111-471: Human habitation in the area where Kamennogorsk now stands goes back to the Stone Age . In the beginning of the 20th century, a Stone Age site was discovered under a layer of peat . Findings at the site included wooden and flint implements, polished instruments of shale, remains of net of nettle fibers, sixteen fishing floats of piny bark, thirty-one stone plummets, a long bone dagger, and remains of nets with

222-401: A cultivated variety of Beta vulgaris in the family Amaranthaceae , the tuberous root of which contains a high proportion of sucrose. It is cultivated as a root crop in temperate regions with adequate rainfall and requires a fertile soil. The crop is harvested mechanically in the autumn and the crown of leaves and excess soil removed. The roots do not deteriorate rapidly and may be left in

333-671: A municipal division , Kamennogorskoye Settlement Municipal Formation is incorporated within Vyborgsky Municipal District as Kamennogorskoye Urban Settlement . A large quarry for extraction of grey granite is situated in Kamennogorsk. Also there is an offset paper factory, which before the war was used for producing sugar from sugar beets . The town has a railway station on the railway line connecting Vyborg and Khiytola (the old Vyborg–Joensuu railroad ). Another railway branches up north to Svetogorsk ;

444-760: A conference in anthropology held by the Wenner-Gren Foundation, at Burg Wartenstein Castle, which it then owned in Austria, attended by the same scholars that attended the Pan African Congress, including Louis Leakey and Mary Leakey , who was delivering a pilot presentation of her typological analysis of Early Stone Age tools, to be included in her 1971 contribution to Olduvai Gorge , "Excavations in Beds I and II, 1960–1963." However, although

555-494: A diet high in free sugar, especially refined sugar, was damaging to human health . In 2015, the World Health Organization strongly recommended that adults and children reduce their intake of free sugars to less than 10% of their total energy intake and encouraged a reduction to below 5%. In general, high sugar consumption damages human health more than it provides nutritional benefit and is associated with

666-420: A hammerstone to obtain large and small pieces with one or more sharp edges. The original stone is called a core; the resultant pieces, flakes. Typically, but not necessarily, small pieces are detached from a larger piece, in which case the larger piece may be called the core and the smaller pieces the flakes . The prevalent usage, however, is to call all the results flakes, which can be confusing. A split in half

777-530: A length of 27 meters (89 ft) and a width of up to 3 meters (9.8 ft). In the 14th-17th centuries, Antrea was a main administrative center of Karelian settlements on the upper Vuoksi. The name comes from Lutheran community founded in the 17th century and the church of St. Andrew . In 1710, during the Great Northern War , the troops of Tsar Peter the Great included the whole area of

888-576: A negligible amount of iron or any other nutrient. Because brown sugar contains 5–10% molasses reintroduced during processing, its value to some consumers is a richer flavor than white sugar. High sugar consumption damages human health more than it provides nutritional benefit, and in particular is associated with a risk of cardiometabolic health detriments. Sugar refiners and manufacturers of sugary foods and drinks have sought to influence medical research and public health recommendations, with substantial and largely clandestine spending documented from

999-782: A new Lower Paleolithic tool, the hand axe, appeared. The earliest European hand axes are assigned to the Abbevillian industry , which developed in northern France in the valley of the Somme River ; a later, more refined hand-axe tradition is seen in the Acheulian industry , evidence of which has been found in Europe, Africa, the Middle East, and Asia. Some of the earliest known hand axes were found at Olduvai Gorge (Tanzania) in association with remains of H. erectus . Alongside

1110-633: A result of the Winter War . It was recaptured by Finns between 1941 and 1944 during Continuation War but was again ceded to the Soviet Union after Moscow Armistice . This secession was formalized after signing Paris Peace Treaty in 1947. The population was resettled to Finland, and population from Central Russia was resettled to populate the Karelian Isthmus. In 1940, Antrea became a part of newly established Yaskinsky District with

1221-522: A risk of cardiometabolic and other health detriments. The etymology of sugar reflects the commodity's spread. From Sanskrit śarkarā , meaning "ground or candied sugar", came Persian shakar and Arabic sukkar . The Arabic word was borrowed in Medieval Latin as succarum , whence came the 12th century French sucre and the English sugar . Sugar was introduced into Europe by

