That white slimy stuff is called albumin, and it's actually just a harmless (albeit pretty gross-looking) protein that solidifies as salmon cooks.
That white gunk seeping from your salmon is called albumin. It's a protein—not fat—that pushes to the surface of the fish when you heat it. "Once this protein reaches temperatures between 140 and 150 degrees, its moisture is squeezed out, and it congeals and turns white," according to America's Test Kitchen.
Originally Answered: When cooking fish, why it creates that foam on top? It's fish proteins dissolved in the water. The proteins become denatured, forming long chains that in turn form a surface on the water. That surface is broken into bubbles by the steam coming from the water.
Short answer: albumin. It's a liquid protein hidden inside the fish when it's raw. It coagulates and moves to the surface as the meat cooks.
The white stuff on salmon is perfectly normal
According to her, “It's nothing to be scared of and it's totally safe to eat, but I think we would all admit—it's nasty.” When salmon is raw, you can't see the albumin inside—but as the fish cooks, it thickens and forms the gooey white stuff you see on salmon skin.

Albumin is a protein that exists in the fish in liquid form when it's raw, but coagulates and becomes semi-solid when you subject the salmon to heat, whether that's in the oven, on the stove, or on the grill.
Other names for these threadlike nematodes are herring worms, cod worms and seal worms. Freshwater perch, trout, and salmon (that spend part of their life in freshwater), may carry the tapeworm larvae of Diphyllobothrium. These worms are grey-white, with a soft flabby appearance.
We often get the question, “Are fish skins safe to eat?” The quick answer, yes.
It's albumen. Albumin is a protein that comes out of the fish as it cooks, coagulating on the surface.
First, brine the raw fish (5 tablespoons of table salt dissolved in 2 quarts of water) for 15 minutes. This will not only reduce the presence of albumin but also season the flesh and help prevent it from drying out as it cooks. Second, swab the puncture site with a paper towel before continuing to cook the fish.
Protein foam is the result of organic waste (feces, dead fish, and uneaten food) forming an oxygen-trapping surface film that creates small air bubbles that stick together and form a smelly foam. It is more prevalent in saltwater aquariums but is seen occasionally in freshwater tanks as well.
This is normal when an aquarium is first set up. It is referred to as a bacteria bloom. The cloudiness should be gone within anywhere from two days to a couple of weeks. You can do a 10 to 15 percent partial water change and gravel vacuuming after a week to speed it up.
Dry skin on the legs that looks like snakeskin, or resembles alligator skin, can be attached to a condition called ichthyosis. There are over 20 different kinds of ichthyosis, and it's generally attached to a layer of the skin which is unable to retain moisture.
Fish skin is generally safe to eat as long as it has been cleaned thoroughly and the outer scales have been removed. Fish skin is rich in nutrients such as protein, omega-3 fatty acids, and vitamin E, which can help with muscle growth, heart health, and skin health.
While the health risk of eating raw fish is minimal for most healthy people, it can be serious for others. Foodborne illnesses in people who are healthy can be gross — vomiting, diarrhea, fever and abdominal pain are common.
Parasites - Anisakiasis
Anisakiasis is a parasitic disease caused by anisakid nematodes (worms) that can invade the stomach wall or intestine of humans. The transmission of this disease occurs when infective larvae are ingested from fish or squid that humans eat raw or undercooked.
Are There Parasites in All Fish? Every kind of wild-caught fish can contain nematodes. One study found that more than 90% of certain types of wild-caught fish were infected with nematode larvae. Another concluded that one type of worm infecting fish around the globe is now 283 times more abundant than in the 1970s.
Fish infected with Diphyllobothrium larvae may be transported to and consumed in any area of the world. Adequately freezing or cooking fish will kill the parasite.
The short answer is yes. Salmon is a great source of omega-3 fatty acids, which support the immune system, may decrease inflammation, and can keep your dog's coat looking shiny and healthy. Along with some other types of fish, salmon is also a good protein source.
Can you eat raw salmon? The straight answer. Yes. Raw salmon is a popular ingredient in many dishes all over the world — sushi, for example, is notable for its raw salmon offerings like sashimi.
Salmon that is old or spoiled will look dull or gray and may have a white, filmy residue. In addition, it will have fishy or ammonia-like odor and a mushy or slimy texture.
This gray portion of the salmon is a layer of fatty muscle tissue that is low in the pink pigments found in the rest of the fish. This area contains more fat than the rest of the salmon—and it therefore is the most rich in omega-3 fatty acids, since salmon fat is high in omega-3s.
Yes, you can eat salmon skin. In fact, when cooked properly, salmon skin has a crispy, salty bite. However, before chowing down, it's important to take a few precautions. Depending on where your fish came from, it may contain environmental toxins.
