Solution Overview

Problem

The utilization of livestock and poultry blood is limited due to its unpleasant flavor and color, and there is a lack of knowledge about taste-active and taste-modulating peptides derived from these sources, hindering their use in food and pharmaceutical preparations.

Innovation Solution

The development of specific amino acid sequences from livestock and poultry blood-derived peptides, such as Pro-Val-Leu-Lys (SEQ ID NO: 1) and Glu-Ala-Glu-Phe-Asp (SEQ ID NO: 3), which can impart taste-modulating effects like salt-reducing, salt-enhancing, umami, and kokumi effects, and their use in a protein hydrolysate and taste-modulating composition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If livestock and poultry blood is used directly in food and pharmaceutical preparations, then the valuable proteins and nutrients can be utilized, but the unpleasant flavor and color limit its application

Engineering Contradiction:
Improveutilization of blood proteins and nutrientsVSAvoidunpleasant flavor and color
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The blood proteins are segmented into smaller peptide units through enzymatic hydrolysis. This breakdown transforms the large protein molecules into smaller, more manageable peptide fragments that have improved sensory properties while retaining nutritional value. The segmentation process specifically targets the protein structure to produce peptides with desirable taste characteristics.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The physical and chemical parameters of the blood proteins are changed through controlled enzymatic hydrolysis. By adjusting parameters such as enzyme type, hydrolysis time, temperature, and pH, the protein structure is transformed into peptides with modified sensory properties. This parameter change converts the unpleasant flavor and color of whole blood into acceptable taste profiles suitable for food and pharmaceutical applications.

Inventive Principle:
Principle #35Parameter changes

2Object-affected harmful factors

If taste-active and taste-modulating peptides are generated from chicken blood, then the taste quality can be improved, but the limited knowledge of chicken blood composition makes identification challenging

Engineering Contradiction:
Improvetaste qualityVSAvoidlimited knowledge of blood composition
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

Enzymes are used as intermediaries to facilitate the breakdown of blood proteins into identifiable peptides. The enzymatic hydrolysis process acts as a mediator that systematically cleaves peptide bonds, generating a profile of taste-active peptides that can be characterized and identified. This intermediary process converts the complex, poorly understood blood protein mixture into a more analyzable peptide composition.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Traditional mechanical or chemical digestion methods are replaced with enzymatic hydrolysis to generate taste-active peptides. The biological enzyme system provides selective and controlled breakdown of proteins, replacing crude mechanical disruption or harsh chemical treatment. This substitution enables gentle, specific cleavage that preserves the integrity of taste-active peptide sequences while making them identifiable through analytical methods.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
