切洋葱不会流泪的方法

洋葱是一种常见的廉价家常菜，但切洋葱不是一件简单的事情。很多人都知道洋葱含有一种叫做蒜酶的物质。只要切洋葱，洋葱就会转化成气态化学物质，释放到空气中，让人流泪。我们来看看如何不流泪切洋葱吧！

切洋葱不会流泪的方法

切洋葱为什么会流眼泪？

洋葱中含有一种叫蒜氨酸酶的物质，这种物质平时不能“用完”，但只要把洋葱切开，就会转化成气态化学物质，释放到空气中。当这种化学物质与眼睛接触时，它会刺激人类眼睛角膜中的神经末梢。所以人体通过神经系统命令泪腺分泌眼泪，并洗掉这种刺激性物质。一些科学家认为，洋葱被破坏时产生的刺激性气体是一种自卫行为，会让老鼠和其他吃它的小动物离开。

切洋葱不会流泪的方法

洋葱怎么切丁最简单？

1.洋葱去皮后洗净，从中间纵向切成两半。

2.将洋葱切好的面朝下放在砧板上，水平切洋葱，每刀之间聚集0.3厘米左右，从一端切到另一端0.5厘米左右，不能完全切掉。

3.另一面用手固定，洋葱垂直切开。每把刀之间的距离是0.5厘米。还有，不要完全切开。每把刀之间的距离是距离之前没有切割过的一侧0.5厘米。

4.最后，按住没有用手切掉的那一面，从上到下切掉，就可以得到同样大小的洋葱丁了。

切洋葱不会流泪的方法

1.在流水中切洋葱：在流水中切洋葱，可以控制洋葱中气体的挥发，但是虽然不刺激眼睛，但是浪费水。

2.将洋葱放入冰箱冷藏：将洋葱放入冰箱冷藏，5 ~ 10分钟后取出再次切段。刺鼻的气味会蒸发的更少，再切的时候也不会有眼泪。

3.口香糖：嚼口香糖时，上下颌骨不断开合，会在内部形成负压，通过这个小孔把眼泪吸进嘴里，这样眼睛里就不会有眼泪了，不会有多余的眼泪。

4.咬筷子：切洋葱的时候把筷子横放在嘴里，因为把筷子放在嘴里会干出来，身体会分泌唾液，和切洋葱时流出的眼泪相比，唾液会先流出来。

5.将洋葱放入冷水中浸泡：如果没有进入冰箱，将洋葱的头部和尾部去掉，切成两半，放入冷水中浸泡10分钟。

6.微波加热20秒：切洋葱前，将洋葱放入微波炉中20秒。请用保鲜膜把洋葱包起来，然后加热。据说加热会破坏洋葱中的刺激成分。

7.用护目镜切洋葱：护目镜的闭眼效果更好，这样切洋葱的时候就不会有刺激性物质挥发到眼睛里。

8.用湿刀切洋葱：切的时候，先用水把刀洗干净再切。切洋葱前，最好在菜刀上抹点植物油，以免流泪。

9.在砧板旁边点蜡烛：切洋葱的时候，可以在砧板旁边点蜡烛，减少洋葱的刺鼻气味，效果不错。另外，在案板上放一勺盐切洋葱也不会刺激眼睛。

10.塞纸巾：虽然不优雅，但却是最简单的秘密，因为洋葱中的刺激性成分进入鼻子时会刺激眼睛，塞鼻子可以防止刺激性成分进入体内。
