Solution Overview

Problem

Existing smokeless tobacco products lack translucency while maintaining tobacco flavor, and there is a need for improved processes to prepare tobacco-containing compositions suitable for oral consumption.

Innovation Solution

A smokeless tobacco product comprising a tobacco extract with a sugar substitute forming a glassy matrix, where the extract is ultrafiltered to remove high molecular weight components, and optionally heat-treated to enhance clarity, resulting in a translucent or transparent product.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If tobacco extract is included in smokeless tobacco product, then tobacco flavor is maintained, but translucency is reduced

Engineering Contradiction:
Improvetobacco flavor contentVSAvoidtranslucency
Core Design Contradiction:
Quantity of substanceVSIllumination intensity

Solution Approach 1:

The patent extracts and removes high molecular weight components (proteins, polysaccharides, pigments) from the tobacco extract through ultrafiltration and heat treatment processes. This selective removal preserves the desirable tobacco flavor compounds while eliminating the components that cause opacity and discoloration, thereby resolving the contradiction between maintaining flavor and achieving translucency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies heat treatment at controlled temperatures (e.g., 60-100°C) to modify the physical and chemical properties of the tobacco extract. This heat treatment denatures proteins and precipitates pigments, changing the extract's optical properties to improve translucency while maintaining flavor. The process optimizes temperature and time parameters to achieve the desired balance between clarity and flavor retention.

Inventive Principle:
Principle #35Parameter changes

2Illumination intensity

If heat treatment is applied to tobacco extract, then clarity is enhanced, but acrylamide formation risk increases

Engineering Contradiction:
ImproveclarityVSAvoidacrylamide formation
Core Design Contradiction:
Illumination intensityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the potential harmful effect of heat treatment (acrylamide formation) into a beneficial process by carefully controlling treatment conditions. By using moderate temperatures (60-100°C) rather than high-temperature frying or roasting, and by limiting treatment time, the process achieves clarity enhancement through protein denaturation and pigment precipitation while minimizing the formation of harmful acrylamide compounds.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent optimizes heat treatment parameters (temperature, time, pH, moisture content) to achieve the desired clarity while minimizing harmful byproducts. By maintaining temperature below 100°C and controlling treatment duration, the process achieves sufficient clarification without creating excessive acrylamide, thus resolving the contradiction between clarity enhancement and harmful factor reduction.

Inventive Principle:
Principle #35Parameter changes

3Illumination intensity

If ultrafiltration is used to remove high molecular weight components, then translucency is improved, but manufacturing complexity increases

Engineering Contradiction:
ImprovetranslucencyVSAvoidmanufacturing process complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent segments the complex ultrafiltration process into manageable stages: initial concentration, ultrafiltration through specific molecular weight cutoff membranes (e.g., 10,000-100,000 Da), and subsequent heat treatment. This segmentation allows each step to be optimized independently and facilitates integration with existing manufacturing equipment, reducing overall process complexity while achieving the desired translucency improvement.

Inventive Principle:
Principle #1Segmentation
