Yellowfin Tuna

< Back

Product Descriptions

Tuna is one of the most highly valued pelagic fish in the world. Tuna presentations range from canned and cold smoked to fresh for cooking and sushi. At Catalina Offshore Products we specialize in fresh and frozen tuna for sushi and cooking applications.

The yellowfin tuna is the most recognized specie, and it is also called "Ahi" yellowfin. It inhabit temperate waters in the Atlantic, Pacific and Indic Oceans.

Japan is the largest market for fresh and frozen tuna, consuming more than 200,000 tons a year. The U.S. , on the other hand, consumes about 55,000 tons of fresh and frozen yellowfin and bigeye.

Yellowfin and bigeye are granded by color and presentation, which can be an objective exercise, as standards can vary from supplier to supplier, depending both upon the experience of the grader and the condition of the market. At Catalina Offshore Products we use the highest standards as most of the costumers are interested in premium sushi grade.

The amount of myoglobin in a tuna's muscle determines its color. The more myoglobin, the redder the flesh. The amount of myoglobin is a function if a tuna's age, physical activity and species.

After the flesh of a tuna is exposed to air, an iron in the myoglobin molecule will start to oxidize, which turns the meat brown. For that reason, it is important to keep tuna loins and steaks wrapped in plastic.

Until recently, frozen tuna had to be held at ultra cold temperatures such as -60F to retard oxidation and prevent the meat from turning brown (brown frozen yellowfin is called "chocolate" tuna). However, exposing red tuna meat to CO2 fix the red color so that tuna held at conventional cold storage temperatures will not turn brown. This "Saku" tuna has been extremely popular and enjoys wide spread use in both conventional and sushi applications.
