Insoluble Polymer Extraction of Pro-Oxidizing Cations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current antioxidant solutions in the food, cosmetics, and pharmaceutical industries are ineffective in completely blocking oxidation in organic compositions, as they either oxidize themselves or have limitations in time, and their residues can cause health issues.
Innovation Solution
A method involving the use of insoluble negatively charged organic polymers, such as pectic acid and alginic acid, to bind and remove pro-oxidizing cations from organic compositions, thereby reducing their oxidizing power and preventing oxidation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional antioxidants (sulfites, vitamin C, glutathione) are added to block oxidation, then oxidation of organic molecules is delayed or prevented, but the antioxidants remain in the composition causing health problems and generating intolerance
Solution Approach 1:
The patent removes pro-oxidizing cations from the composition by having them bind to an insoluble polymer matrix, effectively extracting the harmful oxidizing agents from the system. This eliminates the need for antioxidant additives that would otherwise remain in the composition and cause health issues.
Solution Approach 2:
The insoluble polymer acts as an intermediary that binds pro-oxidizing cations, preventing them from oxidizing organic molecules. This mediator approach allows oxidation protection without introducing harmful antioxidant residues into the final product.
2Duration of action of moving object
If antioxidants are added to control oxidation, then oxidation of organic molecules is limited, but the antioxidants themselves are eventually oxidized and lose their protective action over time
Solution Approach 1:
By extracting pro-oxidizing cations from the composition through binding to the insoluble polymer, the patent eliminates the oxidizing agents that would otherwise deplete antioxidants over time. This removes the fundamental cause of oxidation rather than relying on consumable antioxidants.
Solution Approach 2:
The insoluble polymer continuously binds pro-oxidizing cations as they are released or formed in the composition, providing ongoing protection without being consumed or oxidized itself. The polymer's insolvability ensures it remains stable and functional throughout the product's shelf life.
3Object-affected harmful factors
If acids (citric acid, benzoic acid) are used to slow oxidation by affecting polyphenol oxidase, then oxidation is reduced at acidic pH, but pro-oxidizing cations are solubilized and oxidation is not completely blocked
Solution Approach 1:
The insoluble polymer serves as an intermediary that directly binds pro-oxidizing cations, providing a more effective mechanism than acid-based inhibition. This binding action completely removes the cations from solution, preventing both enzymatic and non-enzymatic oxidation pathways.
Solution Approach 2:
The patent changes the approach from pH modification to direct cation binding. By using an insoluble polymer with binding sites for pro-oxidizing cations, the system achieves complete oxidation blocking regardless of pH conditions, overcoming the limitations of acid-based methods.
