Solution Overview

Problem

Current protein-polysaccharide complexes have limitations in enhancing emulsifying and stabilizing properties, particularly in food, cosmetic, and pharmaceutical applications, where they often result in unstable products or require additional modifications to achieve optimal performance.

Innovation Solution

The development of hydrolysed protein-polysaccharide complexes through enzymatic hydrolysis of electrostatically bound protein-polysaccharide complexes, specifically using enzymes like fungal protease, bromelain, or acid protease, to achieve a degree of hydrolysis between 1 to 50%, which enhances their emulsifying and stabilizing capabilities without hindering protein-polysaccharide interactions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If protein-polysaccharide complexes are formed using conventional methods, then basic emulsifying properties are achieved, but emulsifying stability over time is insufficient

Engineering Contradiction:
Improveemulsifying stabilityVSAvoidstability over time
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent applies parameter changes by controlling the degree of hydrolysis of the protein component within a specific range (1-50%, preferably 5-30%). This hydrolysis modifies the protein's molecular weight, charge distribution, and conformation, thereby enhancing its emulsifying stability while maintaining protein-polysaccharide complex formation. The hydrolysis degree is controlled through enzyme selection, reaction time, and temperature parameters.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite material system by forming complexes between hydrolysed protein and polysaccharides. The composite structure combines the hydrophobic regions of hydrolysed protein with hydrophilic polysaccharide chains, generating synergistic effects that improve emulsifying stability beyond what either component could achieve alone. The electrostatic and hydrophobic interactions in the composite provide enhanced structural stability over time.

Inventive Principle:
Principle #40Composite materials

2Reliability

If the degree of hydrolysis is increased to improve emulsifying properties, then emulsifying capacity increases, but protein-polysaccharide interactions may be hindered

Engineering Contradiction:
Improveemulsifying capacityVSAvoidprotein-polysaccharide interactions
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent optimizes the hydrolysis degree parameter within a balanced range (1-50%, preferably 5-30%) to simultaneously achieve good emulsifying capacity and maintain protein-polysaccharide interactions. This parameter optimization ensures that sufficient peptide bonds are broken to create active emulsifying sites while preserving enough intact protein structure to maintain electrostatic and hydrophobic interactions with polysaccharides.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality changes through selective hydrolysis where only specific regions of the protein molecule are cleaved while other regions remain intact. This creates a heterogeneous structure with locally modified hydrophobicity and charge distribution, allowing different parts of the protein to simultaneously participate in emulsification and maintain complex formation with polysaccharides.

Inventive Principle:
Principle #3Local quality
