Plant-Based Egg Substitute Using Crosslinked Hydrocolloid System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current egg substitutes either contain actual egg whites, posing pathogen risks, or lack essential culinary properties like binding and moisturizing, making them unsuitable for various applications, especially for vegan diets.
Innovation Solution
A substantially egg-less composition comprising a starch and/or lipid source, a protein source, and a hydrocolloid system with a crosslinking agent, which includes a mixture of lower- and higher-temperature gelling hydrocolloids, allowing for the creation of a crosslinked structure that emulates the properties of eggs in culinary applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If egg substitutes are made from real egg whites, then they provide good culinary properties, but they carry pathogen risks and are not suitable for vegan diets
Solution Approach 1:
The patent extracts and replicates only the functional properties of eggs (binding, leavening, moisturizing) using plant-based ingredients, while completely excluding the harmful pathogen-containing egg white material. This separation allows achieving culinary reliability without pathogen risk.
Solution Approach 2:
The invention uses composite plant-based materials including starch, protein, and hydrocolloid systems to replicate egg functions. This composite approach provides the necessary binding and leavening properties without using actual egg products, thereby eliminating pathogen risks while maintaining culinary reliability.
2Object-affected harmful factors
If powdered egg replacement products are made egg-free, then they eliminate pathogen risks, but they lack binding and moisturizing properties
Solution Approach 1:
The patent combines multiple plant-based components (starch, protein, hydrocolloids) into a composite system that collectively provides binding, leavening, and moisturizing properties. This composite approach compensates for the absence of actual egg materials while maintaining culinary functionality.
Solution Approach 2:
The invention modifies the chemical and physical parameters of plant-based ingredients through processing and formulation to achieve egg-like functional properties. The hydrocolloid system undergoes crosslinking upon liquid introduction to create gel structures that mimic egg's binding and moisturizing characteristics.
3Device complexity
If egg substitutes use a single hydrocolloid system, then the formulation is simple, but they cannot provide both lower- and higher-temperature gelling properties
Solution Approach 1:
The patent merges multiple hydrocolloid types with different gelling temperature characteristics into a single formulation. This combination allows the system to exhibit both lower-temperature and higher-temperature gelling properties, enabling versatility across different culinary applications while maintaining a unified product formulation.

AI summary
An egg substitute composition includes a substantially egg-less dry mixture that includes a starch and/or lipid source and/or a protein source, and a hydrocolloid system. The hydrocolloid system includes a mixture of hydrocolloids and a crosslinking agent. The crosslinking agent is adapted to crosslink the mixture of hydrocolloids upon the introduction of a liquid. The mixture of hydrocolloids includes a lower-temperature gelling hydrocolloid and a higher-temperature gelling hydrocolloid. The compositions may further include a liquid activator, which may be added to the dry mix to hydrate the composition, and enable use of the composition in any application typically calling for raw eggs, e.g., scrambled eggs, omelets, frittatas, etc. The compositions (in dry or hydrated form) may also be used as egg-substitutes in various different applications, such as in emulsions (e.g., mayonnaise), and baking mixes.
