Cold plasma technology offers a sustainable, non-thermal strategy for food preservation that inactivates microbes, enzymes, allergens, pesticide residues, and toxins with minimal impact on nutritional and sensory quality. Utilizing reactive species, UV radiation, and radical chemistry, cold plasma ensures safe, minimally processed foods while preserving taste, texture, and nutrients. Its potential extends to active packaging for shelf-life extension and waste reduction. Optimal performance depends on carefully controlled parameters, gas composition, pressure, electric field, frequency, and temperature—and understanding substrate and microbial diversity. Though promising, cold plasma is not a universal fix; integrated, hybrid approaches are essential to effectively safeguard food safety and quality in complex systems.
