Fermentation in food processing
–
Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic conditions. Fermentation usually implies that the action of microorganisms is desired, the science of fermentation is known as zymology or zymurgy. The term fermentation sometimes refers specifically to the conversion of sugars into ethanol, producing alcoholic drinks such as wine, beer. However, similar processes take place in the leavening of bread, other widely consumed fermented foods include vinegar, olives, and cheese. More localised foods prepared by fermentation may also be based on beans, grain, vegetables, fruit, honey, dairy products, fish, meat, since ancient times, humans have exploited the fermentation process. Seven-thousand-year-old jars containing the remains of wine, now on display at the University of Pennsylvania, were excavated in the Zagros Mountains in Iran. There is strong evidence that people were fermenting alcoholic drinks in Babylon c.3000 BC, ancient Egypt c.3150 BC, pre-Hispanic Mexico c.2000 BC, the French chemist Louis Pasteur founded zymology, when in 1856 he connected yeast to fermentation. When studying the fermentation of sugar to alcohol by yeast, Pasteur concluded that the fermentation was catalyzed by a force, called ferments. The ferments were thought to only within living organisms. Alcoholic fermentation is an act correlated with the life and organization of the yeast cells, not with the death or putrefaction of the cells, nevertheless, it was known that yeast extracts can ferment sugar even in the absence of living yeast cells. In 1907 he received the Nobel Prize in Chemistry for his research, one year earlier, in 1906, ethanol fermentation studies led to the early discovery of NAD+. Food fermentation is the conversion of sugars and other carbohydrates into alcohol or preservative organic acids, all three products have found human uses. The production of carbon dioxide is used to leaven bread, the production of organic acids is exploited to preserve and flavor vegetables and dairy products. It has more cases of botulism than any state in the United States of America. The World Health Organization has classified pickled foods as possibly carcinogenic, other research found that fermented food contains a carcinogenic by-product, ethyl carbamate. A2009 review of the studies conducted across Asia concluded that regularly eating pickled vegetables roughly doubles a persons risk for esophageal squamous cell carcinoma.

Distillation
–
Distillation is a process of separating the component or substances from a liquid mixture by selective evaporation and condensation. Distillation may result in complete separation, or it may be a partial separation that increases the concentration of selected components of the mixture. In either case the process exploits differences in the volatility of the mixtures components, in industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process and not a chemical reaction. For example, In the fossil fuel industry distillation is a class of operation in obtaining materials from crude oil for fuels. Distillation permits separation of air into its components — notably oxygen, nitrogen, Distillation of fermented products produces distilled beverages with a high alcohol content, or separates out other fermentation products of commercial value. An installation for distillation, especially of alcohol, is a distillery, the distillation equipment is a still. Distillation is an old method of artificial desalination. Aristotle wrote about the process in his Meteorologica and even that ordinary wine possesses a kind of exhalation, later evidence of distillation comes from Greek alchemists working in Alexandria in the 1st century AD. Distilled water has been known since at least c,200, when Alexander of Aphrodisias described the process. Work on distilling other liquids continued in early Byzantine Egypt under the Greek-Egyptian Zosimus of Panopolis, Distillation in China could have begun during the Eastern Han Dynasty, but archaeological evidence indicates that actual distillation of beverages began in the Jin and Southern Song dynasties. A still was found in a site in Qinglong, Hebei province dating to the 12th century. Distilled beverages were more common during the Yuan dynasty, arabs learned the process from the Alexandrians and used it extensively in their chemical experiments. Clear evidence of the distillation of alcohol comes from the School of Salerno in the 12th century, fractional distillation was developed by Tadeo Alderotti in the 13th century. In 1500, German alchemist Hieronymus Braunschweig published Liber de arte destillandi the first book dedicated to the subject of distillation. In 1651, John French published The Art of Distillation the first major English compendium of practice and this includes diagrams with people in them showing the industrial rather than bench scale of the operation. As alchemy evolved into the science of chemistry, vessels called retorts became used for distillations, riveted joints were often kept tight by using various mixtures, for instance a dough made of rye flour. These alembics often featured a system around the beak, using cold water for instance. Today, the retorts and pot stills have largely supplanted by more efficient distillation methods in most industrial processes

