What it is

Yeast soda, also known as yeast extract, is a flavoring ingredient made from yeast. The yeast cells are broken open, and their contents are concentrated and often pasteurized. It has a savory, umami flavor similar to soy sauce or mushrooms.

Why it's used

Yeast extract is used as a flavor enhancer, adding a savory or umami taste to foods. It is commonly found in savory snacks like popcorn and peanuts, as well as in ice cream and frozen yogurt for a unique flavor profile. Manufacturers use it to boost the overall taste of a product.

Health notes

Yeast extract is generally recognized as safe (GRAS) by the FDA. It is a source of B vitamins and amino acids. International bodies like JECFA have evaluated yeast extract. While generally considered safe, some individuals may be sensitive to its naturally occurring glutamates.

Allergen info

Yeast extract is not derived from any of the 9 FDA major allergens. It does not contain gluten.
