Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If phospholipid is decomposed using phospholipase A in organic solvent, then enzymolysis reaction rate is improved, but the product cannot be used for food applications and requires solvent removal
Solution Approach 1:
The invention changes the solvent parameter from organic solvent to polyhydric alcohol (such as glycerin), which maintains high enzymolysis reaction rates while being safe for food applications. This parameter substitution resolves the contradiction by finding an alternative solvent that satisfies both productivity and safety requirements
Solution Approach 2:
The invention uses polyhydric alcohol as a replacement solvent that does not require removal, effectively treating the solvent as a final component of the product rather than a temporary medium requiring elimination. This approach eliminates the harmful factor of organic solvent presence while maintaining reaction efficiency
2Object-affected harmful factors
If phospholipid is decomposed in oil-in-water emulsion without organic solvent, then food application safety is improved, but enzymolysis reaction rate becomes slower and large amount of energy is required for water removal
Solution Approach 1:
The invention changes the dispersion medium parameter from water-based emulsion to polyhydric alcohol-based system. This parameter change simultaneously improves enzymolysis reaction rate while maintaining food safety and eliminating the need for energy-intensive water removal processes
Solution Approach 2:
The invention introduces polyhydric alcohol as an intermediary substance that facilitates the enzymolysis reaction more effectively than water-based systems. The polyhydric alcohol acts as a superior medium that enhances enzyme activity and reaction kinetics while being safe for food applications
3Adaptability or versatility
If phospholipid is decomposed in polyhydric alcohol-based mixture with controlled ratios, then self-emulsifying properties are achieved, but requires precise control of mixing ratios
Solution Approach 1:
The invention establishes specific parameter ranges for mixing ratios (phospholipid: 0.07-0.5 times total lipid, polyhydric alcohol: 0.4-3.0 times water content) that enable self-emulsifying properties. By defining these parameter ranges, the invention balances the need for precise control with the achievement of desired functional properties
