How long does food stay good in the freezer without electricity? – Better

In times of need or disaster, people often turn to their freezers to store what they have.

This includes food and drink, but also clothing, medicine and other items.

But what if the electricity goes out in your home and your freezer keeps getting cold?

Although this may seem like an obvious question, there is no clear answer.

It depends on many factors, including the type of freezer, the temperature outside, the type of food inside, and whether the power outage was short or long.

The best way to find out how long food will keep in an unpowered freezer is to try it for yourself.

We asked several experts for advice on how long certain foods should last in a freezer without electricity.

Here’s what we discovered.


How long does food stay good in a freezer without electricity?

To know how long you can keep food in a freezer without electricity, you need to know the temperature in the freezer and how long it will take for the power to come back on.

The average temperature in a freezer is 0 degrees Celsius (32 degrees Fahrenheit).

A full freezer is -18 degrees Celsius (-0.4 degrees Fahrenheit) while a partially filled freezer is -9 degrees Celsius (-15 degrees Fahrenheit).

Use these two values ​​with the following equation to calculate the shelf life of food in your freezer:

Time = Temperature x Volume

For example, let’s say you have 1/3 gallon of water in your freezer.

If the temperature is 0 degrees Celsius (32 degrees Fahrenheit), the volume of water is 3 liters.

Plug these numbers into the equation above and you get:

Time = Temperature x Volume = 0 x 3 = 0

So according to this formula, the food would be good for zero days.

This means you can theoretically freeze it for up to three years without worrying about spoilage.


Eat

What foods should you not put in the freezer?

Foods with a high moisture content, such as bread, pasta, rice and other cereals, should never be placed in the freezer.

They quickly become soggy and moldy.

Instead, store them in airtight containers.

Liquids should also never end up in a freezer.

They condense on the cold walls and damage the freezer.

Do not put any liquid in your freezer.

Also, don’t put liquid foods in the refrigerator, as the cold air will cause them to puff up and burst.

How long will a freezer keep food frozen without electricity?

A properly functioning freezer will keep its contents frozen indefinitely, even after being turned off.

It depends on the outside temperature, the size of the freezer and how full it is.

When the temperature drops below freezing, the water in the freezer begins to freeze and expand.

As the ice expands, it pushes against the walls of the container.

This creates cracks in the ice.

When the ice reaches a certain point, it breaks up and sinks to the bottom of the freezer.

That’s why it’s important to monitor the temperature of your freezer.

If you notice any cracks, immediately remove all food from the freezer so that it is not damaged.

Is it safe to eat food that has been in the freezer without electricity?

Yes, although it may taste slightly different from usual.

According to the FDA, it is okay to eat food that has been in the freezer without electricity.

However, it is always best to boil it first to kill any bacteria that may have formed during storage.

What should you do with food that has been in the freezer without electricity?

The most important thing to remember is that anything that has leaked to the bottom of the freezer is best thrown away.

Also, don’t touch the leaking ice.

Leave it where it fell and call someone to clean it up.

Once the floors are dry, you can wipe everything down with a bleach solution.

After cleaning, you can put the food back in the freezer.

Be sure to label each container so you know what’s inside.

How long will food stay frozen in a freezer without electricity?

It’s impossible to say exactly how long food will last in a freezer without electricity.

However, it is possible to estimate how long it will take for the food to defrost.

According to the USDA, the ideal temperature in a freezer is between 0 and 2 degrees Celsius (32 and 36 degrees Fahrenheit).

Anything colder will slow the rate of thawing, while higher temperatures will speed it up.

With that in mind, here’s how long it takes to thaw various frozen foods.

  • Meat: one hour per pound
  • Fruit: Five hours per pound
  • Vegetables: Two hours per pound
  • Preserves: three hours per pound
  • Bread: six hours per pound
  • Ice: twenty minutes per liter

If you plan to store food for longer than 24 hours, it is best to pack it in smaller containers.

This reduces the surface area exposed to the air, which reduces the risk of freezer burn.

What can you do to keep food fresh in a freezer without electricity?

There are a few tricks you can use to extend the life of your food in an unpowered freezer.

For starters, you need to make sure that you change your diet regularly.

This ensures that all parts of your food are cooled evenly.

Another tip is to wrap your food tightly in plastic wrap.

This helps prevent condensation on the packaging, helping to preserve the quality of your food.

Finally, you can also use a dehumidifier to humidify your freezer.

This helps to maintain the humidity level in the freezer so food does not dry out.

How do you know if food has been in the freezer for too long without electricity?

There are several ways to tell if your food has gone bad since it went through the freezer.

You can check the date on the package first.

If the expiration date has passed, the food is probably spoiled.

Also watch for signs of mold or mildew growth.

You can also test the food by putting a small piece in a glass of water.

If the food is still edible after 30 minutes, it’s probably good to eat.

However, if it starts to rot within that time, it’s probably ruined.

What can you do to keep food fresh in a freezer without electricity?

As mentioned earlier, rotating your foods is a great way to extend their shelf life.
Another option is to purchase a portable cooler.
These coolers can hold up to 10 liters of water and will keep your food cold for up to 72 hours.
