Oil Composition Oxidation Inhibition via Self-Emulsifying Surfactant
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods fail to effectively inhibit the oxidation of polyunsaturated fatty acids, particularly ω3 fatty acids, which are prone to rapid oxidation, leading to quality deterioration and health concerns when used in food and cosmetics.
Innovation Solution
An oil composition is developed containing an ionic surfactant and a polyhydric alcohol, where the lightness value difference before and after dilution with water is positive, creating a self-emulsifying property that inhibits oxidation by preventing contact with oxidation-promoting factors, thereby extending the oxidation induction period.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If polyunsaturated fatty acid is used for health benefits, then physiological activity and health enhancement are improved, but oxidation rate increases exceptionally rapidly
Solution Approach 1:
The patent applies preliminary action by adding specific antioxidants (tocopherol at 0.01-1.0 wt% and ascorbyl palmitate at 0.01-1.0 wt%) to the oil composition before use. These antioxidants are pre-introduced to prevent oxidation from occurring, addressing the rapid oxidation issue of polyunsaturated fatty acids before it can compromise health benefits or quality
Solution Approach 2:
The patent uses a composite antioxidant system combining tocopherol (a phenolic antioxidant) and ascorbyl palmitate (a water-soluble antioxidant). This composite approach creates synergistic protection where tocopherol donates hydrogen atoms to break oxidation chains while ascorbyl palmitate regenerates tocopherol, extending the oxidation induction period while maintaining the health benefits of ω3 fatty acids
2Reliability
If natural antioxidative substance is added to inhibit oxidation, then safety is improved, but sufficient oxidation inhibition effect is not obtained for polyunsaturated fatty acid
Solution Approach 1:
The patent optimizes the concentration parameters of antioxidants, specifically using tocopherol at 0.01-1.0 wt% and ascorbyl palmitate at 0.01-1.0 wt%. This precise parameter control ensures sufficient oxidation inhibition for polyunsaturated fatty acids while maintaining safety. The dual-antioxidant system at these optimized concentrations provides synergistic protection that single antioxidants cannot achieve alone
3Object-affected harmful factors
If synthetic antioxidant agent is used to inhibit oxidation, then oxidation inhibition effect is improved, but safety concerns increase
Solution Approach 1:
The patent replaces long-term used synthetic antioxidants (like BHA and BHT) with natural antioxidants tocopherol and ascorbyl palmitate. While natural antioxidants may have shorter individual lifespans, their regenerative capability through synergistic interaction extends their effective protection period. This substitution eliminates safety concerns associated with synthetic antioxidants while maintaining adequate oxidation inhibition
