Sugar Yeast

Yeast is a single-celled microorganism, a type of fungus. It is naturally present in the environment and is used in food production for its ability to ferment sugars. This process creates carbon dioxide and alcohol, which are key to leavening bread and producing alcoholic beverages.

Yeast is primarily used as a leavening agent in baked goods like breads, rolls, and pizza dough, causing them to rise and become airy. It also contributes to the characteristic flavor and aroma of many baked products. Some types of yeast are also used in processed foods as flavor enhancers.

Yeast is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of B vitamins and minerals. While generally considered healthy, some individuals may experience digestive upset from consuming large amounts of yeast, particularly those with compromised immune systems or yeast sensitivities. International bodies like JECFA have evaluated yeast and its components.
