Brewers Yeast Protein

Brewers yeast protein is derived from the inactive cells of *Saccharomyces cerevisiae*, a type of yeast used in brewing beer and baking bread. The yeast is grown in a nutrient-rich medium, then harvested and processed to extract its protein content. This process typically involves methods like cell disruption and separation to isolate the protein.

Manufacturers add brewers yeast protein as a source of plant-based protein and certain B vitamins. It can also contribute a savory, umami flavor to foods. It is commonly found in snacks like chips and pretzels, as well as in some baked goods and nutritional supplements.

Brewers yeast protein is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. It is a source of protein and B vitamins, which are essential nutrients. International bodies like the WHO/FAO's JECFA have evaluated yeast and its components, but no specific ADI is set for brewers yeast protein. Evidence on its health effects at typical consumption levels is generally positive, supporting its role as a nutrient source.
