生活妙招:五类隔夜菜千万不能再吃 引发食物中毒

海纳百川,有容乃大。壁立千仞,无欲则刚。

    “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。以下几种菜久置尤其有害。

    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。

    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。

 

    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。

    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。

    汤别放金属器皿里。

      熬汤费时费力,人们往往熬一大锅,一连吃好几天。剩汤如果长时间盛在铝锅、铁锅内,会析出对人体有害的物质。存汤的最好办法是,汤里不要放盐之类的调味料,煮好汤用干净的勺子盛出当天要喝的,喝不完的,最好是用瓦锅或保鲜盒存放在冰箱里。
