Microbiocidal Composition for Poultry Carcass Processing

Solution Overview

Problem

Poultry processing faces challenges in achieving effective microbiological control against pathogens like Campylobacter, with existing methods often requiring high biocide levels that can leave residues and affect the quality of poultry meat products.

Innovation Solution

The use of combinations of microbiocides and surfactants, specifically 1,3-dibromo-5,5-dialkylhydantoins, N,N′-bromochloro-5,5-dialkylhydantoins, chlorine dioxide, and amine oxides or betaines, applied in water to poultry carcasses during processing, enhancing microbiocidal efficacy while reducing biocide residues and maintaining product quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high levels of biocide are used to achieve effective microbiocidal control, then microbiocidal efficacy is improved, but biocide residues increase and product quality deteriorates

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the chemical parameters of the microbiocidal composition by combining biocides with specific surfactants (anionic, cationic, nonionic, or amphoteric types). This parameter change enables enhanced microbiocidal efficacy against Campylobacter and other pathogens while using lower biocide concentrations, thereby reducing residues and maintaining product quality.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates composite microbiocidal compositions by combining biocides with surfactants. These composite materials exhibit synergistic effects where the surfactant component enhances the biocide's microbiocidal activity, allowing effective pathogen control at reduced biocide levels, thus resolving the contradiction between efficacy and residue formation.

Inventive Principle:
Principle #40Composite materials

2Object-affected harmful factors

If reduced levels of biocide are used to minimize residues, then product quality is improved, but microbiocidal efficacy decreases

Engineering Contradiction:
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent modifies the composition parameters by introducing surfactants that enhance biocide activity. This allows the system to achieve the same or better microbiocidal efficacy at lower biocide concentrations, thereby minimizing residues while maintaining food safety goals.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The surfactant acts as an intermediary substance that mediates between the biocide and the pathogen. The surfactant enhances the biocide's effectiveness through synergistic interactions, enabling reduced biocide usage while maintaining adequate microbiocidal control.

Inventive Principle:
Principle #24Intermediary (Mediator)
