What is Yeast Extract?
Yeast extract is a food flavoring made from the same yeast used to make bread and beer. It’s also added to some foods like soy sauce and cheese for a savory flavor. The taste they create is sometimes referred to as “umami.” Yeast extract is also found in canned soups and stews, frozen dinners, and salty snacks.
Yeast extract is made by adding sugar to yeast in a warm environment. As the yeast expands, the walls of its cells soften. This mixture is then spun in a centrifuge and the loosened cell walls are whisked away. There are two kinds of yeast extract, autolyzed and hydrolyzed. In both, the cell walls are discarded and the contents of the cell are combined. In autolyzed yeast, the enzymes found in the yeast itself are used to break down the proteins. In hydrolyzed yeast, these enzymes are added to the yeast. Yeast extract can be found as a thick gel or in a moist powdered form.

I Heart Keto Mart Rating Guide
I Heart Keto Mart rates all ingredients through a “keto diet” & “low carb diet” lens. As an example, peas would be rated as “Acceptable” on a non-keto healthy diet; however, due to their carbohydrate level, we rate them “Objectionable”. We also rate all sweeteners that typically cause a rise in blood sugar and insulin levels as “Objectionable”. If you prefer a natural sweetener, like honey, over a sugar alcohol like erythritol, you may not agree with our “Objectionable” rating. I Heart Keto Mart rates all ingredients based first and foremost for those that have a sugar/carbohydrate addiction. Ingredients are rated for those who must moderate if not completely abstain from any sugars. If you have questions about this, please refer to this article: Why Some Whole Foods Are Not Keto Friendly
