The first time I cooked chicken by boiling it, I panicked when a white foam began to form at the top of the pot.
I recall looking at it, thinking that either the meat was bad or, worse yet, had been cooked in some sort of chemical compound. I almost threw the entire pot away.
It turns out, however, this is a very common reaction. If you’ve ever thought to yourself, “Why does chicken foam when I am cooking it?” you’re most certainly not alone. Fortunately, the white foam is typically nothing to be concerned about.
What Is That White Foam on Chicken?
When I first saw the white foam, I thought it looked a little gross, similar to dish soap or cloudy goo. However, after researching it, I realized it’s much more normal than it seems. The white foam that forms when boiling or simmering chicken is primarily made up of denatured proteins. Specifically, it contains a type of protein called albumin.
When chicken is heated, these proteins unwind and rise to the top of the liquid, forming the bubbly and frothy appearance of the foam. In addition to proteins, there are some fats and naturally occurring impurities that mix into the foam. These items were simply present in the meat and bones.
Since this occurs more noticeably during boiling due to the constant motion of the water forcing everything to the surface, if you notice chicken foam while boiling, it’s okay to relax. It is not chemicals; it is simply the result of scientific processes taking place.
