Why is my stew foaming?

That means the foam will typically appear when making meat-based broths and, to a lesser degree, soups made from high-protein vegetables such as chickpeas and lentils. When those coagulated proteins cluster together, they can create air pockets, which is what causes the “sudsy bubbles,” says Trout.

Should you remove foam from soup?

While the scum can cloud a broth and generally look unappetizing, food scientist Brian Chau of Chau Time assured us that these fats and proteins won't pose any threat to health. “Skimming the scum is not a food safety issue. If there is some scum left over, the soup is still consumable,” Chau said.

Why does meat bubble?

The gas bubbles are composed mainly of Nitrogen, and they develop because the solubility of nitrogen in fat decreases as the fat cools down. The bubbles are not related to microbial growth and are not associated with any aspect of the eating quality or shelf life of the meat.

Should I remove meat foam?

Technically, this is referred to as birefringence. It is caused by the reflectance of light off of muscle proteins, and it is analogous to the color distribution produced by a prism. Muscle proteins are arranged in strands called myofilaments, which are bound together to form myofibrils.

How do you remove foam from cooking?
