Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for extracting active ingredients from natural products, such as caviar, face challenges including denaturation due to high temperatures, contamination by oxygen, and the presence of impurities, especially in hot water extraction and organic solvent-based methods, which affect the quality and purity of the extracts.
Innovation Solution
A cosmetic composition utilizing subcritical water extract of plasma-treated caviar, where low temperature/atmospheric-pressure plasma is used to treat caviar, followed by subcritical water extraction, maintaining the integrity and purity of the active ingredients, thereby enhancing their anti-aging and anti-wrinkle properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hot water extraction is used to extract active ingredients from caviar, then extraction efficiency is improved, but the substance is denatured by heat and extract quality deteriorates
Solution Approach 1:
The patent changes the extraction parameters from high-temperature hot water extraction to subcritical water extraction at lower temperatures (typically 40-100°C), which prevents thermal denaturation of the active ingredients while maintaining adequate extraction efficiency. This parameter modification resolves the contradiction between extraction efficiency and extract quality.
2Productivity
If hot water extraction is used, then extraction efficiency is improved, but inevitable contact with oxygen during the process causes contamination
Solution Approach 1:
The patent employs subcritical water extraction which can be performed under controlled atmospheric conditions, reducing exposure to oxygen and other contaminants compared to traditional hot water extraction methods. The lower temperature process allows for better control over oxidation reactions, thereby minimizing oxygen contamination while maintaining extraction efficiency.
3Productivity
If organic solvent extraction is used, then extraction of natural products is effective, but impurities are mixed in and residual solvent removal is required
Solution Approach 1:
The patent uses water as the extraction solvent instead of organic solvents. Water is inexpensive, non-toxic, and does not require complex removal processes. This substitution eliminates the problems of impurity mixing and residual solvent removal while maintaining effective extraction of caviar active ingredients, thereby improving both purity and process simplicity.
