  如果问大家是不是会做饭,我想很多人的回答都是会做的,只不过是做的好坏与否。也有些人认为自己的做饭水平已经十分高超,然而做饭的营养价值却没见有提升,这是为什么呢?都是因为大家在在做饭的时候很容易就犯一些错误。


  蔬菜先切后洗


  洗菜时,切开后的蔬菜与水的接触面积会大大增加,易使B族维生素、维生素C等水溶性维生素和部分矿物质大量流失。正确的做法是先仔细清洗蔬菜,并尽量将水分控干后再切。需要提醒的是,切好的菜最好马上烹调,放置时间不要超过两小时,否则易导致某些营养素的氧化。


  切完菜再用水焯。蔬菜切太碎,容易流失原有的菜香,若再经过水焯,其中的维生素和矿物质会大量损失。所以,焯菜时应尽量让蔬菜保持完整,用水量要多。此外,焯绿叶菜的时候,要加点盐和油,不仅可以防止氧化酶破坏叶绿素,还能保持蔬菜鲜亮的颜色。


  做菜先过油


  做地三鲜、干煸豆角等菜肴时,很多人喜欢先将食材在油里过一下,捞出来再炒,这样做出来的菜色泽明亮、气味香浓。但这种烹调方法会导致摄入的油脂超标,破坏蔬菜本身的营养,同时还可能产生致癌物。建议大家少吃过油菜、煎炸菜,烹调蔬菜多用白灼、清炒、凉拌和清蒸等方式。


  油冒烟了才放菜


  等到油锅冒烟,这样的油温往往已经达到200℃以上,此时才把菜下锅的话,产生的致癌物不仅会增加癌症风险。同时,蔬菜中的营养素也被破坏了。正确的做法是,在油尚未冒烟时,把食材下锅。还有一种简单的测试油温的方法:把竹筷子插入油中,当其四周冒出许多小气泡时,就表示温度足够热,可以下锅了。
