Autolyzed yeast extract is a food ingredient or additive that comes as a liquid, paste, powder, or in a granular state. It is used as a flavoring agent or enhancer, and as a firming agent. It comes from yeast that has been specially treated.
Autolyzed yeast is produced by the allowing the peptide bonds of the proteins in the yeast to hydrolyze. This is done by one of two different methods. Edible yeast (cells) are heated under tightly controlled conditions to a temperature that causes proteolytic enzymes already present in the yeast to âdigestâ the proteins, and break their bonds, producing different peptides and amino acids.
