Definitions
- the present invention relates to a steam generator device more specifically intended to be introduced into a packaging for heating or cooking, in particular microwaves of foodstuffs.
- microwave ovens Since their appearance on the market, microwave ovens have been very popular with consumers and many households have one.
- microwave ovens allow very rapid cooking or reheating of foodstuffs since the internal layers of these directly collect radiated electromagnetic energy and this energy is available immediately, without requiring time latency for the temperature rise of the oven.
- controlling the thermal profile in a microwave-heated environment is complex because there are interactions between the thermal fields and the electromagnetic fields, as well as an influence of the oven enclosure, of the product introduced into this and the generator; consequently heating in the microwave cannot in practice make it possible to obtain a quality of cooking comparable to that obtained in a traditional oven.
- the rise in temperature is consecutive to phenomena of infrared radiation, conduction and convection, and the thermal energy absorbed by the surface layers of the food product to be heated diffuses towards the inner layers of it.
- microwave heating results in thermal heterogeneity resulting from a non-uniform distribution of the energy dissipated and absorbed in the heated product which cannot be compensated during heating by the diffusion of heat.
- the second drawback is related to the fact that the heterogeneous distribution of the electromagnetic waves leads to the presence of "hot” points and “cold” points whose distribution, very variable, depends at the same time on the furnace (dimensioning of the cavity, structure and positioning of the radiating element, etc.) and of the product to be heated (composition, temperature, shape, volume, packaging, position in the oven, etc.).
- the instability of heating in a microwave oven is also due to coupling phenomena between the food product to be heated, the oven cavity and the generator.
- the power actually absorbed by this product depends on the load represented by the assembly made up of it and the oven enclosure, which acts on the reflection of the waves towards the generator and on the power emitted by the latter.
- Microwave thermal is further distinguished from conventional thermal by the inversion of the thermal gradient in the mass of the heated product which results in an inversion of the direction of migration of water; however, as it is the food product which heats the oven, the water always presents difficulties in evaporating so that the periphery of this product always remains wet while its internal part dries up.
- the tray must be modified to allow the placement of the pad (addition of a double bottom and placement of the pad in the humidification chamber delimited by it);
- the tampon must be placed in the tray during its manufacture
- the object of the present invention is to remedy these drawbacks by proposing a device for generating steam which can be introduced into any type of packaging at the same time as the foodstuffs to be packaged, and in parallel. likely to trap a very large amount of water which can be restored by simple heating in the form of water vapor.
- This device is characterized in that it consists of a packaging, in particular by a sachet made of a material at least partially porous with steam containing a gel capable of rapidly absorbing microwaves, this gel containing a weight part of hydrocolloid, corresponding to its dry form, for at least 10 weight parts of water.
- hydrocolloid means the dry form of such a gel.
- the hydrocolloid is therefore capable of fixing a large quantity of water in the form of a gel and of restoring it in the form of vapor following reheating caused in particular by microwaves.
- the viscosity of this gel is at least equal to 2 to 3 ICA Pa.s.
- the formation of the gel is consecutive to a physical reaction making it possible to retain water within a three-dimensional network formed by the hydrocolloid molecules.
- the water consequently loses all freedom and is therefore trapped and, so to speak, "masked" by the three-dimensional network.
- the concentration of the hydrocolloid within the gel so as to be as far as possible from the saturation limit and to avoid leaching as much as possible, thus making it possible to improve the water retention power.
- the device according to the invention if it is particularly suitable for heating or cooking in a microwave oven, can also be introduced into a packaging for heating foodstuffs by means of a thermal oven ...
- the hydrocolloid can be chosen from natural molecules such as alginates, carrageenans or guar gum.
- the hydrocolloid can be chosen from cellulose derivatives such as carboxymethylcellulose or ethylcellulose.
- the hydrocolloid can be chosen from super-absorbents of synthesis, such as the salts of polyacrylic acids which absorb at least 7 times more water per gram than blotters and up to about minus 50 times their weight of water.
- the super absorbent which can be used in accordance with the invention corresponds to a crosslinked compound having a variable particle size which can be situated in a range from the micrometer to several millimeters.
- the water added to this hydrocolloid to allow the formation of the gel can if necessary be spring water, in particular in the case of the use of a natural hydrocolloid, in particular when the quality of the water available on the premises packaging of the food product is questionable, and unsuitable for reassuring consumers.
- This water can also, where appropriate and without departing from the scope of the invention, be supplemented with ingredients such as perfumes, aromas, or volatile natural extracts capable of exhibiting various activities on the flavor or preservation of the food product ( bacteriostatic or fungistatic; essential oils or oleoresins) or on the health and well-being of consumers.
- ingredients such as perfumes, aromas, or volatile natural extracts capable of exhibiting various activities on the flavor or preservation of the food product ( bacteriostatic or fungistatic; essential oils or oleoresins) or on the health and well-being of consumers.
- the amount of gel contained in the sachet is in each case a function of the amount of water vapor desired and the duration of production of this desired vapor.
