Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meat production methods, including cultured and plant-based alternatives, face challenges such as high cost, safety concerns from genetically-modified cell lines, contamination risks, and the inability to accurately mimic the texture, color, and nutritional profile of meat, particularly the juiciness of whole muscle tissue.
Innovation Solution
The production of muscle-like nanofiber systems using centrifugal spinning technology, incorporating healthy oils, myoglobin, and polysaccharide-protein blends to create hierarchical structures that encapsulate oils and proteins, mimicking the texture, color, and nutritional content of meat.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cultured meat is produced using cell-based agriculture, then the nutritional value and texture of meat can be maintained, but the cost and safety risks increase
Solution Approach 1:
The patent extracts and eliminates the problematic elements of cultured meat production (genetically modified cell lines, complex culture media, expensive equipment) while retaining the desirable outcome (meat-like texture and nutrition). It replaces these with simple plant proteins and natural fibers that can be produced at low cost without safety concerns.
Solution Approach 2:
The patent uses inexpensive, readily available plant-based materials (soy protein, pea protein, wheat protein) and natural fibers (flax, hemp, cotton) instead of expensive cultured meat infrastructure. These materials are cheap, safe, and can be produced at scale without the high costs and safety risks associated with cell-based agriculture.
2Ease of manufacture
If plant-based meat alternatives are produced using extrusion technology, then the cost is reduced, but the texture and nutritional profile cannot accurately mimic meat
Solution Approach 1:
The patent segments the meat structure into individual fibers and fascicles, then reconstructs them using plant proteins and natural fibers. This segmentation allows precise control over texture at the micro-level while maintaining affordability through simple processing techniques, avoiding the need for complex extrusion machinery.
Solution Approach 2:
The patent creates composite materials by combining plant proteins (soy, pea, wheat) with natural fibers (flax, hemp, cotton) and fat sources. This composite approach achieves meat-like texture and nutritional profile at lower cost than cultured meat, while maintaining simplicity in the manufacturing process.
3Reliability
If traditional meat production is used, then the texture and nutritional value are maintained, but environmental sustainability deteriorates
Solution Approach 1:
The patent changes the fundamental parameters of meat production from animal-based to plant-based materials. By using plant proteins and natural fibers, it maintains nutritional value and texture while eliminating the environmental harms of animal farming, such as greenhouse gas emissions, land use, and water consumption.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The nanofiber systems provide a more environmentally friendly and safer meat substitute with improved texture, color, taste, and nutritional benefits, resembling the attributes of animal meat, addressing the limitations of current alternatives.
Implementation Method 1
The disclosure describes a method for producing muscle-like nanofibers using a centrifugal spinning system. The system includes a rotor that spins at high speed to generate centrifugal force, causing protein-fiber complexes to separate and organize into hierarchical structures.
Implementation Method 2
The disclosure describes the formation of hierarchical nanofiber structures with multiple levels of organization. The system creates primary fibers, secondary fascicles, and tertiary muscle-like bundles, where each level encapsulates the previous one, mimicking the architecture of real muscle tissue.
Data Source
AI summary
Methods for producing a meat substitute with plant-based fat contents are disclosed. The methods include the use of protein and/or polysaccharide polymer with fibrillar properties in combination with protein sources of essential amino acids such as plant-based protein. These polymers may be mixed together and then combined with an oil phase emulsion to produce a precursor emulsion. The precursor emulsion may then be processed into three-dimensional fiber structures that include muscle-like fibers with fat encapsulation of the proteins. A contemplated method for forming the fibers includes centrifugally spinning the precursor emulsion to form the fibers.
