fungus
A pair of panther cap mushrooms (Amanita pantherina). Closely related to the death cap mushroom (Amanita phalloides), the panther cap is highly poisonous.
Fungi, specifically selected strains of the yeast Saccharomyces cerevisiae, are essential to the production of bread, beer, and wine because of their ability to perform fermentation.1
During this process, the yeast feeds on sugars present in the ingredients, converting them into ethanol (alcohol) and carbon dioxide. The utility of these byproducts depends on the desired end product:1
- Baking: The primary goal is leavening. The carbon dioxide produced by the yeast becomes trapped in the dough, causing it to rise and creating the desired texture. The alcohol produced during this process is typically driven off during the baking stage.12
- Brewing and Winemaking: The primary goal is the production of ethanol. In these beverages, the alcohol is the desired product, and in some cases, a portion of the carbon dioxide is retained to provide carbonation.1
Beyond these roles, yeast is a highly nutritious organism, composed of approximately 50 percent protein and serving as a rich source of various vitamins.1
