The Fish Society | 22.03.2023

Tuna is a popular fish that is often used in sushi and sashimi dishes due to its rich flavor and tender texture. However, if you have purchased super frozen tuna, you may be wondering how to defrost it properly to preserve its taste and texture.

Super frozen tuna is typically stored at temperatures between -60°C and -80°C, which helps to maintain its quality and freshness for a longer period of time. However, this also means that it requires careful thawing to ensure that it remains safe to eat and retains its flavor and texture.


How to defrost super-frozen tuna:

  1. Plan ahead: Super frozen tuna can take several hours to defrost, depending on its size and thickness. It's important to plan ahead and give yourself enough time to defrost the fish properly. Avoid using the microwave or hot water to speed up the process, as this can result in uneven thawing and damage to the fish.
  2. Remove the packaging: Take the super frozen tuna out of its packaging and place it on a plate or tray. This will help to catch any liquid that may be released during the thawing process.
  3. Place in the refrigerator: The best way to defrost super frozen tuna is to place it in the refrigerator. This allows it to thaw slowly and evenly, which helps to preserve its texture and flavor. Place the tuna on the bottom shelf of the fridge, where the temperature is the coldest. For a 1-inch-thick piece of tuna, it may take around 12-24 hours to fully defrost in the refrigerator.
  4. Pat dry: Once the super frozen tuna is fully thawed, remove it from the refrigerator and pat it dry with paper towels. This will remove any excess moisture that may have accumulated during the thawing process.
  5. Use immediately: It's best to use the defrosted tuna immediately after it has been thawed. This will help to ensure that it retains its quality and freshness. If you are not using it immediately, store it in an airtight container in the refrigerator for up to 2 days.

Alternatively, you can place the fish in its packaging under cold water for 10-15 minutes. Enjoy within 24 hours of defrosting using this technique.
