Yeast Extract

Yeast extract is a flavor enhancer made from yeast cells. It is produced by breaking down yeast cells, often baker's or brewer's yeast, into their components, which results in a savory paste or powder.

Manufacturers add yeast extract to foods to boost savory flavors, often described as umami. It is commonly found in snacks like chips, sauces, soups, broths, and processed meat alternatives.

The U.S. Food and Drug Administration (FDA) considers yeast extract to be Generally Recognized As Safe (GRAS). Yeast extract naturally contains glutamates, which are the same compounds responsible for the savory taste of monosodium glutamate (MSG). While some people report sensitivity to MSG, scientific reviews have not found consistent evidence that naturally occurring glutamates in foods like yeast extract cause adverse reactions in the general population. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated yeast extract and determined that an acceptable daily intake (ADI) does not need to be specified, meaning it is considered safe at levels typically consumed.
