Symbiotic Fermentation
Symbiotic fermentation is a form of fermentation in which multiple organisms (yeasts, acetic acid bacteria, lactic acid bacteria and others) interact in symbiosis in order to produce the desired product. For example, a yeast may produce ethanol, which is then consumed by an acetic acid bacterium. Described early on as the fermentation of sugars following saccharification in a mixed fermentation process. History The earliest mention of the term can be found in a lecture given by Dr. Allan Macfadyen of the Jenner Institute of Preventative Medicine in 1902. Dr. Macfadyen described symbiotic fermentation as noting "a close relationship between the organisms at work, the action of one aiding or modifying the action of the other, whilst both members are more active as a results of the partnership." Fermentative microorganisms have had a deep history as seen by kefir and kumis fermentations of milk by Nomadic tribes in Russia, as well as Japanese koji fermentation (see ''Aspergillus oryz ...

Fermentation
Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. In food production, it may more broadly refer to any process in which the activity of microorganisms brings about a desirable change to a foodstuff or beverage. The science of fermentation is known as zymology. In microorganisms, fermentation is the primary means of producing adenosine triphosphate (ATP) by the degradation of organic nutrients anaerobically. Humans have used fermentation to produce foodstuffs and beverages since the Neolithic age. For example, fermentation is used for preservation in a process that produces lactic acid found in such sour foods as pickled cucumbers, kombucha, kimchi, and yogurt, as well as for producing alcoholic beverages such as wine and beer. Fermentation also occurs within the gastrointestinal tracts of all a ...

Wine
Wine is an alcoholic drink typically made from fermented grapes. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide, releasing heat in the process. Different varieties of grapes and strains of yeasts are major factors in different styles of wine. These differences result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the grape's growing environment (terroir), and the wine production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production. Wines not made from grapes involve fermentation of other crops including rice wine and other fruit wines such as plum, cherry, pomegranate, currant and elderberry. Wine has been produced for thousands of years. The earliest evidence of wine is from the Caucasus ...

Whisky
Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, which are typically made of charred white oak. Uncharred white oak casks previously used for the aging of sherry are also sometimes used. Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels. Etymology The word ''whisky'' (or ''whiskey'') is an anglicisation of the Classical Gaelic word (or ) meaning "water" (now written as in Modern Irish, and in Scottish Gaelic). This Gaelic word shares its ultimate origins with Germanic ''water'' and Slavic ''voda'' of the same meaning. Distilled alcohol was known in Latin as ("water of life"). This was translated into Old I ...

Soy Sauce
Soy sauce (also called simply soy in American English and soya sauce in British English) is a liquid condiment of Chinese origin, traditionally made from a fermented paste of soybeans, roasted grain, brine, and '' Aspergillus oryzae'' or ''Aspergillus sojae'' molds. It is considered to contain a strong umami taste. Soy sauce in its current form was created about 2,200 years ago during the Western Han dynasty of ancient China, and it has spread throughout East and Southeast Asia where it is used in cooking and as a condiment. Use and storage Soy sauce can be added directly to food, and is used as a dip or salt flavor in cooking. It is often eaten with rice, noodles, and sushi or sashimi, or can also be mixed with ground wasabi for dipping. Bottles of soy sauce for salty seasoning of various foods are common on restaurant tables in many countries. Soy sauce can be stored at room temperature. History East Asia China Soy sauce (, ) is considered almost as old as soy p ...

Vinegar
Vinegar is an aqueous solution of acetic acid and trace compounds that may include flavorings. Vinegar typically contains 5–8% acetic acid by volume. Usually, the acetic acid is produced by a double fermentation, converting simple sugars to ethanol using yeast, and ethanol to acetic acid by acetic acid bacteria. Many types of vinegar are available, depending on source materials. It is now mainly used in the culinary arts as a flavorful, acidic cooking ingredient, or in pickling. Various types are used as condiments or garnishes, including balsamic vinegar and malt vinegar. As the most easily manufactured mild acid, it has a wide variety of industrial and domestic uses, including use as a household cleaner. Etymology The word "vinegar" arrived in Middle English from Old French (''vyn egre''; sour wine), which in turn derives from Latin: ''vinum'' (wine) + ''acer'' (sour). Chemistry The conversion of ethanol (CH3CH2OH) and oxygen (O2) to acetic acid (CH3COOH) takes plac ...

