Chlorogenic Acid Oral Composition With 4-Vinylguaiacol for Astringency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chlorogenic acid-based compositions exhibit strong astringency due to high caffeine content, which hinders continuous ingestion, and existing methods to mitigate this are inadequate.
Innovation Solution
Incorporating 4-vinylguaiacol at specific mass ratios with chlorogenic acid and caffeine, optionally combined with lactones, to suppress astringency in oral compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If chlorogenic acid reagent or low-roasting coffee bean is used as raw material to maximize chlorogenic acid content, then the physiological effects (antioxidant and hypotensive actions) are enhanced, but harshness and astringency increase making continuous ingestion difficult
Solution Approach 1:
The patent incorporates 4-vinylguaiacol, a compound naturally present in roasted coffee, to mask the harshness and astringency of high-concentration chlorogenic acid. By adding this aromatic compound at specific ratios (0.01-10% by mass relative to chlorogenic acid), the harmful sensory effects are converted into a pleasant drinking experience, enabling continuous ingestion while maintaining high chlorogenic acid content (5-50% by mass) for physiological benefits
Solution Approach 2:
The patent creates a composite beverage formulation combining multiple components: chlorogenic acid (5-50% by mass), 4-vinylguaiacol (0.01-10% by mass relative to chlorogenic acid), and optionally caffeine (0.001-0.4% by mass) with controlled mass ratios. This composite approach balances the harshness of chlorogenic acid with the aromatic properties of 4-vinylguaiacol, achieving both high efficacy and palatability
2Ease of manufacture
If roasting degree of coffee bean is increased to improve aroma and preference, then the aroma becomes richer and preference is improved, but a considerable amount of chlorogenic acid is decomposed
Solution Approach 1:
The patent extracts and isolates chlorogenic acid from coffee beans to obtain high-concentration chlorogenic acid (5-50% by mass in the final beverage) without subjecting it to high-temperature roasting that would decompose it. This extraction approach preserves the thermally labile chlorogenic acid while separately developing aroma compounds like 4-vinylguaiacol to provide the desired sensory profile
Solution Approach 2:
The patent changes the processing parameters by using low-roasting or unroasted coffee beans as raw materials to preserve chlorogenic acid, then compensates for the reduced natural aroma by adding purified 4-vinylguaiacol. This parameter change approach allows maintaining high chlorogenic acid content while achieving desirable aroma characteristics through controlled addition of specific compounds rather than high-temperature processing
