Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional batch enzymatic interesterification processes are used, then enzymatic treatment can be performed, but large amounts of enzymes and long reaction times are required
Solution Approach 1:
The patent employs a porous support material with controlled porosity to immobilize the enzyme. The porous structure provides a large surface area for enzyme attachment while allowing substrate diffusion, enabling the enzyme to be used at much lower concentrations (1% or less by weight) while maintaining high catalytic activity and achieving complete interesterification in 10 hours or less
Solution Approach 2:
The porous support material acts as an intermediary carrier that immobilizes the enzyme, allowing it to function effectively at low concentrations. The support material mediates between the enzyme and substrate, facilitating efficient catalysis while enabling easy separation of the enzyme from the reaction mixture
2Productivity
If chemical interesterification processes are used, then reaction speed is fast, but contaminants and by-products are generated requiring additional processing steps
Solution Approach 1:
The patent replaces chemical catalysts with an enzymatic catalyst immobilized on a porous support. This substitution eliminates the generation of harmful chemical by-products and contaminants associated with chemical interesterification, while the enzyme maintains high catalytic efficiency. The immobilized enzyme can be easily separated from the reaction mixture, eliminating the need for additional processing steps to remove contaminants
