What is Yeast

Yeast is a single celled microorganism that belongs to fungus kingdom. It’s everywhere – on plants and animals, in soil, in the air. It is used as catalyst for fermentation, the process of breaking down carbohydrates into alcohols and carbon dioxide.  Carbon dioxide is essential in bread making because it makes the bread rise. It is a gas produced when yeast feeds on sugars in flour as a by-product of its metabolism.
