If you have recently purchased some tuna or a store has it on sale you might be wondering if it’s possible to freeze some excess tuna that you have. You certainly don’t want it going bad but will it still taste alright after being frozen? 

After you have purchased your tuna, whether it’s raw, cooked, or canned you may be wondering if you can pop it into the freezer until you need to use it. 

The good news is tuna can be frozen. Tuna is a great fish to freeze and it can be frozen for around 3 months.

Can You Freeze Tuna?

Keep in mind though that freezing a fresh tuna is not like just freezing a casserole or soup. Fresh tuna must be frozen carefully to avoid freezer burn. 

Tuna that is not properly frozen can develop a foul taste and smell. Taking the time to properly freeze tuna will result in tuna that is free of bacteria and cooks properly when thawed. 

Improperly frozen tuna can also carry disease and cause illness. Taking the time to properly freeze tuna will result in tuna that is free of bacteria and cooks properly when thawed. 

The good news is that it only takes a few ingredients to preserve the freshness of the tuna while in the freezer.

You will need water, pickling salt, plastic wrap and a resealable plastic freezer bag. Prepare a solution of salt and water. Submerge the tuna into the water and hold for 1 minute. 

The solution of salt and water will prevent the moisture from leaving the tuna, and will also help the tuna stay firm. Pat the tuna dry. This will ensure crystals don’t form on the fish. 

Then wrap the tuna several times around tightly in plastic wrap. Wrap each piece of fish separately. 

The next step is to place the tuna in a resealable plastic freezer bag. Make sure to press all the air out of the bag and then label the bag with the date. Place the tuna in the coldest part of your freezer.

The tuna should be kept at a constant temperature of 0 degrees Fahrenheit. This may be hard to do if you use the freezer attached to your refrigerator. 

Most families will open and close the freezer several times a day. It’s best if you have a deep freezer where the temperature can stay constant all the time.

If you follow these steps you can keep the tuna in your freezer for months, although it will be freshest if used between 2 and 3 months. After 2 -3 months the tuna may start to separate and the fish may lose some of its taste and become bland. For best results, do not refreeze tuna after thawing.

Another way to freeze your tuna is to freeze it in a block of ice. Fill a pan with water and place your tuna in the water, then place the pan in the freezer. Once the water is frozen, remove the block of ice from the pan. 

Wrap the block of ice with moisture proof packaging.

To thaw the tuna, defrost the frozen tuna in your refrigerator. This will help you avoid contamination or spoilage. Do not defrost frozen tuna at room temperature, in a microwave or under hot water. 

It will take about 5 – 6 hours to thaw a large tuna. It will take around 2-3 hours to thaw a small tuna.

Tuna Preparation

Tuna is a saltwater fish that belongs to a subgroup of the Mackerel family. Tuna is widely, but sparsely distributed throughout the oceans of the world. Tuna is also an important fish for commercial fishermen.

The fresh flesh of tuna is widely regarded as a delicacy in most areas where it is shipped, being prepared in a variety of ways. When served as a steak, the meat of most species is known for its thickness and tough texture. 

In the United Kingdom supermarkets began flying in fresh tuna steaks in the late 1990s, which helped to increase the popularity of using fresh tuna in cooking. By 2009, celebrity chefs regularly featured fresh tuna in salads, wraps, and char-grilled dishes.

Various species of tuna are often served raw in Japanese cuisine as sushi or sashimi.

Tuna is also canned in edible oils, in brine, in water, and in various sauces. Tuna may be processed and labeled as “solid”, “chunked” (“chunk”) or “flaked”. When tuna is canned and packaged for sale, the product is sometimes called tuna fish. 

As tunas are often caught far from where they are processed, poor interim conservation can lead to spoilage. Tuna is typically gutted by hand, and later precooked for prescribed times of 45 minutes to three hours. 

The fish are then cleaned and filleted, canned (and sealed), The sealed can is then heated under pressure for 2 to 4 hours. This process kills any bacteria, but retains the histamine that may have been produced by those bacteria, and so may still taste spoiled. 

The international standard sets the maximum histamine level at 200 milligrams per kilogram.
