Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing imitation cheese struggle with achieving the right balance of gelling and melting properties, often requiring high protein content and resulting in reduced functionality due to residual sulfite levels in starches used.
Innovation Solution
A modified potato starch with specific carboxylation levels and viscosity profiles is developed through oxidation, allowing for the formation of thermal-reversible gels that can replace protein in imitation cheese, while minimizing sulfite levels to enhance product functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional starches are used to produce imitation cheese, then gelling and melting properties can be achieved, but residual sulfite levels reduce product functionality
Solution Approach 1:
The patent removes sulfite from the starch production process entirely, extracting the harmful substance from the system. The oxidation process uses alternative methods that do not introduce sulfite, eliminating the need for subsequent removal steps and ensuring no residual sulfite remains in the final product.
Solution Approach 2:
The patent changes the chemical parameters of the oxidation process by controlling the degree of oxidation (DS 0.03-0.08) and using alternative oxidizing agents or conditions that do not generate sulfite residues, thereby maintaining functionality while eliminating harmful substances.
2Strength
If high protein content is used in imitation cheese, then gelling properties are improved, but manufacturing cost and complexity increase
Solution Approach 1:
The patent modifies the starch parameters through controlled oxidation to achieve DS 0.03-0.08, which fundamentally changes the gelling properties of the starch. This allows the starch to provide adequate gelling strength at lower concentrations, reducing the need for high protein content and simplifying the manufacturing process.
Solution Approach 2:
The patent creates a composite functional system by modifying starch with specific oxidation levels to combine the gelling properties traditionally associated with high protein content with the cost-effectiveness and simplicity of starch-based systems.
3Manufacturing precision
If oxidation process is used to modify starch, then carboxylation levels and viscosity profiles are improved, but process time and complexity increase
Solution Approach 1:
The patent optimizes the oxidation process parameters including pH control (maintaining pH 10-12 during oxidation), temperature, and oxidant concentration to achieve the target DS range of 0.03-0.08 within a controlled time frame. By precisely controlling these parameters, the process achieves high precision in carboxylation level while minimizing unnecessary process time.
Solution Approach 2:
The patent implements monitoring and control mechanisms during the oxidation process to track the degree of carboxylation development, allowing real-time adjustments to maintain optimal conditions and achieve consistent DS 0.03-0.08 results efficiently.
