How much protein is in sourdough bread?

Sourdough bread typically contains less protein than other types of bread. On average, it contains about 8-11% protein, while conventional yeast bread contains about 12-15%. The percentage of protein in sourdough bread depends on the specific recipe and ingredients used. For example, adding ingredients like wheat germ or soy flour can increase the protein content. Additionally, the length of the fermentation process can also affect the protein content, as longer fermentation times can lead to increased protein breakdown.