1332-606: A separate Copper Age or Bronze Age. Moreover, the technologies included in those 'stages', as Goodwin called them, were not exactly the same. Since then, the original relative terms have become identified with the technologies of the Paleolithic and Mesolithic, so that they are no longer relative. Moreover, there has been a tendency to drop the comparative degree in favor of the positive: resulting in two sets of Early, Middle and Late Stone Ages of quite different content and chronologies. By voluntary agreement, archaeologists respect

1443-451: A sweet taste but are not classified as sugar. Sugars are found in the tissues of most plants. Honey and fruits are abundant natural sources of simple sugars. Sucrose is especially concentrated in sugarcane and sugar beet , making them ideal for efficient commercial extraction to make refined sugar. In 2016, the combined world production of those two crops was about two billion tonnes . Maltose may be produced by malting grain. Lactose

1554-786: A time known as the Copper Age (or more technically the Chalcolithic or Eneolithic, both meaning 'copper–stone'). The Chalcolithic by convention is the initial period of the Bronze Age. The Bronze Age was followed by the Iron Age . The transition out of the Stone Age occurred between 6000 and 2500  BC for much of humanity living in North Africa and Eurasia . The first evidence of human metallurgy dates to between

1665-440: A very limited extent, though ruminants can do so with the help of symbiotic bacteria in their gut. DNA and RNA are built up of the monosaccharides deoxyribose and ribose , respectively. Deoxyribose has the formula C 5 H 10 O 4 and ribose the formula C 5 H 10 O 5 . Because sugars burn easily when exposed to flame, the handling of sugars risks dust explosion . The risk of explosion

1776-415: A whiter product. About 2,500 litres (660 US gal) of irrigation water is needed for every one kilogram (2.2 pounds) of sugar produced. In 2020, global production of sugar beets was 253 million tonnes , led by Russia with 13% of the world total (table). Sugar beet became a major source of sugar in the 19th century when methods for extracting the sugar became available. It is a biennial plant ,

1887-565: A wide range of techniques derived from multiple fields. The work of archaeologists in determining the paleocontext and relative sequence of the layers is supplemented by the efforts of geologic specialists in identifying layers of rock developed or deposited over geologic time; of paleontological specialists in identifying bones and animals; of palynologists in discovering and identifying pollen, spores and plant species; of physicists and chemists in laboratories determining ages of materials by carbon-14 , potassium-argon and other methods. The study of

1998-421: Is a refined form of sucrose. In the body, compound sugars are hydrolysed into simple sugars. Longer chains of monosaccharides (>2) are not regarded as sugars and are called oligosaccharides or polysaccharides . Starch is a glucose polymer found in plants, the most abundant source of energy in human food . Some other chemical substances, such as ethylene glycol , glycerol and sugar alcohols , may have

2109-478: Is any of several species, or their hybrids, of giant grasses in the genus Saccharum in the family Poaceae . They have been cultivated in tropical climates in the Indian subcontinent and Southeast Asia over centuries for the sucrose found in their stems. Sugar cane requires a frost-free climate with sufficient rainfall during the growing season to make full use of the plant's substantial growth potential. The crop

2220-535: Is associated with the remains of Neanderthal man . The earliest documented stone tools have been found in eastern Africa, manufacturers unknown, at the 3.3 million-year-old site of Lomekwi 3 in Kenya. Better known are the later tools belonging to an industry known as Oldowan , after the type site of Olduvai Gorge in Tanzania. The tools were formed by knocking pieces off a river pebble, or stones like it, with

2331-542: Is called bipolar flaking. Consequently, the method is often called "core-and-flake". More recently, the tradition has been called "small flake" since the flakes were small compared to subsequent Acheulean tools . The essence of the Oldowan is the making and often immediate use of small flakes. Another naming scheme is "Pebble Core Technology (PBC)": Pebble cores are ... artifacts that have been shaped by varying amounts of hard-hammer percussion. Various refinements in

2442-489: Is due to the amount of molasses they contain. They may be classified based on their darkness or country of origin. Worldwide sugar provides 10% of the daily calories (based on a 2000 kcal diet). In 1750, the average Briton got 72 calories a day from sugar. In 1913, this had risen to 395. In 2015, sugar still provided around 14% of the calories in British diets. According to one source, per capita consumption of sugar in 2016

