Processing sheep milk by cold plasma technology: Impacts on the microbial inactivation, physicochemical characteristics, and protein structure

Abstract This study aimed to evaluate the impacts of cold plasma processing time of 30 s, 180 s, and 300 s (CSM30, CSM180, and CSM300) on the microbial inactivation, physicochemical characteristics, and protein structure of raw sheep milk. Pasteurized sheep milk was used as the positive control. The microbial inactivation rate of CSM300 sample was similar to the pasteurized sample, and the former had a significantly smaller casein micelle size and polydispersity index (P
