      养生界一直有种说法,夏季隔夜菜,特别是隔夜蔬菜不能吃,说隔夜菜中有大量细菌,而且亚硝酸盐含量很高。真是这样的吗?如果超标,到底有多严重?

        为了测测隔夜菜亚硝酸盐的含量,实验小组请厨师烧了4个菜:炒青菜、韭菜炒蛋、红烧肉和红烧鲫鱼。4个菜烧好后,为了让大家对剩菜中亚硝酸盐含量变化有个更客观的了解,特地将4个菜分成了4份,分别装入一次性降解餐盒,包上保鲜膜后,分别贴上半小时、6小时、18小时、24小时的标签。然后,将这些样本都放进实验室冰箱,在4℃下冷藏,这个温度也是普通家用冰箱设置的温度。


      放置半小时


        出锅后半小时,炒青菜、韭菜炒蛋、红烧肉这三个菜的检测结果是,亚硝酸盐含量都没有超过我国《食品中污染物限量标准》的最高限值。但红烧肉中亚硝酸盐含量比韭菜炒蛋和炒青菜要高。

        对此实验人员说,肉类菜肴一般比蔬菜类加入更多的调味料,调味料中本身就含有硝酸盐,这些硝酸盐被微生物转化为亚硝酸盐,就导致了红烧肉中亚硝酸盐含量较高。


      放置6小时


        6小时后,差不多为中饭到晚饭的时间间隔。许多老年人或者双职工家庭在休息天、中午烧的菜,晚上再吃很普遍。


        实验人员打开冰箱,把贴有“6小时”标签的炒青菜、韭菜炒蛋、红烧肉和红烧鲫鱼取出来,然后放进微波炉,用中低火加热1分钟,拿出微波炉后,这些菜肴看起来仍然很新鲜。


        实验人员对这些菜肴的亚硝酸盐含量进行了测定,结果发现,6小时后剩菜中亚硝酸盐含量都有所增加,炒青菜增加了16%,韭菜炒蛋增加了6%,红烧肉增加了70%。其中,红烧肉中亚硝酸盐含量已超过了国家《食品中污染物限量标准》中“肉类3mg/kg”的限量标准。


      放置18小时


        18小时后,实验人员又从冰箱中拿出贴有“18小时”标签的4个菜,用微波炉加热后作检测。检测结果发现,炒青菜中亚硝酸盐含量增幅非常大,比6小时增加了443%,红烧鲫鱼增加54%,韭菜炒蛋增加47%,红烧肉中亚硝酸盐含量变化

      不大。

        从这实验看出,隔夜菜放到第二天中午,炒青菜、红烧肉、红烧鲫鱼亚硝酸盐含量都超过了国家标准。


      放置24小时


        距离4个菜烧好的时间差不多过去24小时后,实验人员从冰箱中拿出最后一批贴有“24小时”标签的4个菜肴,同样用微波炉加热后作检测。检测结果发现,跟18小时相比,4个菜肴亚硝酸盐含量继续大幅增加,且全部超过了《食品中污染物限量标准》的限量标准。

        实验人员说,24小时后,微生物分解了大量蛋白质化合物,促使硝酸盐转化为亚硝酸盐。


      【摄入3克亚硝酸盐即可中毒致人死亡】

        亚硝酸盐可使血中低铁血红蛋白氧化成高铁血红蛋白,失去运氧的功能,致使组织缺氧,重则死亡。长期食用可引起食管癌、胃癌、肝癌和大肠癌等疾病。成人摄入0.2至0.5克即可引起中毒,3克即可致死。简单说,今后按量做菜,切勿剩菜。

      The National Physical Fitness Survey (NPFS), conducted by the National Council on Physical Fitness and Sports (NCPFS) in Taiwan in 1999 and repeated in 2001 provides an opportunity to study the prevalence of overweight and obesity in nationally representative samples of 6 year olds.
      Along with the obvious choice of conjuration, illusion is quite possibly even more important as you will read in the gameplay section. Save electricity (or gas) by hanging clothes out to dry when you can. Shopping can often provide a sense of optimism and euphoria, which is much needed during a widespread economic downturn.
      The computer generates a price, which in most cases is about a third of the value.. This turned out to be the first step in an escape plan straight out of some wacky movie where the villain is played by Larry the Cable Guy.. To this day, I still think that the Ravens should have hired him to be their next head coach.
      You think that if it was associated with the spinning, it would continue as long as the spinning continues.. For some reason, they decided to accomplish this goal by banning all of the children's favorite books. I recently adopted two baby girls and this website has helped out tremendously.
      But amid a glut of new condo developments, there is nonetheless a reluctance to spend too much on too little.. The one that really threw me though was Shen lon because even though he acts very masculine he looks fairly effeminate at times and it isn't completely clear at times until they start using the right words with him..
      Her grandmother couldn't support herself, let alone Ama and her three siblings.(sound of Ama speaking)Ama says a friend told her to come to Accra where she was a storekeeper earning $12 a month. While brushing her teeth, taking a bath and changing her clothes daily may have been enough to get by during early grade school, your teen may need to take on a more complex hygiene routine as puberty sets in.
      It's not like we can't make another one for free.". Buy lots for shoes and they are easy to use for storage!Work/Play Clothes Drawer off the FloorJeans, sweatpants, t shirts, etc. Makes me wonder where this premium channel series will find an audience.