2553-437: Is filtered out, many of the impurities are removed at the same time. Removal of color is achieved by using either a granular activated carbon or an ion-exchange resin . The sugar syrup is concentrated by boiling and then cooled and seeded with sugar crystals, causing the sugar to crystallize out. The liquor is spun off in a centrifuge and the white crystals are dried in hot air and ready to be packaged or used. The surplus liquor

2664-444: Is harvested mechanically or by hand, chopped into lengths and conveyed rapidly to the processing plant (commonly known as a sugar mill ) where it is either milled and the juice extracted with water or extracted by diffusion. The juice is clarified with lime and heated to destroy enzymes . The resulting thin syrup is concentrated in a series of evaporators, after which further water is removed. The resulting supersaturated solution

2775-418: Is higher when the sugar has been milled to superfine texture, such as for use in chewing gum . The 2008 Georgia sugar refinery explosion , which killed 14 people and injured 36, and destroyed most of the refinery, was caused by the ignition of sugar dust. In its culinary use, exposing sugar to heat causes caramelization . As the process occurs, volatile chemicals such as diacetyl are released, producing

2886-477: Is in the nature of this boundary. If there is no distinct boundary, then the population of A suddenly stopped using the customs characteristic of A and suddenly started using those of B, an unlikely scenario in the process of evolution . More realistically, a distinct border period, the A/B transition, existed, in which the customs of A were gradually dropped and those of B acquired. If transitions do not exist, then there

2997-399: Is known as affination and involves immersing the sugar crystals in a concentrated syrup that softens and removes the sticky brown coating without dissolving them. The crystals are then separated from the liquor and dissolved in water. The resulting syrup is treated either by a carbonatation or by a phosphatation process. Both involve the precipitation of a fine solid in the syrup and when this

3108-429: Is made from raw sugar that has undergone a refining process to remove the molasses . Raw sugar is sucrose which is extracted from sugarcane or sugar beet . While raw sugar can be consumed, the refining process removes unwanted tastes and results in refined sugar or white sugar. The sugar may be transported in bulk to the country where it will be used and the refining process often takes place there. The first stage

3219-454: Is made into refiners' molasses. The International Commission for Uniform Methods of Sugar Analysis sets standards for the measurement of the purity of refined sugar, known as ICUMSA numbers; lower numbers indicate a higher level of purity in the refined sugar. Refined sugar is widely used for industrial needs for higher quality. Refined sugar is purer (ICUMSA below 300) than raw sugar (ICUMSA over 1,500). The level of purity associated with

3330-621: Is no proof of any continuity between A and B. The Stone Age of Europe is characteristically in deficit of known transitions. The 19th and early 20th-century innovators of the modern three-age system recognized the problem of the initial transition, the "gap" between the Paleolithic and the Neolithic. Louis Leakey provided something of an answer by proving that man evolved in Africa. The Stone Age must have begun there to be carried repeatedly to Europe by migrant populations. The different phases of

3441-571: Is now considered to be a facies of Acheulean , while Sangoan is a facies of Lupemban . Magosian is "an artificial mix of two different periods". Once seriously questioned, the intermediates did not wait for the next Pan African Congress two years hence, but were officially rejected in 1965 (again on an advisory basis) by Burg Wartenstein Conference #29, Systematic Investigation of the African Later Tertiary and Quaternary ,

3552-586: Is possible to speak of a general 'Stone Age' period for the whole of humanity, some groups never developed metal- smelting technology, and so remained in the so-called 'Stone Age' until they encountered technologically developed cultures. The term was innovated to describe the archaeological cultures of Europe. It may not always be the best in relation to regions such as some parts of the Indies and Oceania, where farmers or hunter-gatherers used stone for tools until European colonisation began. Archaeologists of

3663-414: Is seeded with sugar crystals, facilitating crystal formation and drying. Molasses is a by-product of the process and the fiber from the stems, known as bagasse , is burned to provide energy for the sugar extraction process. The crystals of raw sugar have a sticky brown coating and either can be used as they are, can be bleached by sulfur dioxide , or can be treated in a carbonatation process to produce

3774-420: Is sometimes used as a sweetener for foods (e.g., toast and cereal) and beverages (e.g., coffee and tea). The average person consumes about 24 kilograms (53 pounds) of sugar each year. North and South Americans consume up to 50 kg (110 lb), and Africans consume under 20 kg (44 lb). As free sugar consumption grew in the latter part of the 20th century, researchers began to examine whether

