What it is

Yeast is a single-celled microorganism, a type of fungus. It is naturally present in the environment and is also cultivated for commercial use. For food, specific strains of yeast are grown in a nutrient-rich liquid medium.

Why it's used

Yeast is primarily used as a leavening agent in baked goods, causing dough to rise and giving bread its characteristic texture and flavor. It is also used in the production of alcoholic beverages and as a flavor enhancer in some savory foods.

Health notes

Yeast is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of B vitamins and protein. International bodies like JECFA have evaluated yeast and its components. Some people may experience digestive upset from consuming large amounts of yeast, though this is uncommon with typical food intake.

Allergen info

Yeast is not one of the 9 FDA major allergens. It does not contain gluten.
