Yeast Meaning

What is yeast:

Yeast is a single-celled fungus that feeds on sugars and hydrogenated compounds through the enzymes it produces. These enzymes ferment the sugars, transforming them into carbon dioxide and alcohol.

Yeast, as part of the fungi kingdom, belongs to the group of single-celled ascomycete decomposers.

Also called a ferment, it is used in cooking, since its enzymes help to increase the size of the dough and ferment cereals and grapes for the creation of alcoholic beverages such as beer.

Types of yeast

There are several types of yeasts, such as chemical ones, they act as enzymes and only during cooking so they are only used to bake cookies and not to make bread. Some daily use chemical yeasts are: baking soda, baking powder, and chemical emulsifiers.

Nutritional yeasts, called pressed, natural or fresh yeasts act at less than 50 degrees generating carbon dioxide that helps the growth of the bread dough.

You can find a wide variety of types of yeast for the fermentation of wine and beer depending on the flavor you want to obtain. Ale beer, for example, uses the type saccharomyces cerevisiae.
