Baker's Yeast is a type of fungus used in baking to help dough rise. It works by fermenting sugars in the dough, producing carbon dioxide gas and alcohol. This process creates air bubbles, making the bread light and fluffy. Baker's yeast is commonly found in two forms: active dry yeast and instant yeast, both of which are easy to use in various recipes. In addition to baking, Baker's Yeast is also used in brewing beer and making wine. It plays a crucial role in these processes by converting sugars into alcohol and carbon dioxide, contributing to the flavor and texture of the final product.
