Enzyme-assisted stabilization of acidified hybrid meat batters
This solution leverages protein-glutaminase and transglutaminase to enhance the stabilization of acidified hybrid meat batters, improving hydration, dispersion, and structural cohesiveness. It targets the soy-protein-centered hybrid meat model, optimizing processing conditions for better product quality.
Overview
The enzyme-assisted stabilization of acidified hybrid meat batters offers an innovative approach to enhancing the quality and processing of plant-protein-based meat products. Utilizing a dual-enzyme strategy with protein-glutaminase (PG) and transglutaminase (TG), this technology aims to improve the hydration, dispersion, and resistance to acid-induced aggregation in meat batters. The approach is particularly relevant to the soy-protein-centered hybrid meat model, where maintaining a homogeneous and processable batter during acidification is crucial. This method also supports stable structure formation during thermal processing, addressing key challenges in hybrid meat production.
Technical specifications
Key features:
- Protein-glutaminase (PG): Enhances protein functionality by modifying proteins prior to acidification, reducing rapid aggregation and improving hydration.
- Transglutaminase (TG): Promotes controlled protein network formation, aiding in post-heating cohesiveness and restructuring.
- Optimized processing conditions: Tailored enzyme sequence and treatment levels improve flowability and cohesive structure, reducing water/oil separation and denaturation.
This technology is applied within a soy-protein-centered hybrid meat system, aligning with partner-specific formulation composition, target pH range, and thermal restructuring conditions.
Technology readiness level
The current development stands at Technology Readiness Level 5. The three-phase validation process involves aligning on target product attributes, optimizing enzyme treatment, and assessing batter characteristics under relevant conditions. Partner input is sought for further validation and practical translation into product-relevant settings.
