Plant-Based Meat Substitute Composition Using Leghemoglobin and Cross-Linking Enzymes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current plant-based meat substitutes fail to accurately replicate the taste, texture, and cooking experience of meat products, limiting their appeal to a niche vegetarian or vegan market and failing to convert meat consumers due to homogenous texture and lack of authentic cooking and flavor replication.
Innovation Solution
Development of a meat substitute composition with high isolated and purified protein content, specifically mimicking the color, taste, and texture of animal-derived meats, using proteins such as leghemoglobin and myoglobin, and incorporating iron-containing proteins to mimic the color transition during cooking, along with plant-based fats and cross-linking enzymes to create gels and fibers that resemble muscle and fat tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If plant-based meat substitutes use extruded soy/grain mixtures, then production cost is reduced, but texture and mouthfeel become more homogenous and fail to replicate meat characteristics
Solution Approach 1:
The patent combines multiple plant proteins (soy protein, pea protein, wheat protein) with specific ratios and structures to create a composite material that replicates meat texture. This involves using extruded soy protein granules mixed with pea protein isolate and wheat protein, creating a multi-component system that achieves both cost-effectiveness and authentic meat-like mouthfeel through the synergistic interaction of different protein structures
Solution Approach 2:
The patent creates different local textures within the meat substitute by incorporating extruded soy protein granules that maintain their distinct granular structure amidst the protein matrix. This local granularity replicates the heterogenous texture of real meat, contrasting with the uniform homogenous texture of conventional extruded products, while still using cost-effective plant-based ingredients
2Ease of operation
If meat substitutes are sold pre-cooked with artificial flavors, then convenience is improved, but authentic cooking experience and aromas are lost
Solution Approach 1:
The patent prepares the meat substitute with pre-formed protein structures and incorporates natural flavor precursors during manufacturing, but leaves the final cooking process to the consumer. This preliminary preparation ensures the product has the correct texture foundation while allowing authentic meat-like aromas and flavors to develop during home cooking, combining convenience with culinary authenticity
Solution Approach 2:
The patent formulates the meat substitute with specific moisture content and protein structure that enable it to undergo desirable textural and flavor changes during cooking. The product is designed to absorb fats and develop savory flavors when cooked, replicating the parameter changes that occur in real meat during cooking, thereby providing an authentic cooking experience
3Quantity of substance
If animal farming is practiced on large scale, then protein production is increased, but environmental impact and water pollution are significantly worsened
Solution Approach 1:
The patent creates plant-based copies of animal proteins that replicate the functional and sensory properties of meat without requiring animal farming. By using isolated plant proteins formulated to mimic muscle fiber structure and cooking behavior, the invention produces equivalent protein quantities while eliminating the environmental harm associated with livestock production
Solution Approach 2:
The patent changes the fundamental production parameters from animal-based to plant-based protein synthesis. This involves shifting from livestock rearing to plant cultivation and protein isolation, fundamentally altering the production system to achieve the same protein output with dramatically reduced environmental impact, water consumption, and land use
