Chinese:为什么世界卫生组织将罐头食品列入垃圾食品

类别: 餐饮食品

问题:
为什么世界卫生组织将罐头食品列入垃圾食品

回答:
在商场,方便、美味的罐头食品琳琅满目,越来越受到消费者,尤其是那些生活节奏快速的消费者的认可。近年来,以肉类罐头、鱼类罐头、八宝粥罐头和水果罐头为核心的罐头产品的国内市场发展势头强劲。然而,世界卫生组织却将罐头食品列入垃圾食品之列,颇令人感到意外。那么,是什么原因让不少人喜欢的罐头食品成为垃圾食品呢?原来,罐头食品的加工和制作工艺是导致其沦落为垃圾食品的原因

  问题一:蛋白质变性
  肉类金属罐头、肉类软罐头都采用121℃的高温高压加热方式进行mj。肉制食品在受到高温加热时,特别是在121℃下长时间受热时,肉中含有的人体必需的氨基酸会遭到严重破坏。

  问题二:维生素破坏
  有研究数据表明,在罐头加工的过程中,肉中的维生素包括维生素B 1(硫氨素)、维生素B2(核黄素)、烟酸、维生素B6、叶酸等,会受到一定的损失。特别是维生素B1,在中性及碱性溶液中遇热,很容易受到破坏,会损失15%~25%,维生素B2会损失10%,维生素B5会损失20%~30%,尼克酸会损失掉一部分。
  而对于水果罐头,维生素C几乎全被破坏。

  问题三:糖分高
  很多水果类罐头为了增加口感,都添加了大量的糖。这些糖分被摄入人体后,可在短时间内导致血糖大幅度升高。另外,研究还发现,糖可以改变蛋白质的分子结构,从而会影响免疫系统功能。

  问题四:水果罐头三成不合格
  国家质量监督检验检疫总局2004年11月底公布的一项{zx1}国家监督抽查结果显示,水果罐头质量近3成不合格(不涉及出口产品)。

回答:
可能是其中含有防腐剂等人工有害成分,营养又不高