Orange (fruit)
–
The orange is the fruit of the citrus species Citrus × sinensis in the family Rutaceae. It is also called orange, to distinguish it from the related Citrus × aurantium. The sweet orange reproduces asexually, varieties of sweet orange arise through mutations, the orange is a hybrid between pomelo and mandarin. It has genes that are ~25% pomelo and ~75% mandarin, however, it is not a simple backcrossed BC1 hybrid, the chloroplast genes, and therefore the maternal line, seem to be pomelo. The sweet orange has had its genome sequenced. Earlier estimates of the percentage of pomelo genes varying from ~50% to 6% have been reported, sweet oranges were mentioned in Chinese literature in 314 BC. As of 1987, orange trees were found to be the most cultivated fruit tree in the world, orange trees are widely grown in tropical and subtropical climates for their sweet fruit. The fruit of the tree can be eaten fresh, or processed for its juice or fragrant peel. As of 2012, sweet oranges accounted for approximately 70% of citrus production, in 2014,70.9 million tonnes of oranges were grown worldwide, with Brazil producing 24% of the world total followed by China and India. All citrus trees belong to the single genus Citrus and remain almost entirely interfertile and this includes grapefruits, lemons, limes, oranges, and various other types and hybrids. The fruit of any citrus tree is considered a hesperidium, a kind of modified berry, different names have been given to the many varieties of the genus. Orange applies primarily to the sweet orange – Citrus sinensis Osbeck, the orange tree is an evergreen, flowering tree, with an average height of 9 to 10 m, although some very old specimens can reach 15 m. Its oval leaves, alternately arranged, are 4 to 10 cm long and have crenulate margins, when unripe, the fruit is green. The grainy irregular rind of the fruit can range from bright orange to yellow-orange. Like all other fruits, the sweet orange is non-climacteric. The Citrus sinensis group is subdivided into four classes with distinct characteristics, common oranges, blood or pigmented oranges, navel oranges, other citrus groups also known as oranges are, Bitter orange, also known as Seville orange, sour orange, bigarade orange and marmalade orange. Like the sweet orange, it is a pomelo x mandarin hybrid, bergamot orange, grown mainly in Italy for its peel, producing a primary essence for perfumes, also used to flavor Earl Grey tea. It is a hybrid, probably bitter orange x limetta, trifoliate orange, sometimes included in the genus

Grape
–
A grape is a fruit, botanically a berry, of the deciduous woody vines of the flowering plant genus Vitis. Grapes can be fresh as table grapes or they can be used for making wine, jam, juice, jelly, grape seed extract, raisins, vinegar. Grapes are a type of fruit, generally occurring in clusters. The cultivation of the grape began 6, 000–8,000 years ago in the Near East. Yeast, one of the earliest domesticated microorganisms, occurs naturally on the skins of grapes, the earliest archeological evidence for a dominant position of wine-making in human culture dates from 8,000 years ago in Georgia. The oldest known winery was found in Armenia, dating to around 4000 BC, by the 9th century AD the city of Shiraz was known to produce some of the finest wines in the Middle East. Thus it has proposed that Syrah red wine is named after Shiraz. Ancient Egyptian hieroglyphics record the cultivation of grapes, and history attests to the ancient Greeks, Phoenicians. The growing of grapes would later spread to regions in Europe, as well as North Africa. Vitis vinifera cultivars were imported for that purpose, Grapes are a type of fruit that grow in clusters of 15 to 300, and can be crimson, black, dark blue, yellow, green, orange, and pink. White grapes are actually green in color, and are derived from the purple grape. Mutations in two genes of white grapes turn off production of anthocyanins, which are responsible for the color of purple grapes. Anthocyanins and other pigment chemicals of the family of polyphenols in purple grapes are responsible for the varying shades of purple in red wines. Grapes are typically an ellipsoid shape resembling a prolate spheroid, most grapes come from cultivars of Vitis vinifera, the European grapevine native to the Mediterranean and Central Asia. Vitis riparia, a vine of North America, is sometimes used for winemaking. It is native to the entire Eastern U. S. Vitis rotundifolia, the muscadines, used for jams and wine, are native to the Southeastern United States from Delaware to the Gulf of Mexico. Vitis amurensis is the most important Asian species, according to the Food and Agriculture Organization,75,866 square kilometers of the world are dedicated to grapes. Approximately 71% of world production is used for wine, 27% as fresh fruit

Banana
–
