About Autolyzed yeast extract

Autolyzed yeast extract is a savoury ingredient made by allowing yeast cells to break down through their own enzymes, then collecting the soluble material. It is typically brown or tan and may be supplied as a paste, liquid or dried powder. Its flavour is deeply savoury, often described as yeasty or umami-like.

It is used in small amounts to add savoury depth to soups, sauces, seasonings and other prepared foods. Commercial extracts vary by yeast source, processing and formulation, and products may contain carriers or other added ingredients. It is a processed extract rather than intact yeast, so a product label is needed to establish its exact composition.