- the porosity of the bag must be sufficient to allow rapid evacuation of the water vapor generated under the effect of microwaves, without the risk of bursting of this bag.
- this porosity must as a rule be greater than 1500 ml / minute measured with the Bendtsen porosimeter. It is also necessary to ensure that the material constituting the sachet resists the temperature following the heating of the gel under the action of microwave radiation.
- this material may for example consist of a nonwoven material in particular based on polyethylene or better still on polypropylene.
- this material can be treated by adding a surfactant approved for food contact, in particular from the family of silicone derivatives, as an example of polydimethylsiloxanes, in such a way as to make it hydrophilic and to accelerate the transfer of water.
- a surfactant approved for food contact in particular from the family of silicone derivatives, as an example of polydimethylsiloxanes, in such a way as to make it hydrophilic and to accelerate the transfer of water.
- the steam generator device can, after the steam production phase, reabsorb the condensates formed during cooling and also the exudates produced by the food product having been treated in the oven. microwave.
- the bag is not waterproof and does not by itself have an absorbent character.
- a superabsorbent such as polyacrylic acid salts should preferably be used as the hydrocolloid, in a quality suitable for food contact.
- the bag has an outer membrane made of a hydrophilic material.
- the sachet can be produced from a paper laminated on a perforated film welded onto itself, the paper being placed outside the sachet.
- the sachet can also be produced in a complex welded on itself constituted by an external face in a perforated non-hydrophilic material and by an internal face in a hydrophilic material in particular constituted by a non-woven.
- This confirmation has the advantage of making it possible to obtain a sachet whose external face is less sensitive to the risks of soiling in contact with food.
- the non-hydrophilic material can be translucent and printed on its internal face in contact with the hydrophilic material.
- a 120 x 80 mm bag made of 30 g / m 2 paper laminated on a perforated polypropylene film heat-sealed on itself containing on the one hand 2 g of super absorbent consisting of sodium polyacrylate and on the other hand 20 g of water can give off approximately 5 liters of vapor per minute of exposure in a microwave oven (750 W) for 5 minutes.
- a sachet of 80 x 80 mm format formed on the one hand of two sheets associated by heat sealing at their periphery, namely a sheet of a material impermeable to water vapor coated with a layer of weldable polypropylene on its internal face and a sheet of nonwoven polypropylene material 75 g / m 2 and containing on the other hand 1.5 g of superabsorbent made of sodium polyacrylate, can thus absorb, in contact with water, by the sheet made of polypropylene, at least 40 g of water in a few seconds.
- This amount of water can be returned by heating, for example in the microwave.
- a sachet of 80 x 80 mm format produced on the one hand in a complex welded on itself constituted by an external face of perforated polyethylene laminated on an internal face of a non-material woven of polypropylene and containing, on the other hand, 1.5 g of super absorbent consisting of sodium polyacrylate, can thus absorb, on contact with hot water, at least 40 g of water in a few tens of seconds.
- This amount of water can be returned by heating, for example in the microwave.
- the retention power of a water vapor generating device according to the invention has been studied.
- bags of 80 x 80 mm format have been produced in a complex welded on itself constituted by an external face made of perforated polyethylene terephthalate (PET) and by an internal face made of a hydrophilic non-woven material made of PET / polyethylene (PE) itself made up of short two-component fibers (PET at the heart and PE at the surface) associated with each other by thermal bonding to form a veil of 35 g per m 2 .
- PET polyethylene terephthalate
- PE polyethylene
- the invention also relates to a packaging for heating or cooking in particular microwaves of foodstuffs, characterized in that it contains foodstuffs as well as a device for generating steam of the aforementioned type.
- This packaging can of course be arbitrary, in particular consisting of a tray of a rigid or semi-rigid material without departing from the scope of the invention.
- such packaging is however constituted by a film, preferably heat shrinkable.
- the film is produced in a plastic material transparent to microwaves.
- the packaging can also incorporate a valve or, for example, a pre-cut, making it possible to prevent it from bursting at too high an overpressure.
- the porosity of the sachet containing the gel can be reduced to a few 10 to 50 ml per minute measured with the Bendtsen porosimeter: in fact, the reduction in the volume of the packaging containing the foodstuff leads to a rapid increase of pressure within it which has the effect of compensating for the internal pressure of the sachet and thus of preventing it from bursting.
- this packaging in accordance with the invention can be adapted to a wide range of applications, in particular for blanching, pre-cooking or cooking fresh fruit or vegetables or even cereals and prepared meals. , and reheating of products kept in negative cold not only by means of a microwave oven, but also by means of a thermal oven ...
- microwave ovens currently available on the market can have two different frequencies.
- the frequency of household microwave ovens is indeed 2450 MHz while the frequency of industrial microwave ovens is 915 MHz. These latter microwave ovens which are used in particular in the food industry for the implementation of defrosting (tempering) processes have a much higher penetration.
- Another advantage of the invention is linked to the fact that it makes it possible to carry out, with conventional household ovens, operations such as the thawing of large blocks of food products which until then could only be carried out with industrial ovens. .
