These processes also were included in early fermentation of beer.[11] These processes were introduced in early Mesopotamia, Egypt, and India, and still use the same basic biological methods. In brewing, malted grains (containing enzymes) convert starch from grains into sugar and then adding specific yeasts to produce beer. In this process, carbohydrates in the grains were broken down into alcohols such as ethanol. Later other cultures produced the process of lactic acid fermentation which allowed the fermentation and preservation of other forms of food, such as soy sauce. Fermentation was also used in this time period to produce leavened bread | The Project Gutenberg EBook of Fathers of Biology by Charles McRae This eBook is for the use of anyone anywhere at no cost and with almost no restrictions whatsoever.