The banana is an edible fruit – botanically a berry – produced by several kinds of large herbaceous flowering plants in the genus Musa. In some countries, bananas used for cooking may be called plantains, in contrast to dessert bananas. The fruit is variable in size, color and firmness, but is elongated and curved, with soft flesh rich in starch covered with a rind which may be green, yellow, red, purple. The fruits grow in clusters hanging from the top of the plant, almost all modern edible parthenocarpic bananas come from two wild species – Musa acuminata and Musa balbisiana. The scientific names of most cultivated bananas are Musa acuminata, Musa balbisiana, the old scientific name Musa sapientum is no longer used. Musa species are native to tropical Indomalaya and Australia, and are likely to have been first domesticated in Papua New Guinea. They are grown in 135 countries, primarily for their fruit, worldwide, there is no sharp distinction between bananas and plantains. Especially in the Americas and Europe, banana usually refers to soft, sweet, dessert bananas, particularly those of the Cavendish group, by contrast, Musa cultivars with firmer, starchier fruit are called plantains. In other regions, such as Southeast Asia, many kinds of banana are grown and eaten. The term banana is used as the common name for the plants which produce the fruit. This can extend to members of the genus Musa like the scarlet banana, pink banana. It can also refer to members of the genus Ensete, like the snow banana, both genera are classified under the banana family, Musaceae. The banana plant is the largest herbaceous flowering plant, all the above-ground parts of a banana plant grow from a structure usually called a corm. Plants are normally tall and fairly sturdy, and are mistaken for trees. Bananas grow in a variety of soils, as long as the soil is at least 60 cm deep, has good drainage and is not compacted. The leaves of plants are composed of a stalk and a blade. The base of the petiole widens to form a sheath, the tightly packed sheaths make up the pseudostem, the edges of the sheath meet when it is first produced, making it tubular. As new growth occurs in the centre of the pseudostem the edges are forced apart, cultivated banana plants vary in height depending on the variety and growing conditions

Arbutus unedo
–
Arbutus unedo is an evergreen shrub or small tree in the family Ericaceae, native to the Mediterranean region and western Europe north to western France and Ireland. Due to its presence in southwest and northwest Ireland, it is known as either Irish strawberry tree, or cain or cane apple, or sometimes Killarney strawberry tree. Arbutus unedo was one of the species described by Carl Linnaeus in Volume One of his landmark 1753 work Species Plantarum. It is sold in California as Arbutus x Marina named for a district in San Francisco where it was hybridized, Arbutus unedo grows to 5–10 m tall, rarely up to 15 m, with a trunk diameter of up to 80 cm. Zone, 7–10 The leaves are green and glossy, 5–10 cm long and 2–3 cm broad. The hermaphrodite flowers are white, bell-shaped, 4–6 mm diameter, the fruit is a red berry, 1–2 cm diameter, with a rough surface. It matures in about 12 months, in autumn, at the time as the next flowering. It is edible, the fruit is sweet when reddish, the name unedo is attributed to Pliny the Elder, who allegedly claimed that unum tantum edo, meaning I eat only one. It is not known whether he meant that the fruit was so good he could eat only one and it is also found in western France, Albania, Bulgaria and southwestern Ireland. The red-flowered variant, named A. unedo rubra by William Aiton in 1785, was discovered growing wild in Ireland in 1835, Arbutus unedo serves as a bee plant for honey production, and the fruits are food for birds. The fruits are used to make jams, beverages. Many regions of Albania prepare the drink raki from the fruits of the plant. In order to reduce the content of methanol in the drink. Honey produced has a bitter taste. In folk medicine, the plant has been used for antiseptic, astringent, intoxicant, rheumatism, Arbutus unedo is cultivated as an ornamental plant by plant nurseries. It is used as a single or multi-trunked ornamental tree, and as a specimen or hedge shrub in gardens, when grown as a tree rather than a shrub, basal sprouts are kept pruned off. The plant prefers well-drained soils, and low to moderate soil moisture, unlike most of the Ericaceae, A. unedo grows well in basic pH soils. In cold climates it prefers a position due to its late flowering habit

Millet
–
