| 摘 要： | 将表面共价接有杀菌活性官能团的纳米SiOx配制保鲜涂膜剂，对芒果进行常温保鲜试验，并与壳聚糖及未修饰纳米SiOx配制的涂膜剂作比较。结果表明，处理组在21d的常温贮藏过程中其硬度、可滴定酸、总糖、可溶性总固形物的变化趋势明显低于空白；经共价修饰纳米SiOx处理的芒果其发病率下降90．38％，商品果率达92．31％。

| Abstract: | A coting preservation reagent including nano-SiOx which was covalent bonded with disinfection functional group was manufactured and tried on mango at room tempreture,and compared with the preservation reagent of chitosan and nano- SiOx.The results of the test showed that the physiology and biochemistry variables such as hardness,chlorophyll,saccharide, soluble solid content of the coated mango changed significantly more slowly than those of untreated group.The morbidity rate of the mango treated with covalent bounding nano-SiOx reduced 90.38% and the good-fruit rate was 92.31%. |

| Keywords: | nano-SiOx antibacterial chitosan mango freshness |
