Abstract: “Shamidou”cherry were selected as experimental material. The effects of different thickness anti-fog film packaging methods on cherry were investigated by analyzing physical and chemical indexes and nutrition components during storage. The research results indicated as follows:the treatments of anti-fog film packaging could effectively reduce the cherry decay rate, delay the decrease of VCcontent, maintain high content of titratable acid and soluble solids and inhibit increase of pH significantly. The descent speed of activity of catalase (CAT) could be cut down and the activity of polyphenol oxidase (PPO) could also be maintained at a lower level. The thickness of 50μm anti-fog film packaging treatment could achieve better preservation effect.On the 70 th day of storage, the decay rate of cherry which was packed by thickness of 50μm anti-fog film was controlled effectively in 7.78%, and the control group decay rate reached 16.67%, which was 2.3 times of the thickness of 50μm anti-fog film packaging treatment, and the difference was extremely significant (p<0.05) .
