Description

  The invention also relates to plant fiber products and methods for producing such products. In particular, the present invention relates to controlling the release rate of substances such as caffeine, nicotine and other additives added to the product.

  Numerous different types intended to give taste to the user when used orally or through delivery of substances such as nicotine and caffeine via the mucous membrane of the mouth There are plant fiber products. Such products typically include tobacco, such as snuff (dry or moist) and chewing tobacco. However, many tobacco-free alternatives whose products are based on other plant fibers are eg SE 529 886 (buckwheat and corn fiber), US 2007/0000506 (coffee and tea) and WO 2009/010884 (tea and citrus) Fiber).

  For example, from WO 2009/010884 it is known to add functional or active substances such as caffeine, mint, cinnamon, antioxidants and vitamins to such oral products.

  Using this type of product, the additive tends to dissolve relatively quickly and is available through the mucosa for absorption in the user's bloodstream. Such a rapid delivery rate may be advantageous in certain situations, but sometimes there is a slower delivery where the additive is delivered to the user at a slower delivery rate, however, for a longer period, sometimes within an hour. desirable.

  To be able to prolong and control the delivery rate, it is possible in WO 2009/010884 to contain taste substances and other substances and, for example, to be crushed by the user's teeth, especially when desired It has been proposed to use small, solid capsules that are possible. However, it is not disclosed how these capsules can be specifically formulated or produced.

  Thus, there remains a need for a solution to control the rate of additive release.

SE 529 886 US 2007/0000506 WO 2009/010884

  It is an object of the present invention to provide a vegetable fiber product for oral use that allows a better control of the additive release rate than is achieved in existing products. This object is achieved by the product and method according to claims 1 and 12. The dependent claims disclose advantageous embodiments, developments and variants of the invention.

  The present invention relates to a plant fiber product for oral use, said product comprising at least one additive and at least a mixture of plant fibers intended to be released from the product when said product is used .

  A product according to the present invention comprises an alginate composition comprising at least water, alginate and additives dispersed in the product, said composition comprising at least one of the additives unless the alginate matrix is damaged. It contains an alginate matrix that retains the bulk and because the alginate matrix is formed, it can disintegrate and / or dissolve in the chemical and physical environment present in the user's mouth.

  The advantageous effect of such a product is that the alginate matrix gradually disintegrates and / or dissolves when the product is used, which means that the additive is gradually released in the mouth. To do. In such a manner, the release of the active substance is regulated so that the release of the active substance occurs over a specific period. When the additive is an active substance intended to be absorbed by the user, such as caffeine or nicotine, the preferred delivery of the active substance from the product through the mucosa to the user's bloodstream is where the matrix dissolves / As long as it continues to collapse, it can be achieved. When the additive consists of a gustatory substance, the gustatory substance is delivered over a long period of time to the user's mouth, which means that the taste can be maintained for a longer period of time. For example, by changing the relative amount in the type (s) of the alginate or its / its composition, the delivery rate of the additive can be modified to change over time and even manufactured The alginate matrix can then be formulated or prepared.

  A further advantageous effect of the product according to the invention is that the alginate composition / alginate matrix is present as a protective coating for the additive (s) until the release of the bound additive. This means, for example, that oxidation-sensitive substances are protected from contact with oxidants. Such oxidizing agents are derived, for example, from plant fibers or can be added during the latter (pre) treatment. A protective coating means that it is also possible to maintain an appropriate pH in the local environment of the additive. The pH can also be influenced by substances derived from plant fibers or their treatment. Antioxidants and / or pH buffer substances can be included in the alginate composition according to the invention, for example, to provide further protection of the active substance present in the protective coating.

  Alginate, a salt of alginic acid, is a well-known substance that is commercially available. It is used, for example, as a thickener and gelling agent in the manufacture of foodstuffs and similar products, such as plant fiber products of the type relevant to this description.

  The phrase `` oral use '' refers to a product that is placed somewhere in the user's oral cavity, e.g. under the lips, in the same manner that moist snuff products are normally used in normal use. means.

  The phrase “additive intended to be released from the product when it is used” refers to any substance or agent added to the product in addition to all substances that may be derived from plant fibers. means. Suitable plant fibers for products according to the present invention may include substances such as thein, caffeine or nicotine that are also released when the product is used. The phrase is also intended to mean a substance that is specifically intended to be released from a product when used for the purpose of feeling a taste to be swallowed or absorbed by the user through the mucous membrane of the mouth. Understood.

  The phrase “alginate matrix” refers to the network that alginate forms when dissolved in water. The alginate matrix is in the form of a solution / mixture, and its viscosity and rapid dissolution generally vary with, for example, the type of alginate, the alginate / water ratio, temperature, and the like.

