What is Yeast?

Yeast is a type of single-celled fungus used in various food and beverage production processes, including baking and brewing. It is typically made by cultivating strains of Saccharomyces cerevisiae in a nutrient-rich solution.

In food production, yeast is primarily used as a leavening agent in baking. It ferments sugars, producing carbon dioxide and ethanol, which cause dough to rise and develop a light texture. Yeast is also essential in alcoholic beverage production, contributing to fermentation.

While yeast is generally considered safe and nutritious, providing protein, B vitamins, and minerals, some individuals may have sensitivities or allergies that cause adverse reactions.

Commonly found in: bread, beer, wine, pastries, crackers
