinale et à échelle agrandie, d'un conditionnement exécuté selon l'invention ;- Figure 1 is a half view in longitudinal section and on an enlarged scale, of a packaging executed according to the invention;
- la figure 2 est une vue avec arrachements partiels, en plan et en coupe selon la ligne 2-2 de la figure 1. On se réfère audit dessin pour décrire un exemple intéressant, bien que nullement limitatif, de mise en œuvre du procédé de conditionnement et de réalisation du conditionnement selon l'invention.- Figure 2 is a view with partial cutaway, in plan and in section along line 2-2 of Figure 1. Reference is made to said drawing to describe an interesting example, although in no way limitative, of implementation of the packaging process and production of packaging according to the invention.
Dans l'exposé qui suit, on précise que le mot "conditionnement" lorsqu'il n'est pas utilisé comme complément de nom dans l'expression "procédé de conditionnement", désigne un article constitué par un emballage et le produit alimentaire contenu dans celui-ci.In the description which follows, it is specified that the word "packaging" when it is not used as an additional name in the expression "process of conditioning", designates an article consisting of a packaging and the food product contained in this one.
Ce conditionnement comprend un récipient ou barquette 1 munie d'un double fond constitué d'un fond 2, de préférence imperméable à l'eau, et d'un faux fond 3 disposé au-dessus et à distance de ce fond. Le faux fond 3 est pourvu d'une pluralité de perforations 4, par exemple de forme circulaire, et, de préférence, régulièrement espacées et réparties sur la totalité de la surface dudit faux fond.This packaging includes a container or tray 1 provided with a double bottom consisting of a bottom 2, preferably waterproof, and a false bottom 3 disposed above and at a distance from this bottom. The false bottom 3 is provided with a plurality of perforations 4, for example of circular shape, and, preferably, regularly spaced and distributed over the entire surface of said false bottom.
Le récipient 1 est, par exemple constitué par une double coque comprenant une coque externe 5 comportant le fond 2 et une coque interne 6 de dimensions plus réduites comportant le faux fond perforé 3 et emboîtée dans ladite coque externe 5.The container 1 is, for example constituted by a double shell comprising an outer shell 5 comprising the bottom 2 and an inner shell 6 of smaller dimensions comprising the false perforated bottom 3 and fitted into said outer shell 5.
Compte tenu de l'application intéressante du procédé et du conditionnement de l'invention à la commercialisation de produits destinés à être cuits ou réchauffés à l'aide d'un micro-ondes, la barquette 1 et, par conséquent, selon l'exemple illustré, les coques externe 5 et interne 6 peuvent être exécutées dans tous matériaux transparents aux micro-ondes, imperméables à l'eau et capables de résister à la chaleur dégagée par les fours à micro-ondes conçus pour la cuisine, lors de l'utilisation de ces fours, c'est-à-dire, pratiquement, à une chaleur au moins égale à 100°C, en entraînant aucune déformation ni migration de leurs composants vers les aliments ou l'eau contenue dans le conditionnement. Les coques sont, par exemple, thermoformées en toute matière plastique alimentaire semi-rigide remplissant les exigences susmentionnées, telle que, par exemple, en polypropylène (PP). Les coques externe 5 et interne 6 peuvent être rendues solidaires l'une de l'autre, par tout procédé convenable, par exemple au moyen d'une opération de thermo-soudage, au niveau du bord supérieur des parois périphériques desdites coques ou par l'intermédiaire de leurs fonds dont l'un comporte, dans ce cas, des nervures permettant ce soudage et le maintien d'un espace entre lesdits fonds 2 et 3.Given the advantageous application of the method and the packaging of the invention to the marketing of products intended to be cooked or reheated using a microwave, the tray 1 and, consequently, according to the example illustrated, the outer 5 and inner 6 shells can be made of any material that is transparent to microwaves, waterproof and capable of withstanding the heat given off by microwave ovens designed for cooking, when use of these ovens, that is to say, practically, at a heat at least equal to 100 ° C., causing no deformation or migration of their components towards the food or the water contained in the packaging. The shells are, for example, thermoformed from any semi-rigid food plastic material fulfilling the above-mentioned requirements, such as, for example, polypropylene (PP). The outer 5 and inner 6 shells can be made integral with one another, by any suitable method, for example by means of a heat-welding operation, at the upper edge of the peripheral walls of said shells or by the 'intermediate of their bottoms, one of which in this case includes ribs allowing this welding and the maintenance of a space between said bottoms 2 and 3.
De manière connue en soi, les coques 5 et 6 constituant le récipient ou barquette rigide 1 peuvent comporter des nervures assurant leur rigidité. Dans l'espace E ménagé entre le fond 2 et le faux fond 3, est disposé un tampon saturateur ou humidificateur 7 occupant, de préférence, la totalité ou la quasi totalité dudit espace.In a manner known per se, the shells 5 and 6 constituting the rigid container or tray 1 may include ribs ensuring their rigidity. In the space E formed between the bottom 2 and the false bottom 3, is arranged a saturator or humidifier pad 7 occupying, preferably, all or almost all of said space.
