How is yeast extract produced?

Yeast extract is made by breaking down the cell walls in yeast. To help you visualize, here is the production process in three steps.

Step 1 Fermentation

To fit with the customer’s final expectation and depending on the uses, a specific yeast strain is selected. Once this selection is made, yeast fermentation starts. It is conducted in tanks under regular growing conditions. The yeast grows to reach a sufficient amount to undergo.

Step 2 Breakage

The yeast is heated, and the enzymes of the yeast break down the cell walls into smaller components. Yeast content is solvable by thermal heat treatment and selection of tasty components.

Step 3 Separation

The cell walls are separated from the extract sea yeast extracts results of the simple action of enzymes and heat on yeast extract and natural origin an animal-free ingredient.

Different forms of yeast extract

The result of this process is a yeast extract powder, liquid, or paste:
• Paste and liquid forms are obtained after the standard production that ends after evaporation and
concentration.
• Powder form needs an additional step which consists of spray drying. The liquid is fed into a
so-called spray tower and dried using hot air. Then water evaporates, yeast extract falls, and is collected at the base of the tower; it confers its final texture.


Depending on intended usage, a form is preferred due to its technological properties and capacity of incorporation into a formula and industrial production lines.

What are the characteristics of yeast extract?

Yeast extract comes from fresh yeast and is, therefore, a natural origin ingredient.

No synthetic or chemical ingredients are added during its production. It has the following characteristics:

  • Process resistant ingredients (acid, heat, and freeze), from oven, cooking to the canning process.
  • Animal-free ingredients, suitable for vegan and vegetarian products
