What is Nutritional Yeast?

Nutritional yeast, often referred to as “nooch,” is a deactivated yeast, typically Saccharomyces cerevisiae, which is the same species used in baking and brewing. However, unlike brewer’s yeast, nutritional yeast undergoes a heating and drying process that renders it inactive.

Tracing its origins back to the 20th century, nutritional yeast was initially developed as a supplement for its high nutritional value. Over time, it evolved into a culinary staple cherished for its unique taste and health benefits.

Nutritional yeast, scientifically known as Saccharomyces cerevisiae, is a deactivated yeast strain. It’s typically grown on molasses and then harvested, washed, and dried to create yellow flakes or powder. This powerhouse ingredient is celebrated for its savory, cheese-like flavor, making it a popular choice among vegans and vegetarians as a dairy-free alternative.
