That white stuff you sometimes see coming out of chicken while cooking is usually protein, not something harmful.
🍗 What is it?
It’s mainly albumin, a water-soluble protein naturally present in muscle tissue. As chicken heats up, the proteins contract and can push moisture and dissolved proteins toward the surface. The proteins then coagulate, forming a white, sometimes foamy substance.
You may notice more of it when:
- Cooking chicken at relatively high temperatures
- Using previously frozen chicken
- Cooking chicken breasts, which are relatively lean
- Starting with chicken that contains more retained water
Is it safe?
The white substance itself isn’t a sign that the chicken is spoiled. Food safety depends primarily on the chicken’s internal temperature and handling.
Cook chicken to an internal temperature of 165°F (74°C), measured at the thickest part with a food thermometer.
If the raw chicken has an unusual foul odor, sticky/slimy texture, or other signs of spoilage, don’t rely on cooking to make it safe—discard it.
