Structured Protein Isolate Emulsions for Dairy-Like Stretch and Melt
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing plant-based food products struggle to replicate the stretchy and meltable characteristics of dairy products, often requiring high amounts of carbohydrates and denaturing proteins, which limits their functionality and nutritional profile.
Innovation Solution
The method involves forming structured protein isolates (SPIs) from plant sources without significant denaturation, combining them with lipids to create emulsions that exhibit dairy-like stretch and melt characteristics, and processing these isolates to form gels or fermented products, such as cheese analogs, while reducing carbohydrate content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional methods are used to produce plant-based food products, then the products can be manufactured, but they lack stretchy and meltable characteristics and require high amounts of carbohydrates
Solution Approach 1:
The patent changes the physical and chemical parameters of plant proteins through controlled processing conditions (temperature, pH, salt concentration) to induce structured aggregation that provides stretchy and meltable characteristics, eliminating the need for high carbohydrate content
Solution Approach 2:
The invention creates composite protein structures by combining multiple protein isolate units into structured aggregates with specific morphologies, forming a composite material system that exhibits dairy-like rheological properties without requiring carbohydrates
2Ease of manufacture
If conventional methods are used, then products can be produced, but they require denaturing proteins which limits functionality and nutritional profile
Solution Approach 1:
The patent employs controlled parameter changes in processing conditions (moderate temperatures, optimized pH levels, salt concentrations) to achieve protein aggregation and structured isolate formation without causing protein denaturation, thereby preserving protein functionality and nutritional value while enabling product manufacturing
Solution Approach 2:
The invention replaces mechanical denaturation methods with controlled chemical and physical parameter adjustments to achieve the desired product characteristics, substituting harsh mechanical processing with gentler, more controlled processing conditions that maintain protein integrity
