吃不完也别留着了,这几种隔夜菜毒素增加10倍!

段时间网络上关于“隔夜菜致癌”的说法被炒得沸沸扬扬,这种说法不无道理。“隔夜菜”并不单指放了一夜的菜,放置时间超过8—10个小时,就应该算隔夜了。而导致食物中有毒成分增加有两个方面的原因,第一是因为食物中的化学物质产生了致癌物,如亚硝酸盐,即使加热也不能去除。另一个原因是在放置时受到了外来细菌的二次污染。特别是下面4种隔夜菜回锅炒会导致其中的毒素和致癌物增加10倍,大家可要高度警惕了!

1、绿叶菜隔夜最危险

通常茎叶类蔬菜硝酸盐含量最高,瓜类蔬菜稍低,根茎类和花菜类居中。因此,如果同时购买了大量蔬菜,应该先吃叶菜类的,比如大白菜、菠菜等。如果准备多做一些菜第二天热着吃,应尽量少做茎叶类蔬菜,而选择瓜类蔬菜。

2、隔夜海鲜损肝肾

螃蟹、鱼类、虾类等海鲜,隔夜后会产生蛋白质降解物,损伤肝、肾功能。如果实在买多了,可以把生海鲜用保鲜袋或保鲜盒装好,放入冰箱冷冻,下次再烹调。

3、半熟蛋易致病

很多人都爱吃蛋黄软软的半熟蛋,可是这种蛋杀菌不彻底,再加上鸡蛋营养丰富,格外容易滋生细菌,食用后会发生危险。如果蛋已熟透,而且低温密封保存得当,隔夜再吃是没有问题的。

4、银耳蘑菇要当心

不论是野生的还是人工栽培的银耳、蘑菇等,都容易残留很多硝酸盐。如果放的时间实在有点久,就只能忍痛扔掉。
