Is there leaven in enriched flour?

Leaven is a substance that makes bread rise, typically yeast or sourdough starter.

Enriched flour is simply flour that has been fortified with additional nutrients, such as iron, thiamin, niacin, and riboflavin.

Therefore, enriched flour does not inherently contain leaven. However, it can be used to make bread that requires leaven, such as yeast bread or sourdough bread.

It's important to note that some enriched flour blends may contain additional ingredients, such as baking powder, which acts as a chemical leavening agent. However, this is not inherent to the definition of enriched flour itself.
