In the world of health foods and dietary supplements, nutritional yeast has emerged as a versatile and nutrient-dense ingredient that’s capturing the attention of vegans, vegetarians, and health enthusiasts alike. But what exactly is nutritional yeast, and why has it become such a staple in modern diets?

This golden-yellow powder or flake not only enhances the taste of your dishes but also packs a powerful nutritional punch. Let’s learn more about this ingredient, from its production to the different ways you can include this superfood in your everyday meals.

Yeast is a type of fungus that plays a vital role in various biological and culinary processes. It exists as single-celled microorganisms and comes in many different species, each with unique characteristics and uses. The most commonly known yeast is Saccharomyces cerevisiae, which is widely used in baking, brewing, and winemaking due to its fermentation capabilities.

Here is a breakdown on the types of yeast and what role each plays when deployed in the food industry: 

Types of Yeast  Role
Baker’s Yeast  Used in baking to leaven bread and other baked goods.
Brewer’s Yeast  Employed in the production of beer and alcoholic beverages. 
Nutritional Yeast  Used as a dietary supplement and a flavor enhancer, known for its nutty, cheesy taste.


In addition to the above, we also have wine yeast and wild yeast. Yeast is a fascinating and versatile organism that significantly impacts our food and drink production, nutrition, and scientific research. Its ability to transform ingredients through fermentation and its rich nutrient profile make it an indispensable part of our daily lives.

What is Nutritional Yeast?

Nutritional yeast, often informally referred to as “nooch,” is a deactivated yeast derived from Saccharomyces cerevisiae. Unlike the active yeast used in baking and brewing, this yeast doesn’t froth or ferment. Instead, it offers a unique combination of nutrients, including a robust profile of B vitamins, protein, and essential minerals, all wrapped up in a savory, cheese-like flavor that makes it a culinary favorite.

From sprinkling over popcorn to stirring into sauces, the uses of this yeast are as diverse as its benefits. Rich in antioxidants, protein, and fiber, it supports immune function, promotes healthy digestion, and provides essential nutrients that are often hard to come by, especially in plant-based diets.

How is Nutritional Yeast Produced?

The production of nutritional yeast involves several steps:

1. Cultivation

The yeast is grown on a nutrient-rich medium, typically consisting of glucose, derived from either sugarcane or beet molasses.

2. Fermentation

During this stage, the yeast cells ferment the sugars, multiplying and producing a variety of nutrients, including B vitamins, proteins, and minerals.

3. Harvesting

Once the fermentation process is complete, the yeast is harvested, usually through a process of centrifugation. What centrifugation does is it spins the mixture at high speed so that the yeast cells separate from the liquid. 

4. Deactivation

The yeast is then pasteurized, which deactivates it. This means the yeast will not ferment further, making it suitable for consumption as a food product.

5. Drying

The deactivated yeast is dried at low temperatures to preserve its nutritional content. It is then flaked or powdered for packaging.
