ZnO nanoparticles combined radio frequency heating: A novel method to control microorganism and improve product quality of prepared carrots

ZnO nanoparticles combined with radio frequency heating achieved logarithmic reduction of bacterial population and met China's national standard while preserving the color, texture and nutrition better. This information can be helpful for food processing industries to produce high quality sterilized prepared carrots and this same approach can be applied to many other prepared food formulations.
