What Exactly Is the White Goo?

The good news is that the white substance is a normal byproduct of cooking chicken and is totally harmless. But what exactly is it, and why does it show up?

Researchers in the field of food science have determined that this white goo is actually a mixture of water and proteins that the chicken releases during the cooking process. As the chicken heats up, the muscle fibers in the meat contract, drawing out the liquid inside. When this liquid, which contains proteins like myosin and actin, heats up, it solidifies and forms the white goo. Essentially, it’s a coagulated form of the natural fluids that are present in the chicken.

This process is similar to how egg whites change color and texture when cooked: the proteins in the egg whites undergo denaturation and coagulation, which transforms them from a liquid to a solid.

Why Does the White Goo Appear More in Some Varieties of Chicken?

Interestingly, some types of chicken are more likely to release this white substance than others. The key factors influencing this phenomenon are processing methodsstorage techniques, and the chicken’s previous treatment.

  • Frozen Chicken: The white goo is more common in chicken that has been frozen. Freezing causes the water inside the chicken’s cells to form ice crystals, which damages the muscle structure. As a result, when frozen chicken is cooked, more water and proteins are released than in fresh chicken. The moisture and proteins then coagulate into the white goo during cooking.
  • Storage and Processing: Chicken that has been processed using certain methods (e.g., rapid freezing, packaging with added water or brine) may also have a higher likelihood of releasing more liquid. These chickens tend to have more moisture trapped inside, which can lead to the formation of the goo when they are cooked.
