Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional detoxification methods are used to remove aflatoxins, then mycotoxin levels are reduced, but the protein content and bioactive peptide generation are compromised
Solution Approach 1:
The patent extracts and removes aflatoxins from peanut meal using adsorbent materials, separating the harmful mycotoxins from the valuable protein components. This allows the protein to be retained and further processed into bioactive peptides while the toxins are eliminated.
Solution Approach 2:
The detoxification process is performed as a preliminary step before enzymatic hydrolysis. By removing aflatoxins first, the substrate is prepared for subsequent protein extraction and peptide generation, ensuring that the final product meets safety standards while maximizing nutritional value.
2Reliability
If peanut meal is used for animal feed, then economic value is maintained, but nutritional potential for human consumption is limited
Solution Approach 1:
The patent changes the critical parameter of mycotoxin concentration to meet human food safety standards. By reducing aflatoxin levels through adsorption, the peanut meal transitions from animal feed grade to human food grade, enabling broader application and higher economic value.
Solution Approach 2:
The process creates a composite product combining detoxified peanut protein with generated bioactive peptides. This composite material has enhanced nutritional properties and functional characteristics suitable for human consumption, expanding beyond traditional animal feed applications.
3Productivity
If oil extraction is optimized for maximum oil yield, then oil production is maximized, but protein quality and functionality are compromised
Solution Approach 1:
Instead of stopping after oil extraction, the process continues with detoxification, protein isolation, and enzymatic hydrolysis. This continuous utilization of the press cake maximizes the value of all components, transforming what would be a discarded byproduct into high-value bioactive peptides.
Solution Approach 2:
The patent recovers valuable proteins and bioactive peptides from the press cake that would otherwise be discarded or used only as low-value animal feed. Through systematic processing, the harmful components are discarded while the beneficial proteins are recovered and upgraded.
