Non-enzymatic high-shear extrusion for suspensible wheat protein
A thermo-mechanical extrusion process transforms wheat gluten into a suspensible protein ingredient for beverages without relying on enzymes. The resulting protein powder is non-lumping and rapidly wetting, with potential for industrial scalability.
Overview
This innovative solution leverages a thermo-mechanical extrusion process to transform vital wheat gluten into a suspensible protein ingredient suitable for beverage applications. The process focuses on non-enzymatic mechanisms, utilizing controlled high-shear extrusion under specific moisture and temperature conditions. This approach induces protein unfolding and network disruption, resulting in fine protein aggregates with enhanced dispersion properties. The end product is a non-lumping, rapidly wetting protein powder that remains stable in liquid matrices, addressing common challenges in beverage formulations.
Technical specifications
- Non-enzymatic dominant process: Primarily relies on shear and heat to achieve protein structural transformation, with optional enzymatic intervention for peptide size tuning.
- Extrusion configuration: Utilizes a twin-screw extruder to control moisture, temperature, and screw dynamics, ensuring optimal protein restructuring.
- End product characteristics: Delivers a protein powder with reduced elasticity, capable of stable suspension in beverages, preventing lumping and enhancing wetting.
- Scalability: Designed for integration into existing industrial extrusion platforms, ensuring feasibility for large-scale production.
Technology readiness level
This technology is currently at TRL 4, with ongoing lab-scale validation to optimize process parameters and product characteristics. Future plans include pilot-scale optimization and industrial translation to confirm scalability and process consistency, in collaboration with academic and industry partners.
