Freezer burn changes the composition of your food, resulting in off flavors, textures, and colors.

冷冻品再烧制会改变食物的成分，导致口味、质地和颜色的改变。

What's more, freezer burn isn't just limited to freezers, it happens in nature, too.

另外，冻伤不只发生在冰箱冷冻库，也发生在自然环境中。

If so, that's freezer burn, and it may have been cooked before it hit the freezer.

如果有的话，那就是冷冻品再烹制的，这道菜可能在放入冷冻室之前就已经做熟了。

That's why freezer burn happens less to flour and nuts than to vegetables and meat and ice cream, which contain more water.

这就是为什么冻伤发生在面粉和坚果上的机率比蔬菜、肉类、冰激凌这些含水量多的食物要小。

Anyone who has prepared a frozen dinner can easily attest to the flavors of freezer burn; they can also detect it when a restaurant serves it.

任何准备过冷冻晚餐的人都能轻松地察觉出冷冻品烧熟的味道；当餐厅提供的是冷冻食品时，他们也能察觉到这种味道。

Now we're just gonna cover this, with a little plastic wrap over the top, so that we don't get any like freezer burn, or anything like that.

现在我们要把它盖起来， 在上面盖上一点保鲜膜，这样我们就不会被冻伤，或类似的东西。

This is freezer burn, and it happens because ice in the frozen food sublimates — that is, the water changes directly from a solid to a gas rather than first melting and then evaporating.

这就是冷冻烧伤，这种情况发生是因为冰在冷冻的食物上升华，更确切地说，是冰冻的水直接从固态变为气态，而不是先融化再蒸发。

So freezer burn is what happens if you leave something in your freezer for a very, very, very, very long time, let's say a pack of peas, you leave them there.

所以冷冻灼伤是指如果你把某样东西放在冰箱里很长时间，比如一包豌豆，你把它们放在那里。

And you notice the little icicles start forming around the pack of peas, and you take them out and you have to like wash off or wipe off all of the freezer burn.

你注意到小冰柱开始在豌豆包周围形成，你把它们拿出来，你必须喜欢洗掉或擦掉所有的冷冻烧伤。

Unlike regular frost (also called " hoar frost" ) , which forms when water vapor that's already in the air freezes into crystals on top of something cold, the frost in freezer burn comes from frozen water in the food itself.

不像常规的霜 (或者叫白霜)，由水蒸发形成，在某个暴露于空气的低温物体表面冻结成晶体，冻伤中的冰霜来自食物内部冻结的水份。
