Introduction to Fresh Yeast

Fresh yeast is a food product used for leavening baked goods such as bread, pizza, and pastries. It is primarily composed of living organisms called yeasts, particularly Saccharomyces cerevisiae..

The production of fresh yeast takes place in specialized laboratories. Typically, fresh yeast is cultivated on a nutrient substrate such as malt or cane sugar molasses. During the cultivation process, yeasts multiply and ferment the sugars present in the substrate, producing carbon dioxide and alcohol.

Once fermentation is complete, the yeast is harvested and undergoes processing. It is usually partially dehydrated and compressed into blocks or cubes, which are then packaged and distributed for sale as fresh yeast.

Fresh yeast is characterized by a soft and moist texture. It has a beige or light brown color and a slightly fermented characteristic aroma. Before use, it needs to be activated by mixing it with warm water and sugar so that the yeasts awaken and begin fermenting again.

The use of fresh yeast imparts distinct aroma and texture to baked goods, thanks to the production of carbon dioxide during fermentation. It is a versatile ingredient widely used in baking and the preparation of leavened desserts.

Fresh yeast is an essential ingredient in many bread, pizza, and pastry recipes. It is a natural product rich in leavening properties, giving dough a unique flavor and a soft texture.

How to Use Fresh Yeast in Recipes
