Bioactive Packages and Package Closures
The invention relates to an active package and/or an active package closure having different formats, made of metal and/or synthetic and/or natural associated or not materials. According to said invention, at least one element and/or component of said packages contains and distributes one or several dietary additives and complements and/or ingredients and technological auxiliaries used for producing foods an cosmetics. The inventive bioactive packages and closures are provided with novel specific functions such as additive and/or technical and/or antimicrobial functions with respect to a packed product. Said bioactive packages and closures confer to packed products sanitary, organoleptic and nutritional characteristics and are used for controllingly preserving the products during packaging, storage, transportation and distribution thereof.
This invention relates to the arrangement, production and industrial applications of new packaging materials represented by devices such as bioactive stoppers, lid seals, seals, caps, lids, plugs and valves designed to close bottles, flasks, jars, boxes, cans, barrels, tanks and other containers used to package and store food and dietary products and cosmetic products.
These new so-called bioactive packages are constituted, alone or in combination, by metal and/or cellulosic and/or synthetic materials, and are characterised by the fact that at least one of their elements and/or constituents incorporates, and/or contains, and/or diffuses biochemical and/or biological substances that confer new functional properties on these packages. A package is generally defined as an assembly of materials designed to receive, contain and protect a good intended to be stored, transported and sold. In particular, a food package must, by virtue of its intrinsic properties, enable optimal preservation of the food contents throughout its lifetime, from production to consumption. It must protect the food from external germs, offer selective gas barrier properties, withstand changes related to temperature or hygrometry of the environment during storage, sale and use by the consumer and comply with regulations.
The packages currently used provide passive functions of receiving, packaging, physical containment and mechanical protection of foods from the environmental factors encountered during the steps of production, storage, transport and sale. The European regulations on packages in contact with food are designed to protect the consumer's health. The European directive 89/109/EC stipulates that the materials and objects intended to come into contact with foods must satisfy the principle of inertial. The materials and objects intended to come into contact with foodstuffs, products and drinks for consumption must not, under the normal or expected conditions of use, transfer constituents to these foodstuffs in an amount that could present a health hazard or lead to an unacceptable change in the composition of the foodstuffs. This directive therefore does not allow the use of active packages that satisfy the following definition according to Wagner (1989): “An active package provides more than simple production. It interacts with the product and in some cases responds to changes in the environment or the product itself”.
A new European regulation has modified the directive 89/109/EC and now takes into account the concept of “active” packages, which authorises the principle of “deliberate transfer or absorption of compounds to or from the food in order to maintain or enhance the conditions of preservation of the product”.
The packaging materials can therefore modify the composition of the foodstuffs only if the modifications comply with the community provisions applicable to foodstuffs, as defined in the directive 89/107/CEE relating to food additives.
Substances such as food additives deliberately incorporated into certain active materials intended to come into contact with foodstuffs so as to be released into the packaged foodstuffs can be allowed. According to Gontard, these active packages can be classified into three main categories:
1) Interactive packages that act in a controlled manner on the food so as to enhance and preserve its quality over the course of the distribution chain. The activity of these packages is intended to control the risks of food deterioration associated with various mechanisms of lipid oxidation, tissue browning, vitamin destruction or microbial contamination. Numerous products are available on the market in the form of oxygen-absorbing bags or carbon dioxide-absorbing bags, produced by Mitsubishi Gas Chemical (Japan), Multiform Dessicant (United States), Bioka (Finland) and Standa (France).
2) Indicator packages that react with the properties of the food and the preservation conditions so as to inform the consumer of said conditions. The devices generally used are Weather/Temperature indicators based on enzymatic- or polymerisation-type reactions. They are produced by various companies: 3M Monitor (Great Britain), Trigon Industries (Great Britain), Lifelines Technology (United States), Pillsbury Co. (United States), Marupfroid (France). Coloured indicators of gas concentration of pH in the package are also sold by Mitsubishi Gas Chemical Co. and Toppan Printing Co. (Japan) and by Trigon Industries (Great Britain).
3) Preparatory packages that make it possible to modify the properties of the food so as to facilitate its consumption. These are essentially self-heating or self-cooling packages proposed by Print Pak Inc. (United States), Baritalia (Italy) and Bréger (France).
