  • the oral tobacco product may exhibit a negative force of between -0.1N to 0.9N, preferably between -0.4N to -0.6N, in a three-point bending strength test.
  • Embodiments of the present invention also provide a preformed oral tobacco product comprising tobacco and a cellulose derivative as a binding agent.
  • the binding agent may comprise carboxymethyl cellulose, and the binding agent may consist exclusively of carboxymethyl cellulose.
  • the binding agent may be provided in the proportions defined above.
  • Embodiments of the present invention also provide an oral tobacco product which does not exhibit any brittleness and is substantially stable in water.
  • Such an oral tobacco product may further comprise any feature or characteristic or non-mutually exclusive combination thereof, defined above.
  • a first embodiment of the present invention comprises a soft and mouldable oral tobacco product comprising tobacco combined with a binding agent and extruded into continuous rods which are then cut into individual portions.
  • the product may additionally include further additives, such as, for example, flavourants and humectants.
  • a first method of the invention for producing such an oral tobacco product comprises combining moist snus tobacco with carboxymethyl cellulose ('CMC') as a binding agent at a proportion of 3% by weight.
  • the snus tobacco typically includes a number of additional components already mixed therewith, which may include salt, soda, humectants such as propylene glycol and/or glycerol, flavouring and water.
  • the moisture content of the snus is preferably around 55%. However, the moisture content is not limited to this value and may be from 30% - 60%, and 45% - 60%, or between 50% - 58%.
  • the mixture is then heated to around 60°C and kneaded for around 10 minutes.
  • the mixture is then extruded through a multiple orifice extruder (see Figure 1 ) - although other extruder configurations may be used within the scope of the invention - to form elongate strips of tobacco composition which are subsequently cut into individual portions (see Figures 2 and 3 ). It is to be noted that the invention is not intended to be limited to such a method including a heating step, and this step may be omitted.
  • a second method of the invention for producing oral tobacco products comprises feeding tobacco, and optionally other dry additives, into an extruding machine.
  • the tobacco may be milled or ground tobacco, or may be tobacco processed in any other way.
  • CMC as a binding agent is included at a proportion of 3% by weight.
  • the heated mixture is then fed through a die to form a continuous length of moist tobacco composition which is subsequently cut to desired lengths or individual portions.
  • the first extruder may be a gravimetric counter-rotating twin-screw extruder, or a single screw extruder.
  • the second extruder may be a twin-screw co-rotating extruder with variable heat zones and screw configurations, or a single screw with one heat zone.
  • the heat zones may be controlled to between 25°C - 150°C.
  • this method may not include any heating of the mixture from an external heat source and so the mixing process occurs at ambient temperature, for example 5°C - 20°C.
  • the resulting portions of tobacco product produced by both processes are soft and malleable, allowing them to easily be moulded by a user into a desired shape prior to insertion into the mouth in use.
  • the product does not show any brittleness.
  • TPB test Three-Point Bending test
  • Friability is a measurement of the tendency of an object to be reduced to smaller pieces when subjected to pressure or friction.
  • a numerical value for friability is the weight per cent of material lost when an individual product sample is placed within a friability drum and rotated at 25 rpm for 100 revolutions, which is equal to 4 minutes rotation.
  • a friability drum is a standard test apparatus comprising a drum with a diameter of 152 mm with an paddle which lifts and drops the sample product on each rotation of the drum. In the tests conducted, the friability test drum was a Copley 1000 tester drum, as shown in Figure 8 . Brittle products that have a tendency to chip or break will have a higher friability percentage value, whereas soft, mouldable products which do not readily chip or shatter exhibit much lower friability percentage values.
  • Tables 1 and 2 The numerical results of the friability of two sets of a number of samples of oral tobacco products of the invention are shown in Tables 1 and 2 below.
  • the first sample set was also subjected to TPB tests and these values are additionally shown in Table 1.
  • the results of further TPB tests of samples of oral tobacco products of the invention having differing compositions are shown in the graph of Figure 4 , which includes tobacco composition products with various binding agents including pectin, carrageennan, gellan, guar, hamulsion, hydroxypropyl methyl cellulose (HPMC), locust bean gum (LBG), sodium alginate, xanthan, agar, and CMC.
