Definitions

  • the present invention relates to a method of producing a snuff composition for oral use and a snuff composition produced by the method.
  • Smokeless tobacco for oral use includes chewing tobacco, dry snuff and moist (wet) snuff.
  • dry snuff has a moisture content of less than 10 wt% and moist snuff has a moisture content of above 40 wt%.
  • Semi-dry products having a moisture content between 10 wt% to 40 wt% are also available.
  • the snuff preparation In production processes typically used today for producing pouched snuff products, the snuff preparation normally has a water content within the range of from about 22 to about 44 wt%. Generally, additional water, salt, pH adjuster and additional ingredients, such as flavours, are added to the snuff preparation after the heat-treatment in order to provide a final smokeless snuff composition, such as a moist snuff composition.
  • the pasteurization step is currently often carried out in batches in a pasteurization pot.
  • the snuff composition is blended with water, salt, ph-regulators and heated while being mixed.
  • Previous pasteurization methods include mixing the snuff and providing the snuff in barrels which are placed in an oven, such pasteurization did not involve mixing of the snuff during the pasteurization process.
  • the heated snuff composition may be cooled in a cooling facility or the pasteurization pot may be equipped with a cooling unit.
  • the current snuff production is well functioning but is limited by being produced in batches. Furthermore, the subsequent step of cooling the snuff composition after pasteurization takes long time and requires lots of energy.
  • the present disclosure relates to a method of producing a snuff composition for oral use, the method comprising the following steps:
  • oral use refers to the use of the snuff composition in contact with mucous membranes in the oral cavity, such as buccal placement of the snuff composition.
  • the first heating step may for example be carried out by means of hot air, steam, radiation, electric heating, microwaves, or any combination thereof.
  • the moving conveyor belt may be heated, which may be the sole source of heat or which may be combined with a top heating system, such as in combination with hot air, steam, radiation, electric heating and/or microwaves.
  • the first heating step reduces the microorganism content of the initial snuff composition and thus provides a heat-treated snuff composition having reduced microorganism content.
  • the first heating step may reduce the microorganism content of the initial snuff composition with at least 50%, such as at least 70%, at least 80%, at least 90%, at least 95% or at least 99%.
  • the first heating step may provide a heat-treated tobacco preparation having less than 10 000 colony forming units (CFU) of microorganisms, such as bacteria, per gram, measured for example by a spread plate method.
  • CFU colony forming units
  • the initial snus composition may be constituted by or comprise grinded, cut or shredded tobacco and/or non-tobacco plant material.
  • the initial snuff composition is provided in a layer on the conveyor belt, such as in grinded, cut or shredded form and has not been packed in pouch material.
  • the initial snuff composition may be added to a conveyor belt in a snuff composition layer, such as an evenly distributed snuff composition layer, and the conveyor belt may subsequently move into the oven for the first heating step or the initial snuff composition may be directly introduced into the oven and onto the moving conveyor belt.
  • the oven may be a closed oven, such as a heating tunnel.
  • the capacity, efficiency and flexibility of the method may be increased. Since the snuff is not produced batch wise but instead continuously on a moving conveyor belt, both the amount of snuff composition and the type of snuff composition produced may be adapted more easily. If for example different types of snuff, such as with differing flavors, are desired, the amounts which can currently be produced are determined by the batch size. A further drawback with the batch wise production is that if a smaller amount of snuff for a certain flavor is desired, the pasteurization pot will not be completely filled up, thereby reducing the efficiency of the method.
  • the method may comprise a step d) of mixing the snuff composition, step d) being carried out between step b) of depositing the initial snuff composition on the moving conveyor belt and step c) of moving the initial snuff composition through the oven, or step d) may be carried out during step c).
  • the method may include one or more mixing steps, such as two or more mixing steps.
  • the method may include one to five mixing steps.
  • the mixing step d) may be carried out by allowing the snuff composition being transported on a first section of the moving conveyor belt to fall onto a second section of the moving conveyor belt or alternatively onto a second moving conveyor belt and/or by means of the moving conveyor belt comprising a shaking transport section and/or being mixed in a mixing drum.
  • a mixing step which is carried out during pasteurization while the initial snuff composition is being transported through the oven is highly efficient in terms of time saved as no separate mixing step is necessary.
