What it is

Yeast is a single-celled microorganism, a type of fungus. It is naturally present in the environment and on plant surfaces. For food use, specific strains are cultivated in controlled conditions, often grown on molasses or grain-based media.

Why it's used

Yeast is primarily used as a leavening agent in baked goods like breads and pastries. It consumes sugars and produces carbon dioxide gas, which causes dough to rise. It also contributes to the flavor and texture of many foods.

Health notes

Yeast is generally recognized as safe (GRAS) by the FDA for food use. It is a source of B vitamins and minerals. International bodies like JECFA have evaluated yeast and its components. While generally safe, some individuals may experience digestive upset from large amounts of yeast, particularly those with compromised immune systems.

Allergen info

Yeast is not one of the 9 FDA major allergens. It does not contain gluten unless it is grown on a gluten-containing medium and not sufficiently purified, which is uncommon for food-grade yeast.