Millets are a group of highly variable small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Millets are important crops in the tropics of Asia and Africa. The crop is favored due to its productivity and short growing season under dry, millets are indigenous to many parts of the world. The most widely grown millet is pearl millet, which is an important crop in India, Finger millet, proso millet, and foxtail millet are also important crop species. Millets have been important food staples in human history, particularly in Asia and they have been in cultivation in East Asia for the last 10,000 years. Consumption of the minor millets has been practiced since the beginning of the ancient civilizations of the world, generally, the millets are small-grained, annual, warm-weather cereals belonging to grass family. They are highly tolerant of extreme conditions such as drought and are nutritious compared to the major cereals such as rice. They contain low phytic acid and are rich in fiber, iron, calcium. Moreover, these millets release sugar slowly in the blood and also diminish the glucose absorption, major millets are the most widely cultivated species. Eragrostideae tribe, Eleusine coracana, Finger millet - the fourth-most cultivated millet, paniceae tribe, Panicum miliaceum, Proso millet - the third-most cultivated millet. Pennisetum glaucum, Pearl millet - the most cultivated millet, setaria italica, Foxtail millet - the second-most cultivated millet. Jobs tears - of minor importance as a crop, eragrostideae tribe, Eragrostis tef, Teff - often not considered to be a millet. White fonio, Black fonio, Raishan, Polish millet - of minor importance as a crop, Japanese barnyard millet, Indian barnyard millet, Burgu millet, Common barnyard grass. Collectively, the members of this genus are called barnyard grasses or barnyard millets, other common names to identify these seeds include Jhangora, Samo seeds or Morio / Mario / Moraiaya seeds. Panicum sumatrense, Little millet Paspalum scrobiculatum, Kodo millet Urochloa ramosa, guinea millet Foxtail Millet is known to have been the first domesticated millet. Chinese legends attribute the domestication of millet to Shennong, the legendary Emperor of China, millets also formed important parts of the prehistoric diet in Indian, Chinese Neolithic and Korean Mumun societies. Broomcorn and foxtail millet were important crops beginning in the Early Neolithic of China, for example, some of the earliest evidence of millet cultivation in China was found at Cishan. Evidence at Cishan for foxtail millet dates back to around 6500 BC, a 4, 000-year-old well-preserved bowl containing well-preserved noodles made from foxtail millet and broomcorn millet was found at the Lajia archaeological site in China

Barley
–
Barley, a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains, particularly in Eurasia as early as 10,000 years ago, Barley has been used as animal fodder, as a source of fermentable material for beer and certain distilled beverages, and as a component of various health foods. It is used in soups and stews, and in barley bread of various cultures, Barley grains are commonly made into malt in a traditional and ancient method of preparation. In 2014, barley was ranked fourth among grains in quantity produced behind corn, rice, the Old English word for barley was bære, which traces back to Proto-Indo-European and is cognate to the Latin word farina flour. The direct ancestor of modern English barley in Old English was the derived adjective bærlic, the first citation of the form bærlic in the Oxford English Dictionary dates to around 966 CE, in the compound word bærlic-croft. The underived word bære survives in the north of Scotland as bere, the word barn, which originally meant barley-house, is also rooted in these words. Barley is a member of the grass family and it is a self-pollinating, diploid species with 14 chromosomes. The wild ancestor of domesticated barley, Hordeum vulgare subsp, spontaneum, is abundant in grasslands and woodlands throughout the Fertile Crescent area of Western Asia and northeast Africa, and is abundant in disturbed habitats, roadsides and orchards. Outside this region, the barley is less common and is usually found in disturbed habitats. However, in a study of genome-wide diversity markers, Tibet was found to be a center of domestication of cultivated barley. Wild barley has a spike, upon maturity, the spikelets separate. Domesticated barley has nonshattering spikes, making it easier to harvest the mature ears. The nonshattering condition is caused by a mutation in one of two linked genes known as Bt1 and Bt2, many cultivars possess both mutations. The nonshattering condition is recessive, so varieties of barley that exhibit this condition are homozygous for the mutant allele, spikelets are arranged in triplets which alternate along the rachis. In wild barley, only the central spikelet is fertile, while the two are reduced. This condition is retained in certain cultivars known as two-row barleys, a pair of mutations result in fertile lateral spikelets to produce six-row barleys. Recent genetic studies have revealed that a mutation in one gene, two-row barley has a lower protein content than six-row barley, thus a more fermentable sugar content. High-protein barley is best suited for animal feed, Malting barley is usually lower protein which shows more uniform germination, needs shorter steeping, and has less protein in the extract that can make beer cloudy

Rice
–
