First, I discovered that the yellow tint is often attributed to oxidized fat. Salmon is a naturally fatty fish, which is one of the reasons it tastes so rich and succulent. But sometimes, when frozen for long periods or improperly stored, the fat can oxidize and change color. It’s a lot like what happens when you leave an apple slice out in the open for too long and it starts to turn brown.
This oxidation doesn’t necessarily mean the salmon is bad or unsafe to eat. It’s more about the quality and appearance. Of course, you’ll want to ensure the fish doesn’t have any other signs of spoilage like a sour smell, slimy texture, or an off-putting taste, which are all indicators that the fish might not be safe.
Improper Packaging and Freezer Burn
Freezer burn is another culprit. If the salmon isn’t properly sealed or protected in the freezer, it can lose moisture and develop discoloration, sometimes manifesting as a yellow or white spot. It’s a little disheartening to see your favorite fillet with freezer burn, but again, it’s not the end of the world. You can trim off the affected area, and the remaining salmon is usually perfectly fine to cook and eat.