3885-529: Is still used locally to make desserts today. Sugarcane is native of tropical areas such as the Indian subcontinent (South Asia) and Southeast Asia. Different species seem to have originated from different locations; Saccharum barberi originated in India, and S. edule and S. officinarum came from New Guinea . One of the earliest historical references to sugarcane is in Chinese manuscripts dating to

3996-439: Is the only sugar that cannot be extracted from plants. It can only be found in milk, including human breast milk, and in some dairy products . A cheap source of sugar is corn syrup , industrially produced by converting corn starch into sugars, such as maltose, fructose and glucose. Sucrose is used in prepared foods (e.g., cookies and cakes), is sometimes added to commercially available ultra-processed food and beverages, and

4107-648: The 6th and 5th millennia  BC in the archaeological sites of the Vinča culture , including Majdanpek , Jarmovac , Pločnik , Rudna Glava in modern-day Serbia. Ötzi the Iceman , a mummy from about 3300 BC, carried with him a copper axe and a flint knife. In some regions, such as Sub-Saharan Africa , the Stone Age was followed directly by the Iron Age. The Middle East and Southeast Asian regions progressed past Stone Age technology around 6000 BC. Europe, and

The chronologic basis for the definition was entirely relative. With the arrival of scientific means of finding an absolute chronology, the two intermediates turned out to be will-of-the-wisps . They were in fact Middle and Lower Paleolithic . Fauresmith

4329-605: The Khyber Pass and caravan routes. It was not plentiful or cheap in early times, and in most parts of the world, honey was more often used for sweetening. Originally, people chewed raw sugarcane to extract its sweetness. Even after refined sugarcane became more widely available during the European colonial era, palm sugar was preferred in Java and other sugar producing parts of southeast Asia, and along with coconut sugar ,

4440-440: The genus Homo , and possibly by the earlier partly contemporaneous genera Australopithecus and Paranthropus . Bone tools have been discovered that were used during this period as well but these are rarely preserved in the archaeological record . The Stone Age is further subdivided by the types of stone tools in use. The Stone Age is the first period in the three-age system frequently used in archaeology to divide

4551-500: The geologic time scale : The succession of these phases varies enormously from one region (and culture ) to another. The Paleolithic or Palaeolithic (from Greek: παλαιός, palaios , "old"; and λίθος, lithos , "stone" lit. "old stone", coined by archaeologist John Lubbock and published in 1865) is the earliest division of the Stone Age. It covers the greatest portion of humanity's time (roughly 99% of "human technological history", where "human" and "humanity" are interpreted to mean

Sometimes such words may also refer to any types of carbohydrates soluble in water. The acyclic mono- and disaccharides contain either aldehyde groups or ketone groups. These carbon-oxygen double bonds (C=O) are the reactive centers. All saccharides with more than one ring in their structure result from two or more monosaccharides joined by glycosidic bonds with

4773-454: The 12th century, the Republic of Venice acquired some villages near Tyre and set up estates to produce sugar for export to Europe. It supplemented the use of honey, which had previously been the only available sweetener. Crusade chronicler William of Tyre , writing in the late 12th century, described sugar as "very necessary for the use and health of mankind". In the 15th century, Venice

The results of research on the health effects of sugary food and drink differ significantly, depending on whether the researcher has financial ties to the food and drink industry. A 2013 medical review concluded that "unhealthy commodity industries should have no role in the formation of national or international NCD [ non-communicable disease ] policy". Similar efforts to steer coverage of sugar-related health information have been made in popular media, including news media and social media. A 2003 technical report by

4995-680: The 8th century BCE, which state that the use of sugarcane originated in India. In the tradition of Indian medicine ( āyurveda ), sugarcane is known by the name Ikṣu , and sugarcane juice is known as Phāṇita . Its varieties, synonyms and characteristics are defined in nighaṇṭus such as the Bhāvaprakāśa (1.6.23, group of sugarcanes). Sugar remained relatively unimportant until the Indians discovered methods of turning sugarcane juice into granulated crystals that were easier to store and transport. The Greek physician Pedanius Dioscorides attested to

5106-678: The Arabs in Sicily and Spain. The English word jaggery , a coarse brown sugar made from date palm sap or sugarcane juice, has a similar etymological origin: Portuguese jágara from the Malayalam cakkarā , which is from the Sanskrit śarkarā . Sugar has been produced in the Indian subcontinent for thousands of years. Sugarcane cultivation spread from there into China via

