Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing purified chlorogenic acid-containing compositions are limited by the caffeine-selective removing capacity of porous adsorbents, which restricts the treatable solids amount of chlorogenic acid-containing materials per unit amount of adsorbent.
Innovation Solution
A method involving a chlorogenic acid-containing composition with a solids concentration of 1.5 to 4.7 mass% and a caffeine/chlorogenic acid mass ratio of 0.001 to 2.5, contacted with a porous adsorbent at 50°C to 100°C, enhances the caffeine-selective removing property and increases the treatable solids amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional methods use porous adsorbents to remove caffeine from chlorogenic acid-containing compositions, then caffeine removal is achieved, but the treatable solids amount per unit amount of adsorbent is limited
Solution Approach 1:
The patent applies parameter changes by optimizing the solids concentration of the chlorogenic acid-containing composition to a specific range (1.5-4.7 mass%) and controlling the caffeine/chlorogenic acid mass ratio (0.001-2.5). These parameter adjustments enhance the caffeine-selective removing property of the porous adsorbent, allowing increased treatable solids amount per unit amount of adsorbent while maintaining high caffeine removal efficiency.
2Quantity of substance
If the solids concentration of chlorogenic acid-containing composition is increased, then more material can be processed, but the caffeine-selective removing capacity of the adsorbent decreases
Solution Approach 1:
The patent resolves this contradiction by identifying and applying optimal parameter ranges: solids concentration of 1.5-4.7 mass% and caffeine/chlorogenic acid mass ratio of 0.001-2.5. Within these parameters, the adsorbent maintains high caffeine-selective removing capacity while enabling increased solids concentration for more efficient processing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach effectively increases the treatable solids amount of chlorogenic acid-containing material per unit of porous adsorbent while maintaining a high caffeine removal efficiency, producing a purified chlorogenic acid composition with improved yield and quality.
Implementation Method 1
When a chlorogenic acid-containing composition is brought into contact with a porous adsorbent, such as activated carbon or clay, the porous adsorbent adsorbs and removes not only caffeine