Rice is the seed of the grass species Oryza sativa or Oryza glaberrima. As a cereal grain, it is the most widely consumed staple food for a part of the worlds human population. It is the agricultural commodity with the third-highest worldwide production, after sugarcane and maize, wild rice, from which the crop was developed, may have its native range in Australia. Chinese legends attribute the domestication of rice to Shennong, the emperor of China. Genetic evidence has shown that rice originates from a single domestication 8, previously, archaeological evidence had suggested that rice was domesticated in the Yangtze River valley region in China. From East Asia, rice was spread to Southeast and South Asia, Rice was introduced to Europe through Western Asia, and to the Americas through European colonization. There are many varieties of rice and culinary preferences tend to vary regionally, in some areas such as the Far East or Spain, there is a preference for softer and stickier varieties. Rice, a monocot, is grown as an annual plant, although in tropical areas it can survive as a perennial. The rice plant can grow to 1–1.8 m tall, occasionally more depending on the variety and it has long, slender leaves 50–100 cm long and 2–2.5 cm broad. The small wind-pollinated flowers are produced in a branched arching to pendulous inflorescence 30–50 cm long, the edible seed is a grain 5–12 mm long and 2–3 mm thick. Rice cultivation is well-suited to countries and regions with low costs and high rainfall, as it is labor-intensive to cultivate. However, rice can be grown practically anywhere, even on a hill or mountain area with the use of water-controlling terrace systems. Although its parent species are native to Asia and certain parts of Africa, centuries of trade, the traditional method for cultivating rice is flooding the fields while, or after, setting the young seedlings. The name wild rice is used for species of the genera Zizania and Porteresia. The Greek word is the source of all European words, the origin of the Greek word is unclear. It is sometimes held to be from the Tamil word அரிசி, however, Krishnamurti disagrees with the notion that Old Tamil arici is the source of the Greek term, and proposes that it was borrowed from descendants of Proto-Dravidian *wariñci instead. The varieties of rice are typically classified as long-, medium-, the grains of long-grain rice tend to remain intact after cooking, medium-grain rice becomes more sticky. Medium-grain rice is used for dishes, for risotto in Italy

Cassava
–
Manihot esculenta is a woody shrub native to South America of the spurge family, Euphorbiaceae. It is extensively cultivated as a crop in tropical and subtropical regions for its edible starchy tuberous root. Though it is often called yuca in Spanish and in the United States, it differs from the yucca, Cassava, when dried to a powdery extract, is called tapioca, its fermented, flaky version is named garri. Cassava is the third-largest source of carbohydrates in the tropics, after rice. Cassava is a staple food in the developing world, providing a basic diet for over half a billion people. It is one of the most drought-tolerant crops, capable of growing on marginal soils, Nigeria is the worlds largest producer of cassava, while Thailand is the largest exporter of dried cassava. Cassava is classified as sweet or bitter. Like other roots and tubers, both bitter and sweet varieties of cassava contain antinutritional factors and toxins, with the bitter varieties containing much larger amounts, the more toxic varieties of cassava are a fall-back resource in times of famine or food insecurity in some places. Farmers often prefer the bitter varieties because they deter pests, animals, the cassava root is long and tapered, with a firm, homogeneous flesh encased in a detachable rind, about 1 mm thick, rough and brown on the outside. Commercial cultivars can be 5 to 10 cm in diameter at the top, a woody vascular bundle runs along the roots axis. The flesh can be chalk-white or yellowish, Cassava roots are very rich in starch and contain small amounts of calcium, phosphorus, and vitamin C. However, they are poor in protein and other nutrients, in contrast, cassava leaves are a good source of protein, but deficient in the amino acid methionine and possibly tryptophan. Forms of the domesticated species can also be found growing in the wild in the south of Brazil. By 4,600 BC, manioc pollen appears in the Gulf of Mexico lowlands, the oldest direct evidence of cassava cultivation comes from a 1, 400-year-old Maya site, Joya de Cerén, in El Salvador. With its high potential, it had become a staple food of the native populations of northern South America, southern Mesoamerica. Cassava was a food of pre-Columbian peoples in the Americas and is often portrayed in indigenous art. The Moche people often depicted yuca in their ceramics, spaniards in their early occupation of Caribbean islands did not want to eat cassava or maize, which they considered insubstantial, dangerous, and not nutritious. They much preferred foods from Spain, specifically wheat bread, olive oil, red wine, and meat, for these Christians in the New World, cassava was not suitable for communion since it could not undergo transubstantiation and become the body of Christ
11.