In addition, some packaging devices used temporarily during the food production steps are considered to be technological packages. The new bioactive stoppers, caps, lids, lid seals, valves and seals according to the invention differ from the active packages that already exist by virtue of their specific arrangements, their biochemical or biological contents and by their new functional activities. These new packages or package closures are arranged so as to adapt to various types of containers, such as bottles, flasks, boxes, brick cartons, jars, terrines, cans, jugs, barrels, casks, tanks and cisterns, and are characterised by the fact that they comprise at least one element or one constituent capable of producing and/or diffusing at least one non-hydrating substance constituted, in a pure or combined form, by biochemical and/or biological compounds, belonging to the additives and dietary supplements and/or ingredients and processing aids used in the production of foodstuffs and cosmetic products, which substance is in particular a colouring agent, and/or an antioxidant, and/or a preservative, and/or a flavouring agent, and/or a sweetener, and/or an acidulant, and/or an emulsifier, and/or a thickener, and/or a stabiliser, and/or a flavour enhancer, and/or a gas and/or a bioactive ingredient.
The chemical and/or biological compounds can in particular be:
-
- chemical elements (oxygenated free radicals, mineral salts, etc.);
- nitrogenated, chlorinated, iodized, bromated, sulphated, phosphated molecules, etc.;
- biochemical elements (carbohydrates, fats, proteins, metabolites, etc.);
- biological elements (flavourings, vitamins, enzymes, immunoglobulins, etc.);
- microbiological elements (bacteria, yeast and fungi, etc.).
In particular, they can be:
-
- gas (carbon dioxide, sulphur dioxide, nitrogen, etc.);
- salts (sodium, potassium, calcium, magnesium, iron or zinc salts, sodium or potassium phosphates, sodium or potassium thiocyanates, sodium or potassium sulphites, sodium, potassium or magnesium carbonates, sodium or potassium nitrites and nitrates, etc.);
- vitamins (vitamin A and carotenoids, vitamins B1, B2, B5, B6, B8, B9, B12, vitamins C, D, E, K, PP, etc.);
- carbohydrates: lactose, saccharose, fructose, glucose, inulin, fructosaccharides;
- fats: polyunsaturated fatty acids, etc.;
- proteins: lactoferrin, bioactive peptides, lysozyme, etc.;
- enzymes: oxidoreductase, beta-galactosidase, glucose-oxidase, xanthine-oxidase, sulphite-oxidase, peroxidase, catalase, etc.;
- antimicrobial immunoglobulins: antibacterial, antifungal, antiviral, antiparasitic antibodies, etc.;
- microorganisms: lactic bacteria (Lactobacillus, Lactococcus, etc.), yeast (Saccharomyces, etc.), fungi (Penicillium, Streptomyces, etc.).
The bioactive stoppers, caps, lid seals, seals, valves and lids according to the invention are characterised by the fact that they make it possible, when closing the container, to obtain, alone and/or in combination:
-
- the addition and diffusion, immediate and/or delayed, of various compounds and their interaction products contained in the constituents and/or in the elements of the closures to and in the packaged products;
- flavour and/or nutritional enrichment, sanitary protection and prolonged preservation of packaged liquid products (milks, wines, champagnes, ciders, beers, fruit juices, waters, lotions, etc.), semi-liquid products (milk products, vegetable soups, vegetable purees, compotes, jams, creams, sauces, prepared foods, pomades, ointments, etc.) and solid products (fruits and vegetables, powders, grains, etc.).
The type, the mode of assembly and the arrangement of the structural elements, the formulation of the bioactive compounds, the new functional properties and the industrial applications of new packages and package closures (stopper, lid seal, lid, seal, plug, valve, etc.) are the subject of this invention described above, according to five different models provided by way of a non-limiting indication, shown respectively in
These figures are side cross-section views of these various models.