5217-615: The Elder also described sugar in his 1st century CE Natural History : " Sugar is made in Arabia as well, but Indian sugar is better. It is a kind of honey found in cane, white as gum, and it crunches between the teeth. It comes in lumps the size of a hazelnut. Sugar is used only for medical purposes. " Crusaders brought sugar back to Europe after their campaigns in the Holy Land , where they encountered caravans carrying "sweet salt". Early in

Clark regarded the Three-age System as valid for North Africa; in sub-Saharan Africa, the Three-stage System was best. In practice, the failure of African archaeologists either to keep this distinction in mind, or to explain which one they mean, contributes to the considerable equivocation already present in

5439-521: The Stone Age ended in a given area. In Europe and North America, millstones were in use until well into the 20th century, and still are in many parts of the world. The terms "Stone Age", "Bronze Age", and "Iron Age" are not intended to suggest that advancements and time periods in prehistory are only measured by the type of tool material, rather than, for example, social organization , food sources exploited, adaptation to climate, adoption of agriculture, cooking, settlement , and religion. Like pottery ,

5550-407: The Stone Age has never been limited to stone tools and archaeology, even though they are important forms of evidence. The chief focus of study has always been on the society and the living people who belonged to it. Useful as it has been, the concept of the Stone Age has its limitations. The date range of this period is ambiguous, disputed, and variable, depending upon the region in question. While it

5661-649: The Stone Age thus could appear there without transitions. The burden on African archaeologists became all the greater, because now they must find the missing transitions in Africa. The problem is difficult and ongoing. After its adoption by the First Pan African Congress in 1947, the Three-Stage Chronology was amended by the Third Congress in 1955 to include a First Intermediate Period between Early and Middle, to encompass

6216-479: The characteristic caramel flavor. Fructose, galactose, and glucose are all simple sugars, monosaccharides, with the general formula C 6 H 12 O 6 . They have five hydroxyl groups (−OH) and a carbonyl group (C=O) and are cyclic when dissolved in water. They each exist as several isomers with dextro- and laevo-rotatory forms that cause polarized light to diverge to the right or the left. Lactose, maltose, and sucrose are all compound sugars, disaccharides, with

In Europe, the Clactonian industry is one example of a flake tradition. The early flake industries probably contributed to the development of the Middle Paleolithic flake tools of the Mousterian industry , which

In 1859 Jens Jacob Worsaae first proposed a division of the Stone Age into older and younger parts based on his work with Danish kitchen middens that began in 1851. In the subsequent decades this simple distinction developed into the archaeological periods of today. The major subdivisions of the Three-age Stone Age cross two epoch boundaries on

By then, the dates of the Early Stone Age, or Paleolithic , and Late Stone Age, or Neolithic ( neo = new), were fairly solid and were regarded by Goodwin as absolute. He therefore proposed a relative chronology of periods with floating dates, to be called the Earlier and Later Stone Age. The Middle Stone Age would not change its name, but it would not mean Mesolithic . The duo thus reinvented

8325-638: The late 19th and early 20th centuries CE, who adapted the three-age system to their ideas, hoped to combine cultural anthropology and archaeology in such a way that a specific contemporaneous tribe could be used to illustrate the way of life and beliefs of the people exercising a particular Stone-Age technology. As a description of people living today, the term Stone Age is controversial. The Association of Social Anthropologists discourages this use, asserting: To describe any living group as 'primitive' or 'Stone Age' inevitably implies that they are living representatives of some earlier stage of human development that

8436-579: The literature. There are in effect two Stone Ages, one part of the Three-age and the other constituting the Three-stage. They refer to one and the same artifacts and the same technologies, but vary by locality and time. The three-stage system was proposed in 1929 by Astley John Hilary Goodwin, a professional archaeologist, and Clarence van Riet Lowe , a civil engineer and amateur archaeologist, in an article titled "Stone Age Cultures of South Africa" in

8547-420: The majority of humankind has left behind. In the 1920s, South African archaeologists organizing the stone tool collections of that country observed that they did not fit the newly detailed Three-Age System. In the words of J. Desmond Clark : It was early realized that the threefold division of culture into Stone, Bronze and Iron Ages adopted in the nineteenth century for Europe had no validity in Africa outside

