What it is

Yeast is a single-celled microorganism, a type of fungus. It is commonly grown on sugar-rich media, such as molasses. The yeast is then harvested, washed, and dried for use in food products.

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 and volume. It is found in bread mixes, pizza mixes, and other baked good mixes.

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. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated yeast and found no safety concerns. There are no widespread controversies regarding its consumption at typical levels.

Allergen info

Yeast is not one of the nine major allergens recognized by the FDA. It does not contain gluten.
