TVP Amino Acid Composition for Meat-Like Texture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional alternative meats fail to replicate the texture attributes of real meat, such as juiciness and mouthfeel, despite the addition of blending materials like gluten, starch, and fiber, necessitating improved methods for producing textured vegetable protein (TVP) that can mimic meat-like texture.
Innovation Solution
Incorporating basic amino acids, such as arginine, histidine, and lysine, along with cysteine, into the composition for producing textured vegetable protein, and using a microbial fermentation process, chemical methods, or hydrolysis to enhance texture, combined with extrusion and quick freezing to create meat-like texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional blending materials such as gluten, starch, and fiber are added to defatted soybean flour and isolated soybean protein, then tissue cohesion and chewiness are improved, but juiciness and mouthfeel remain insufficient to match real meat
Solution Approach 1:
The patent changes the chemical composition parameters by introducing basic amino acids (arginine, histidine, lysine) and cysteine to the TVP formulation. These amino acids modify the protein structure and interaction properties, enabling improved juiciness and mouthfeel while maintaining tissue cohesion, thus resolving the contradiction between structural strength and sensory quality.
Solution Approach 2:
The patent creates a composite material system combining vegetable protein with specific amino acids (basic amino acids and cysteine). This composite approach allows the material to exhibit both the structural properties needed for tissue cohesion and the functional properties required for juiciness and mouthfeel, effectively resolving the contradiction between these opposing requirements.
2Adaptability or versatility
If various blending materials are added to improve texture attributes, then alternative meat becomes more viable, but the complexity of the composition increases
Solution Approach 1:
The patent extracts and isolates the key functional components (basic amino acids and cysteine) that are responsible for meat-like texture attributes. By identifying and using only these essential components rather than multiple blending materials, the formulation achieves meat-like texture while reducing overall composition complexity.
Solution Approach 2:
The patent simplifies the composition by changing the approach from using multiple macro-components (gluten, starch, fiber) to using specific amino acid components. This parameter change in the chemical composition reduces the number of ingredients needed while achieving the same or better texture attributes, thereby reducing composition complexity.
