Autolyzed yeast extract is produced by allowing yeast cells to self-digest using their own enzymes. The result is a complex mixture of amino acids, peptides, and nucleotides — particularly glutamates and 5'-nucleotides — that provide a savory, umami flavor profile. It functions as a 'clean label' alternative to monosodium glutamate (MSG) because it provides similar flavor enhancement without requiring MSG declaration.
Enhances savory umami flavor in soups, snack foods, and seasonings without triggering MSG labeling requirements.
Autolyzed yeast extract naturally contains glutamate, the same amino acid in MSG. Individuals who report sensitivity to MSG may experience similar reactions to autolyzed yeast extract. Because it is a natural product, it does not require MSG labeling under FDA rules, which critics argue is a form of deceptive labeling. In 2002, the FDA rejected a petition to require 'contains glutamates' labeling for yeast extracts. It is high in sodium and not suitable for yeast-sensitive individuals.
