摘要: 采用白芨多糖胶作为涂膜保鲜剂试材,在常温(均温20℃)条件下分别以0.6%、1%、2%浓度对樱桃番茄进行涂膜保鲜处理,以常温和冷藏(0~4℃)对照组作对比。测定了在贮藏过程中(0~12d)樱桃番茄的感官指标、总酸度、总糖、可溶性蛋白、SOD、VC含量的变化以及其呼吸强度、硬度、失重率等理化性能指标。实验表明,白芨多糖胶膜能抑制樱桃番茄体内营养物质的消耗,降低失水率,抑制其呼吸强度,延缓果实的衰老过程。

Abstract: Bletilla glucomannan(Bg)was used as the preservation material.The concentration of 0.6%,1% and 2% were used at the ambient temperature (about 20℃),in comparison with no Bg film at ambient temperature and refigerafion(0~4℃).Indexes such as:sense-index,total acidity sugar,solution-protein,SOD,Vitamin C,respiration rate,hardness and weight-lost rate were assayed during storage.The results indicated a positive correlationship between the preservation effects and Bg.During the storage period,Bg could decrease the fruit nutrion loss and weigh-loss rate,and inhibits the respiration and delay the senescent course.
