Understanding key volatiles in semi-moist pet foods treated with electron beam and X-ray irradiation

Key Points

• Key volatiles from semi-moist pet foods shifted significantly after irradiation treatments.
• Irradiation with electron beam and x-ray improved the nutritional quality while reducing harmful compounds.
• This observational analysis assessed the impact of electron beam and x-ray irradiation on food safety.
• These findings suggest that irradiation may enhance pet food safety, but implications for nutrition require further exploration.
