What is Autolyzed Yeast Extract?

Autolyzed yeast extract is a food ingredient made from yeast, usually Saccharomyces cerevisiae, where the cell walls of the yeast are broken down using their own enzymes (autolysis). This process results in a paste full of amino acids, peptides, and other components that contribute to its unique flavor profile.

It is primarily used as a flavor enhancer, imparting a savory, umami taste to foods, similar to monosodium glutamate (MSG) but with a distinct composition. Despite its flavor-enhancing qualities, some individuals may avoid it due to concerns about its similarity to MSG, although the two are chemically different. The evidence regarding any negative health effects of consuming autolyzed yeast extract is not conclusive.

On labels, autolyzed yeast extract indicates the presence of free glutamates, which some people may prefer to avoid. It is generally regarded as safe by food safety authorities around the world.