Cap, Lid Seal and Lid with Additive Function According to
According to a first general preferred but not exclusive embodiment of the packaging devices according to the invention, the cap, lid seal or lid model according to
The cap, lid seal and lid models according to
By way of an indicative but non-limiting example, the part 5, composed of low-density and spongy polyethylene, is arranged in an elastic and compressible disk. The part 5 then receives a predetermined filler, in the form of a powder or a solution, of food additives and/or processing aids, pure or combined, represented by preservatives (lactic, acetic, peracetic and tartaric acids, sodium and potassium sulphites, sodium and potassium nitrites, sodium and potassium bicarbonate, hydroxy-8 quinoline, oxygenated water and peroxy salts, ethanol, sodium hypochlorite, nisin and bacteriocins, essential plant oils, etc.), and/or by antioxidants (carbon gas, nitrogen, argon, natural phenolic compounds, etc.) and/or by vitamins (vitamins A, C, E), and/or by sweeteners (polyols, acesulphame, aspartame, cyclamate, thaumatin, neohesperidin, etc.), and/or by flavour enhancers (glutamates, ribonucleotides, ethylmaltol, etc.), and/or by active proteins and peptides (lysozyme, reduced lactoferrin and transferrin, glucose-oxidase, catalase, lacto-peroxidase, glutathion, etc.), and/or by flavourings (eugenol, vanillin, pinene, limonene, geranial). The O-ring seal 6, structured in one or more superimposed layers (6a, 6b, etc.) comprises one or more pores 7 allowing solutions located at 5 to pass toward space 4.
By way of an indicative but non-limiting example, the first layer 6a, made of expanded polyethylene, is filled with a given volume of liquid-phase additives. The layer 6b, joined to layer 6a, is constituted by an aluminium film with a thickness of 0.5 mm, with a barrier effect and impermeable to water and gas (oxygen, nitrogen, carbon gas), which serves as a lid seal after screwing. The placement of the cap on the neck of the container 8 creates a vertical circular pressure on the seal 6 and on the disk 5, which will then release, through the opening 7, most of their respective contents into the packaged product in 8. The residual additives in 5 and 6a then continue their slow diffusion toward the packaged foodstuff in 8, over the course of the storage period. The model according to
According to a first preferred but not exclusive example of the industrial production and application according to the invention, the cap according to
-
- vitamin A (E160a): 400 mg
- vitamin D3: 12.5 mg
- vitamin E (E306): 6.6 g
- linoleic acid: 40 g
- linolenic acid: 50 g
- carnitine: 80 g
- taurine: 3.5 g
- lecithin (E322): 30 g
- water, q.s.f. 1000 ml.
The disk 5 is filled by one millilitre (1 ml) of a mixture of water-soluble vitamins (vitamins B, C, PP, etc.), proteins (lactoferrin, lactoperoxidase, lysozyme, antimicrobial antibodies, etc.), mineral salts and oligo-elements, according to the formulation provided below by way of indication:
-
- vitamin B1: 400 mg
- vitamin B2: 1.5 g
- vitamin B5: 3 g
- vitamin B6: 0.6 g
- vitamin B9: 90 mg
- vitamin B12: 2 g;
- vitamin C (E300-E301-E302): 60 g
- vitamin P: 600 mg
- calcium orthophosphate (E341): 75 g
- magnesium carbonate (E504): 10 g
- zinc: 8 g
- sodium iodide (E010): 150 mg
- bovine ferrin: 0.5 g
- bovine lactoperoxidase: 0.5 g
- ozyme (E1105): 0.5 g
- antiviral lactic immunoglobulins: 50 g
- water: q.s.f. 1000 ml.
The disk 5b and the seal 6a thus filled are inserted on the interior base of the head 1 of the cap. The cap is then attached by its screw thread 2 on the neck 8 of the container. The screwing of the capsule causes the migration and diffusion of the vitamins, salts, fatty acids and proteins contained in 5 and 6a into the milk packaged in 8. The formula milk preparations currently available comprise vitamin-enriched formulations. Some of these vitamins (in particular B vitamins), are heat-sensitive and are destroyed by the heat sterilisation procedures applied to the milk before the packaging thereof. The use of an active cap according to the invention enables the vitamins, and in particular heat-sensitive vitamins, to be added after sterilisation and packaging, thus making it possible to protect the molecular integrity and the biological activity of these vitamins in the formula milk. A characteristic of the active cap according to the invention thus consists of maintaining the nutritional properties of this dietetic milk during its period of storage, transport and distribution.

- a first hollow tubular body 1, made of high-density plastic materials or metal, terminated in its upper portion by a circular edge for contact 2 on the neck of the container 11. The body 1 is closed in its lower portion by a microporous membrane 3 at the cut-off below 0.2 micron and impermeable to water, gases (oxygen, nitrogen, carbon dioxide, etc.) and to molecules with a molecular weight below 100,000 daltons (salts, simple sugars, alcohols and intermediate metabolites, chemical radicals), but impermeable to microbial cells such as bacteria, yeast and mould. The body 1 and the membrane 3 delimit a cavity 4 that acts as a container.
