Electron Beam Irradiation Improves Microbiological Safety of Chilled Poultry Meat

Strategic Insights -

Researchers from Almaty Technological University have conducted a study to investigate the effectiveness of electron beam irradiation in improving the microbiological safety and quality of chilled poultry meat produced in Kazakhstan. The study highlights the importance of extending the shelf life of chilled meat, which has a limited time frame for sale, and the potential of electron beam irradiation as a non-thermal preservation technique. The findings show that electron beam irradiation at doses of 2-4 kGy can significantly decrease total aerobic and facultative anaerobic microorganisms, and extend the shelf life of chilled poultry meat up to 5-6 days.

Key Takeaways:

  • Electron beam irradiation is a new non-thermal meat preservation technique with low cost, avoidance of contamination, and antibacterial effects.
  • The study found that electron beam irradiation at doses of 2-4 kGy effectively improves microbiological safety and extends the shelf life of chilled poultry meat up to 5-6 days.
  • The pH measurements remained stable at low doses, while higher doses resulted in a slight decrease.
  • The moisture, protein, fat, and ash content were also evaluated and showed minimal changes as functions of irradiation dose.
  • The study concluded that electron beam irradiation is a promising solution for the modern poultry meat industry.
  • The research was conducted with financial support from the Ministry of Science and Higher Education of the Republic of Kazakhstan.

Statistics:

  • The study evaluated the effect of electron beam irradiation on the microbiological and physicochemical quality of chilled poultry meat produced in Kazakhstan.
  • The samples were electron-beam-treated at doses of 2, 4, 6, and 8 kGy.
  • The study found a significant decrease in total aerobic and facultative anaerobic microorganisms, with no detectable levels of Salmonella spp. and Listeria monocytogenes in the irradiated samples.
  • The pH measurements remained stable at low doses, while higher doses resulted in a slight decrease.
