Recombinant Avian Ovalbumin for Egg-White Gelation Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for sustainable, non-animal-based sources of protein to meet the growing global food demand, as the majority of protein intake currently comes from animal-based sources.
Innovation Solution
Development of recombinant avian ovalbumins, specifically from pigeon, hamerkop, and collard flycatcher, which are expressed in yeast cells and can be used as egg-white substitutes in food products, providing equivalent or superior gelation properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If animal-based protein sources are used, then protein quality and availability are ensured, but sustainability and ethical concerns deteriorate
Solution Approach 1:
The patent creates recombinant copies of avian ovalbumin proteins using synthetic biology. The amino acid sequences of egg white proteins are replicated in microbial hosts (yeast or bacteria), producing identical or highly similar protein structures without requiring actual eggs or animals. This copying approach maintains the functional properties of animal-based proteins while eliminating the need for animal farming and egg production.
Solution Approach 2:
The patent introduces microbial cells (yeast or bacteria) as intermediary organisms to produce the desired proteins. These microbial factories serve as mediators between genetic blueprints and functional protein products, enabling the synthesis of high-quality proteins without direct animal involvement. The intermediaries convert simple substrates into complex protein structures through recombinant expression systems.
2Object-affected harmful factors
If plant-based protein alternatives are developed, then sustainability improves, but functional properties (gelation, foaming) deteriorate
Solution Approach 1:
The patent modifies the molecular parameters of recombinant proteins to optimize their functional properties. By adjusting amino acid sequences, post-translational modifications, and protein folding conditions, the recombinant ovalbumins achieve gelation and foaming capabilities comparable to or exceeding natural egg whites. The microbial expression system allows precise control over protein structure and properties.
Solution Approach 2:
The patent creates composite protein formulations by combining recombinant ovalbumin with other proteins or functional ingredients. These composite materials synergistically enhance gelation strength, foaming stability, and water-holding capacity, achieving functional performance that surpasses individual plant-based alternatives while maintaining sustainability advantages.
3Reliability
If egg white protein is used in food products, then desired functional properties are achieved, but animal-derived ingredients and allergens are introduced
Solution Approach 1:
The patent extracts only the essential functional components of egg white (ovalbumin proteins) while leaving behind all harmful elements (allergens, cholesterol, bacteria, animal byproducts). Through selective recombinant expression of specific protein sequences, the invention isolates the beneficial gelation and foaming properties without co-introducing any animal-derived contaminants or allergenic epitopes.
Solution Approach 2:
The patent employs single-use microbial cells as temporary protein factories. These microbial hosts are grown, harvested for protein expression, and then discarded or repurposed, eliminating the need for persistent animal farming infrastructure. The microbial cells serve as disposable intermediaries that can be rapidly produced and eliminated without long-term environmental or ethical concerns.
