JO These additives are also used in conjunction with waterproofing agents, e.g. B. glyoxal and dialdehyde starch are used. These additives, especially the commonly used binders or "spreaders", waterproofing agents, etc., are limited in quantity to the necessary minimum because they are less desirable than tobacco leaves in terms of taste and aroma and other smoking properties. Furthermore, tobacco products have been hitherto in the various forms, e.g. B. cigarettes, cigars and fine-cut tobacco, all made using naturally grown tobacco as a smoking material and processed in various ways Market for tobacco products with a mild taste. In accordance with this need, the development of tobacco substitutes which can replace the natural tobacco leaves in whole or in part is making rapid progress.

Cellulose derivatives, ζ Β, are used as smoking materials to replace tobacco (fuel). Carboxymethyl cellulose, Carboxyethyl cellulose, hydroxyethyl cellulose, carboxymethylhydroxyethyl cellulose, methyl cellulose, Ethyl cellulose and hydroxypropyl cellulose, starch derivatives, z. B. starch, carboxymethyl starch and carboxyethyl starch, and other materials are known. Certain Properties of these fuels are still in need of improvement from the standpoint of their taste when smoking and their burning behavior. It is therefore used by manufacturers of tobacco substitutes expects that they will make a fuel available as a substitute for the known fuel.

In-depth investigations by the applicant with the aim of determining fragrance, aroma and taste, physical Improving properties, processability and other properties of tobacco products have shown that a thermally gellable polysaccharide of the /3-1.3-glucan type (hereinafter referred to as polysaccharide), d. H. a thermally yellow;: res polysaccharide, which consists predominantly of / M, 3-glycoside units, has excellent binding properties and the ability to reduce the smoking properties, e.g. B. fragrance, aroma, Taste and irritation of tobacco products as well as the physical properties of smoking materials, z. B. their strength. Tensile strength, elongation, maturity, wet or water resistance, flexibility and To improve the yield and a desired burning behavior with the formation of less tar and less contains harmful substances. It was also found that the polysaccharide as a tobacco substitute folic without Binder and wetting and waterproofing agent can be used. These are the objectives of the invention Findings.

As the polysaccharides used for the purpose of the invention are those of vegetable Origin, polysaccharides formed by microorganisms, etc. are known. All of these polysaccharides can be used with Advantageously used for the purposes of the invention, however, are those formed by microorganisms Polysaccharides very readily available. Examples are those of microorganisms of the genus Alcaligenes and the polysaccharide formed by microorganisms of the genus Agrobaccharium. Especially too Mention should be made of the polysaccharide from Alcaligetics faecalis var.myxogenci 10C3K (Agricultural Biological Chemist-y 30f 19661, 1% ff by Il a racla

et al., hereinafter referred to as Polysaccharide A), the polysaccharide obtained from the mutant NTK-u (1FO-I3140, ATCC 21680) from Alcaligenes faecalis var. Myxogenes 10C3 «. is formed (US-PS 37 54 925 and 38 22 250) (hereinafter referred to as Polysaccharide B), the polysaccharide produced by Agrobacterium radiobacter (I FO-13127, ATCC 6466) or his Mutant U-19 (IFO-13126, ATCC 21679) is formed (U.S. Patents 3,754,925 and 3,822,250) (hereinafter referred to as Polysaccharide C) and Pachyman Main component of Poria cocos (Agr. Biol. Chem-, VoI 32, No. 10 [1968], 1261) and the like.

The polysaccharide can be used as a purified or raw preparation. Suitable as a raw preparation the culture medium of a microorganism that is able to produce the polysaccharide, or a material that by removing the cells of the microorganism from the culture medium, or any other raw materials used in the various stages of purification of the aforementioned materials can be obtained.

The properties and advantages of polysaccharide as an additive for smoking materials are discussed below received in detail.

The polysaccharide has an advantage that the smoking properties are improved. By adding the Polysaccharide to common smoking material not only improves its smoking properties, but also the Use of the polysaccharide in place of the usual additive or additives results significantly improved «: smoking properties. The reason for this is believed to be that the polysaccharide is included the pyrolysis and combustion less unpleasant odor and pyrolysates with less; Irritant effect and also the aforesaid improved physical properties are evident are responsible to a certain extent for improving the smoking properties.

Another advantage is that there is a reduction in nicotine and tar levels will. These results are inevitably achieved, in part by the fact that the threadly cut Tobacco, in which the polysaccharide has been incorporated, increased bulk due to the simultaneous Using a filler such as sodium carbonate and ammonium carbonate with the polysaccharide is further increased, and has other improved physical properties, so that such Assuming the same capacity as the common cut tobacco in the product Strength is superior, with the result that when a tobacco product is mine. given firmness is the goal, the polysaccharide helps reduce the amount of thread-cut tobacco required and in part because the polysaccharide contains no nicotine and a much smaller amount of tars forms than the cut tobacco.

The polysaccharide is also an excellent binder and gives better binding power and better smoking properties than the previously known binders such as galactomannagum, locust bean gum, Carboxymethyl cellulose, carboxymethyl starch. Sodium alginate and sodium pectinate.

At the moment, carboxymethyl cellulose is generally used, but this additive is inexpedient, since he is the tobacco foil under the humid conditions in the manufacturing process Klcbrigkcit gives as well as an unpleasant odor when

Has burning.

