Nisin在草莓保鲜中的应用研究

Research of application nisin in preservation of strawberry

研究Nisin对草莓保鲜的影响。使用浓度为0.1,0.2,0.3g/kg的Nisin悬浮液喷洒的草莓,对贮藏期间草莓的腐烂率、失重率、可滴定酸含量、VC的含量进行测定。结果表明:保鲜箱中喷洒0.1g/kgNisin的草莓保鲜效果最好,将其放置6d后腐败率为40%,重量损失率达到24%,VC的损失率小于10%、总酸含量为原始含量的75%。说明使用Nisin对草莓进行保鲜能保持其光鲜的色泽和VC、可滴定酸等营养成分。

The paper has studied the influence of Nisin that maintaining freshness of the strawberry.We use Nisin of diffrient density of 0.1,0.2,0.3 g/kg spraying on the strawberry respectively,we measure the stage of storage of the strawberry s decay rate,weightlessness rate,the titration acid content,the Vitamin C content carry.The result shows that after-crops the box of the strawberry which was sprayed in 0.1 g/kg Nisin gets the best effect of maintaining freshness.After laying aside for 6 days the corruption rat...
