Should the water in canned tuna fish be a gelatin substance?

Here's why:

* Gelatin is not a natural ingredient in tuna. Gelatin is a protein derived from collagen, typically from animal bones, skin, or connective tissue. It's not present in tuna itself.

* The liquid in canned tuna is usually brine or oil. Brine is saltwater, while oil can be vegetable or olive oil.

* A gelatinous substance in canned tuna could indicate spoilage or contamination. If the liquid has a gelatinous texture, it could be a sign that the tuna has gone bad and should be discarded.

If you see a gelatinous substance in your canned tuna, it's best to err on the side of caution and throw it away.
