What is Yeast Extract?

Yeast extract is a flavoring ingredient derived from yeast, used notably in processed foods. It is made by breaking down yeast cells using enzymes, resulting in a paste-like substance rich in umami flavor due to its high glutamate content.

Yeast extract is used primarily to enhance flavor in savory foods such as soups, sauces, and snacks. While some people may associate it with MSG (monosodium glutamate), which sometimes causes sensitivity, yeast extract is considered a natural source of glutamates. The health effects are largely considered similar to other natural glutamate sources.

When you see yeast extract on a label, it is usually included to boost the savory taste of the product without using artificial flavor enhancers. It is not known to cause adverse health effects in most people.

Commonly found in: snacks, soups, sauces, processed foods, spreads
