What it is

Yeast is a single-celled microorganism used in baking and fermentation. Citric acid is a weak organic acid naturally found in citrus fruits like lemons and limes. It is also produced commercially through the fermentation of sugar by certain types of yeast.

Why it's used

Yeast is often used as a leavening agent in baked goods, causing dough to rise. Citric acid is commonly used as a flavoring agent and preservative in foods and beverages, providing a tart taste and preventing spoilage. They can appear together in processed foods for flavor and texture.

Health notes

Yeast and citric acid are generally recognized as safe (GRAS) by the FDA when used in food. Citric acid is a common dietary component and is metabolized by the body. JECFA and EFSA have evaluated citric acid and found it to be safe for consumption. No significant health concerns are associated with the typical consumption of these ingredients.

Allergen info

Neither yeast nor citric acid are among the FDA's nine major allergens. Citric acid is not a source of gluten.
