What it is
Dry sourdough or rye is a leavening agent made from a starter culture of wild yeasts and bacteria, typically found in rye flour. This starter is dried for preservation and ease of use. When rehydrated and added to dough, it helps it rise and imparts a characteristic tangy flavor.
Why it's used
Manufacturers use dry sourdough or rye primarily as a leavening agent and flavor enhancer in baked goods. It is commonly found in breads, crackers, and other savory snacks, contributing to their texture and taste.
Health notes
Dry sourdough or rye is generally recognized as safe (GRAS) by the FDA for use in food. It is a natural product of fermentation and does not have specific regulatory limits set by international bodies like JECFA or EFSA. While some people may experience digestive discomfort from gluten-containing grains like rye, this is not typically associated with the fermentation process itself at normal consumption levels.
Allergen info
Dry sourdough or rye is derived from rye, which is a grain. While not one of the nine major allergens, it contains gluten, which is a concern for individuals with celiac disease or gluten sensitivity.