  In a preferred embodiment of the invention, the product is adapted to deliver a substance to the user via the mucous membrane in the user's mouth, in addition, the at least one additive comprises an active substance, for example caffeine. And can be absorbed through the mucosa in the mouth when the product is used.

  The phrase “active substances that can be absorbed through the mucosa in the mouth” first means those substances that enable delivery to the user's bloodstream via the oral mucosa. Next, the term “active substance” has such a substance that has a significant effect on the user after being absorbed, such as a substance having a stimulating action on the central nervous system, a vitality effect, an antipyretic action or an analgesic action. It is understood to mean substances or substances useful for the body, for example vitamins, antioxidants and minerals.

  In a preferred embodiment of the present invention, the at least one active substance comprises one or more substances belonging to any of the following categories: API (active drug substance), food additive, natural drug or Naturally occurring substances that can have an effect on humans. Examples of such substances are caffeine, nicotine, vitamin B12, vitamin C, vitamin E, bioperin, Q10, selenium, glutathione, lipoic acid, folic acid, ginseng, pollen extract, Antioxidants, minerals, paracetamol, acetylsalicylic acid, Rhodiola rosea (Russian root) and Iwabenkei.

  In another preferred embodiment of the invention, the at least one additive is a taste substance.

  In another preferred embodiment of the invention, the alginate comprises a monovalent cationic alginic acid salt. Preferably, the alginate is soluble in cold water. Such alginate allows the formation of an alginate matrix with appropriate stability and also allows a simple production process.

  In another preferred embodiment of the invention, the alginate comprises at least two different types of alginate having different dissolution or degradation properties. Typically, different types of alginate have different viscosities in the dissolved state. Such alginate combinations can be used to form an alginate matrix that exhibits a characteristic release curve, for example, while the less viscous alginate allows for a relatively high initial release. The more viscous alginate makes it possible to continue the release more or less continuously for a longer period of time. Thus, in this case, the alginate matrix consists of two or more types of alginate.

  In another preferred embodiment of the invention, the plant fiber is based on one or more of the following plants: tea, coffee, tobacco, cocoa, maize, herbs, yerba mate and cellulose. The tea fibers preferably account for a significant proportion. Furthermore, preferably the plant fiber exhibits a particle size distribution mainly in the range of 0.1 to 0.9 mm, for example after grinding and sieving, preferably the plant fiber is steamed. Such treatment of plant fibers produces advantageous products that can be baked, for example.

  The present invention also relates to a method for producing a plant fiber product for oral use, comprising the following steps: mixing plant fiber and other ingredients contained in the product. The method according to the invention is also characterized in that it comprises the following steps: (i) at least water, alginate, and at least one kind intended to be released from said product when it is used Mixing an alginate composition comprising an additive, wherein the composition at least partially comprises an alginate matrix that retains at least a majority of the additive unless the alginate matrix is damaged. Forming and alginate matrix so that it can disintegrate and / or dissolve in the chemical and physical environment present in the user's mouth, and (ii) plant fibers Mixing with the alginate composition.

Preferred Embodiments Products according to the present invention typically comprise one or more additives in the form of water, treated plant fibers, and taste substances, and one or more added active substances, for example cafes. Including. Apart from the added active substance, the plant may of course contain an active substance derived from plant fibers. The plant may contain a colorant.

  Plant fibers usually constitute the main component of the product and, among other things, give the product its structure. It is well known that plant fibers can be treated in many different ways for the types of products related to this specification.

  In the preferred examples described herein, the plant fibers consist of tea fibers. These are suitably (pre) treated, similar to the manner in which snuff is produced. The main features of this process may be described by the following method steps:

A) Drying, grinding and screening process. A suitable particle size and size distribution for tea fibers is mainly 0.1-0.9 mm, with an average value of about 0.5 mm.
B) Water and salt addition process.
C) Heating, injection of steam, and mixing.
D) Cooling process.
E) For example, the process of adding sodium carbonate, preservatives, taste substances, humectants and binders.

  Tea fibers treated in such a manner provide a bakeable product that can be compressed into snuff-like parts in a loose form.

  Preferably, step E is followed by an intermediate storage stage and a stage where a finished product is formed. This final stage involves the proper packaging of the product in a box, either in the form of pieces or in the form of a serving sachet, such as a pinch of snuff. Another suitable form of the final product is suitably compressed into a somewhat softened troche / tablet so that it can be more easily consumed in use. The finished product may have a film-like form.

