what is meant by fermentation
Answers
Answer:
Fermentation is a process used to produce wine, beer, yogurt and other products. Here's a look at the chemical process that occurs during fermentation.
Fermentation Definition
Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or a sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol. Bacteria perform fermentation, converting carbohydrates into lactic acid. The study of fermentation is called zymology.
Fermentation is a natural process. People applied fermentation to make products such as wine, mead, cheese, and beer long before the biochemical process was understood. In the 1850s and 1860s, Louis Pasteur became the first zymurgist or scientist to study fermentation when he demonstrated fermentation was caused by living cells. However, Pasteur was unsuccessful in his attempts to extract the enzyme responsible for fermentation from yeast cells. In 1897, German chemist Eduard Buechner ground yeast, extracted fluid from them, and found the liquid could ferment a sugar solution. Buechner's experiment is considered the beginning of the science of biochemistry, earning him the 1907 Nobel Prize in chemistry.
Examples of Products Formed by Fermentation
Most people are aware of food and beverages that are fermentation products, but may not realize many important industrial products results from fermentation.
Beer
Wine
Yogurt
Cheese
Certain sour foods containing lactic acid, including sauerkraut, kimchi, and pepperoni
Bread leavening by yeast
Sewage treatment
Some industrial alcohol production, such as for biofuels
Hydrogen gas.
