Electrostatic Spray for Meat Pathogen Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current food preservation methods, particularly in the meat industry, face challenges in effectively reducing foodborne pathogens like Salmonella, E. coli O157:H7, and Listeria monocytogenes without resorting to traditional antibiotics, which can lead to antibiotic resistance, and often require significant water usage and energy.
Innovation Solution
The use of electrostatic spray systems delivering plant-based antimicrobial agents, such as olive extract, hibiscus extract, and lactic acid, which induce electrostatic binding to pathogens and meat surfaces, reducing microbial loads efficiently and minimizing water and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional antibiotics are used to reduce foodborne pathogens, then pathogen reduction is effective, but antibiotic resistance develops and public health crisis emerges
Solution Approach 1:
The patent transitions from using traditional antibiotics to plant-based antimicrobial compounds, changing the chemical parameter of the antimicrobial agent. This substitution maintains pathogen reduction effectiveness while eliminating the development of antibiotic resistance, as plant-based compounds work through different mechanisms that do not select for resistant bacterial strains.
Solution Approach 2:
The patent employs plant-based antimicrobial compounds that can be applied topically and do not require systemic administration. These compounds act locally on the meat surface to reduce pathogens without persisting in the food chain, thereby avoiding the long-term selection pressure that leads to antibiotic resistance while maintaining effective pathogen reduction.
2Reliability
If lactic acid solutions are used as antimicrobial agents, then antimicrobial action is effective, but significant water consumption is required
Solution Approach 1:
The patent changes the concentration parameter by using highly concentrated plant-based antimicrobial extracts and essential oils instead of dilute lactic acid solutions. These concentrated formulations achieve effective antimicrobial action with minimal application volume, thereby dramatically reducing water consumption while maintaining pathogen reduction effectiveness.
Solution Approach 2:
The patent employs composite plant-based formulations combining multiple antimicrobial compounds (essential oils, extracts, and other natural antimicrobials) that work synergistically. This composite approach enhances antimicrobial effectiveness per unit volume, allowing reduced water usage compared to single-component lactic acid systems while maintaining or improving pathogen reduction.
3Object-affected harmful factors
If natural plant-based antimicrobials are used instead of synthetic preservatives, then consumer safety and naturalness are improved, but cost increases
Solution Approach 1:
The patent extracts and concentrates the active antimicrobial components from plant materials, isolating the essential oils and bioactive compounds that provide pathogen reduction. This extraction process removes unnecessary bulk plant material, reducing the quantity of expensive natural ingredients needed while maintaining the safety and naturalness benefits of plant-based antimicrobials.
Solution Approach 2:
The patent changes the concentration and purity parameters of plant-based antimicrobial agents through extraction and formulation processes. By providing highly concentrated, standardized formulations, the patent reduces the total quantity of natural ingredients required per treatment, thereby lowering overall cost while maintaining the consumer safety and naturalness advantages of plant-based alternatives to synthetic preservatives.