  Suitably, the finished plant fiber product has a moisture content of about 40-60%, preferably 45-48%, relative to the product in a serving sachet and is a bakable disjointed product ( has a moisture content of 50-54% for loose product).

  Examples of formulations relating to preferred embodiments of products according to the invention and examples of preferred methods relating to their production are described below.

  The alginate composition produced according to steps 1-2 is then suitably added to step B and / or step E in the process of treating plant fibers. The heat sensitive material is suitably added to step E.

Formulation:
10 parts by weight (pretreated) tea fiber
10 parts by weight of water
2 parts by weight Protanal® LFR 5/60 (FMC BioPolymer) alginate
0.1-0.5 parts by weight glycerol about 0.3 parts by weight caffeine about 0.5 parts by weight vitamin B12
Bergamot (in an amount according to the desired taste intensity)

  In another preferred embodiment of the invention, except caffeine, vitamin B12 and bergamot, instead about 0.01 parts by weight of nicotine and licorice (in an amount according to the desired taste intensity) are included. In another preferred embodiment of the invention, 0.5 parts by weight of acetylsalicylic acid and peppermint (in an amount according to the desired taste intensity) are included instead. It is also possible to combine the various embodiments, remove specific tastants or active substances, and / or create variants with other active substances and gustatory substances.

  The relative amount of material in the product can of course vary. For example, the amount of active additive can be adjusted to contain an appropriate portion amount according to the total weight of the portion size for the actual product. A typical vegetable fiber product has a total weight of about 1-2 g. In general, suitable amounts of any additive are as follows: caffeine about 50 mg; vitamin B12 about 10 to 100 mg; nicotine about 1 to 3 mg; and acetylsalicylic acid about 100 mg.

  The total amount of additive should not normally exceed about 75% of the weight of the alginate and preferably should not exceed 50% of the weight of the alginate so that the alginate matrix can be present in a stable manner. This may mean, for example, that depending on the type of alginate and the type of substance, the active substance should be added in a smaller amount than that corresponding to the generally appropriate amount described above.

Method:
1. Preparation of an aqueous solution containing water and glycerol, active substance and taste substance (according to the above formulation).
2. Add alginate to aqueous solution. Mixing to obtain a homogeneous (homogenously mixed) aqueous / alginate composition.
3. Addition of alginate composition to pretreated tea fiber.
4. Mixing to get a well mixed vegetable fiber product.

  In step 1, the purpose is to dissolve the ingredients. PH adjustments may be necessary so that certain substances such as nicotine and paracetamol can be completely dissolved. PH adjustment may also be important to facilitate absorption of certain active substances by the mucosa. In particular, glycerol has the property of increasing solubility, but also has the property of improving the consistency of the finished product.

  In step 2, it is important to add the alginate relatively slowly and to stir the mixture fairly vigorously so that the alginate can be properly dissolved. It may be necessary to stir for up to 30-60 minutes. It is possible to promote dissolution of alginate by employing a temperature increase up to about 50 ° C., provided that the active substance added is not temperature sensitive. In general, it is best to operate at room temperature.

  Alginate is generally composed of different types and cations that offset different lengths and types of polysaccharide molecules and the negative groups of polysaccharide molecules. In the above example, Protanal 5/60, which is a low viscosity sodium alginate soluble in cold water, is used. The expression soluble in cold water means that the alginate is completely dissolved in water at room temperature.

  When the alginate dissolves in water, a matrix is formed, that is, a network is formed in which the alginate molecules bind not only to the water molecules but also to each other, thereby increasing the viscosity of the solution. Substances dissolved in water, for example active substances added, are retained more strongly, inter alia because they prevent electrostatic forces and steric hindrance from leaving the matrix.

  The viscosity produced when the alginate dissolves is mainly due to the type (s) of the alginate (eg, the average molecular length and proportion of so-called G (guluronic acid) and M (mannuronic acid) blocks), alginate Depending on the concentration and temperature.

  The viscosity of the alginate composition is a good measure of the ability of the alginate matrix to hold the binding material strong: the higher the viscosity, the more usually the material binds more tightly.