8658-512: The meal, but later they become merely table decorations, the most elaborate called trionfi . Several significant sculptors are known to have produced them; in some cases their preliminary drawings survive. Early ones were in brown sugar, partly cast in molds, with the final touches carved. They continued to be used until at least the Coronation Banquet for Edward VII of the United Kingdom in 1903; among other sculptures every guest

8769-403: The method in his 1st century CE medical treatise De Materia Medica : There is a kind of coalesced honey called sakcharon [i.e. sugar] found in reeds in India and Eudaimon Arabia similar in consistency to salt and brittle enough to be broken between the teeth like salt, In the local Indian language, these crystals were called khanda ( Devanagari : खण्ड, Khaṇḍa ), which is the source of

8880-480: The modern Vyborgsky District to Russia. In the course of Peter's second administrative reform , Antrea became a part of Vyborg Province of St. Petersburg Governorate . The 1721 Treaty of Nystad , which concluded the war with Sweden, finalized the transfer of this part of Old Finland to Russia. In 1744, Vyborg Governorate , with the seat in Vyborg , was established. After several changes, Vyborg Governorate

8991-526: The molecules in the open-chain form. Biopolymers of sugars are common in nature. Through photosynthesis, plants produce glyceraldehyde-3-phosphate (G3P), a phosphated 3-carbon sugar that is used by the cell to make monosaccharides such as glucose ( C 6 H 12 O 6 ) or (as in cane and beet) sucrose ( C 12 H 22 O 11 ). Monosaccharides may be further converted into structural polysaccharides such as cellulose and pectin for cell wall construction or into energy reserves in

9102-466: The most striking circumstances about these sites is that they are from the Late Pliocene , where prior to their discovery tools were thought to have evolved only in the Pleistocene . Excavators at the locality point out that: ... the earliest stone tool makers were skilled flintknappers  ... The possible reasons behind this seeming abrupt transition from the absence of stone tools to

9213-507: The north coast of Brazil, Demarara , and Surinam . It took until 1600 for Brazilian sugar production to exceed that of São Tomé , which was the main center of sugar production in sixteenth century. Sugar was a luxury in Europe until the early 19th century, when it became more widely available, due to the rise of beet sugar in Prussia , and later in France under Napoleon . Beet sugar

9324-532: The oldest evidence of hominin use of tools known to date, have indicated that Kenyanthropus platyops (a 3.2 to 3.5-million-year-old Pliocene hominin fossil discovered in Lake Turkana, Kenya, in 1999) may have been the earliest tool-users known. The oldest stone tools were excavated from the site of Lomekwi 3 in West Turkana , northwestern Kenya, and date to 3.3 million years old. Prior to

9435-626: The presence thereof include ... gaps in the geological record. The species that made the Pliocene tools remains unknown. Fragments of Australopithecus garhi , Australopithecus aethiopicus , and Homo , possibly Homo habilis , have been found in sites near the age of the Gona tools. In July 2018, scientists reported the discovery in China of the known oldest stone tools outside Africa, estimated at 2.12 million years old. Innovation in

9546-581: The primates evolved. The rift served as a conduit for movement into southern Africa and also north down the Nile into North Africa and through the continuation of the rift in the Levant to the vast grasslands of Asia. Starting from about 4 million years ago ( mya ) a single biome established itself from South Africa through the rift, North Africa, and across Asia to modern China. This has been called "transcontinental 'savannahstan ' " recently. Starting in

9657-402: The principal monosaccharides present in the blood and internal tissues include glucose, fructose, and galactose. Many pentoses and hexoses can form ring structures . In these closed-chain forms, the aldehyde or ketone group remains non-free, so many of the reactions typical of these groups cannot occur. Glucose in solution exists mostly in the ring form at equilibrium , with less than 0.1% of

9768-605: The remains of what may have been the earliest human ancestors. A somewhat more sophisticated Lower Paleolithic tradition, known as the Chopper chopping tool industry, is widely distributed in the Eastern Hemisphere. This tradition is thought to have been the work of the hominin species named Homo erectus . Although no such fossil tools have yet been found, it is believed that H. erectus probably made tools of wood and bone as well as stone. About 700,000 years ago,

9879-487: The rest of Asia became post-Stone Age societies by about 4000 BC. The proto-Inca cultures of South America continued at a Stone Age level until around 2000 BC, when gold, copper, and silver made their entrance. The peoples of the Americas notably did not develop a widespread behavior of smelting bronze or iron after the Stone Age period, although the technology existed. Stone tool manufacture continued even after

