Default 即热式电热水龙头|拼装水果存在健康隐患

 

  核心提示:市场上存在一些拼装好的水果,看起来颜色鲜艳,很好看,一买就可马上食用,方便,且满足多样 化的需求。但其实切开了的水果容易被细菌感染,食用后易引起胃肠炎症。且包装用的保鲜膜也存在 风险。
  经常逛超市的消费者肯定不难发现,在水果销售区,一盒盒削好的水果拼在一起,不仅品种丰富、颜色好看, 而且省去了自己清洗的步骤,打开就可以直接食用,这也成为很多消费者的选择。不过,针对超市内出现的各种“ 拼装”水果发布消费警示,专家提醒广大消费者,“拼盘”水果虽然食用方便、价格便宜,但存在健康隐患,购买 时一定要谨慎。
  切开水果易流失营养素
  不少家庭喜欢买拼盘水果,认为可以花较少的钱买到更多品种的水果,因此可以得到更全面的营养。不过,专 家指出,这种切开的水果,即热式电热水龙头,其实极易造成营养素的流失。
  专家表示,新鲜的水果蔬菜含有丰富的维生素C,也是人们获取维生素C的主要来源。而维生素C的最大特点 是,在酸性环境下稳定,遇氧、热、光、碱时即会促进氧化被破坏。切开后的水果完全暴露在空气中,因此会造成 维生素C的大量损失,一些天然色素也会被氧化、流失。水果切得越小,暴露的时间越长,维生素C的损失就越大 。英国消费者协会曾测试过13个样本的预先包装好的切开果蔬,结果有4个样本的维生素C含量至少降低了一半 。随着营养成分的流失,果蔬的水分也会随之流失,造成口感下降。
  另外,快热电热水龙头,专家指出,这种去皮拼装水果的新鲜程度也很难保证,一些超市或商家甚至将要坏的水果或已坏了一半的水果削 皮或削掉坏的部分,将剩下的水果处理成拼装水果,这种水果的安全性则值得怀疑。
  一旦发生霉变,细菌会在水果内部不断繁殖,并产生有毒物质,食用后容易引发胃肠炎症。另外还有,各种水 果拼在一起本身可能也会相互作用,导致口味变化。
