特百惠硬币的技巧：一个简单的黑客，知道您的食物在停电后是否仍然安全

当我出去延长旅行或冒险时，我通常会发现清理冰箱的好时机。但是，有时很难预测将剩下多少食物

I usually find that when I head out for an extended trip or adventure, it’s a great time to also clean out my fridge. However, sometimes it’s difficult to predict how much food I’ll have left over, so sometimes some vegetables or drinks will still be left inside. One of my biggest concerns is how do I know if it’s all safe by the time I return?

我通常会发现，当我出去延长旅行或冒险时，这是一个清理冰箱的好时机。但是，有时很难预测我要剩下的食物，因此有时仍然会留下一些蔬菜或饮料。我最大的担忧之一是我如何知道我返回时是否安全？

The FDA says frozen food can stay safe for up to 48 hours in a full freezer or 24 hours in a half-full one during a power outage, as long as the door remains closed. After that, bacteria can grow after your food is above 40 degrees Fahrenheit for over two hours. It’s often hard to know how long an outage might have lasted unless you’re great friends with your neighbor.

FDA表示，只要门关闭，冷冻食品就可以在全冷冻室中保持安全长达48小时，或者在半场中的24小时保持安全性。之后，在您的食物超过40摄氏度后，细菌可以生长两个多小时。除非您是与邻居的好朋友，否则通常很难知道停电可能会持续多久。

So, here’s a coin trick that I learned from one of my own neighbors.

因此，这是我从一个邻居中学到的硬币技巧。

This trick is just as simple as it sounds. Take a small cup or Tupperware container that will fit comfortably in your freezer and fill it about three-fourths of the way with ice. It’ll take a few hours until it’s frozen, depending on the size of your container, but once the block is solid, set a quarter or any other coin on top of it and return the container to the freezer.

这个技巧听起来很简单。乘坐一个小杯子或大型机器容器，该容器将舒适地放入冰箱中，并用冰填充约四分之三的冰箱。根据您的容器的大小，将需要几个小时才能冷冻，但是一旦块固体，将四分之一或其他任何硬币设置在其顶部，然后将容器返回到冰箱中。

A properly functioning freezer keeps a temperature of about 0 degrees, which keeps everything from ice cream to raw chicken safely frozen. If the power stays on, the ice in your container won’તી melt, and the quarter will still sit on top of the ice block when you return.

正常运行的冰箱可保持大约0度的温度，从而使从冰淇淋到生鸡都可以安全冷冻所有东西。如果电源持续下去，您的集装箱中的冰将融化，当您返回时，该季度仍将位于冰块的顶部。

That said, if the power cuts out for an extended period, the freezer will lose its chill, and the ice will melt, letting the quarter sink into the bottom of the Tupperware. It’s also important to note that the placement of your Tupperware matters. When placed towards the door, there is a higher chance of it melting, while if you stash it in the back, the ice might not melt as much. I’d choose a happy medium.

也就是说，如果电源很长时间，冰柜将失去寒意，冰将融化，使四分之一沉入特百惠的底部。同样重要的是要注意，特百惠的放置很重要。当朝门放置时，它会熔化的可能性更高，而如果将其存放在后面，则冰可能不会太多。我会选择一个快乐的媒介。

This is a great hack because there have been plenty of times when I might not have known the difference, increasing the risk for food-borne illness at my house. While it’s not perfect because I can’t say when or how long the freezer was out, I’ll at least have a hint about the situation of the house while we were away.

这是一个很棒的骇客，因为有很多次我可能不知道这种差异，从而增加了我家中食源性疾病的风险。虽然这并不完美，因为我不能说冰柜何时或多长时间，但我至少在我们不在时对房子的情况有一个暗示。

Ever since implementing this hack, I’ve been able to eat with confidence that my food hasn’t been sitting out in the warmth. Of course, it’s always best to use your best judgment, even if the quarter didn’તી sink. If your food is smelly, looks soggy from ice melt, or if you see new scores of freezer burn, this could be another sign that your food isn’t as safe as you thought it was, and you’re better off tossing the lot.

自从实施这种黑客以来，我就能够确信自己的食物一直没有温暖。当然，即使季度没有下沉，也总是最好使用您的最佳判断。如果您的食物臭味，从冰融化中看起来湿润，或者如果您看到新的冰柜燃烧，这可能是另一个迹象表明您的食物并不像您想象的那样安全，最好不要扔掉很多东西。
