FOOD PROPERTIES OF BREWER’S YEAST
What is brewer’s yeast?
It is a type of leavening or unicellular fungus (Saccharomyces cerevisiae) that is used for the production of beer. The scientific name of the genus of the fungus comes from the Greek “sakar” meaning sugar and “mikes” which means sugar. The cerevisae species name comes from Latin and means beer.
The name of this fungus is due to the fact that it feeds on sugars. More specifically, when being in a sugary place, under appropriate conditions of temperature and humidity, a transformation is produced of sugars (glucose) plus the water of the environment in which it dwells in carbon dioxide and alcohol (ethanol), as described in the following formula:
When was brewer’s yeast discovered?
Probably the discovery of this process was made by chance in Mesopotamia between 10,000 and 6000 BC, when a farmer who wanted to make barley bread, missed the proportion of ingredients including flour mixture and water much more water than flour. The fermentation process originated an alcoholic liquid with a distinctive taste that we now know under the name of beer. The organism that made this transformation possible is now known as brewer’s yeast.
Whether this process was or not the origin of beer, the fact is that we know that in Mesopotamia people dominated the fermentation technique for barley. In Egypt, papyri tell us how undercooked bread was left to ferment in water waiting for the transformation to occur.
