Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plant-based meat substitutes lack the texture, mouthfeel, and chewing experience of real meat due to the absence of connective tissue components, making them less satisfying for consumers.
Innovation Solution
A method of preparing connective tissue analogs using a hydrocolloid base and dietary fiber additives, which are combined to form a hydrated gel, then dehydrated to create a non-covalently cross-linked polymer network, mimicking the mechanical properties of animal connective tissues, and can be incorporated into plant-based meat compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If plant-based meat substitutes are made by extruding plant materials, then they can be produced efficiently, but they lack the texture and mouthfeel of real meat due to absence of connective tissue components
Solution Approach 1:
The patent combines plant-based proteins with hydrocolloids (such as carrageenan, guar gum, xanthan gum) to create a composite material system that mimics the mechanical properties of animal connective tissue. This composite approach allows the product to achieve meat-like texture and elasticity without using animal-derived ingredients, resolving the contradiction between plant-based composition and authentic texture.
Solution Approach 2:
The patent employs high-pressure processing (HPP) to fundamentally change the physical and chemical parameters of the plant-based ingredients. By applying pressures of 100-1000 MPa, the treatment induces protein denaturation, starch gelatinization, and hydrocolloid gel formation, transforming the raw material properties to achieve connective tissue-like characteristics while maintaining production efficiency.
2Shape
If connective tissue analogs are produced using spun protein fibers and extrusion processes, then they can provide some structural similarity, but the methods are tedious, hard to scale up, and do not fully recapitulate the desirable texture
Solution Approach 1:
The patent extracts and isolates the essential functional components needed to mimic connective tissue - specifically hydrocolloids and plant proteins - while eliminating the need for complex extrusion and spinning equipment. By focusing on these key ingredients and using high-pressure processing instead of mechanical extrusion, the method achieves comparable structural similarity with much simpler manufacturing operations that are easily scalable.
3Ease of manufacture
If plant-based meat substitutes use homogeneous compositions, then they are easy to manufacture, but they do not convincingly reproduce the texture, mouthfeel, and chewing experience of real animal meat
Solution Approach 1:
The patent creates local quality variations within the homogeneous plant-based matrix by incorporating hydrocolloid-gel networks and protein aggregates at specific locations and concentrations. This allows different regions of the product to exhibit varied mechanical properties - some areas providing elasticity, others providing firmness - thereby reproducing the complex mouthfeel and chewing experience of real meat while maintaining overall manufacturing simplicity.

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 connective tissue analogs provide an authentic meat-like experience in terms of texture and mouthfeel when combined with plant-based meat bases, enhancing the consumer experience without relying on extrusion processes or animal-derived ingredients.
Implementation Method 1
combining ingredients comprising a hydrocolloid base and a dietary fiber additive to form a substantially homogenous mixture; hydrating the substantially homogenous mixture to form a hydrated gel
Implementation Method 2
