Innovative Non-thermal Processing Technologies for Enhancing Pet Food Safety and Quality: A Comprehensive Review of Publications, Patents, and Market Trends

Abstract

Non-thermal processing technologies have emerged as promising alternatives to traditional heat treatments in the pet food industry. To date, no prior review has systematically integrated peer-reviewed publications, patents, and commercial product launches on non-thermal technologies in the pet food sector during 2014-2024. This integrative approach fills an important gap by linking scientific evidence with innovation activity and market adoption. Unlike conventional thermal methods, which often degrade heat-sensitive nutrients and alter the sensory qualities of pet food, these innovative techniques leverage physical principles to inactivate pathogens while preserving the product's nutritional and sensory integrity. This review explores the application of key non-thermal technologies, inclu
