Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If plant protein-containing liquid composition is treated with protein deamidase alone, then protein solubility is improved, but digestibility and mineral solubility remain insufficient
Solution Approach 1:
The patent combines protein deamidase treatment with cellulase treatment in a sequential processing method. The protein deamidase modifies protein structure to improve solubility, while the subsequent cellulase treatment breaks down cellulose matrices to further enhance digestibility and mineral solubility. This merging of two enzymatic treatments resolves the contradiction by achieving all three targets simultaneously.
Solution Approach 2:
The protein deamidase treatment is performed as a preliminary step before cellulase treatment. This preliminary action of deamidation modifies the protein structure in advance, making it more soluble and accessible, which then allows the subsequent cellulase treatment to more effectively improve digestibility and mineral solubility.
2Quantity of substance
If protein solubility is improved by treating with protein deamidase and protease, then solubility increases, but protein hydrolysis occurs which may affect food characteristics
Solution Approach 1:
The patent extracts or removes the protease treatment step from the processing sequence, retaining only protein deamidase and cellulase treatments. This extraction eliminates excessive protein hydrolysis that would degrade mouthfeel, while still achieving improved solubility through deamidation and enhanced digestibility through cellulose breakdown.
Solution Approach 2:
The patent changes the enzymatic treatment parameters by selecting specific enzymes (protein deamidase and cellulase) with specific activities and controlling their amounts and treatment conditions. This parameter optimization allows solubility improvement without excessive hydrolysis that would harm food characteristics.
3Adaptability or versatility
If plant milk is used as alternative to animal milk, then dietary restrictions are addressed, but protein content and nutrient absorption efficiency remain lower
Solution Approach 1:
The patent combines protein deamidase treatment with cellulase treatment to simultaneously improve protein solubility, digestibility, and mineral solubility in plant milk. This merged enzymatic approach increases the bioavailability and absorption efficiency of proteins and minerals, making plant milk a more nutritious alternative to animal milk while maintaining its dietary adaptability.
