Atmospheric cold plasma (ACP) is a promising non‐thermal technology in food industry. In this study, a dielectric barrier discharge (DBD)‐ACP exhibited strong bactericidal effect on Escherichia coli in apple juice. Under a 30 to 50 W input power, less than 40 s treatment time was required for DBD‐AC...
