Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercially available plant-based cheese products do not exhibit melting and stretching characteristics similar to dairy-based cheeses, have a dull appearance, and often lack nutritional protein content comparable to dairy-based cheeses, leading to consumer dissatisfaction.
Innovation Solution
A plant-based cheese product formulation comprising 10-25 wt% plant-based protein, at least 65 wt% amylopectin waxy starch, and fat, which stabilizes the product matrix and maintains small fat droplets, enabling desirable melt and stretch characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If starch-based gel is used in plant-based cheese products, then the product can be manufactured with basic structure, but the product does not exhibit melting and stretching characteristics expected of dairy-based cheeses
Solution Approach 1:
The patent uses a composite material system combining plant-based proteins (soy, pea, or rice protein) with starch-based gels and fat. This composite formulation allows the product to achieve both manufacturability and desirable melting/stretching characteristics by leveraging the complementary properties of each component: proteins provide structure and protein content, starch provides gelation and texture, and fat provides richness and melting behavior.
Solution Approach 2:
The patent modifies key parameters including protein content (increased to 10-25 wt%), starch type (waxy or native starch), fat content (10-30 wt%), and processing conditions (temperature, pH, mixing speed). These parameter changes enable the product to transition from a simple gel structure to a complex network that exhibits dairy-like melting and stretching properties while maintaining manufacturability.
2Quantity of substance
If higher amounts of protein are included in plant-based cheese products, then the nutritional content becomes comparable to dairy-based cheeses, but significant manufacturing challenges arise and flavor, textural, and structural properties are adversely impacted
Solution Approach 1:
The patent optimizes the protein content parameter to a specific range of 10-25 wt%, which is high enough to be nutritionally comparable to dairy cheeses but not so high as to cause manufacturing problems. It also optimizes other parameters including fat content (10-30 wt%), starch type, and processing conditions to balance nutritional content with manufacturability and product quality.
Solution Approach 2:
The patent creates a composite system where plant-based proteins are combined with starch and fat in specific proportions. This composite approach allows the protein to fulfill its nutritional function while the starch and fat components modulate the manufacturing behavior, flavor, texture, and structural properties, preventing the adverse effects that would occur with protein alone.
3Ease of manufacture
If starch-based gel is used in plant-based cheese products, then the product can be produced with basic structure, but the product has a dull appearance rather than the shiny appearance typical of dairy-based processed cheese
Solution Approach 1:
The patent employs a composite formulation where fat plays a crucial role in enhancing the appearance. The fat content (10-30 wt%) and its distribution within the protein-starch matrix contribute to the shiny appearance characteristic of dairy processed cheese. The interaction between fat, protein, and starch creates a heterogeneous structure that reflects light differently, producing the desired shininess.
Solution Approach 2:
The patent modifies parameters including fat content, protein-to-fat ratio, starch type, and processing temperature to optimize the appearance. These parameter changes affect the microstructure of the product, creating a smoother surface and better light reflection that results in the characteristic shiny appearance of quality processed cheese.
4Ease of manufacture
If typical plant-based cheese products are made with low protein content, then manufacturing is easier and texture is better, but the nutritional content is not comparable to dairy-based cheeses
Solution Approach 1:
The patent changes the protein content parameter from typical low levels to a optimized range of 10-25 wt%. This parameter change achieves high nutritional content while maintaining manufacturability by simultaneously adjusting other critical parameters including fat content (10-30 wt%), starch type, and processing conditions to prevent manufacturing difficulties.
