Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The art of flavor and fragrance prediction is in its infancy, and small structural changes in molecules can have profound effects on their aroma or fragrance profile, making it difficult to identify effective ingredients for enhancing scents and tastes in consumer products.
Innovation Solution
The use of 3-phenylpropiolic acid and its esters, such as ethyl 3-phenylpropiolate, as new fragrance and flavor ingredients, which exhibit surprising olfactive qualities like alcoholic, fermented, and fruity aromas, suitable for various consumer products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If new fragrance and flavor ingredients are identified through traditional methods, then the aroma and flavor profiles can be enhanced, but the process is time-consuming and uncertain due to the difficulty in predicting the effects of small structural changes
Solution Approach 1:
The patent applies parameter changes by systematically modifying molecular structure parameters (adding functional groups like aldehydes, alcohols, esters; varying carbon chain lengths; introducing aromatic rings) to the core 3-phenylpropiolic acid structure. This allows prediction of aroma and flavor outcomes based on known structure-odor relationships, reducing the time and uncertainty of ingredient identification while maintaining reliability.
2Reliability
If complex molecular structures are used to achieve unique aroma profiles, then the fragrance quality improves, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent segments the fragrance development process into a systematic approach: starting with a core structure (3-phenylpropiolic acid) and adding specific functional group segments (aldehyde, alcohol, ester groups) to achieve desired aroma profiles. This segmentation allows for controlled complexity, where each functional group contributes predictable sensory characteristics, balancing fragrance quality with manufacturability.
Solution Approach 2:
The patent uses parameter changes to optimize the balance between molecular complexity and fragrance quality. By systematically varying parameters such as the type of functional group, carbon chain length, and aromatic substitution patterns, the invention achieves unique aroma profiles while maintaining structures that are feasible to synthesize and manufacture.
3Adaptability or versatility
If multiple derivative compounds are synthesized to explore different scent profiles, then the versatility of fragrance options increases, but the manufacturing process becomes more complex
Solution Approach 1:
The patent applies universality by developing a platform approach where 3-phenylpropiolic acid serves as a universal core structure that can be derivatized through common chemical transformations. The same synthetic methodology can produce multiple fragrance derivatives with different aroma profiles (floral, fruity, spicy, woody), making the manufacturing process versatile yet standardized, thereby maintaining ease of manufacture while increasing fragrance profile variety.
