Smokeless Oral Product With Low-Density Particles for Softer Mouthfeel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smokeless oral products, such as snuff and snus, often cause irritation at the back of the throat and have a dense, compact structure that affects user experience and mouthfeel.
Innovation Solution
Incorporating a particulate material with specific properties, including a mass median particle size of 0.3 mm to 3 mm, bulk density less than 0.6 g/cm³, and a combined starch and sugar content of less than 7%, into smokeless oral products to improve mouthfeel and reduce throat irritation.

1Object-affected harmful factors
If a dense, compact structure is used in smokeless oral products, then the product maintains its shape and stability, but it causes irritation at the back of the throat and poor mouthfeel
Solution Approach 1:
The product is divided into discrete particles with specific size ranges (0.3-3mm mass median particle size). This segmentation creates a less dense overall structure that reduces throat irritation while maintaining individual particle stability. The particulate material forms a heterogeneous mixture that prevents the dense compact structure associated with throat irritation.
Solution Approach 2:
Different regions of the product have different properties - the particulate material provides localized softness and springiness at the particle level, while the overall product maintains structural stability through the specific particle size distribution and density characteristics. This local quality differentiation allows simultaneous improvement of mouthfeel and structural stability.
2Ease of operation
If particulate material with specific properties is added to improve mouthfeel, then user experience is enhanced, but the product composition becomes more complex
Solution Approach 1:
The invention specifies particular parameter ranges for the particulate material (particle size 0.3-3mm, bulk density <0.6 g/cm³, starch+sugar content <7%) to achieve improved mouthfeel. By controlling these physical and chemical parameters within defined ranges, the product achieves desirable sensory properties while maintaining compositional simplicity through natural particulate materials.
Solution Approach 2:
The product combines tobacco or tobacco analogue material with particulate material to create a composite formulation. This composite approach integrates the functional properties of tobacco with the textural benefits of particulate material, achieving enhanced mouthfeel through material composition rather than complex processing or multiple additives.
3Ease of operation
If the particle size is reduced to improve texture, then the mouthfeel becomes softer, but the bulk density increases and throat irritation worsens
Solution Approach 1:
The invention employs a dynamic particle size distribution rather than a single fixed size. The mass median particle size range of 0.3-3mm allows flexibility in achieving both soft texture and acceptable bulk density. This dynamic range enables optimization of both texture softness and bulk density depending on specific product requirements.
Solution Approach 2:
The invention addresses the density-texture tradeoff by introducing particle shape and size distribution as additional dimensions of control. Rather than simply reducing particle size (one dimension), the patent utilizes the three-dimensional characteristics of particulate material including size distribution, shape, and packing arrangement to achieve soft texture while maintaining lower bulk density through optimized particle morphology.
