Solution Overview

Problem

Conventional milk production raises concerns about animal welfare and environmental impact, and plant-based alternatives fail to replicate the flavor and nutritional profile of milk proteins with identical or similar functionalities.

Innovation Solution

Development of recombinant milk proteins with non-native post-translational modifications (PTMs) such as glycosylation, phosphorylation, methylation, and others, to create dairy substitutes that mimic native milk proteins.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional milk production via animal husbandry is used, then milk proteins with natural functionalities are obtained, but animal welfare concerns and environmental impact worsen

Engineering Contradiction:
Improvefunctional characteristics of milk proteinsVSAvoidanimal welfare and environmental impact
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent creates recombinant milk proteins that copy the structure and functionality of native milk proteins through genetic engineering. The recombinant proteins are designed to replicate the amino acid sequences and post-translational modifications of natural milk proteins, enabling them to perform identical functional roles without requiring animal husbandry.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent uses recombinant DNA technology as an intermediary to transfer the functional characteristics of native milk proteins into microbial or cellular expression systems. This intermediary approach allows the production of functionally equivalent proteins through controlled biological synthesis rather than traditional animal farming.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If plant-based alternatives are used to replace milk, then animal welfare concerns are addressed, but the ability to replicate flavor and nutritional profile of milk proteins deteriorates

Engineering Contradiction:
Improveanimal welfare concernsVSAvoidflavor and nutritional profile replication
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent employs precise control of post-translational modification parameters to achieve native-like protein characteristics. By adjusting glycosylation patterns, phosphorylation sites, and other PTM parameters during recombinant protein expression, the invention replicates the nuanced flavor and nutritional properties of natural milk proteins that plant-based alternatives cannot achieve.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates composite recombinant protein structures that combine multiple functional elements within a single protein molecule. These composite proteins integrate various post-translational modifications and amino acid sequences to reproduce the complex functional profile of native milk proteins, surpassing the capabilities of simple plant-based substitutes.

Inventive Principle:
Principle #40Composite materials

3Ease of manufacture

If recombinant milk proteins with non-native PTMs are produced, then production concerns are addressed, but the complexity of achieving identical functionalities to native proteins increases

Engineering Contradiction:
Improveproduction of milk protein alternativesVSAvoidachieving identical protein functionalities
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent incorporates preliminary design of post-translational modification sites into the recombinant protein constructs before expression. By pre-engineering specific glycosylation sites, phosphorylation residues, and other PTM locations into the protein sequence, the invention simplifies the manufacturing process while ensuring the proteins achieve their intended native-like functionalities.

Inventive Principle:
