Solution Overview

Problem

Plant-based burgers lack the binding properties and texture of traditional meat patties, making them less flavorful and less enjoyable to eat, as they often rely on non-natural ingredients like methylcellulose for cohesion.

Innovation Solution

A chitosan-based thermogellable binding mixture is used, comprising chitosan, an acid source, and a base source, which is blended with textured vegetable protein to create a thermogellable composition that mimics the binding and texture of meat patties, providing a natural alternative to methylcellulose.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If methylcellulose is used as a binding agent in plant-based burgers, then binding cohesiveness and texture are improved, but the product can no longer claim to be made with natural ingredients

Engineering Contradiction:
Improvebinding cohesivenessVSAvoidnon-natural ingredient status
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent replaces synthetic methylcellulose with a natural alternative binding mixture based on soy protein isolate, starch, and modified food starch. This mixture provides equivalent binding cohesiveness while maintaining natural ingredient status, allowing the product to meet both functional requirements and natural labeling claims

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The invention uses a composite binding mixture combining multiple natural ingredients (soy protein isolate, starch, modified food starch) to achieve the binding properties previously only available from synthetic methylcellulose. This composite approach allows the formulation to match the functional performance of synthetic binders while maintaining natural ingredient composition

Inventive Principle:
Principle #40Composite materials

2Shape

If texturized vegetable protein is used to provide texture in plant-based burgers, then protein content and textural structure are improved, but the pieces lack natural stickiness and require additional binding agents

Engineering Contradiction:
Improvetextural structureVSAvoidbinding properties
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The patent combines texturized vegetable protein with a specially formulated binding mixture containing soy protein isolate, starch, and modified food starch. This combination provides both the textural structure of TVP and the binding cohesiveness needed to form intact patties, eliminating the need for separate synthetic binding agents

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention modifies the binding properties of the vegetable protein pieces by incorporating a binding mixture with specific compositional parameters (soy protein isolate, starch, modified food starch in defined ratios). This formulation change enables the pieces to achieve adequate binding cohesiveness while maintaining their inherent textural characteristics

Inventive Principle:
Principle #35Parameter changes

3Strength

If ground meat is used in traditional hamburgers, then binding cohesiveness and juiciness are achieved through fat and soluble proteins, but plant-based alternatives cannot replicate these properties

Engineering Contradiction:
Improvebinding cohesivenessVSAvoidmeat-like texture
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The patent formulates a binding mixture with specific compositional parameters (soy protein isolate, starch, modified food starch, salt, water) that replicates the binding and juiciness properties of ground meat. This controlled parameter approach allows plant-based patties to achieve meat-like texture and binding cohesiveness without using actual meat ingredients

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The invention creates a composite formulation combining texturized vegetable protein with a multi-component binding mixture that mimics the functional properties of ground meat. This composite structure provides binding cohesiveness, juiciness, and texture similar to traditional meat hamburgers while maintaining a plant-based composition

Inventive Principle:
Principle #40Composite materials
