What is Ahi tuna?

Ahi tuna is a type of tuna (fish) called Kihada in Japan. It is called Ahi in Hawaiian as it refers to the 2 species called the yellowfin tuna and the bigeye tuna. The yellowfin tuna has soft dorsal and anal fins and finlets that are yellow in color. The yellowfish tuna is thinner in mass when compared to the bigeye tuna.

The yellowfin tuna has coloration on its flesh and ranges from pink when it is young and develops into red color as it grows. The older fishes are better as the fat content is higher and the meat/flesh is tastier. 

The Ahi tuna has a lot of nutritional benefits as well as they are known to have high levels of niacin, Vitamin B, magnesium, phosphorus, and omega-3 (DHA & EPA). For more information about the nutritional component, please click here.

It is commonly served as sushi, sashimi, cooked-rare, or medium-rare. The best way to cook the ahi tuna is to either grill, pan-fry or pan-sear the fish.

How does the refrigeration method for defrosting ahi tuna work?

The refrigeration method is the traditional method where the packaged (vacuum or tightly) ahi tuna is removed from the packaging and placed on a plate or container and put on the lower shelf of the refrigerator at 41℉.

Removing the packaging material is very important as during defrosting the ahi tuna might have growth of food-borne pathogens like Listeria monocytogenes or Clostridium botulinum. The time required for the defrosting depends on the size/thickness of the fish meat. An average ahi tuna steak will take approximately 8-12 hours to defrost in the refrigerator at 41℉.

The fish before defrosting should be placed in a container lined with parchment paper or paper towels and can be covered with plastic wrap. The disadvantage of this method is that it takes a lot of time for defrosting and has to be planned one day in advance.

Is the cold water method suitable for ahi tuna defrosting?

The cold water method is the most sought-after method for the defrosting of ahi tuna. The frozen ahi tuna has to be removed from the packaging and put in a ziplock cover that will not allow water to seep into it. For defrosting the ahi tuna, a large pot or the sink can be used with water-filled water until the top. 

The ziplock containing the ahi tuna should be immersed in a large pot of water or the kitchen sink and has to be stirred occasionally. It takes about 30 minutes to defrost 1 pound of ahi tuna and based on the weight, the water has to be changed every 30 minutes.

For example, if the weight of the ahi tuna is 3 pounds, it will take 1.5 hours and the water needs to be changed every 30 minutes. With this method, the tuna can also be stored for up to 2 days in the refrigerator with proper packaging.

How does the microwave method of defrosting ahi tuna work?

The microwave method of defrosting ahi tuna is the easiest and quickest way of defrosting and does not require any planning and can be done instantly. In this method, the ahi tuna has to be removed from the packaging and placed in a microwave-safe container or bag.

The mode of the microwave can be changed to the defrost mode or use the 30% power setting. The time on the microwave can be set to 2.5 minutes. After this, the ahi tuna has to be flipped and microwaved for another 2.5 minutes. 

On completion of one cycle, the ahi tuna can be checked if it has been fully defrosted or it can be further microwaved for 30 seconds on either side until completely defrosted. The disadvantage of this method is that the ahi tuna has to be cooked immediately and cannot be stored in the refrigerator. 

What not to do when defrosting ahi tuna?

The things or methods not to employ while defrosting ahi tuna are not to use hot water or let the ahi tuna rest on the kitchen platform to defrost. These methods are dangerous as there might be microorganisms that will grow on the surface of ahi tuna and make it harmful for the humans consuming it.
