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 production, specific strains are cultivated in controlled conditions, often using molasses or grain as a food source.

Why it's used

Yeast is primarily used as a leavening agent in baked goods like bread and pizza dough, causing them to rise and develop a characteristic texture. It also contributes flavor and aroma to foods. It's found in bread, pizza, crackers, and some alcoholic beverages.

Health notes

Yeast is Generally Recognized As Safe (GRAS) by the FDA. It is a source of B vitamins and minerals. JECFA has evaluated yeast and its extracts, and has not set a numeric limit (ADI not specified). Some people may experience digestive upset from consuming large amounts of yeast or yeast extracts, but this is not common at typical dietary levels.

Allergen info

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