Yeast Extract 

Definition & Names

• Known as Yeast Extract, Baker’s Yeast Extract, Yeast Essence.

• Derived from baker’s yeast (Saccharomyces cerevisiae).

• CAS number: 8013-01-2.

Production Process

• Made through autolysis: yeast cells are heated, their own enzymes break down proteins into simpler compounds.

• Cell walls are removed, leaving a nutrient-rich liquid that can be dried into paste or powder.

Composition & Properties

• Contains proteins, amino acids, carbohydrates, vitamins (B-complex except B12), and minerals.

• Rich in glutamic acid, which provides the umami taste.

• Protein quality is comparable to egg or milk according to FAO.

Applications

• Widely used in soups, sauces, bouillons, meat products, ready meals, and savory snacks.

• Also used in microbiological media as a nutrient source.

• Vegan- and vegetarian-friendly, since it contains no meat.

Benefits

• Supplies all essential amino acids with high bioavailability.

• Provides B vitamins, fiber, and minerals.

• Non-allergenic compared to soy proteins.

• Enhances flavor, allowing reduced salt usage in recipes.

• Typically used in very small amounts (<1%).

Flavor Profile

• Similar to homemade meat bouillon.

• Delivers umami taste naturally via glutamate.

• Different from MSG:

  • Yeast extract contains ~5% glutamate (natural, complex flavor).

  • MSG is pure glutamate (100%) and only boosts existing taste without adding its own.

In short: Yeast extract is a natural, nutrient-rich flavor enhancer made from yeast cells. It provides umami taste, improves food flavor, reduces salt needs, and is suitable for vegan diets. Unlike MSG, it is a complex ingredient with nutritional value, not just a single additive.
