Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pea protein products suffer from low solubility and flavor issues, limiting their market acceptance, as they typically have a Nitrogen Solubility Index (NSI) below the industrial requirement of 88.0%.
Innovation Solution
A method involving high pressure homogenization of pea protein compositions at pressures between 15 MPa and 200 MPa, with a pH range of 7.2 to 10.0, followed by optional flashing and drying, significantly improves solubility by reducing particle diameter and altering the protein's secondary structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional processing methods are used for pea protein compositions, then the processing is simple and cost-effective, but the nitrogen solubility index remains below 88.0% which limits market acceptance
Solution Approach 1:
The patent applies parameter changes by subjecting pea protein composition to high pressure homogenization at pressures between 15-200 MPa, which fundamentally alters the physical state and structure of the protein particles. This parameter change (pressure application) transforms the insoluble or low-solubility pea protein into a high-solubility form achieving NSI ≥ 88.0%, while the processing remains relatively simple and can be integrated into existing production lines
2Reliability
If high pressure homogenization is applied to improve solubility, then the nitrogen solubility index increases to 88.0% or higher, but the equipment complexity and processing cost increase
Solution Approach 1:
By changing the pressure parameter to high levels (15-200 MPa) during homogenization, the patent achieves dramatic improvement in nitrogen solubility index to ≥ 88.0%. This parameter change enables the transformation of conventional low-solubility pea protein into a high-value product with excellent solubility properties
Solution Approach 2:
The high pressure homogenization is applied as a preliminary treatment to the pea protein composition before further processing or application. This preliminary action of disrupting protein structure at high pressure prepares the material for subsequent uses, ensuring high solubility is achieved upfront which simplifies downstream processing
