：Tea polyphenol was added to the soy protein isolate and the tea polyphenol-incorporated soy protein isolate antibacterial film-coating was made. In order to study the effect of the film-coating on fresh preservation of sweet cherry, the changes of sensory index, firmness, rotting index, soluble solid and vitamin C content of sweet cherry treated with the film-coating were studied during the storage under the room temperature. The results indicated that the film-coating could significantly reduce the rotting rate of sweet cherry to a certain extent, delay the decline of the fruit’s firmness, vitamin C and soluble solid content, inhibit the decline of sensory index and keep storage quality of sensory. It was found that film-coating made with 5% soy protein isolate blended with 200βmg/kg tea polyphenol achieved the best preservation effect on sweet cherry, which can prolong the shelf life from 2βd to 8βd as compared with the control under the room temperature.
