Vegan Egg White Structure Using Annealed Hydrocolloids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vegan food alternatives struggle to effectively emulate the taste, texture, and nutritional value of hard-boiled eggs, particularly in terms of scalability, shelf life, and compatibility with food allergies, due to challenges in replicating the complex protein structures and consistency of animal-based eggs.
Innovation Solution
A mycoprotein-free engineered food product is developed using an annealed hydrocolloidal mixture of nut milks, vegan thickeners, and fired salts to create a textured white layer and a yolk ball, which are combined to form a vegan hard-boiled egg alternative, ensuring nutritional benefits and appealing appearance and mouthfeel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mycoprotein-based formulations are used to emulate hard-boiled eggs, then the protein content and texture can be improved, but the product becomes unpalatable for users with fungal fermentation allergies and raises soy allergy concerns
Solution Approach 1:
The patent extracts and eliminates the problematic mycoprotein component from the formulation while retaining the desired functional properties through alternative plant-based protein sources, thereby removing the allergen issue for fungal fermentation-sensitive consumers
Solution Approach 2:
The patent employs a composite formulation combining multiple plant-based proteins (pea protein, rice protein, quinoa protein) with hydrocolloids and fats to create a synergistic mixture that replicates egg texture and nutrition without relying on mycoprotein or soy, thus achieving both texture improvement and allergen compatibility
2Shape
If coconut oil or vegetable oil emulsions are used to emulate the texture and color of cooked albumen, then the appearance and mouthfeel are improved, but the nutritional value deteriorates due to high cholesterol content in coconut oil and diminished shelf life
Solution Approach 1:
The patent modifies the fat component parameters by replacing coconut oil with a blend of plant-based oils (canola oil, olive oil, flaxseed oil) that have more favorable nutritional profiles including lower saturated fat and no cholesterol, while adjusting the formulation to maintain the desired creamy texture and color properties
Solution Approach 2:
The patent applies different functional ingredients to different components: pea protein and hydrocolloids for the white layer to achieve firmness, while the yolk uses a different combination including rice protein and specific fats to achieve creaminess, allowing each part to have optimized local properties for both appearance and nutrition
3Ease of operation
If soy compounds are used to approximate the texture and color of cooked albumen, then the mouthfeel is improved, but the product becomes unsuitable for users with soy allergies
Solution Approach 1:
The patent explicitly removes soy compounds from the formulation and replaces them with alternative plant-based proteins such as pea protein, rice protein, and quinoa protein that can provide similar functional properties without triggering soy allergies
4Ease of manufacture
If traditional vegan egg substitutes are developed to replicate egg properties, then the taste and appearance can be improved, but the scalability and shelf life remain insufficient for legitimate alternative status
Solution Approach 1:
The patent optimizes formulation parameters including protein concentration, hydrocolloid ratios, and fat content to achieve a product with extended shelf life and improved structural stability that maintains scalability for industrial production while preserving acceptable taste and appearance properties
Solution Approach 2:
The patent incorporates pre-cooked and pre-processed plant-based protein ingredients that have been prepared in advance to ensure consistent performance, extended shelf life, and scalability for mass production, eliminating the need for complex processing steps during final product manufacturing
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a scalable, allergen-friendly vegan hard-boiled egg alternative with improved shelf life and nutritional benefits, effectively replicating the taste and texture of traditional hard-boiled eggs while avoiding mycoprotein and soy, thus addressing the limitations of existing vegan egg substitutes.
Implementation Method 1
combining one or more nut milks, a vegan thickener, a second fired salt and water to form a second mixture, heating the second mixture to a boil
Implementation Method 2
adding the second mixture to the mold tray to cool to an annealing temperature
Implementation Method 3
freezing a volume of the first mixture to form a yolk ball
Implementation Method 4
mixing the first mixture to diffuse the vegan colorant
