Dried Sourdough

Dried sourdough is a dehydrated form of sourdough starter, which is a culture of wild yeasts and bacteria. It is made by carefully drying a mature sourdough starter, often using methods like spray-drying or freeze-drying. This process preserves the microorganisms and the characteristic tangy flavor of sourdough.

Manufacturers use dried sourdough primarily as a leavening agent and flavor enhancer in baked goods. It contributes a complex, tangy taste and can help improve the texture and shelf life of products like breads, pizzas, and crackers. It is a convenient alternative to maintaining a live sourdough starter.

Dried sourdough is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural product of fermentation, and the microorganisms involved are common in food production. International bodies like JECFA have evaluated similar fermented products. At typical consumption levels, it is not associated with adverse health effects. Evidence does not suggest significant health risks from its use in food.
