What it is

Yeast is a single-celled microorganism, a type of fungus. It is naturally present in the environment and on plant matter. 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 pizzas, producing carbon dioxide gas that makes dough rise. It also contributes to the characteristic flavor and aroma of many fermented foods. Some yeast extracts are used as flavor enhancers.

Health notes

Yeast is generally recognized as safe (GRAS) by the FDA for food use. It is a source of B vitamins and minerals. While generally considered safe, some individuals may experience digestive upset from high yeast intake. International bodies like JECFA have evaluated yeast and its components.

Allergen info

Yeast itself is not one of the nine major allergens. However, some yeast is grown on or may contain traces of gluten-containing grains like wheat or barley, which could be a concern for individuals with celiac disease or gluten sensitivity.