- a second hollow cylindrical body 7 having an upper terminal threading 8 that enables the body 7 to be screwed onto the interior base of the head 5, itself provided with an internal screw threading 6 on the neck 11. The internal cavity 10 of the body 7 is limited in its lower portion by a synthetic microporous membrane 9 at the cut-off below 0.2 micron and permeable to water, gases (oxygen, nitrogen, carbon gas, etc.) and to molecules with a molecular weight below 10,000 daltons (salts, simple sugars, alcohol and intermediate metabolites, oxygenated radicals). The final assembly of the closed bodies 1 and 7 comprises a new stopper having two internal compartments 4 and 10, of which the respective contents are separated from the food distributed by two membranes 3 and 9 with defined porosities.
According to a first indicative but non-exclusive example of the production of the invention according to
-
- the container 4 receives 5 ml of a 5% sodium thiocyanate solution;
- the container 10 receives 10 ml of a sterile 5% glucose solution;
- the membrane 9 is activated by a glucose-oxidase bond (E.C. No. 1.1.3.4);
- the membrane 3 is activated by a lactoperoxidase bond (E.C. No. 1.11.1.7).
By way of a non-limiting indication, the enzyme solutions used for the covalent bonds are prepared in a citrate-phosphate buffer 50 mM with a pH of 7.5, as follows:
-
- solution at 1 mg/ml of fungal glucose-oxidase (E.C. No. 1.1.3.4) at 40 IU/mg—SIGMA grade II—(St. Louis, United States): glucose-oxidase in the presence of oxygen, hydrolyse the glucose into D-gluconolactone (E575), and oxygenated water;
- solution at 0.5 mg of bovine lactoperoxidase (E.C. No. 1.11.1.7) at 40 IU/mg—SIGMA grade II—(St. Louis, United States): lactoperoxidase in the presence of oxygenated water (H2O2) catalyses the oxidation of the thiocyanate into oxythiocyanate OSCN—. The bonding of each type of enzyme is performed by immersion, for 60 minutes at room temperature, for 1 square metre of nylon membrane, of the PALL-Type Immunodyne ABC brand, in a vat containing 500 ml of one of the buffer solutions prepared above. The membrane is then rinsed 3 times with 100 ml of a phosphate buffer at pH 7.5, then saturated by immersion in 100 ml of a 2% bovine casein solution in a phosphate buffer at pH 7.5 for 15 minutes at room temperature. After 3 new rinsing steps with 100 ml of phosphate buffer, the membranes 3 and 9 are drained, then dried at −20° C. in a vacuum and stored at +4° C., in a dehydrated atmosphere, until their final insertion by mechanical bonding on the respective lower end pieces of the bodies 1 and 7 of the plug according to
FIG. 5 . The plug obtained by the final assembly of bodies 1 and 7 is stored in a cold chamber at 4° C. until it is attached to the jug. The stopper of the jug and its storage at room temperature leads to the activation of the enzymatic systems grafted onto the membranes 3 and 9. In the presence of hydrogen peroxide produced by the glucose-oxidase of the two sides of the membrane 9, an oxidation reaction of the thiocyanate ion by the lactoperoxidase occurs in 4 and continues on each side of the membrane 3 with the production and diffusion of acid derivatives oxidised according to the following reactions:
OSCN—+H2O2→O2—SCN—+H2O
Oxythiocyanate+peroxide Superoxythiocyanate
O2SCN—+H2O2→O3—SCN—+H2O
Superoxythiocyanate Trioxythiocyanate
The free radicals produced as well as the oxidised substrates diffuse through the permeable membrane 3 toward the drinking water of the container 11, in which they interact strongly on any microbes that may be present. The lactoperoxidase (LP) system has strong biocidal and biostatic activities with respect to various microorganisms such as bacteria (Listerias, staphylococci, salmonellae, pseudomonae, mycoplasms, etc.), protozoa (Cryptosporidia), viruses (Bacteriophages). The antimicrobial activity of the oxygenated radicals released by the stopper makes it possible to control and/or reduce the microbial contaminants present in the food and leads to prolonged sanitary quality of the packaged water. The natural LP antimicrobial system, integrated in a packaging device for fragile products, constitutes a new industrial application, which is the subject of the invention. The characteristic properties of the packaging device according to
