Menthol Aroma Preparations for Masking Eugenol Burn
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Many individuals dislike the taste of eugenol and related substances due to their warm, spicy and burning or painful sensation, which is often associated with dental visits, and there is a need to modify these substances to enhance the warm-spicy impression while suppressing the burning-painful sensation.
Innovation Solution
A combination of compounds of formula (I) with menthol and menthyl acetate in specific weight ratios, along with additional flavorings and sweeteners, is used to create flavor preparations that maintain a warm-spicy sensation without the burning or painful experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional aroma preparations are used, then aroma release occurs, but the release is uncontrolled and inconsistent
Solution Approach 1:
The invention divides the aroma preparation system into distinct functional components: encapsulated aroma compounds (core), biodegradable matrix material (shell), and controlled release agents. This segmentation allows each component to perform its specific function - the matrix controls the release rate while the aroma compounds are protected until release is triggered, thereby achieving controlled and consistent aroma release.
Solution Approach 2:
The aroma compounds are pre-encapsulated within the biodegradable matrix before application. This preliminary encapsulation action prepares the aroma compounds for controlled release by embedding them in a matrix that will degrade at a predetermined rate, ensuring consistent release patterns without requiring complex real-time control mechanisms.
2Quantity of substance
If high concentrations of aroma compounds are used, then aroma intensity increases, but stability and shelf life decrease
Solution Approach 1:
The biodegradable matrix acts as an intermediary between the aroma compounds and the external environment. It encapsulates high concentrations of aroma compounds, protecting them from degradation while allowing controlled release. This mediator enables the system to maintain both high aroma compound concentrations and long-term stability simultaneously.
Solution Approach 2:
The invention changes the physical state and accessibility of aroma compounds by embedding them in a solid biodegradable matrix. This parameter change from free-floating to encapsulated state increases stability while the controlled degradation of the matrix gradually releases the aroma compounds, maintaining intensity over time.
3Ease of manufacture
If synthetic aroma compounds are used, then cost is reduced, but naturalness and consumer acceptance decrease
Solution Approach 1:
The invention uses composite materials consisting of naturally derived biodegradable polymers (such as polysaccharides, proteins, or lipids) combined with aroma compounds. This composite approach maintains the naturalness perceived by consumers while enabling controlled release functionality that would be difficult to achieve with pure natural materials, thereby balancing consumer acceptance with manufacturing efficiency.
4Speed
If aroma compounds are released quickly, then initial aroma impact is strong, but duration of release is short
Solution Approach 1:
The biodegradable matrix provides periodic action through its gradual degradation process. As the matrix degrades over time, it releases aroma compounds in a sustained periodic manner, maintaining consistent aroma levels throughout the intended duration rather than releasing all compounds at once. This creates both initial impact and extended duration.
Solution Approach 2:
The invention exploits phase transitions of the biodegradable matrix material as it degrades from intact to broken down state. This phase transition process controls the release kinetics, allowing the system to maintain a balance between release rate and duration by adjusting the degradation characteristics of the matrix material.
