What it is

Yeast is a single-celled microorganism, a type of fungus. It is commonly grown on molasses or grain-based media. For food use, yeast is typically dried and sold in packets.

Why it's used

Yeast is primarily used as a leavening agent in baked goods. It consumes sugars and produces carbon dioxide gas, which causes dough to rise and gives bread and other baked items their characteristic texture. It is found in bread mixes, pizza doughs, and other baked goods.

Health notes

Yeast is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of B vitamins and minerals. International bodies like JECFA and EFSA have evaluated yeast and its components. At typical consumption levels in food, it is not associated with adverse health effects.

Allergen info

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