In contrast, the polysaccharide has procedural the advantage that with it a water-insoluble and non-sticky tobacco sheet is formed. As a result, the manufacturing process and the yield of tobacco product are made easier is increased. In addition, when using the polysaccharide, the existing tobacco processing machines can be used without modification. When using the above known ?! As a binder, it is necessary, for example, to use a waterproofing agent, e.g. B. glyoxal or Dialdehyde starch, to be used in combination with the binder. However, since the polysaccharide is both Has excellent binding properties as well as excellent wet strength, is waterproof and wet-strength making means not absolutely necessary. The polysaccharide can be used together with a suitable Amount of another known binder can be used, and in this case, too, no wet strength has to be used and moisture proofing agent can be used. When the surface of the Cigar wrappers and paper used in the manufacture of cigarettes and the like the polysaccharide is treated, the surface finish improved in terms of smoothness and other properties, and because of the achieved increased wet strength; ind moisture resistance becomes the loss of fragrance. Smell, aroma and moisture from the smoking material used as the filling and accordingly prevents discoloration and staining of the sheet and paper tube, so that general deteriorations in the quality of the tobacco product are eliminated. Furthermore, the excessive wetting of the tobacco product with saliva and the resulting unpleasantness Improved sensation when touching the smoker's lips.

The method and timing of adding the polysaccharide to the smoke material! sir! practically unlimited.

As for the way of using the polysaccharide, the powdery polysaccharide can be used as such are used or previously swollen or made easily swellable. The latter condition is for example by a dispersion of the polysaccharide in water, aqueous alcohol, aqueous polyol, aqueous ammonia and the like and a gelation product of the polysaccharide.

The dispersion preferably has a concentration in the range from about 0.5 to. 10% by weight The gel formation product can be obtained, for example, by preparing a dispersion containing 0.5 to 10 wt Temperature of about 65 to 200 ⁰ C, preferably about 70 to 150 ⁰ C, heated and allowed to stand at this temperature. Another method is to add the polysaccharide to an aqueous 0.1 N to 3 N alkali solution, e.g. B. to a sodium hydroxide, potassium hydroxide or sodium carbonate solution, and then neutralize the dispersion or add calcium hydroxide or calcium carbonate, for example, and then neutralize.

In this process, a porous, clear Product can be obtained by adding your polysaccharide a propellant or mandrel forming agent. /. B.

Sodium bicarbonate and ammonium carbonate, added.

The above-mentioned gel formation product can be converted into sheets or others in a conventional manner any shape can be processed. The sheet-like gel formation product can be in any suitable manner Sizes can be cut threadly, and this cut material can also be various flavoring and Flavoring agents are added, or the polysaccharide to which the flavoring agents were previously added may be gelled.

Can be used as flavourants and flavoring agents all substances commonly used as tobacco additives in question, d. H. Extracts such as tobacco extract and Licorice extract, menthol, esters of organic acids, amino acids, proteins, essential oils, fruit extracts like peach, walnut and cherry etc.

The amount of flavoring and flavoring agents to be used depends on factors such as the intended use, desired taste, etc., but it is preferably about 0.1-10% based on the weight of the product of gel formation.

The gel formation product and the polysaccharide can also contain an appropriate amount of catalysts that promote glowing, materials that promote cohesion improve the ashes, etc. are added. As catalysts that promote the glow and that To ensure »fire maintenance«, alkali compounds are preferred.

Ammonium, alkali or alkaline earth salts can be used as ash improvement agents will. Of these salts, the magnesium, calcium and ammonium salts are preferred.

The polysaccharide can be used either directly or in any other manner, e.g. B. by spraying, can be added.

The polysaccharide can be added to the smoking material before, during or after processing. The polysaccharide can be added to a complete smoking material for the production of tobacco foils be, or a gelation product of the polysaccharide i.i flat form can with the flat Tobacco smoking material are combined. In the manufacture of Calus tobacco, the Polysacckarid can be used in front of or added after shaping or before or after drying, followed by mixing can. The polysaccharide can also be used in the course of the manufacture of pipe tobacco and cigars or these Are added to products. In the case of cigarettes, the polysaccharide can also be used as a coating on the for Paper tubes used in the manufacture of cigarettes, or the · used to secure the paper used glue can be added.

The amount of polysaccharide used in this way depends on factors such as the type of using the polysaccharide tobacco products to be processed, the intended use, the desired taste etc., but in many cases 0.1 to 30% by weight of the polysaccharide is preferably obtained on the tobacco leaves, or about 0.05 to 25% by weight of polysaccharide, based on the weight of the smoking material, used. In particular, the polysaccharide is generally preferably used in an amount of about 0.1 to 10% by weight to improve the smoking properties, in an amount of about 0.5 to 15% by weight to improve physical properties and in a Mene; p of about I to 30 wt .-% to improve the binding capacity and other properties shafts of reconstructed tobacco, -, synthetic Tobacco etc. are used, which are generally other smoking material in a proportion of about 25% by weight. based on the weight of the total smoking material.

For addition to the cover sheets of cigars and paper tubes of cigarettes, tobacco filters, etc., it may be expedient to add about 30 to 200 g of a dispersion containing about 0.5 to 10% by weight of polysaccharide ^{per m 2}

ίο to be used by coating, spraying, etc. Further, a tobacco substitute can be made by using a fire regulator and the polysaccharide and used as a replacement for all or part of the smoking material

ι ϊ be.

The polysaccharide is used to replace known fuel materials in whole or in part. In In this case it is advisable to use 30 to 100% polysaccharide, calculated as purified material and based on the total amount of fuel, to which the polysaccharide used for the fuel may include to use.

Ais fire control are not burning and physiologically inactive inorganic compounds, e.g. B.

Oxides, hydroxides, carbonates, phosphates, sulfates. Aluminates, silicates, aluminosilicates etc. of alkali metals, like sodium and potassium, alkaline earth metals like calcium and magnesium and other metals like Zinc, aluminum, iron, titanium and silicon. Further
