Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fish and shellfish feeds, particularly those containing plant proteins like soybean meal, suffer from poor digestibility and inadequate growth performance, necessitating the development of a protein digestibility enhancing agent to improve protein utilization and growth in fish and shellfish.
Innovation Solution
A protein digestibility enhancing agent comprising a reducing agent with an oxidation-reduction potential of 0.1 V to 0.6 V and a nonionic surfactant is used to cleave disulfide bonds in proteins, enhancing their digestibility, particularly in plant proteins, by synergistic action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If plant proteins are used as alternative protein sources in fish and shellfish feed, then feed cost is reduced and environmental sustainability is improved, but protein digestibility and fish growth performance deteriorate
Solution Approach 1:
The patent applies parameter changes by modifying the chemical structure of plant proteins through controlled hydrolysis to reduce molecular weight and improve digestibility. By adjusting hydrolysis conditions (time, temperature, enzyme type), the protein structure is transformed to enhance enzymatic breakdown while maintaining essential amino acid composition, thus resolving the contradiction between using plant proteins and achieving good digestibility
Solution Approach 2:
The patent creates composite feed formulations combining hydrolyzed plant proteins with specific additives including organic acids, enzymes, and binding agents. This composite approach improves protein digestibility and feed utilization while maintaining the cost benefits of plant-based ingredients, effectively addressing the contradiction between plant protein usage and growth performance
2Reliability
If plant proteins are used in feed, then feed sustainability is enhanced, but fish growth performance deteriorates due to poor protein digestibility
Solution Approach 1:
The patent transforms plant protein parameters through hydrolysis treatment, changing molecular weight distribution and structural configuration to improve digestibility. This enables sustainable plant-based feeds to achieve growth performance comparable to or exceeding traditional fish meal-based feeds
Solution Approach 2:
The patent applies local quality improvement by selectively modifying specific regions of plant protein molecules through targeted hydrolysis. This enhances digestibility in critical areas while preserving essential amino acid profiles and functional properties needed for fish growth and feed sustainability
