Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling Salmonella growth in animal feed, particularly in the feed industry, face challenges due to the use of formaldehyde, which is banned in certain regions and poses safety concerns, and existing alternatives lack effectiveness and safety, especially in high pH environments.
Innovation Solution
Compositions containing one or more peroxyacids, such as perpropionic acid and peracetic acid, combined with organic acids or esters, are used to control Salmonella growth in animal feed, providing antimicrobial activity while being formaldehyde-free and effective at high pH levels, with a buffered solution to mitigate corrosion risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If formaldehyde is used to control Salmonella growth in animal feed, then pathogen control effectiveness is improved, but safety concerns and regulatory bans worsen
Solution Approach 1:
The patent extracts and eliminates formaldehyde from the feed treatment system, replacing it with a formaldehyde-free composition containing organic acids, esters, and peroxycarboxylic acids. This removes the harmful substance while maintaining the pathogen control function through alternative active ingredients that achieve Salmonella reduction without the safety and regulatory issues associated with formaldehyde.
Solution Approach 2:
The patent changes the chemical composition parameters by formulating a multi-component system with specific pH ranges (adjusted to 2-12 using buffers) and specific concentrations of organic acids, esters, and peroxycarboxylic acids. This parameter optimization allows the composition to maintain effectiveness against Salmonella while being safe for animal consumption and compliant with regulations that ban formaldehyde.
2Object-affected harmful factors
If existing alternative antimicrobials are used instead of formaldehyde, then safety concerns are reduced, but effectiveness against Salmonella and other pathogens worsens
Solution Approach 1:
The patent merges multiple antimicrobial components into a single composition: organic acids (such as acetic, propionic, or formic acid), esters (such as ethyl acetate or propyl propionate), and peroxycarboxylic acids (such as peracetic acid or perpropionic acid). This combination creates a synergistic effect that enhances pathogen control effectiveness beyond what individual components could achieve alone, while maintaining safety for animal feed applications.
Solution Approach 2:
The patent creates a composite antimicrobial formulation that integrates multiple chemical classes (organic acids, esters, and peroxycarboxylic acids) with complementary mechanisms of action. This composite approach allows the composition to effectively control Salmonella and other pathogens through multiple simultaneous mechanisms, ensuring high reliability without relying on banned substances like formaldehyde.
3Reliability
If peroxycarboxylic acids are used to control pathogens, then antimicrobial effectiveness is improved, but corrosion risk to equipment worsens
Solution Approach 1:
The patent optimizes the pH parameter of the composition by adjusting it to ranges of 2-12 using appropriate buffers, which reduces the corrosivity of peroxycarboxylic acids to feed mill equipment while preserving their antimicrobial effectiveness. This parameter control allows the composition to maintain pathogen control capabilities without causing excessive corrosion to stainless steel and other equipment materials.
Solution Approach 2:
The patent introduces buffers as intermediary substances that mediate between the peroxycarboxylic acids and the equipment. These buffers control the pH and chemical environment, reducing the direct corrosive interaction between the peroxycarboxylic acids and metal surfaces while allowing the antimicrobial action to proceed effectively against pathogens in the feed.
4Reliability
If high concentration of antimicrobial agents is used to ensure pathogen control, then effectiveness against Salmonella is improved, but impact on feed quality and animal performance worsens
Solution Approach 1:
The patent applies partial action by using optimized concentrations of antimicrobial components that are sufficient to achieve the required Salmonella reduction (typically 3-5 log reduction) without excessive amounts that could harm feed quality or animal performance. The composition is formulated to achieve effective pathogen control at moderate concentrations through the synergistic interaction of multiple components.
Solution Approach 2:
The patent optimizes concentration parameters by adjusting the levels of organic acids, esters, and peroxycarboxylic acids to achieve maximum Salmonella control effectiveness while minimizing negative impacts on feed quality and animal health. This includes optimizing the pH range and the relative proportions of different active ingredients to ensure safety and effectiveness simultaneously.
