Abstract

An oral tobacco raw material is easily handled during the manufacturing of oral tobacco, does not stain a packaging material when packaged as a pouch, and does not cause a feeling of a lump to a user and rapidly emits flavor when the user uses the pouch by placing it in the oral cavity. A method for manufacturing such an oral tobacco raw material, and a method for stably obtaining oral tobacco at low cost using the oral tobacco raw material are disclosed. A raw material chip for oral tobacco, includes a tobacco raw material composition including tobacco particles, water, and an additive, and a water-soluble edible film, the tobacco raw material composition and the water-soluble edible film being laminated, wherein outer surfaces of the raw material chip for oral tobacco are composed of a surface composed of the tobacco raw material composition, and a surface composed of the film.

First claim

What is claimed is:

1. A SNUS pouch filled with raw material chips for oral tobacco, comprising a tobacco raw material composition layer comprising tobacco particles, water, and an additive, and a water-soluble edible film, the tobacco raw material composition layer and the water-soluble edible film being laminated, wherein outer surfaces of the raw material chip for oral tobacco are composed of at least one surface composed of the tobacco raw material composition, and at least one surface composed of the film,
an average thickness of the layer comprising the tobacco raw material composition is 1 to 5 mm, and
a thickness of the water-soluble edible film is 1/20 to 1/100 of the average thickness of the layer comprising the tobacco raw material composition,
wherein the water-soluble edible film disposed on the tobacco raw material composition layer is completely dissolved in the oral cavity, and the strength of the raw material chips and the emission of flavor from the raw material chips is effectively maintained.

2. The SNUS pouch filled with raw material chips for oral tobacco according to claim 1 , wherein the water-soluble edible film is a film comprising a film raw material comprising one or more selected from the group consisting of pullulan, guar gum, soybean, agar, cellulose, alginic acid, carrageenan, pectin, amylose, amylopectin, gelatin, and casein.

3. The SNUS pouch filled with raw material chips for oral tobacco according to claim 2 , wherein the film raw material further comprises a perfume.

4. The SNUS pouch filled with raw material chips for oral tobacco according to claim 1 , wherein the chip has a quadrangular prism shape or a cylindrical shape.

5. The SNUS pouch filled with raw material chips for oral tobacco according to claim 1 , wherein the chip comprises one or more selected from the group consisting of sodium carbonate, potassium carbonate, sodium polyphosphate, and sodium hydrogen carbonate, as the additive.

6. The SNUS pouch of claim 1 , wherein, in the outer surfaces of the raw material chip, the area of the surface where the tobacco raw material composition is exposed is proportionally in a range of 0.1 to 0.8 with respect to the total outer area of the raw material chip.

7. The SNUS pouch of claim 1 wherein the average thickness of the layer comprising the tobacco raw material composition is 1 to 3 mm.

8. The SNUS pouch of claim 1 wherein the water included in the tobacco raw material composition is 20% by weight, based on the total amount of the tobacco raw material composition.
