Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for evaluating aroma components do not adequately account for changes in aroma diffusion characteristics due to temperature, shape, or concentration over time, making it difficult to create formulated flavors and fragrances with controlled aroma expressions.
Innovation Solution
An evaluation method that measures the rate of increase in aroma concentration over time in a model environment, such as an oral cavity or product usage scenario, using instruments like PTR-TOFMS, to objectively assess aroma diffusion characteristics and adjust the prescription ratio of aroma components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional aroma evaluation methods are used, then the evaluation process is simple, but the measurement precision of aroma diffusion characteristics is insufficient
Solution Approach 1:
The patent replaces conventional sensory evaluation methods with instrumental analysis using PTR-TOFMS (proton transfer reaction time-of-flight mass spectrometry). This substitution enables objective, quantitative measurement of aroma component concentrations over time, significantly improving measurement precision while accepting increased system complexity
Solution Approach 2:
The patent creates a model oral cavity environment that replicates the actual consumption conditions. By copying the physical and chemical conditions of the oral cavity (temperature, saliva presence, mixing dynamics), the system can measure aroma diffusion characteristics in a controlled setting that accurately reflects real-world performance
2Reliability
If repeated aroma checking procedures are performed, then the reliability of flavor and fragrance formulation is improved, but the productivity of the development process decreases
Solution Approach 1:
The patent performs preliminary evaluation of individual aroma components and their diffusion characteristics before final formulation assembly. By measuring how each component behaves in the model oral cavity environment beforehand, the system can predict overall formulation performance, reducing the need for repeated full-formulation testing and accelerating development
Solution Approach 2:
The patent implements a feedback mechanism where PTR-TOFMS continuously monitors aroma component concentrations over time during evaluation. This real-time data provides feedback on diffusion rates and temporal patterns, enabling formulation adjustments based on quantitative performance metrics rather than subjective sensory assessment
3Adaptability or versatility
If aroma components are evaluated in isolation, then the measurement process is simplified, but the adaptability to actual consumption conditions is reduced
Solution Approach 1:
The patent applies local quality by creating specific micro-environments within the model oral cavity system. Different regions or conditions (e.g., presence/absence of saliva, different temperatures) can be independently controlled to study how local conditions affect aroma diffusion, allowing evaluation of components under various consumption scenarios

AI summary
The present invention pertains to an aroma component assessment method and a method for preparing a fragrance composition using said assessment method. The present invention provides a fragrance composition appropriate for a product in consideration of usage conditions of the product. For that purpose, the present invention involves: making measurements of the rate of concentration increase (i.e., detection quantity a of aroma component after lapse of a predetermined time after start of measurement/detection quantity b of aroma component immediately after the start of detection) of aroma released within a prescribed time range for each of two or more types of aroma components contained in a product within a consumption environment of said product or within a model environment thereof; and assessing the impact of the aroma components contained in the product on fragrance impressions of the product, using the magnitude relationship in the aroma concentration increase rate of the two types or more aroma components, as an index correlated with the magnitude relationship of the impacts on fragrance impressions of the product, so as to make objective and appropriate assessments of the impacts of the aroma components contained in the product on fragrance impression.