Potato
–
The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. The word potato may refer either to the plant itself or to the edible tuber, in the Andes, where the species is indigenous, there are some other closely related cultivated potato species. Potatoes were introduced to Europe in the half of the 16th century by the Spanish. It is the worlds fourth-largest food crop, following maize, wheat, the green leaves and green skins of tubers exposed to the light are toxic. Wild potato species can be throughout the Americas from the United States to southern Chile. Following centuries of breeding, there are now over a thousand different types of potatoes. However, the importance of the potato is variable and changing rapidly. As of 2007 China led the world in production, and nearly a third of the worlds potatoes were harvested in China. The English word potato comes from Spanish patata, the Spanish Royal Academy says the Spanish word is a compound of the Taíno batata and the Quechua papa. The 16th-century English herbalist John Gerard used the terms bastard potatoes and Virginia potatoes for this species, potatoes are occasionally referred to as Irish potatoes or white potatoes in the United States, to distinguish them from sweet potatoes. The name spud for a small potato comes from the digging of soil prior to the planting of potatoes, the word spud traces back to the 16th century. It subsequently transferred over to a variety of digging tools, around 1845, the name transferred to the tuber itself. It was Mario Peis 1949 The Story of Language that can be blamed for the false origin. Pei writes, the potato, for its part, was in disrepute some centuries ago, some Englishmen who did not fancy potatoes formed a Society for the Prevention of Unwholesome Diet. The initials of the words in this title gave rise to spud. Like most other pre-20th century acronymic origins, this is false, Potato plants are herbaceous perennials that grow about 60 cm high, depending on variety, with the leaves dying back after flowering, fruiting and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens, in general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bumblebees, which carry pollen from other potato plants, tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties

Sugarcane
–
It has stout, jointed, fibrous stalks that are rich in the sugar sucrose, which accumulates in the stalk internodes. The plant is two to six meters tall, all sugar cane species interbreed and the major commercial cultivars are complex hybrids. Sugarcane belongs to the grass family Poaceae, an important seed plant family that includes maize, wheat, rice, and sorghum. Sucrose, extracted and purified in specialized factories, is used as raw material in the food industry or is fermented to produce ethanol. Ethanol is produced on a large scale by the Brazilian sugarcane industry, sugarcane is the worlds largest crop by production quantity. In 2012, The Food and Agriculture Organization estimates it was cultivated on about 26×106 hectares, in more than 90 countries, Brazil was the largest producer of sugar cane in the world. The next five major producers, in decreasing amounts of production, were India, China, Thailand, Pakistan, the world demand for sugar is the primary driver of sugarcane agriculture. Cane accounts for 80% of sugar produced, most of the rest is made from sugar beets, sugarcane predominantly grows in the tropical and subtropical regions. Other than sugar, products derived from sugarcane include falernum, molasses, rum, cachaça, bagasse, in some regions, people use sugarcane reeds to make pens, mats, screens, and thatch. The young, unexpanded inflorescence of tebu telor is eaten raw, steamed, or toasted, the Persians, followed by the Greeks, discovered the famous reeds that produce honey without bees in India between the 6th and 4th centuries BC. They adopted and then spread sugarcane agriculture, merchants began to trade in sugar from India, which was considered a luxury and an expensive spice. Sugarcane is a tropical, perennial grass that forms lateral shoots at the base to produce multiple stems, the stems grow into cane stalk, which when mature constitutes around 75% of the entire plant. A mature stalk is composed of 11–16% fiber, 12–16% soluble sugars, 2–3% nonsugars. A sugarcane crop is sensitive to the climate, soil type, irrigation, fertilizers, insects, disease control, varieties, the average yield of cane stalk is 60–70 tonnes per hectare per year. However, this figure can vary between 30 and 180 tonnes per hectare depending on knowledge and crop management approach used in sugarcane cultivation, sugarcane is a cash crop, but it is also used as livestock fodder. Sugarcane is indigenous to tropical South and Southeast Asia, different species likely originated in different locations, with Saccharum barberi originating in India and S. edule and S. officinarum in New Guinea. It is theorized that sugarcane was first domesticated as a crop in New Guinea around 6000 BC, New Guinean farmers and other early cultivators of sugarcane chewed the plant for its sweet juice. The exact date of the first cane sugar production is unclear, the earliest evidence of sugar production comes from ancient Sanskrit and Pali texts
listen); Basque: pattar [paˈcar]; Catalan: aiguardent [ˌajɣwəɾˈðen]; Galician: augardente [awɣaɾˈðente]; Portuguese: aguardente [aɣwɐɾˈðẽt(ɨ)]/[agwɐʁˈdẽtʃi]) is a generic term for alcoholic beverages that contain between 29% and 60% alcohol by volume. The word is a compound of the Romance languages' words for "water" (agua in Spanish; aigua in Catalan; água in Portuguese; auga in Galician) and "fiery" (ardiente in Spanish; ardent in Catalan; ardente in Portuguese and Galician), similarly to the English term "firewater". Both aguardiente and brandy—from the Dutch expression for "burnt (i.e., distilled) wine"—originated as terms for distilled spirits using whatever ingredients were available locally.