9990-407: The resultant loss of a molecule of water ( H 2 O ) per bond. Monosaccharides in a closed-chain form can form glycosidic bonds with other monosaccharides, creating disaccharides (such as sucrose ) and polysaccharides (such as starch or cellulose ). Enzymes must hydrolyze or otherwise break these glycosidic bonds before such compounds become metabolized . After digestion and absorption

10101-486: The scientific study of the lithic reduction of the raw materials and methods used to make the prehistoric artifacts that are discovered. Much of this study takes place in the laboratory in the presence of various specialists. In experimental archaeology , researchers attempt to create replica tools, to understand how they were made. Flintknappers are craftsmen who use sharp tools to reduce flintstone to flint tool . In addition to lithic analysis, field prehistorians use

10212-516: The seventh century. Chinese documents confirm at least two missions to India, initiated in 647 CE, to obtain technology for sugar refining. Nearchus , admiral of Alexander the Great , knew of sugar during the year 325 BC because of his participation in the campaign of India led by Alexander ( Arrian , Anabasis ). In addition to the Greek physician Pedanius Dioscorides , the Roman Pliny

10323-740: The shape have been called choppers, discoids, polyhedrons, subspheroid, etc. To date no reasons for the variants have been ascertained: From a functional standpoint, pebble cores seem designed for no specific purpose. Sugar This is an accepted version of this page Sugar is the generic name for sweet-tasting , soluble carbohydrates , many of which are used in food. Simple sugars, also called monosaccharides , include glucose , fructose , and galactose . Compound sugars, also called disaccharides or double sugars, are molecules made of two bonded monosaccharides; common examples are sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (two molecules of glucose). White sugar

10434-461: The technique of smelting ore is regarded as the end of the Stone Age and the beginning of the Bronze Age . The first highly significant metal manufactured was bronze , an alloy of copper and tin or arsenic , each of which was smelted separately. The transition from the Stone Age to the Bronze Age was a period during which modern people could smelt copper, but did not yet manufacture bronze,

10545-533: The timeline of human technological prehistory into functional periods, with the next two being the Bronze Age and the Iron Age , respectively. The Stone Age is also commonly divided into three distinct periods: the earliest and most primitive being the Paleolithic era; a transitional period with finer tools known as the Mesolithic era; and the final stage known as the Neolithic era. Neolithic peoples were

10656-450: The transitions in archaeology is a branch of the general philosophic continuity problem, which examines how discrete objects of any sort that are contiguous in any way can be presumed to have a relationship of any sort. In archaeology, the relationship is one of causality . If Period B can be presumed to descend from Period A, there must be a boundary between A and B, the A–B boundary. The problem

10767-472: The typology of the stone tools combined with the relative sequence of the types in various regions provide a chronological framework for the evolution of humanity and society. They serve as diagnostics of date, rather than characterizing the people or the society. Lithic analysis is a major and specialised form of archaeological investigation. It involves the measurement of stone tools to determine their typology, function and technologies involved. It includes

10878-620: The word candy . Indian sailors, who carried clarified butter and sugar as supplies, introduced knowledge of sugar along the various trade routes they travelled. Traveling Buddhist monks took sugar crystallization methods to China. During the reign of Harsha (r. 606–647) in North India , Indian envoys in Tang China taught methods of cultivating sugarcane after Emperor Taizong of Tang (r. 626–649) made known his interest in sugar. China established its first sugarcane plantations in

10989-535: Was abolished , the demand for workers in European colonies in the Caribbean was filled by indentured laborers from the Indian subcontinent . Millions of enslaved or indentured laborers were brought to various European colonies in the Americas, Africa and Asia (as a result of demand in Europe for among other commodities, sugar), influencing the ethnic mixture of numerous nations around the globe. Sugar also led to some industrialization of areas where sugar cane

11100-429: Was 186 Mt, and in 2023/4 an estimated 194 Mt - a surplus of 5 Mt, according to Ragus . Sugar cane accounted for around 21% of the global crop production over the 2000–2021 period. The Americas was the leading region in the production of sugar cane (52% of the world total). Global production of sugarcane in 2020 was 1.9 billion tonnes, with Brazil producing 40% of the world total and India 20% (table). Sugarcane

