Cheese-Based Fibrous Product Formation with Hydrocolloid Cross-Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processes for preparing fibrous meat substitute products struggle to achieve high moisture content, juicy mouthfeel, and desirable texture while maintaining excellent taste properties, often relying on cheese curd and requiring cheese factory integration, which limits flexibility and inclusivity for lactose-intolerant consumers.
Innovation Solution
A process using cheese as the primary milk protein material, mixed with a high amount of water, a moisture binder, and a calcium-complex forming agent, followed by the addition of a hydrocolloid and metal cation solution to form a fibrous product with a moisture content of at least 65% and a pH of 6.4 to 7.5, allowing for improved processability and lactose-free options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If cheese curd is used as the starting material and traditional processes are followed, then the fibrous product can be prepared, but the moisture content is limited to below 60% and the process requires integration with cheese factory operations
Solution Approach 1:
The patent changes key process parameters including raising the pH to 6.4-7.5 (above traditional ranges), increasing temperature to 80-95°C, and using cheese instead of cheese curd as the starting material. These parameter changes enable higher moisture content (at least 65%) while maintaining fiber formation and eliminating the need for cheese factory integration.
Solution Approach 2:
The patent extracts the fiber formation process from the cheese manufacturing context by using cheese as a starting material rather than cheese curd. This separation allows the fibrous product preparation to be performed independently without requiring integration with cheese factory operations, thereby improving process flexibility.
2Quantity of substance
If more water is added to increase moisture content, then juicy mouthfeel is improved, but the fiber structure and texture may be compromised
Solution Approach 1:
The patent employs specific parameter changes including pH 6.4-7.5, temperature 80-95°C, and controlled addition of calcium-complex forming agents and metal cations. These optimized parameters enable the system to accommodate high water content (at least 65% moisture) while maintaining proper fiber structure and texture through controlled protein denaturation and cross-linking.
Solution Approach 2:
The patent creates a composite system combining cheese proteins, hydrocolloids, and metal cations that work synergistically. The hydrocolloids and metal cations form a network structure that traps and holds water, allowing high moisture content while maintaining fiber integrity and texture through the composite material architecture.
3Adaptability or versatility
If cheese curd is used as the starting material, then the process follows traditional methods, but the product contains lactose and requires cheese factory integration
Solution Approach 1:
The patent extracts the lactose component by using cheese instead of cheese curd as the starting material. Cheese has lower lactose content than cheese curd, and the subsequent processing steps further reduce lactose, making the final product suitable for lactose-intolerant consumers without requiring complex production facilities.
Solution Approach 2:
The patent changes the starting material from cheese curd to cheese and adjusts process parameters (pH 6.4-7.5, temperature 80-95°C) to achieve lactose reduction. These parameter changes simplify the production process by eliminating the need for cheese factory integration while improving dietary inclusivity for lactose-intolerant consumers.

AI summary
Process for the preparation of a fibrous product comprising protein and having a moisture content of at least 65% by weight by first preparing a homogenous mixture of protein material comprising cheese, a moisture binder material, a calcium-complex forming agent and water at a temperature between 70 and 90° C. under high shear with the pH of the homogenous mixture being from 6.4 to 7.5. The homogenous mixture has a water content of at least 75% by weight, whilst total protein content is from 5 to 20% by weight. Into this homogenous mixture is mixed a hydrocolloid which precipitates with metal cations, after which a solution of a metal cation with a valency of at least 2 is added in order to form the fibrous product. This fibrous product is then isolated and cooled. The fibrous product thus obtained is particularly suitable for use in preparing meat substitute products.
