The Many Aliases of Nutritional Yeast
Nutritional yeast, a popular food additive, is known by several names, reflecting its widespread use in vegan and vegetarian cooking. The search for its alternative names often leads to a few key terms. The most common and widely recognized alias is undoubtedly 'nooch,' a colloquial and affectionate term that has been adopted by the plant-based community.
Where Do the Other Names Come From?
Beyond 'nooch,' other names like 'savory yeast flakes' have been used, particularly in the UK and Australia, where some brands use this description on their packaging. This name directly references its savory, cheese-like flavor and its flaky form, which distinguishes it from other types of yeast. In addition, some people in the past referred to it by brand names like 'Brufax,' further adding to its list of aliases.
Nutritional Yeast vs. Other Yeast Types
One of the most important distinctions to understand when exploring the names for nutritional yeast is how it differs from other yeasts derived from the same Saccharomyces cerevisiae species. It's not a direct substitute for other yeasts used in baking or brewing, and misunderstanding this can lead to confusion. Here is a comparison to clarify the differences:
| Feature | Nutritional Yeast ('Nooch') | Brewer's Yeast | Baker's Yeast |
|---|---|---|---|
| State | Inactive (deactivated) | Inactive byproduct or active | Active |
| Purpose | Food seasoning and supplement | Supplement or beer fermentation | Leavening agent for bread |
| Taste | Cheesy, nutty, savory, umami | Very bitter | Earthy, but bland after baking |
| Source | Grown on molasses, harvested and dried | Byproduct of brewing beer | Cultivated for baking |
| B12 Content | Often fortified with B12 | Does not contain B12 naturally | Minimal, if any |
As the table shows, while they share a common lineage, their processing, purpose, and flavor profile are vastly different. It is the deactivation process that gives nutritional yeast its cheesy flavor, as the heat treatment releases savory glutamic acid, and ensures it doesn't ferment.
Culinary Uses of Nutritional Yeast
Whether you call it 'nooch' or savory flakes, this ingredient is incredibly versatile in the kitchen. Its cheesy, savory, and nutty flavor makes it an excellent addition to a wide variety of dishes, especially for those avoiding dairy.
Common ways to use nutritional yeast:
- Vegan Cheese Sauce: It is the star ingredient for creating dairy-free alternatives to cheese sauces for dishes like macaroni and 'cheese'.
- Popcorn Topping: A light, savory dust sprinkled over popcorn for a cheesy flavor without the butter.
- Pasta Alternative: Used in place of grated parmesan cheese on pasta dishes.
- Roasted Vegetables: Adds a savory, nutty crust to vegetables like broccoli or kale when roasted.
- Soups and Gravies: Blends easily into soups and gravies to provide a creamy texture and rich, savory flavor.
- Tofu Scramble: Used to enhance the flavor of a vegan scramble, mimicking the taste of eggs with cheese.
- Pesto: Substitute parmesan with nutritional yeast for a delicious, savory vegan pesto.
Nutritional Benefits and Considerations
Beyond its flavor, nutritional yeast earns its name from its high nutritional value. It is a complete protein, containing all nine essential amino acids. Most commercially available 'nooch' is also fortified with B-complex vitamins, including the crucial Vitamin B12, which is essential for vegan diets. Always check the label, as unfortified versions do not contain B12 naturally.
It is also a good source of fiber, and some brands provide minerals like zinc and selenium. Studies suggest the beta-glucans in nutritional yeast may help lower cholesterol and support immune function.
For most people, consuming nutritional yeast in moderation is safe. However, individuals with yeast allergies or those with conditions that make them sensitive to glutamate should exercise caution. Those taking certain medications, like MAOIs, should consult a doctor, as yeast contains tyramine.
Conclusion: More Than Just 'Nooch'
So, does nutritional yeast have another name? Absolutely. While 'nooch' is a common and easy-to-remember nickname, other terms like 'savory yeast flakes' also refer to this popular ingredient. Understanding the different names is key to avoiding confusion, especially when distinguishing it from its brewing and baking cousins. With its cheesy, savory flavor and robust nutritional profile, nutritional yeast is a versatile and valuable addition to any pantry, regardless of what you call it.