  The composition formed when the alginate dissolves in water is said to be in the form of a solution, but because the viscosity may be relatively high, the composition does not necessarily have these properties normally associated with the solution, Does not show the ability to pour like a liquid, for example

  After step 2 above, under normal conditions, i.e. before the plant fiber product is used, for example when no further substances are added which can even disintegrate or dissolve the matrix, the viscosity of the solution / composition is The substance is high enough to bind strongly in the alginate matrix (and thereby high enough to bind strongly in the product when the composition is dispersed in the vegetable fiber product). At the same time, the viscosity in such an example is sufficiently low to allow the alginate composition to be delivered during the manufacturing process and to allow simple and effective mixing with plant fibers. Furthermore, the viscosity of the composition is sufficiently low to allow the binding material to be released from the matrix at an appropriate rate when the product is used (see below). At higher viscosities, the solution / matrix will have to be mechanically disjointed so that it can be completely dispersed during mixing with the plant fibers. A viscosity that is too high can prevent or significantly delay the release of certain binding substances when the product is used.

  The active substance in step 1 is added to the aqueous solution and dispersed, and this solution (even in a more viscous form) is mixed with the plant fiber in a later step and thereby dispersed in the product Thus, the active substances can be homogeneously dispersed in the final plant fiber product despite the fact that they account for a relatively very small proportion. Achieving good dispersion of small amounts of active substance in the dry form is significantly more difficult.

  The alginate composition is combined with tea fibers in step 3 such that a fully mixed product mixture is formed in step 4. A composition comprising an alginate matrix and a substance bound therein is thereby in the form of a layer of fibers and / or in the form of smaller isolated units (“droplets”) Disperse in plant fiber products.

  The bound material is strongly retained in the alginate matrix unless the plant fiber product is exposed to any particular action, such as evaporation, temperature rise, or the addition of large amounts of water or other liquids. The bound material may be strongly retained in the matrix, optionally for up to 1 to 3 years, provided that the product is stored in an appropriate manner, for example, hermetically, stored at low temperatures and protected from sunlight.

  For example, when chewing tobacco is used and the product is placed in the mouth under the lip by the user, the chemical and physical environment present in the user's mouth will cause the alginate matrix to collapse and / or dissolve. The conditions are completely different in this case. In particular, this is due to the presence of saliva, where the water content of saliva acts to increase the amount of solvent that dissolves the matrix, and moreover, the alginate matrix polysaccharide is smaller and more easily dissolved. By including an amylase that breaks down into components. Furthermore, the relatively high temperature in the mouth contributes to the disintegration and dissolution of the matrix, for example compared to a cold storage location.

  In this way, the matrix gradually dissolves and / or disintegrates, causing the release of the already bound substance over time. Active substances that are no longer bound in the matrix often come into contact with the mucous membrane in the mouth via saliva and migrate in this way into the user's bloodstream. In this way, the active substance is also absorbed over a period of time. With respect to gustatory substances released from the matrix, they migrate into the mouth and create a taste. In this way, the product tastes for a longer period of time than if no tastant was bound in the matrix.

  By adapting the alginate composition, i.e., inter alia, the alginate matrix, the overall release time can be adapted and the release curve (s) of the additive substance (s) are given in a suitable form. An important parameter is viscosity, which, for example, changes the amount of alginate, changes the type of alginate, and changes the relative amount of different alginate in relation to the amount of water in the composition. Can be adapted. The alginate composition may be adapted after it has been added and mixed with the plant fiber, for example by subjecting the plant fiber product to evaporation. Evaporation reduces the water content, which affects, for example, the viscosity of the alginate matrix.

  The treated plant fiber may contain substances that affect the alginate composition. For example, certain substances may have a special effect on the alginate matrix. Further, for example, the pH and moisture content may vary in the plant fiber mixture depending on the type of fiber and the treatment process, which can affect the alginate composition. The alginate composition is suitably adapted for the particular situation.

  Since larger products, for example, lead to longer diffusion times, the release time of strongly held substances is also dependent inter alia on the size of the product placed in the mouth. In accordance with the described embodiments of the present invention, a total release time of about 30-60 minutes is obtained for a typical size of a typical user and product, i.e. roughly the same as a regular snuff. In other words, the product delivers the active substance and / or taste substance to the user for about 30-60 minutes from when the product is placed in the mouth.

  It goes without saying that the plant fibers according to the invention can naturally comprise further amounts of water, alginate and substances in addition to those contained in the specific alginate composition. Alginate is particularly suitable for inclusion in plant fiber products, since it has a therapeutic effect on the mucous membrane and further contributes positively to the baking ability of the product This is described herein. Furthermore, alginate is suitable to give the product a softer appearance in the form of a troche / tablet. Alginate having a therapeutic effect promotes baking ability and / or acts as a softening agent that can be derived from an alginate composition and / or derived from further added alginate.

