Extending Shelf Life of Poultry and Red Meat by Irradiation Processing

Area of Science:

• Food Science
• Microbiology
• Radiation Technology

Background:

• Foodborne pathogens pose significant risks to public health.
• Extending the shelf life of perishable foods like meat is crucial for reducing waste and improving availability.
• Traditional preservation methods may impact sensory and nutritional qualities.

Purpose of the Study:

• To evaluate the efficacy of ionizing radiation in reducing microbial load and extending the shelf life of refrigerated meats.
• To assess the impact of ionizing radiation on the nutritional and sensory properties of poultry and red meats.
• To investigate the synergistic effects of combining ionizing radiation with packaging technologies.

Main Methods:

• Irradiation of refrigerated poultry, pork, and beef with varying doses of ionizing radiation.
• Microbiological analysis to determine pathogen reduction.
• Sensory and nutritional evaluations of treated meat products.
• Application of combination treatments with vacuum packaging or modified atmosphere packaging.

Main Results:

• Ionizing radiation significantly reduced or eliminated foodborne pathogens.
• Shelf life of treated meats (poultry, pork, beef) was substantially extended.
• Desired nutritional and sensory properties were preserved.
• Combination treatments yielded superior results compared to irradiation alone.

Conclusions:

• Ionizing radiation is a viable technology for enhancing food safety and extending the shelf life of refrigerated meats.
• Preservation of quality attributes is achievable with appropriate irradiation doses.
• Synergistic effects observed with combined treatments highlight potential for optimized food preservation strategies.
