Plant-Based Meat Replica Texture and Color Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant-based meat substitutes fail to replicate the texture, flavor, and sensory experience of cooked meat effectively, particularly in terms of fibrousness, heterogeneity, and red-to-brown color transition during cooking, leading to off flavors and limited consumer appeal.
Innovation Solution
Development of plant-based meat replicas that incorporate specific proteins that gel and denature at temperatures similar to those in meat, along with heme-containing proteins and flavoring agents, to mimic the texture and flavor of cooked meat, including the use of carbohydrate-based gels and binding agents to enhance texture and juiciness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plant-based meat substitutes are made from extruded soy/grain mixtures, then they can be produced with simple ingredients, but they fail to replicate the fibrousness, heterogeneity in texture, and sensory experience of cooked meat
Solution Approach 1:
The patent uses composite materials by combining plant-based proteins with heme-containing proteins (such as soybean hemoglobin or recombinant heme proteins) and carbohydrate-based gels. This composite approach allows the product to achieve both the desired meat-like texture and color transformation while maintaining plant-based composition. The heme-containing proteins specifically contribute to the red-to-brown color transition during cooking, while the protein matrix provides the fibrous texture.
Solution Approach 2:
The patent applies parameter changes by carefully controlling the denaturation and gelling temperatures of the proteins used. The heme-containing proteins and plant proteins are selected and processed to undergo phase transitions at temperatures that mimic natural meat cooking behavior. This allows the replica to transform from a raw state with red color to a cooked state with brown color, replicating the sensory experience of cooking meat.
2Ease of operation
If artificial flavors and aromas are pre-incorporated into pre-cooked products, then they can be conveniently prepared, but they fail to replicate the natural aromas and flavors associated with cooking meat and may have off flavors
Solution Approach 1:
The patent applies preliminary action by pre-incorporating flavoring agents and heme-containing proteins into the product matrix during manufacturing, so that the natural meat-like flavors and aromas are already present. This eliminates the need for additional cooking or flavor addition steps by the consumer, while avoiding the need for strong artificial flavorings. The heme-containing proteins themselves contribute to the natural beefy flavor, reducing reliance on artificial additives.
3Manufacturing precision
If proteins are selected based on their gelling and denaturation temperatures to replicate meat behavior during cooking, then the texture and color transition can be improved, but the product complexity increases
Solution Approach 1:
The patent uses parameter changes by selecting heme-containing proteins and plant proteins with specific denaturation temperatures that match the cooking profile of natural meat. The heme-containing proteins (such as soybean hemoglobin) are chosen because they undergo color transformation at temperatures similar to meat cooking (from red in raw state to brown in cooked state). This temperature-based parameter control allows precise replication of meat-like sensory changes without requiring complex processing equipment.