Shōchū
is a Japanese distilled beverage. It is typically distilled from rice, barley, sweet potatoes, buckwheat, or brown sugar, though it is sometimes produced from other ingredients such as chestnut, sesame seeds, potatoes, or even carrots. Typically shōchū contains 25% alcohol by volume, which is weaker than baijiu, whiskey or vodka but stronger than huangjiu, sake or wine. It is not uncommon for multiply distilled shōchū, which is more likely to be used in mixed drinks, to contain up to 35% alcohol by volume. Etymology The word is the Japanese rendition of the Chinese ''shaojiu'' (), meaning "burned liquor", which refers to the heating process during distillation. The Chinese way of writing ''shaojiu'' with the character 酒 is considered archaic and obsolete in modern Japanese, which uses the character 酎. Nevertheless, both characters mean "liquor". Culture Drinking ''Shōchū'' should not be confused with sake, a brewed rice wine. Its taste is usually far less fr ...

Lambic
Lambic () is a type of beer brewed in the Pajottenland region of Belgium southwest of Brussels and in Brussels itself since the 13th century. Types of lambic beers include gueuze, kriek lambic and framboise. Lambic differs from most other beers in that it is fermented through exposure to wild yeasts and bacteria native to the Zenne valley, as opposed to exposure to carefully cultivated strains of brewer's yeast. This process gives the beer its distinctive flavour: dry, vinous, and cidery, often with a tart aftertaste. Etymology This beverage is first mentioned in 1794 as ''allambique''. The initial 'a' was dropped early on, so that in an 1811 advert it was called ''lambicq'', though it was sometimes referred to as ''alambic'' as late as 1829. The name may stem from alembic, a type of still used for producing local spirits like cognac and jenever (but not used in the production of lambic). Breweries in and around Lembeek, a village near Halle, Belgium, have attempted to a ...

Sake
Sake, also spelled saké ( ; also referred to as Japanese rice wine), is an alcoholic beverage of Japanese origin made by fermenting rice that has been polished to remove the bran. Despite the name ''Japanese rice wine'', sake, and indeed any East Asian rice wine (such as huangjiu and cheongju), is produced by a brewing process more akin to that of beer, where starch is converted into sugars which ferment into alcohol, whereas in wine, alcohol is produced by fermenting sugar that is naturally present in fruit, typically grapes. The brewing process for sake differs from the process for beer, where the conversion from starch to sugar and then from sugar to alcohol occurs in two distinct steps. Like other rice wines, when sake is brewed, these conversions occur simultaneously. The alcohol content differs between sake, wine, and beer; while most beer contains 3–9% ABV, wine generally contains 9–16% ABV, and undiluted sake contains 18–20% ABV (although this is often ...

Kefir
Kefir ( ; also spelled as kephir or kefier; ; ; ) is a fermented milk drink similar to a thin yogurt or ayran that is made from kefir grains, a specific type of mesophilic symbiotic culture. The drink originated in the North Caucasus, in particular the Elbrus region along the upper mountainous sections of Circassia, Karachay and Balkaria, from where it came to Russia, and from there it spread to Europe and the United States, where it is prepared by inoculating the milk of cows, goats, or sheep with kefir grains. Kefir is a breakfast, lunch, and dinner drink popular across Russia, Belarus, Estonia, Hungary, Latvia, Lithuania, Poland, Romania, and Ukraine - where it is known as an affordable health drink. It is also known in Norway, Sweden, and Finland, where buttermilk-type fermented dairy drinks are common. Kefir is common particularly among Russian and Estonian minorities. In South Slavic countries, kefir is consumed at any time of the day, especially with zelnik/zelja ...

Invertase
Invertase is an enzyme that catalyzes the hydrolysis (breakdown) of sucrose (table sugar) into fructose and glucose. Alternative names for invertase include , saccharase, glucosucrase, beta-h-fructosidase, beta-fructosidase, invertin, sucrase, maxinvert L 1000, fructosylinvertase, alkaline invertase, acid invertase, and the systematic name: beta-fructofuranosidase. The resulting mixture of fructose and glucose is called inverted sugar syrup. Related to invertases are sucrases. Invertases and sucrases hydrolyze sucrose to give the same mixture of glucose and fructose. Invertase is a glycoprotein that hydrolyses (cleaves) the non-reducing terminal beta-fructofuranoside residues. Thus, its systematic name is beta-fructofuranosidase. Invertases cleave the O-C(fructose) bond, whereas the sucrases cleave the O-C(glucose) bond. Invertase cleaves the alpha-1,2-glycosidic bond of sucrose. For industrial use, invertase is usually derived from yeast. It is also synthesized by bees, which us ...
