Ethanol fermentation, also called alcoholic fermentation, is a biological process which converts sugars such as glucose, fructose, and sucrose into cellular energy, producing ethanol and carbon dioxide as by-products. Because yeasts perform this conversion in the absence of oxygen, alcoholic fermentation is considered an anaerobic process.
Commercially produced banana wine is a clear, slightly sparkling alcoholic beverage with a longer shelf-life than banana beer, which is spoiled easily and therefore not stored for long periods. [ 3 ] [ 4 ] Depending on the strain of yeast and amount of sugar added, the sweetness and alcohol level in the final product is variable.
Banana beer is made from ripe (but not over-ripe) East African Highland bananas (Musa acuminata Colla (AAA-EA), Mbidde clone set). [5] To accelerate the ripening of bananas, a hole is dug in the ground, lined with dried banana leaves which are then set on fire. Fresh banana leaves are laid on top of them, then the unripe bananas.
In Germany fruit dessert wines are fruit wines with more than 12.0% vol. In Austria they need an alcohol content of at least 13.0% vol. to a maximum of 22.0% vol. The total alcohol content may be increased by adding alcohol, fruit spirits, sugar, fruit juice and fruit juice concentrate to the fruit wine or cider.
In alcohol fermentation, when a glucose molecule is oxidized, ethanol (ethyl alcohol) and carbon dioxide are byproducts. The organic molecule that is responsible for renewing the NAD+ supply in this type of fermentation is the pyruvate from glycolysis.
Tonto is a traditional drink indigenous to Ugandan and a fermented beverage made from bananas. It is also referred to as mwenge bigere. Tonto is just one of the drinks made from Bananas others include Waragi and wines all made from different types of bananas. Tonto is made by ripening green
In ethanol fermentation, one glucose molecule is converted into two ethanol molecules and two carbon dioxide (CO 2) molecules. [11] [12] It is used to make bread dough rise: the carbon dioxide forms bubbles, expanding the dough into a foam. [13] [14] The ethanol is the intoxicating agent in alcoholic beverages such as wine, beer and liquor. [15]
In biochemistry, fermentation theory refers to the historical study of models of natural fermentation processes, especially alcoholic and lactic acid fermentation. Notable contributors to the theory include Justus Von Liebig and Louis Pasteur , the latter of whom developed a purely microbial basis for the fermentation process based on his ...
