Abstract：

In　this　paper,　the　orthogonal　test　was　designed　to　optimize　the　preparation　conditions　of　TiO2/SPI　composite　film,　and　its　antibacterial　properties　were　measured.　The　optimized　TiO2/SPI　composite　film　was　applied　in　strawberry　at　low　temperature,　and　the　weight　loss　rate,　the　total　number　of　colonies,　the　soluble　monosaccharide　and　color　were　measured　during　storage.　The　results　showed　that　the　optimum　condition　was　as　follows:　the　TiO2　dosage　2.00g/150mL,　the　SPI　concentration　4.50　g/150　mL　and　the　glycerol　concentrations　3.75　g/150　mL.　The　optimized　TiO2/SPI　composite　film　can　restrain　the　growth　of　E.　coli　and　S.　aureus.　After　8　days　storage　at　-4,　strawberries　coated　with　the　TiO2/SPI　composite　film　had　lower　weight　loss　rate　by　17.3%　and　lower　total　bacterial　count　by　97.0%　than　that　uncoated　with　film.　Besides,　changes　of　color　difference　and　soluble　monosaccharide　content　are　steadier　than　the　controls.　The　results　proved　that　the　storage　period　of　strawberries　was　prolonged　at　low　temperature　by　coating　optimized　TiO2/SPI　composite　film.　©,　2015,　Chinese　Institute　of　Food　Science　and　Technology.　All　right　reserved.
