Description

EXAMPLES

Example 1: Preparation of Nicotine-Coated Non-Tobacco Plant Material

[0050] In this Example, the non-tobacco plant material is coated with nicotine using a liquid nicotine-in-glycerol solution, wherein the nicotine-in-glycerol solution is sprayed on the non-tobacco plant material in a fluidized bed process. Alternatively, the non-tobacco plant material can be coated with nicotine using a liquid nicotine-in-glycerol solution in a drum coating process.

[0051] a) 600 g wheat fibres (WF 200 provided as VITACEL by J. Rettenmaier & Söhne GmbH & Co KG, DE) are spray coated with 350 g nicotine-in-glycerol solution (10 weight-% nicotine in glycerol, provided by Siegfried Ltd, CH) in a fluidized bed process.

[0052] The desired amount of nicotine-in-glycerol solution was successfully coated onto the wheat fibres to give a product of approx. 910 g of nicotine-coated wheat fibres with a nicotine content of approx. 3.8 weight-% based on the total weight of the nicotine-coated wheat fibres.

[0053] b) 600 g wheat fibres (WF 200 provided as VITACEL by J. Rettenmaier & Söhne GmbH & Co KG, DE) are spray coated with 264 g nicotine-in-glycerol solution (10 weight-% nicotine in glycerol, provided by Siegfried Ltd, CH) in a fluidized bed process.

[0054] The desired amount of nicotine-in-glycerol solution was successfully coated onto the wheat fibres to give a product of approx. 860 g of nicotine-coated wheat fibres with a nicotine content of approx. 3.1 weight-% based on the total weight of the nicotine-coated wheat fibres.

[0055] c) 600 g wheat fibres (WF 200 provided as VITACEL by J. Rettenmaier & Söhne GmbH & Co KG, DE) are spray coated with 450 g nicotine-in-glycerol solution (10 weight-% nicotine in glycerol, provided by Siegfried Ltd, CH) in a fluidized bed process.

[0056] The desired amount of nicotine-in-glycerol solution was successfully coated onto the wheat fibres to give a product of approx. 1043 g of nicotine-coated wheat fibres with a nicotine content of approx. 4.3 weight-% based on the total weight of the nicotine-coated wheat fibres.

Example 2: Manufacturing of a First Filling Material According to the Invention for Use in an Oral Pouched Smokeless Product

[0057] In an exemplary embodiment, a method is disclosed of manufacturing a filling material of the invention. Said method is based on mixing nicotine-coated non-tobacco plant material with further ingredients and tobacco material derived from tobacco stalk, tobacco root, tobacco flower or a combination thereof in order to form a filling material suitable for use in an oral pouched smokeless product.

[0058] An exemplary method for producing a batch of a filling material for use in an oral pouched smokeless product comprises the step of mixing the following ingredients: [0059] 135 kg nicotine-coated wheat fibres of Example 1 a), b) or c); [0060] 6.5 kg tobacco material (optionally pasteurized) derived from tobacco stalk, tobacco root, tobacco flower or a combination thereof, preferably non-bleached tobacco material; [0061] 78 kg water; [0062] 10.4 kg NaCl; [0063] 12.06 kg ammonium chloride (20%); [0064] 1.18 kg sodium carbonate; [0065] 5.6 kg propylene glycol; and

[0066] optionally flavour.

[0067] All ingredients are added in a single vessel and mixed. The resulting filling material may be partitioned and packaged into oral pouched smokeless products.

Example 3: Manufacturing of a Second Filling Material According to the Invention for Use in an Oral Pouched Smokeless Product

[0068] In an exemplary embodiment, a method is disclosed of manufacturing a filling material of the invention. Said method is based on mixing tobacco material derived from tobacco stalk, tobacco root, tobacco flower or a combination thereof with further ingredients in order to form a tobacco filling material suitable for use in an oral pouched smokeless product.

[0069] An exemplary method for producing a batch of a filling material for use in an oral pouched smokeless product comprises the step of mixing the following ingredients: [0070] 135 kg tobacco material (optionally pasteurized) derived from tobacco stalk, tobacco root, tobacco flower or a combination thereof; [0071] 118 kg water; [0072] 13.75 kg NaCl; [0073] 5.98 kg ammonium chloride (20%); [0074] 2.3 kg sodium carbonate; [0075] 12.34 kg propylene glycol; and

[0076] optionally flavour.

[0077] All ingredients are added in a single vessel and mixed. The resulting filling material may be partitioned and packaged into oral pouched smokeless products.
