莱菔子多糖在水果保鲜中的应用初探

Preliminary research on preservation of fruits with polysaccharide from Semen Raphani

采用莱菔子多糖作为涂膜保鲜剂,在常温(25±2℃)条件下,分别以2、4、6、8g/L对苹果、樱桃番茄进行涂膜保鲜处理,测定了在贮藏过程中苹果、樱桃番茄的失重率、总糖、感官等理化性能指标。实验表明,莱菔子多糖能抑制苹果、樱桃番茄体内营养物质的消耗,降低失水率,延缓果实的衰老过程,且6g/L的莱菔子多糖对两种水果的保鲜效果最好。

Polysaccharide from Semen Raphani was used as the preservation material and the concentration of 2,4,6 and 8g/L were used with apple and cherry tomato at the ambient temperature（25 ±2℃）.Indexes such as： weight-lost rate, total sugar and sense-index were assayed during storage. The results indicated a positive correlationship between the preservation effects and polysaccharide. During the storage period, polysaccharide could decrease the fruit nutrition loss and weight-lost rate,and delay the senescent course.And the concentration 6g/L has the best result of preservation.
