Yeast raised products have been a staple in many cuisines around the world for centuries. From the fluffy texture of bread to the crispy crust of pizza, yeast plays a crucial role in creating some of our favorite foods. But what exactly are yeast raised products, and how do they differ from other types of baked goods? In this article, we will delve into the world of yeast raised products, exploring their history, production process, and the various types of products that utilize yeast as a leavening agent.
Introduction to Yeast Raised Products
Yeast raised products are baked goods that use yeast as a leavening agent to produce carbon dioxide gas, causing the dough to rise. This process, known as fermentation, is what gives yeast raised products their characteristic texture and flavor. Yeast is a microorganism that feeds on sugars and produces carbon dioxide as a byproduct, which gets trapped in the dough, causing it to expand. The fermentation process can take anywhere from a few hours to several days, depending on the type of yeast and the conditions in which it is allowed to ferment.
History of Yeast Raised Products
The use of yeast in baking dates back to ancient times, with evidence of yeast-based bread production found in ancient Egyptian and Greek civilizations.
