Buying canned fish is a sustainable purchase decision. But what is the difference between canned fish “in oil” and “in its own juice”? Let’s explain.

There is hardly anything more sustainable than buying canned fish. In addition, of course, spot fresh eating. Ideally, the fish is caught when it is in season and is immediately preserved and packaged.

Canned fish usually floats in oil: tuna, sardines, anchovies, herring or mackerel. But what does it mean when you say “in your own juice”? For example, tuna meat contains almost no liquid. Therefore, a little water is always added to the cans. Containers must be hermetically sealed and sterilized to ensure a long shelf life. You can do this by heating the canned fish to over 100 degrees Celsius.

More flavor and less calories

“The fish was wiped dry without water,” says Sabine Hülsmann, a food expert at the Bavarian Consumer Advice Center. The statement “in its own juice” is equivalent to the statement “in water” or “soak”. . fewer calories than “tuna oil” to which sunflower oil or olive oil is added.
