The Following: Active Dry Yeast

Active dry yeast is a common form of Saccharomyces cerevisiae, a single-celled microorganism. It's a dried, dormant form of yeast that becomes active when exposed to warm liquid. Yeast is cultivated in a controlled environment, typically on a molasses-based medium, and then dried to create the active dry form.

Active dry yeast is primarily used as a leavening agent in baked goods like bread, rolls, and pizza dough. When activated, it consumes sugars and produces carbon dioxide gas, which causes dough to rise and become light and airy. It is also used in some fermented beverages and foods.

Active dry yeast is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is a source of B vitamins and protein. JECFA has evaluated yeast and established acceptable daily intakes. While generally considered safe, some individuals may experience digestive upset from consuming large amounts of yeast.
