What is canned tuna ?

Canned tuna is made by steaming tuna or bonito, preserving it in oil or water, then canning it. It comes in various forms, such as in blocks, chunks that are convenient to cook with, and flakes that can be sprinkled directly on salads, etc. The umami in fish meat and its plain flavor make it great for various cooking such as salads, sushi, simmered dishes, stir-fries, and more. Canned tuna is not limited to just Japanese cuisine. It is used in Western cuisine and many other dishes as well! Generally salt is added to tuna, but there are also varieties with no salt added or flavored with other seasonings.

Nutrition facts

Canned tuna is rich in protein and iron but low in fat. It is also packed with DHA and EPA which is known to help improve blood flow and support blood vessel health. Tuna preserved in water is lower in calories than that in oil.

How to storage: not to waste the ingredient

Just like other canned foods, canned tuna can be stored for a long time at room temperature before opening. After opening, canned tuna can be transferred to a storage container and refrigerated for 2 to 3 days, or frozen for about 1 month.


Canned tuna has a plain flavor much like chicken, making it a great alternative for chicken. Steamed tuna preserved in water has approximately the same calories and protein content as chicken tenderloin.
