Plant-Based Protein Extrudate Texture via High-Moisture Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mimicking the texture and flavor of meat using plant-based protein sources is challenging, especially when avoiding gluten and soy proteins, which are typically used to create fibrous textures due to their specific chemical compositions.
Innovation Solution
The use of a high-moisture extrusion cooking (HMEC) process to produce plant-based products with an anisotropically fibrous meat-like texture, involving a dry blend of at least two plant-based protein sources, heating and extruding under high moisture, high temperature, and high shear conditions, and cooling under laminar flow to form an extrudate with specific strain-force-max tension and hardness ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If gluten and soy proteins are used to create fibrous textures, then the meat-like texture is improved, but the product contains allergens and restricted ingredients
Solution Approach 1:
The patent extracts and removes gluten and soy proteins from the formulation, replacing them with alternative plant-based proteins (pea, rice, potato, corn) that can achieve similar textural properties without the allergenic concerns. This is accomplished through careful selection and combination of alternative protein sources that provide the necessary structural characteristics.
Solution Approach 2:
The patent employs composite materials by combining multiple plant-based protein sources (pea, rice, potato, corn proteins) to create a synergistic formulation that achieves meat-like fibrous texture without relying on gluten or soy. The composite approach allows each protein source to contribute different functional properties that collectively replicate the desired texture.
2Object-affected harmful factors
If plant-based protein sources are used instead of gluten and soy, then allergen-free products are achieved, but the fibrous texture formation becomes difficult
Solution Approach 1:
The patent applies parameter changes by optimizing processing conditions (extrusion temperature, moisture content, shear rate, and cooking time) to enable fibrous texture formation from alternative plant proteins. By adjusting these parameters, the formulation achieves proper protein denaturation, aggregation, and fiber alignment without requiring gluten or soy proteins.
Solution Approach 2:
The patent achieves universality by developing a multi-functional plant-based protein system that can simultaneously provide nutritional value, structural integrity, and meat-like texture without relying on specific restricted proteins. The formulation works across different processing conditions and can be adapted to various product types while maintaining the allergen-free advantage.
3Shape
If high-moisture extrusion cooking is used, then meat-like texture is achieved, but energy consumption increases
Solution Approach 1:
The patent utilizes phase transitions during the extrusion cooking process, where controlled moisture addition and temperature elevation cause protein denaturation, gelatinization, and fiber formation. The process leverages the phase change from dispersed protein to organized fibrous structure, achieving meat-like texture through controlled thermal and mechanical treatment that optimizes energy utilization.