  Examples of active substances suitable for addition to a product by binding to an alginate matrix as described above preferably belong to one of the following categories: effective for humans APIs (active pharmaceutical ingredients), food additives, natural drugs and naturally occurring substances that can (and also have a placebo effect). Specific examples of such substances include caffeine, nicotine, vitamin B12, vitamin C, vitamin E, bioperine, Q10, selenium, glutathione, lipoic acid, folic acid, ginseng, pollen extract, antioxidants, minerals , Paracetamol, acetylsalicylic acid, Rhodiola rosea (Russian root) and Iwabenkei. Thus, active substances are those substances that have a significant (perceivable) effect on the user, for example substances that act as central nervous stimulants, substances that have a nourishing effect, antipyretics or analgesics, or It is understood to mean substances useful for the body, for example vitamins, antioxidants and minerals.

  As mentioned above, examples of gustatory substances suitable for addition to products via binding to an alginate matrix are licorice, mint, bergamot, aniseed, citrus compounds, elder, and the like.

  With respect to the viscosity of alginate compositions, it is generally said that as the viscosity increases, the ability to form hard / poorly soluble compounds / mixtures also increases. Lower viscosity means faster wetting and faster dissolution of the mixture. Since binding capacity and water retention capacity are functions of viscosity, more liquid is required to dissolve the higher viscosity mixture. The proportion of G block and M block also affects the dissolution / degradation time. A higher proportion of G block accelerates dissolution and adhesion to the mucosa. Longer polysaccharides produce higher viscosity and less soluble mixtures. They also require more saliva for their dissolution. Shorter polysaccharides produce lower viscosities and dissolve more easily with less saliva.

  The polysaccharide is in the form of a salt with a positive charge. In addition, there are partial charges and functional groups / sites along the polysaccharide that allow substances to bind to these functional sites via ionic bonds, van der Waals forces and dipolar bonds. Furthermore, a purely mechanical bond between the polysaccharides means that the substance is strongly retained in the matrix.

  The mechanical function also contributes to the viscosity of the alginate composition. Longer steric molecules bind more easily to each other and are strongly retained by mechanical and chemical bonds with other solvents and incorporated materials.

  The invention is not limited to the embodiments described above but may vary within the scope of the invention as defined by the following claims. As an example, the plant fiber used does not necessarily have to be based on tea. In addition to mixing different types of tea, it is also possible to base plant fibers on eg herbs, cocoa, coffee, Yerba mate, maize, cellulose and liquorice root . Tobacco can also be used. It is also possible to use a mixture of plant fibers from two or more different plants. The method described for tea fibers is also suitable for other plant fibers.

  As a further feature of the present invention, the active substance and / or taste substance can be added to the plant fiber product in a conventional manner, in other words, without being bound to any alginate matrix.

  Alginates suitable for the present invention are generally monovalent cationic alginate that is soluble in cold water and has a low viscosity. An alternative to the alginate LFR 5/60 exemplified above is Protanal® LF 10/60 (FMC BioPolymer), which is also sodium alginate but has a higher viscosity. Higher viscosities require longer dissolution times and also result in longer total release times of about 1 to 1.5 hours. In order to dissolve LF 10/60, usually a larger amount of water per part by weight of alginate is required than that used in the formulation.

  Other mixtures of alginate with other dissolution or degradation characteristics can be utilized to modify the additive release curve. For example, 2 parts by weight of LFR 5/60 can be mixed with 1 part by weight of LF 10/60, and this alginate mixture can be incorporated into the alginate composition. For these proportions in the alginate matrix, a release profile is obtained that shows a relatively quick initial release, which is mainly due to the dissolution of LFR 5/60, which dissolves more readily, and over time. Changes to a more stable release, mainly due to the slower dissolution of LF 10/60. By changing the ratio of LFR 5/60 and LF 10/60, it is possible to further improve the release profile or release curve. Of course, one or more other alginate can be mixed to further adapt dissolution / release. Of course, in general, the release profile and release time are highly dependent on the production of the user's saliva, how the product is retained in the mouth, and what additives are involved.

  Divalent cations, such as Ca alginate, generally form irreversible solutions / matrices / gels, which typically release binding substances significantly more slowly. Certain substances can be released by diffusion fast enough. Also, the divalent cation alginate can be used in products according to the present invention in at least a relatively small amount in combination with one or more monovalent cation alginate.

  In a further method step, it is also possible to stabilize the alginate composition before adding it to the plant fiber by heating the alginate composition.

  Note, for example, that absorption into the blood through the mucous membrane of the mouth occurs more quickly and is significantly more effective, at least for API, compared to absorption through the stomach / intestine / liver. Should. This means that in the case of absorption by the mucosa, the API dose can be reduced to a maximum of 80% depending on the liver metabolism. Such smaller doses result in fewer side effects.