11211-483: Was a German invention, since, in 1747, Andreas Sigismund Marggraf announced the discovery of sugar in beets and devised a method using alcohol to extract it. Marggraf's student, Franz Karl Achard , devised an economical industrial method to extract the sugar in its pure form in the late 18th century. Achard first produced beet sugar in 1783 in Kaulsdorf , and in 1801, the world's first beet sugar production facility

11322-458: Was a broad prehistoric period during which stone was widely used to make stone tools with an edge, a point, or a percussion surface. The period lasted for roughly 3.4 million years and ended between 4000 BC and 2000 BC, with the advent of metalworking . It therefore represents nearly 99.3% of human history. Though some simple metalworking of malleable metals, particularly the use of gold and copper for purposes of ornamentation,

11433-522: Was another early manufacturer of sugar cubes at his refineries in Liverpool and London. Tate purchased a patent for sugar-cube manufacture from German Eugen Langen , who in 1872 had invented a different method of processing of sugar cubes. Sugar was rationed during World War I , though it was said that "No previous war in history has been fought so largely on sugar and so little on alcohol", and more sharply during World War II . Rationing led to

11544-599: Was established in Cunern , Silesia (then part of Prussia, now Poland ). The works of Marggraf and Achard were the starting point for the sugar industry in Europe, and for the modern sugar industry in general, since sugar was no longer a luxury product and a product almost only produced in warmer climates. Sugar became highly popular and by the 19th century, was found in every household. This evolution of taste and demand for sugar as an essential food ingredient resulted in major economic and social changes. Demand drove, in part,

11655-845: Was given a sugar crown to take away. In August 1492, Christopher Columbus collected sugar cane samples in La Gomera in the Canary Islands , and introduced it to the New World . The cuttings were planted and the first sugar-cane harvest in Hispaniola took place in 1501. Many sugar mills had been constructed in Cuba and Jamaica by the 1520s. The Portuguese took sugar cane to Brazil. By 1540, there were 800 cane-sugar mills in Santa Catarina Island and another 2,000 on

11766-799: Was grown. For example, in the 1790s Lieutenant J. Paterson, of the Bengal Presidency promoted to the British parliament the idea that sugar cane could grow in British India , where it had started, with many advantages and at less expense than in the West Indies . As a result, sugar factories were established in Bihar in eastern India. During the Napoleonic Wars , sugar-beet production increased in continental Europe because of

11877-566: Was highest in the United States, followed by Germany and the Netherlands. Brown and white granulated sugar are 97% to nearly 100% carbohydrates, respectively, with less than 2% water, and no dietary fiber, protein or fat (table). Brown sugar contains a moderate amount of iron (15% of the Reference Daily Intake in a 100 gram amount, see table), but a typical serving of 4 grams (one teaspoon), would provide 15 calories and

11988-607: Was known in the Stone Age, it is the melting and smelting of copper that marks the end of the Stone Age. In Western Asia , this occurred by about 3000 BC, when bronze became widespread. The term Bronze Age is used to describe the period that followed the Stone Age, as well as to describe cultures that had developed techniques and technologies for working copper alloys (bronze: originally copper and arsenic, later copper and tin) into tools, supplanting stone in many uses. Stone Age artifacts that have been discovered include tools used by modern humans, by their predecessor species in

12099-459: Was more usually sold in bags. Sugar cubes were produced in the nineteenth century. The first inventor of a process to produce sugar in cube form was Jakob Christof Rad , director of a sugar refinery in Dačice . In 1841, he produced the first sugar cube in the world. He began sugar-cube production after being granted a five-year patent for the process on 23 January 1843. Henry Tate of Tate & Lyle

12210-745: Was renamed Finland Governorate in 1802. In 1812, it was renamed back and included in the Grand Duchy of Finland , which was previously ceded to Russia by Sweden. In Finland, it became known as the Viipuri Province . In 1918, the Viipuri Province became a part of independent Finland . Antrea, together with the rest of the Karelian Isthmus, was ceded by Finland to the Soviet Union by the Moscow Peace Treaty as

12321-479: Was the chief sugar refining and distribution center in Europe. There was a drastic change in the mid-15th century, when Madeira and the Canary Islands were settled from Europe and sugar introduced there. After this an "all-consuming passion for sugar ... swept through society" as it became far more easily available, though initially still very expensive. By 1492, Madeira was producing over 1,400,000 kilograms (3,000,000 lb) of sugar annually. Genoa , one of
