If you’ve kept seafood in your freezer, chances are you’ve noticed a bit of freezer burn on it.
But what exactly is freezer burn and how do you know when to toss it out?
What is freezer burn?
Freezer burn is a result of the food sitting too long in the cold environment of your freezer.
When you store food in a freezer, it will continue to freeze until the food reaches 0 degrees Fahrenheit (that’s -18 degrees Celsius).
Once it reaches this temperature, the water inside the food will begin to turn to ice crystals.
The ice crystals form on the surface of the food, creating a thin layer of frost.
This frost creates a barrier between the air around the food and the liquid inside the food, which prevents the food from cooking evenly.
As a result, the food begins to dry out, causing it to shrivel up and shrink.
While the quality of the food isn’t affected, the texture and taste may become tough and unappetizing.
In addition, the moisture content of the food will decrease, making it less nutritious.
What are the signs of freezer burn?
Although there are no hard and fast rules regarding freezer burn, there are certain indicators that indicate whether or not the food is going to be safe to eat.
If your fish looks like this, it probably shouldn’t be eaten:
Thin skinned
Frosted on the outside
Surface appears grayish white or brownish black
Cracked or split
Tough texture
If your fish looks like this, however, you should be able to safely eat it:
Not cracked or split
Not dried out
Not thickened
Not slimy
Not mushy
How does freezer burn occur?
When you store food in a freezer, it’s important to keep the food at temperatures below 0 degrees Fahrenheit.
However, the temperature in the freezer will fluctuate slightly, so sometimes the food will sit above freezing instead of below freezing.
This means that even though the temperature of the food never drops below 0 degrees, it could be frozen for an extended period of time.
The longer the food sits in the freezer, the more likely it is to develop freezer burn.
Once the food starts to thaw, it releases the trapped water molecules back into the surrounding air, allowing them to escape from the food.
The air outside the food then rushes in, causing the food to expand and create more ice crystals.
This process continues until all the water inside the food is replaced by ice crystals.
As the water freezes, it expands, causing the food to shrink.
This shrinking causes cracks and splits in the cell walls, resulting in a tougher texture and reduced nutritional value.
As the water inside the food turns to ice, the food also becomes drier, leading to the formation of mold.
Mold is a sign of spoilage and should be avoided at all costs.
Is freezer burn harmful to consume?
Even though the quality of the food is diminished, it’s still edible.
There are many different types of bacteria that thrive in the cold, including salmonella, listeria, and E. coli.
These bacteria cause illness if consumed, but they’re not harmful if the food is properly cooked.
However, if you notice any signs of spoilage, such as mold or slime, discard the food immediately.
Even though the bacteria aren’t dangerous, they can make you sick if you eat something that’s contaminated.
How can freezer burn be prevented?
There are two main steps you can take to prevent freezer burn from occurring:
Store the food at temperatures below 0 degrees Fahrenheit.
Keep the food moving while it’s stored in the freezer.
What are the best methods for thawing shrimp?
Shrimp is one of the easiest foods to thaw.
All you need to do is place the shrimp in a bowl filled with warm water.
It should start to thaw within 10 minutes.
How can you tell if shrimp has gone bad?
It’s easy to tell when shrimp goes bad.
Here are some signs you should look for:
Discoloration
Mushiness
Odor
Dried out appearance
Hard texture
Slimy texture
Bubbles
Black spots
Off color
Rancid odor
Crusty or chalky residue
Flaky or powdery residue
What are the most common ways to cook shrimp?
You can cook shrimp using a variety of different methods, depending on the type of dish you want to prepare.
You can cook delicious shrimp dishes like Honey Garlic Shrimp, Cream Cheese Shrimp Dip, Vietnamese Shrimp Toast, Cajun Shrimp Pasta,…
These include frying, boiling, broiling, grilling, baking, and roasting.
Frying
To fry shrimp, simply coat each shrimp with flour, season with salt and pepper, and deep-fry the shrimp until golden brown.
Be sure to use oil that is at least 1/4 inch deep in order to avoid burning the shrimp.
Boiling
To boil shrimp, bring 4 quarts of water to a rolling boil and add 2 tablespoons of salt per quart of water.
Add the shrimp and cook for 3 to 5 minutes, depending on the size of the shrimp.
Remove the shrimp from the water and let cool before eating.
Broiling
To broil shrimp, preheat the oven to 400 degrees Farenheit.
Place the shrimp on a wire rack set over a cookie sheet and bake for 7 to 9 minutes, turning halfway through the cooking time.
Remove the shrimp from the oven and serve immediately.
Grilling
To grill shrimp, soak wooden skewers in water for 30 minutes.
Brush the shrimp with olive oil and season with salt and pepper.
Grill the shrimp over medium heat for 6 to 8 minutes, turning once halfway through the cooking time.
Serve immediately.
Baking
To bake shrimp, cut off the heads and tails of the shrimp and remove the shells.
Rinse the shrimp under running water.
Mix together 1 tablespoon of lemon juice, 1/2 teaspoon of garlic powder, 1/2 teaspoon of ground cumin, and 1/4 teaspoon of cayenne pepper.
Season the shrimp with salt and pepper.
Fill the shells with the seasoned shrimp.
Arrange the shrimp in a single layer on a foil-lined baking pan and cook in a 350 degree F oven for 20 minutes.
Turn the shrimp and cook for another 15 minutes.
Roasting
To roast shrimp, rinse the shrimp under running water.
Pat dry with paper towels.
Cut the shrimp in half lengthwise and sprinkle with salt and pepper.
Bake the shrimp for 12 to 15 minutes in a 375 degree F oven.
Serve immediately.