  • various binding agents including pectin, carrageennan, gellan, guar, hamulsion, hydroxypropyl methyl cellulose (HPMC), locust bean gum (LBG), sodium alginate, xanthan, agar, and CMC.
  • the graph plot for many compositions of tobacco product and binding agent have a curve profile which initially increases to a peak force value, after which point, the force plot drops. This signifies a product with an initial hardness before breaking, the peak of the graph being the break point, and indicates a brittleness to the products, after which break point, the force is reduced.
  • the invention is not intended to be limited to a tobacco product having this binding agent and other binding agents may also demonstrate such desirable properties, such as, for example, xanthan gum, pectin, locust bean gum, gellan, hydroxypropyl methyl cellulose (HPMC), guar gum, agar, carrageenan, tragacanth, sodium alginate or maltodextrin.
  • Another desirable physical property demonstrated by the tobacco composition products of the invention is that the preformed product does not, or substantially does not, stain the fingers of the user when being moulded and manipulated prior to use.
  • the tobacco composition products of the various formulations exhibit a maximum TPB test force of less than around 400g, equating to around 4N, consistent with the results in Table 1 discussed above.
  • the highest maximum TPB test value of the products tested was achieved with the product made from coarse stem tobacco.
  • the tobacco products of the invention are not limited to such values, however, and some embodiments with varying types of dry tobacco, and CMC binding agent percentage by weight, may have a three-point bending strength less than 2.5N, less than 0.5N, and also less than 0.25N.
  • the loose tobacco used in the manufacture of the tobacco products of the invention and in the processes described above, is preferably relatively fine in size, and snus tobacco or other fine grade tobacco is preferred.
  • the tobacco products of the invention are also stable in water for at least 30 minutes, and preferably one hour, and substantially do not break down, dissolve, or otherwise lose product mass as do some known smokeless oral tobacco products. This results in a product which maintains its integrity and shape during three phases of consumer use (insertion, use and removal), making it convenient to use and also clean and convenient to dispose of after use.
  • Samples 1, 2, 3 and WC were then drained through a sieve on top of their respective fleece.
  • Sample DC was then weighed ("weight 1"). All samples were then arranged on sieve and placed in oven at 29 degree Celsius. Samples were then dried for over 12 hours (22 actual). Samples were then weighed and data recorded ("weight 2" - see Table 3 below).
  • the weight loss for each sample was then calculated and recorded.
  • the percentage weight loss for each sample was then compared with that for the wet control, using an "average portion weight” (APW) value of finished products.
  • APIW average portion weight
  • a further advantage of the tobacco products of the invention is that they may provide a flavour delivery comparable to that of loose snus without the inconvenience of small particles being spread around the inside of the mouth which can get caught in the gums/teeth, and the messy disposal after use, as is the case with loose snus and hard smokeless tobacco products.
  • the products provide the convenience of pouched snus but without the requirement for the tobacco product to be contained within a pouch and the disadvantages that may be associated with pouched snus products.
  • the mixture is described as being heated to around 60°C, although this temperature may vary, for example between 5°C and 70°C, or 50°C.
  • the mixture may not need to be heated at all and the heating step of the process may be omitted entirely. In such a case, the mixture is processed at an ambient temperature of between 5°C and 20°C.
  • the kneading step is described as being performed for around 10 minutes, the process of the invention is not intended to be limited to this duration and other kneading times may be used, for example, between 3-20 minutes, preferably between 7 - 15 minutes.
  • the binder is described as being added at a proportion of around 3% by weight, although the invention is not limited to this proportion, and may be between 1% - 5%, preferably between 2% - 4%. It has been found that a binding agent proportion less than 1% does not bind the tobacco together in the finished product to the required level, whereas a binding agent proportion more than 5% may result in undesirable product characteristics.
  • the above binding agent proportions apply to CMC as a binding agent but the invention is not intended to be limited to a tobacco product having this binding agent and other binding agents, such as those listed above, in such proportions, may also demonstrate such desirable properties.
  • the extruding of the continuous lengths of tobacco product may alternatively be different to that of the processes described above, and may alternatively comprise extruding a wide belt of material (see Figure 5 ) then shaping using a cutter/scorer (see Figure 6 ). Yet further, the product may be shaped and formed into individual dosages by being passed through double rollers (see Figure 7 ). Yet further, the product may be shaped and formed into individual dosages by being extruded into half-dies then pressed together.
