Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for extracting chitin from seafood waste are inefficient and environmentally harmful, often requiring harsh chemicals that lead to waste effluents and high water consumption.
Innovation Solution
A ternary deep eutectic solvent (TDES) system comprising a hydrogen bond acceptor (HBA), a polyol-based hydrogen bond donor (HBD), and an organic acid HBD is used to extract high-purity chitin from seafood waste, with adjustable molecular weight and viscosity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional methods are used to extract chitin from seafood waste, then chitin can be recovered, but harsh chemicals are required leading to environmental harm and high water consumption
Solution Approach 1:
The patent changes the chemical parameters of the extraction system by using a ternary deep eutectic solvent system composed of choline chloride, lactic acid, and glycerol in specific molar ratios. This parameter change allows for effective chitin extraction without harsh chemicals, reducing environmental harm while maintaining extraction efficiency through the unique solvent properties of the TDES system
Solution Approach 2:
The patent employs a composite solvent system combining three components (choline chloride, lactic acid, and glycerol) to create a ternary deep eutectic solvent. This composite material approach enables synergistic effects where the combination of components provides enhanced extraction capability while being environmentally friendly, resolving the contradiction between efficiency and environmental harm
2Loss of substance
If conventional extraction methods are used, then chitin can be extracted, but high water consumption is required
Solution Approach 1:
The patent replaces water-based mechanical extraction systems with a chemical solvent system (ternary deep eutectic solvent). This substitution eliminates the need for large volumes of water while maintaining effective chitin extraction through the solvent's chemical interactions with chitin molecules, thereby reducing water consumption without sacrificing extraction capability
3Manufacturing precision
If the TDES system is used to extract chitin, then high purity and tunable molecular weight are achieved, but the system complexity increases
Solution Approach 1:
The patent achieves molecular weight control by adjusting the molar ratios of the TDES components (choline chloride, lactic acid, and glycerol). By changing these parameters, the solvent system can be tuned to extract chitin with specific molecular weights, enabling precise control over product properties without requiring complex equipment or multiple processing stages
