Plasma Technology Extends the Shelf Life of Chicken Meat by at Least 5 Days
Plasma Technology Extends the Shelf Life of Chicken Meat by at Least 5 Days
Based on microbiological analysis conducted on chicken meat samples treated with the plasma-basedsystem at the poultry slaughterhouse stage, a significant modification and reduction of spoilage-related microbial populations was observed compared to untreated control samples.
Microbial Profile Results
Taxonomic analysis at both class and order levels demonstrated that plasma treatment:
Significantly reduced the relative abundance of Gammaproteobacteria and Enterobacterales, which are commonly associated with meat spoilage and reduced shelf life
Increased the dominance of more stable bacterial groups such as Bacilli / Lactobacillales, indicating a shift toward a less spoilage-prone microbial community
Reduced overall microbial diversity associated with rapid deterioration under refrigerated conditions
Compared to control groups, plasma-treated samples showed a clear suppression of spoilage-related microbial taxa, confirming the antimicrobial effectiveness of the system without the use of chemicals.
Shelf Life Performance Under Retail Conditions
Based on microbial dynamics and cold storage behavior:
Chicken meat treated with plasma maintained acceptable microbiological quality for at least 5 additional days
Storage conditions: refrigerated retail conditions (~4 °C)
Treated samples showed delayed microbial growth compared to untreated controls
This extension is directly correlated with the observed reduction in spoilage-associated bacterial groups identified in the microbiome analysis.
Industrial and Retail Impact
The application of this plasma system in poultry slaughterhouses provides:
Minimum 5-day shelf life extension for fresh chicken meat in supermarkets
Reduced microbial load without altering meat color, texture, or safety
Lower product returns and food waste at the retail level
A chemical-free and residue-free preservation solution compliant with modern food safety standards
Conclusion
Microbiological profiling confirms that plasma treatment effectively alters the microbial ecosystem of chicken meat by suppressing spoilage-related bacteria and stabilizing microbial growth during refrigerated storage.
As a result, the technology enables a measurable and reproducible extension of poultry meat shelf life, offering a practical and scalable solution for slaughterhouses, cold chains, and supermarket distribution systems.
