Definitions
- the present invention relates generally to the manufacture of cork-based stoppers, and more particularly to a " method for treating a cork-based product which can be used for making stoppers.
- the cork from which the corks are made is a plant tissue produced by the suberophellodermic base of the cork oak.
- Cork consists essentially of about 45% suberin, which is the main constituent of alveolar cells, about 27% of lignin with a fibrous structure, found in inclusion in channels or on the surface of the bark, about 12% cellulose, and about 17% other miscellaneous products such as ceroids, tannins, minerals, and water.
- Cork is a good material for capping and storing still or sparkling drinks, in particular, wines or other bottled alcohols, because it is a compressible and sufficiently elastic material, waterproof and hydrophobic.
- Cork contains about 5% moisture but hydrates slowly.
- cork is a natural material which has more or less significant defects.
- cork tastes substances or their precursors which can give corked wines or alcohols, during aging, unpleasant tastes called "cork tastes”.
- the main substances identified are: - 2,4,6-Trichloroanisole (TCA), - 2,5-dimethyl pyrazine,
- the traditional cork treatment process for the production of corks includes a boiling operation carried out on cork boards or cork bark dried for approximately 2 years. This operation consists of immersing said planks or bark of cork for approximately 1 hour 30 minutes in a boiling water bath at a temperature of the order of 100 ° C.
- This boiling operation is followed by a standing time which varies from 48 hours to about three weeks to stabilize in particular the excessive humidity of the treated product.
- cork planks or barks thus treated are then used in the cork manufacturing chain.
- the resting step is a critical step during which the cork can be contaminated with bacteria or mold, which can be at the origin of the "taste plug ".
- the plug manufacturers have made of agglomerated corks made of medium or low quality cork particles and a binder or glue which ensures the cohesion of the corks.
- Such a stopper consists mainly of a powder of woody vegetable material originating in particular from cork, expanded microspheres of plastic material and food glue.
- agglomerated corks although they are economical to manufacture, have physico-chemical and mechanical characteristics much inferior to those of natural cork stoppers and cannot therefore be used for the conservation of wines or alcohols intended to age in bottles .
- agglomerated corks does not make it possible to eliminate the appearance of cork tastes in wines or alcohols bottled and corked with such corks.
- the present invention provides a new method for treating cork-based products which can be used for making corks, which in particular makes it possible to eliminate the risks of the appearance of cork tastes in skincare or alcohol bottled. More particularly, the method according to the invention comprises the following steps: a) the said product is introduced into a sealed container, b) the said product is subjected to the action of water vapor under a pressure of between 2 .10 5 and 30.10 5 Pa for a period of between approximately 5 seconds and 5 minutes, c) an expansion is carried out to bring the interior of the container to atmospheric pressure, d) the treated product is recovered.
- the cork-based products used for this process can be boards or pieces of cork, intermediate products such as pellets, casing waste, sorting waste or even finished products such as stoppers and scrap.
- the process according to the invention applies to all cork-based products which can be used in the composition of a stopper.
- the process according to the invention makes it possible, in a very short time, to effectively flavor the cork-based product, in particular by modifying in said product the content of the substances listed above which cause alterations to the wine or their precursors.
- such a process advantageously makes it possible to sterilize the cork-based product, by destroying the microorganisms contained in this product, which can be precursors of the abovementioned substances giving the wines unacceptable flavors.
- the treatment method according to the invention makes it possible to obtain cork in different forms.
- step c) a slow and progressive expansion is carried out.
- This embodiment is used in particular for treating a cork-based product already in the form of powder or small granules.
- step c) rapid, brutal expansion is carried out.
- Such a binder is a food binder of the polyurethane binder type.
- This variant of the process can also be used to obtain from planks or large pieces of cork, treated granules, subsequently used in the manufacture of agglomerated cork stoppers using a binder such as a food adhesive.
- step b) dry water vapor or wet water vapor.
- the pressure of the water vapor used in step b) corresponds to a temperature inside the container of between approximately 120 ° C. and 230 ° C.
- the product contained in the container is penetrated by the water vapor introduced into the latter, so that its temperature increases to a temperature between 120 ° C and 230 ° C, and that softens it.
- step b) steam under pressure is introduced into the container. This can advantageously be achieved by creating inside the container, a flow of water vapor.
- step b) has a duration of between 30 seconds and one minute.
- step b) the container containing the product and water is heated, for a treatment with wet steam.
- the invention also provides a stopper for closing bottles of still or sparkling alcoholic drinks or carbonated drinks, which comprises a cork-based product treated using the above method.
- cork granules free from defects were contaminated with Trichloroanisole and were treated using the process according to the invention.
- Contaminated granules have a characteristic odor of corky taste (moldy, earthy). These granules were subjected to the action of water vapor under a pressure equal to 20.10 5 Pa for one minute followed by a sudden expansion of the pressure.
- a cork powder was thus recovered directly at the outlet of the container.
- the cork powder treated according to the process according to the invention was macerated (10 g / l) in a hydroalcoholic solution at 20% by volume for 48 hours. Once filtered, the solutions obtained were offered to tasters.
- the tasters have two references: -a control glass without TCA and a control glass polluted with TCA.
- Table 1 is a summary of the average scores obtained out of 10.
- non cork A2 non cork B1: cork B2: contaminated, uncontaminated, contaminated, uncontaminated cork, treated treated treated treated
- sample B1 become sample B2
- the tasters no longer perceive the characteristic smell of TCA.
- the cork powder treated according to the process according to the invention is introduced into alcohol at 96% by volume at a concentration of 5 g / 11 ml.
- the detection threshold is 5 picogram / microliter.
- the chemical analyzes carried out on the treated cork powder confirm the above-mentioned sensory analysis results.
