A process involving enzyme treatment, pressure cooking, and optional acid hydrolysis followed by centrifugation and drying is used to produce a high-quality, insoluble protein composition with small particle size from poultry, enhancing amino acid profiles and reducing fat content.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If traditional animal meat sources are used to produce protein powders, then complete amino acid profiles are achieved, but large particle sizes and high fat content are produced

Engineering Contradiction:
Improveparticle sizeVSAvoidfat content
Core Design Contradiction:
Manufacturing precisionVSQuantity of substance

Solution Approach 1:

The patent applies segmentation by mechanically separating the meat into fine particles through controlled grinding and milling processes, dividing the protein matrix into small discrete particles while maintaining amino acid integrity. This mechanical segmentation achieves particle sizes suitable for beverage formulations while preserving the complete amino acid profile of the original meat source.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts and removes fat from the meat protein matrix through a series of processing steps including mechanical separation, centrifugation, and filtration. This extraction process isolates the protein component from the fat, achieving low fat content in the final protein powder while maintaining the complete amino acid profile through selective removal of non-protein components.

Inventive Principle:
Principle #2Taking out (Extraction)

2Quantity of substance

If plant protein sources are used, then small particle sizes are achieved, but incomplete amino acid profiles are produced

Engineering Contradiction:
Improveamino acid completenessVSAvoidparticle size
Core Design Contradiction:
Quantity of substanceVSManufacturing precision

Solution Approach 1:

The patent applies parameter changes by controlling the mechanical processing parameters (grinding intensity, milling speed, moisture content) to achieve optimal particle sizes while preserving the complete amino acid profile. By adjusting these parameters, the process produces fine particles comparable to plant-based proteins while maintaining the superior amino acid completeness of animal sources.

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If high pressure treatment is applied to hydrolyze meat proteins, then protein breakdown is achieved, but excessive hydrolysis and loss of protein quality occur

Engineering Contradiction:
Improveprotein hydrolysis controlVSAvoidprotein quality
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent applies partial action by implementing controlled, limited hydrolysis through mild pressure treatment and enzymatic processes rather than excessive hydrolysis. This partial breakdown of protein structures improves protein quality and digestibility while avoiding the negative effects of over-hydrolysis, such as loss of amino acid integrity and protein denaturation.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent uses enzymes as intermediary agents to control and regulate protein hydrolysis. These enzymatic mediators provide specific, controlled breakdown of protein bonds under mild conditions, achieving optimal protein quality without the excessive hydrolysis that would occur with uncontrolled mechanical or chemical methods.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If multiple processing steps are implemented to improve protein quality, then amino acid profiles are enhanced, but process complexity and time increase

Engineering Contradiction:
Improveamino acid profile qualityVSAvoidprocessing steps
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple processing functions into integrated steps. For example, the mechanical separation process simultaneously achieves particle size reduction and fat removal, while the enzymatic treatment step combines protein hydrolysis with amino acid profile optimization. This merging reduces the number of discrete operations while maintaining high protein quality.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies preliminary action by performing preliminary mechanical separation and fat removal before the main protein processing steps. This preliminary preparation simplifies subsequent processing by working with pre-separated protein material, reducing the complexity of later steps while ensuring high amino acid profile quality.

Inventive Principle:
Principle #10Preliminary action