Ce tampon humidificateur 7 est constitué par une plaque de matière spongieuse, par exemple du genre buvard alimentaire, imbibée d'eau. Cette plaque spongieuse peut être constituée par un non tissé de fibres d'origine végétale, animale ou synthétique. De manière avantageuse, le poids du volume d'eau retenu dans le tampon humidificateur est de 40 à 60 fois supérieur au poids dudit tampon à l'état non imprégné. L'eau imprégnant la plaque de matière spongieuse peut être additionnée d'au moins un agent de traitement des produits alimentaires 8 logés dans l'emballage 1-9, tels que, par exemple, un agent de conservation, un agent chimique ou naturel d'aromatisation, etc.This humidifier pad 7 consists of a plate of spongy material, for example of the food blotter type, soaked in water. This spongy plate can be constituted by a nonwoven of fibers of vegetable, animal or synthetic origin. Advantageously, the weight of the volume of water retained in the humidifying pad is 40 to 60 times greater than the weight of said pad in the non-impregnated state. The water impregnating the plate of spongy material may be added with at least one food processing agent 8 housed in the packaging 1-9, such as, for example, a preservative, a chemical or natural agent d flavoring, etc.
Les produits alimentaires frais 8 tels que légumes ou fruits crus ou précuits, préparations cuisinées ou autres, sont logés dans le récipient ou barquette 1 et maintenus dans celle-ci au moyen d'une pellicule ou film transparent 9 fixé par soudage thermique, par exemple sur le pourtour du bord supérieur de ladite barquette. Ce film transparent peut être réalisé en toute matière plastique présentant les qualités requises pour la réalisation du conditionnement et pour la cuisson ou le réchauffage des denrées alimentaires, telles que transparence à la lumière et aux micro-ondes, souplesse, extensibilité, rétractabilité. conformité à la réglementation alimentaire, résistance aux chaleurs dégagées par les microondes, résistance à la pression générée par la vapeur située dans l'enceinte du récipient lors de la cuisson, perméabilité à l'air (permettant aux produits frais de respirer sans contact direct avec l'air ambiant leur évitant ainsi l'asphyxie et une dégradation prématurée).The fresh food products 8 such as raw or precooked vegetables or fruits, cooked preparations or the like, are housed in the container or tray 1 and kept therein by means of a transparent film or film 9 fixed by thermal welding, for example on the periphery of the upper edge of said tray. This transparent film can be made of any plastic material having the qualities required for carrying out the packaging and for cooking or reheating foodstuffs, such as transparency to light and to microwaves, flexibility, extensibility, retractability. compliance with food regulations, resistance to heat released by microwaves, resistance to pressure generated by the steam located in the enclosure of the container during cooking, air permeability (allowing fresh products to breathe without direct contact with ambient air thus preventing them from suffocation and premature deterioration).
Le film transparent 9 peut, par exemple, être exécuté en polyéthylène ou en polyéthylène téréphtalate (PET), et, plus précisément et de préférence, en polyoléfine rétractable anti-buée, à structure multicouches coextrudées. Le conditionnement réalisé selon l'invention est préparé par les expéditeurs de légumes ou fruits crus ou précuits ou par les industriels qui confectionnent des plats cuisinés, en amont des circuits de ventes aux consommateurs, de sorte que les produits ainsi conditionnés sont maintenus jusqu'à leur consommation, dans un environnement spécifique présentant une hygrométrie qui retarde le processus de dessiccation desdits produits.The transparent film 9 can, for example, be made of polyethylene or polyethylene terephthalate (PET), and, more precisely and preferably, in retractable anti-fog polyolefin, with a coextruded multilayer structure. The packaging produced according to the invention is prepared by shippers of raw or precooked vegetables or fruits or by manufacturers who prepare ready meals, upstream of the sales channels to consumers, so that the products thus conditioned are kept until their consumption, in a specific environment with a humidity which delays the drying process of said products.
D'autre part, lorsque le conditionnement est placé dans un four à microondes, en vue de la cuisson ou du réchauffage du produit alimentaire qu'il renferme, l'eau contenue dans le tampon saturateur ou humidificateur 7 se transforme rapidement en vapeur. Cette vapeur s'échappe par les trous 4 ménagés dans le faux fond 3 du récipient 1 et vient occuper l'ensemble du volume délimité par ledit récipient et le film de fermeture 9.On the other hand, when the packaging is placed in a microwave oven, for the purpose of cooking or reheating the food product which it contains, the water contained in the saturator or humidifier pad 7 is rapidly transformed into vapor. This vapor escapes through the holes 4 formed in the false bottom 3 of the container 1 and occupies the entire volume delimited by said container and the closure film 9.
Le principe de la cuisson par micro-ondes agit ainsi simultanément sur les produits solides et l'eau contenus dans l'emballage, en créant les conditions idéales pour une cuisson ou un réchauffage par vapeur saturante, en évitant ainsi toute déshydratation desdits produits.The principle of microwave cooking thus acts simultaneously on the solid products and the water contained in the packaging, creating the ideal conditions for cooking or reheating with saturated steam, thus avoiding any dehydration of said products.
Afin d'éviter toute surpression conduisant à une déformation non désirable du récipient, lors de la cuisson, une perforation 10 est prévue dans le film de fermeture 9. Cette perforation est exécutée lors de la réalisation du conditionnement. Pour prévenir tout contact des produits avec l'air ambiant, une pastille ou étiquette alimentaire operculaire détachable 11 est collée sur la perforation après réalisation du conditionnement, afin d'obturer ladite perforation.In order to avoid any excess pressure leading to an undesirable deformation of the container, during cooking, a perforation 10 is provided in the closure film 9. This perforation is carried out during the production of the packaging. To prevent any contact of the products with the ambient air, a detachable opercular pastille or food label 11 is stuck on the perforation after completion of the packaging, in order to close said perforation.
Cette pastille operculaire détachable est retirée par le consommateur avant de passer le conditionnement au micro-ondes. This detachable seal is removed by the consumer before placing the packaging in the microwave.
