Tibicos water crystals made with Muscovado. This is a list of fermented foods, which are foods produced or preserved by the action of microorganisms.In this context, fermentation typically refers to the fermentation of sugar to alcohol using yeast, but other fermentation processes involve the use of bacteria such as lactobacillus, including the making of foods such as yogurt and sauerkraut.
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.
Grapes being trodden to extract the juice and made into wine in storage jars. Tomb of Nakht, 18th dynasty, Thebes, Ancient Egypt. Sourdough starter. In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—without an oxidizing agent being used in the reaction.
In ethanol fermentation, one glucose molecule is converted into two ethanol molecules and two carbon dioxide (CO 2) molecules. [10] [11] It is used to make bread dough rise: the carbon dioxide forms bubbles, expanding the dough into a foam. [12] [13] The ethanol is the intoxicating agent in alcoholic beverages such as wine, beer and liquor. [14]

Burton Union fermentation system, Coors Visitor Centre. The enzymes used in the reaction are provided by the mold Rhizopus nigricans. [11] Just as it is commonly known, alcohol of all types and brands are also produced by way of fermentation and distillation. Moonshine is a classic example of how this is carried out. Finally, foods such as ...
A selection of alcoholic drinks (from left to right): red wine, malt whisky, lager, sparkling wine, lager, cherry liqueur and red wine Alcoholic beverages and production relationships. Drinks containing alcohol are typically divided into three classes—beers, wines, and spirits—with alcohol contents between 3% and 50%.
If fermentation is allowed to run to completion, the resulting wine is (in most cases) low in sugar and is considered a dry wine. Adding alcohol earlier in the fermentation process results in a sweeter wine. For drier fortified wine styles, such as sherry, the alcohol is added shortly before or after the end of the fermentation.
