How Can Tuna Stay Fresh in Cans While Not Being Refrigerated?

How Can Tuna Stay Fresh in Cans While Not Being Refrigerated?

One of the benefits of FinerFin is how versatile it is. Our products can be enjoyed right out of the can and don’t need to be refrigerated.

In fact, that’s been a selling point for canned tuna for generations. But why can this kind of fish be stored at room temperature and remain fresh for many months and even years?

The answer lies in the processing method.

Processing, Not Preservatives

Many people think that there must be preservatives used in canned tuna to give it its long shelf life, but that’s not the case. No chemicals are added to make sure the tuna doesn’t spoil.

Once canned, the fish is placed in a special cooker that super-heats the cans to a very high temperature under pressure. The tuna ends up vacuum-sealed and sterilized in the can due to this process, and that’s what gives it its shelf life and the ability to remain safe to eat while stored at room temperature.

Refrigerate Tuna Once Opened

You will, however, want to refrigerate any leftovers from your FinerFin product or any other canned tuna you may eat.

You don’t want to leave opened tuna out for more than two hours because that’s when bacteria can begin to form. When refrigerating, use a glass or plastic container with a tight-fitting lid. You do not want to refrigerate the leftovers in the can because it can begin to rust once left open.

Tuna can remain good in the fridge for up to two days if it’s kept in a tightly sealed container.
