The effect of mixing chitosan/nano-ZnO coating with different content of nano-ZnO on quality of cherry tomato was studied. The SEM pictures showed that the nanoparticles had a better dispersion in chitosan matrix at a relative low content of 1% and 2%. However, the aggregation of nanoparticles occurred when the content of nano- ZnO was up to 3wt%. The chitosan/nano-ZnO coating with 1% content of nano-ZnO had a better preservation effect on improving the sensory quality, decreasing the weight loss, Vc and acid content of cherry tomato. In contra...
