Solid Oral Composition for Masking Branched Fatty Acid Odor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Branched fatty acids, such as isovaleric acid, are known to cause unpleasant odors, and existing technologies have not effectively addressed this issue in oral compositions.
Innovation Solution
Incorporating pyrazines at a specific mass ratio with branched fatty acids suppresses the unpleasant odor, with additional suppression of 4-vinylguaiacol when coexisting with the branched fatty acids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If branched fatty acids are incorporated into the oral composition, then the flavor complexity is improved, but an unpleasant odor is generated
Solution Approach 1:
Pyrazines are introduced as an intermediary substance that mediates between the branched fatty acid and the human olfactory system. The pyrazines interact with the branched fatty acid molecules and transform the unpleasant odor perception into a pleasant roasted or nutty flavor profile, effectively acting as a chemical mediator that converts harmful sensory input into beneficial output
Solution Approach 2:
The invention converts the harmful unpleasant odor of branched fatty acids into a beneficial roasted or nutty flavor by combining them with pyrazines. The specific mass ratio relationship (pyrazines to branched fatty acids from 0.015 to 5) transforms what would normally be a defective sensory attribute into a desirable flavor characteristic, thereby converting harm into benefit
2Object-generated harmful factors
If pyrazines are added to suppress the unpleasant odor of branched fatty acids, then the odor suppression effect is improved, but the device complexity increases
Solution Approach 1:
The invention optimizes the mass ratio parameter between pyrazines and branched fatty acids to achieve effective odor suppression while minimizing composition complexity. By establishing specific ratio ranges (0.015 to 5, with preferred ranges of 0.05 to 1), the patent transforms a complex multi-component problem into a manageable parameter optimization task, where adjusting the ratio alone controls the suppression effectiveness
3Ease of manufacture
If multiple aroma components are incorporated to enhance flavor, then the palatability is improved, but the manufacturing precision requirement increases
Solution Approach 1:
The patent simplifies manufacturing precision requirements by establishing broad acceptable ratio ranges between pyrazines and branched fatty acids (0.015 to 5). This parameter approach allows significant flexibility in formulation while maintaining effective odor suppression and flavor enhancement, thereby reducing the stringency of manufacturing control compared to fixed-ratio formulations
