Yeast Extract

Alternate Names

Hydrolyzed Yeast, Autolyzed Yeast, Baker's Yeast Extract

Description

Yeast extract is a term used to describe a few different processed yeast products. Autolyzed yeast is made up of yeast cells that are allowed to die and break up releasing enzymes that will break down their proteins into simpler compounds such as glutamate. Hydrolyzed yeast results in the same thing; it just uses an outside source of enzymes for the break down. These freed compounds are one of the main ways we produce glutamate for MSG.