  • the method may comprise a cooling step e) wherein the pasteurized snuff composition is cooled down in a cooling section.
  • cooling time for the snuff composition may be greatly reduced as well as the energy consumption for the cooling step.
  • the pasteurized snuff composition may be cooled down in the cooling section while being transported on the moving conveyor belt, optionally during a time range of from 1 minute to 5 hours, such as during a time period within the range of from 15 minutes to 5 hours.
  • the chilling section may for example comprise a chilling tunnel.
  • the cooling of the snuff composition may for example be made by cooling of the conveyor belt and/or by cooled air and/or by liquid nitrogen and/or liquid carbon dioxide and/or carbon dioxide from in the solid state, i.e. dry ice.
  • a considerably longer time is required for chilling the pasteurized snuff composition as whole volume of the batch is cooled down at the same time.
  • the pasteurization pot is used as a chilling pot after the pasteurization step to reduce the number of method steps.
  • the snuff composition may be transported in a moving transport belt, either the same as during pasteurization or a separate moving transport belt, in room temperature and may be cooled down without being exposed to chilling temperatures.
  • the pasteurized and cooled snuff composition may exit the cooling section on the moving conveyor belt.
  • Flavours may be added to the snuff composition after exiting the cooling section. Since the method of producing is a continuous method, the flexibility in terms of the amount of snuff composition with different flavour which may be produced is improved. Hence, if there is a desire to prepare a larger amount of a snuff composition with a certain flavour and a smaller amount with another flavour this may easily by customized with a method according to the present disclosure.
  • the temperature of the snuff composition during the first heating step may be within the range of from 70°C to 100°C for a time period of at least 30 minutes, such as at least 1 hour, at least 3 hours or at least 5 hours, optionally for a time period within the range of from 30 minutes to 24 hours, such as within the range of from 1 hour to 10 hours.
  • the water may be continuously or discontinuously added to the snuff composition during the first heating step by spraying, steaming, dripping or pouring the water onto the snuff composition during the entire step of during parts of the heating step, in order for the snuff composition to maintain a certain moisture content during the heating step.
  • the snuff composition should not be completely dry and water may be added either prior to the pasteurization step in an amount keeping it moist during the pasteurization step and/or water may continuously or discontinuously be added during the pasteurization.
  • An advantage with continuous of discontinuous addition of water during the pasteurization step is that a relatively constant moisture level may be kept in the snuff composition throughout the pasteurization step.
  • the water may be added in an amount within the range of from 10 to 75 wt%, such as in an amount within the range of from 15 wt% to 70 wt% of the snuff composition.
  • the moisture content of the snuff composition during the first heating step may be within the range of from 3 wt% to 70 wt%, such as within the range of from 5 wt% to 60 wt%, such as within the range of from 10 wt% to 58 wt% or within the range of from 10 wt% to 56 wt%, optionally within the range of from 15 wt% to 56 wt%.
  • moisture content refers to the total amount of oven volatile ingredients, such as water and other oven volatiles (e.g. propylene glycol) in a preparation, composition or product.
  • the moisture content is given herein as percent by weight (wt%) of the total weight of the preparation, composition or product.

Helrich (ed ).
  • the moisture content is determined gravimetrically by taking 2.5 ⁇ 0.25 g sample and weighing the sample at ambient conditions, herein defined as being at a temperature of 22°C and a relative humidity of 60%, before evaporation of moisture and after completion of dehydration.
  • Mettler Toledo's Moisture Analyzer HB43 a balance with halogen heating technology, is used (instead of an oven and a balance as in the mentioned literature references) in the experiments described herein.
  • the sample is heated to 105°C (instead of 99.5 ⁇ 0.5°C as in the mentioned literature references).
  • the measurement is stopped when the weight change is less than 1 mg during a 90 seconds time frame.
  • the moisture content as weight percent of the sample is then calculated automatically by the Moisture Analyzer HB43.
  • the initial snuff composition may be deposited onto the moving conveyor belt such that a layer of the initial snuff composition is formed, the layer may have a thickness of up to 100 mm is formed, optionally a thickness within the range of from 1 mm to 100 mm, optionally wherein the thickness of the layer is up to 70 mm, such as up to 50 mm.
