Solution Overview

Problem

Existing methods for preparing dehydrated and de-alcoholized flavor compositions do not effectively remove water and ethanol without losing volatile aroma compounds, leading to a suboptimal enrichment of flavor compounds.

Innovation Solution

A method involving a dehydration process, preferably pervaporation using a hydrophilic membrane, followed by a dealcoholization process, such as distillation, to reduce water and ethanol content while preserving flavor compounds, resulting in a composition enriched in flavor compounds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If conventional dehydration and dealcoholization methods are used, then water and ethanol are removed from the flavor composition, but volatile aroma compounds are lost and flavor enrichment is suboptimal

Engineering Contradiction:
Improvewater and ethanol contentVSAvoidvolatile aroma compounds
Core Design Contradiction:
Quantity of substanceVSLoss of substance

Solution Approach 1:

The patent divides the separation process into two distinct stages: first dehydration to remove water, then dealcoholization to remove ethanol. This segmentation allows each process to be optimized independently, preventing the loss of volatile aroma compounds that occurs in conventional simultaneous removal methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies preliminary dehydration before dealcoholization. By removing water first through controlled evaporation, the subsequent ethanol removal process is enhanced in efficiency and selectivity, allowing preferential removal of ethanol over volatile aroma compounds.

Inventive Principle:
Principle #10Preliminary action

2Quantity of substance

If conventional removal methods are applied, then water and ethanol are decreased, but the flavor compounds are not sufficiently enriched

Engineering Contradiction:
Improvewater and ethanol contentVSAvoidflavor compound enrichment
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent utilizes parameter changes in the form of temperature control during the two-stage process. By carefully controlling temperature parameters during dehydration followed by dealcoholization, the process achieves selective removal of water and ethanol while preserving and concentrating the flavor compound profile.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If a single-stage removal process is used, then the process is simple, but it cannot selectively remove water and ethanol without losing aroma compounds

Engineering Contradiction:
Improveprocess complexityVSAvoidvolatile aroma compounds
Core Design Contradiction:
Device complexityVSLoss of substance

Solution Approach 1:

The patent segments the removal process into two sequential stages: dehydration followed by dealcoholization. This segmentation enables selective removal of different components (water then ethanol) while preserving volatile aroma compounds, overcoming the limitations of single-stage processes.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent maintains continuous useful action through sequential processing where the output of the first stage (dehydrated flavor composition) serves as the input for the second stage (dealcoholization). This continuous processing ensures complete removal of water and ethanol while maintaining flavor compound integrity.

Inventive Principle:
Principle #20Continuity of useful action
