Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods do not efficiently extract and produce 3,5-dihydroxy-4-methoxybenzyl alcohol (DHMBA) as an antioxidant from shellfish meats of filter-feeding bivalves other than oysters.
Innovation Solution
The method involves putting shellfish meat of a bivalve other than an oyster into an extraction liquid and either heating or pressurizing the liquid to produce DHMBA from the shellfish meat liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional extraction methods are used on bivalves other than oysters, then extraction efficiency is low, but applying heating or pressurization increases energy consumption and process complexity
Solution Approach 1:
The patent applies parameter changes by heating the extraction liquid to 95°C or higher for 1 hour or more, or by pressurizing to 2 atmospheres or more. These parameter modifications enable efficient extraction of DHMBA from bivalve meats other than oysters, resolving the contradiction between extraction efficiency and energy consumption by establishing optimized processing conditions.
2Productivity
If heating or pressurization is applied to extract DHMBA, then extraction efficiency improves, but the device complexity and process difficulty increase
Solution Approach 1:
The patent simplifies the extraction process by modifying only two key parameters: temperature (heating to 95°C or higher) or pressure (pressurizing to 2 atmospheres or more). This approach maintains device simplicity while achieving high extraction efficiency, avoiding the need for complex multi-step processing systems.
3Quantity of substance
If DHMBA is extracted from bivalves other than oysters using conventional methods, then the process is simple, but the yield and effectiveness are insufficient
Solution Approach 1:
The patent achieves high DHMBA yield from various bivalve meats (scallops, clams, mussels, etc.) by applying specific parameter changes: heating to 95°C or higher for 1 hour or more, or pressurizing to 2 atmospheres or more. These modifications maintain process simplicity while dramatically improving extraction yield compared to conventional methods.
