为什么要对食物进行加工呢?或蒸,或炒,或榨,或煎,或煮。



我们不说为了好吃,那不是最必要的。除了消毒之外,有一个主要目的,是为了把食物的细胞壁破了,容易为人体吸收。那么为什么不都简单地榨一下搅烂了就能吃了呢?因为一般食物做完了,还不能马上吃,总得放一会儿。那么最好的办法是把细胞壁破了以后再封上,等吃的时候就容易了。

这就是厨师的功夫所在了,不然人人都可以当厨师了。这里面包括食物的搭配技巧,但还不是主要的。主要的是要控制好火候,不能做得不熟,也不能太过。所谓熟不熟,就是判断是否把食物很好地均匀地处理了,以便容易消耗吸收。

熟得正好的食物往往是流出了里面的汁,但还是新鲜的。因为如果细胞壁破得太久了,元气都走掉了,也就没有营养了。所以煲汤的好处是把食物中的元气溶解到汤里,这样既不容易丢失,也容易被人吃下去。而好的食物煮出来以后的汁都在碗里,一点都不浪费。

而对于猛火炒的食物也是同样道理,先用刀工把食物切碎,然后加油用大火把细胞封上,等到吃的时候才流汤,就全吃进去了。这个道理从很多实践中可以看得出来的,有的人炒菜炒出好对水来,再把水倒掉,那么就什么营养也没有了,只剩下细胞壁了。
