Tuna

What Is Tuna?

Tuna is a large and powerful migratory fish from the mackerel family (scombridae) that lives in schools in open seas; several related species are referred to under the name "tuna," primarily bluefin tuna (Thunnus thynnus). Its fresh form is known for its dark red, dense-textured flesh.

Although it is consumed mostly canned worldwide, it is also a sought-after fish in fresh slice form, especially in sushi/sashimi and grilled recipes.

Nutritional Values of Tuna

100 grams of raw tuna contains approximately 144 kcal of energy and around 23 g of protein; its fat content is moderate. It is especially rich in vitamin B12, and also contains selenium and niacin.

What Are the Benefits of Tuna?

With its high protein and vitamin B12 content, tuna is one of the fish that stand out as part of a balanced diet; it is also valuable for its omega-3 fatty acids. Since it is a large, long-lived fish, careful consumption is recommended due to mercury accumulation.

This information is general; tuna is a food, not a substitute for medical treatment. Consulting a specialist about consumption amounts during pregnancy and for children is recommended.

How to Choose Tuna?

In fresh tuna slices, the color should be dark red and glossy; parts that have turned brown are a sign of spoilage.

• The surface should be moist and shiny, not dry/dull looking.
• The smell should be a light sea scent, not a sharp ammonia odor.
• When the flesh is pressed, it should be firm and elastic.

How to Store Tuna?

A fresh tuna slice stays fresh in the refrigerator for at most 1 day; it can be stored tightly wrapped in the freezer for a few months. Canned tuna should be consumed within 1-2 days once opened, kept in a separate container in the refrigerator.

Using Tuna in the Kitchen

Fresh tuna is usually cooked briefly on the grill or used raw in sushi/tartare; the canned form is used in salads, sandwiches, and pasta.

How Is Grilled Tuna Cooked?

A thick slice of tuna is rubbed with olive oil and spices, then cooked briefly on a very hot grill for 1-2 minutes per side; keeping the center rare prevents the flesh from drying out.

Which Recipes Use Tuna?

Grilled tuna, tuna salad, tuna pasta, and tuna sandwich are the best-known recipes.
