The more toxic varieties of cassava are a fall-back resource (a "food security crop") in times of famine or food insecurity in some places. [35] This push for non-grain ethanol was further increased to a goal of 300 million tons of cellulosic and non-grain based ethanol combined by 2020. [47][48], Societies that traditionally eat cassava generally understand that some processing (soaking, cooking, fermentation, etc.) For the unrelated plant, see, Species of flowering plant in the spurge family Euphorbiaceae, Tubers being grated; a close-up of the product; drying on road to be used for pig and chicken feed, CS1 maint: multiple names: authors list (, Learn how and when to remove this template message, International Institute of Tropical Agriculture, World Checklist of Selected Plant Families, "African Cassava Mosaic Virus: Etiology, Epidemiology, and Control", "Dimensions of Need: An atlas of food and agriculture", "Ch. It is used in cholent in some households. [51] The reliance on cassava as a food source and the resulting exposure to the goitrogenic effects of thiocyanate has been responsible for the endemic goiters seen in the Akoko area of southwestern Nigeria. Once harvested, bitter cassava must be treated and prepared properly prior to human or animal consumption, while sweet cassava can be used after boiling. PPD is related to the accumulation of reactive oxygen species (ROS) initiated by cyanide release during mechanical harvesting. [34] For consumption, each must be prepared and cooked as appropriate. Cassava hay contains high protein (20–27 percent crude protein) and condensed tannins (1.5–4 percent CP). ), and sweet potatoes (Ipomoea batatas) are important sources of food in the tropics. [26] Cassava is called kappa or maricheeni in Malayalam. Under the Development Plan for Renewable Energy in the Eleventh Five-Year Plan in the People's Republic of China, the target was to increase the production of ethanol fuel from nongrain feedstock to two million tonnes, and that of biodiesel to 200 thousand tonnes by 2010. Commercial cultivars can be 5 to 10 centimetres (2 to 4 inches) in diameter at the top, and around 15 to 30 cm (6 to 12 in) long. The root of the sweet variety has a delicate flavor and can replace potatoes. Cassava was introduced to Africa by Portuguese traders from Brazil in the 16th century. [58] PPD is one of the main obstacles preventing farmers from exporting cassavas abroad and generating income. [54][55], Cassava is harvested by hand by raising the lower part of the stem, pulling the roots out of the ground, and removing them from the base of the plant. The main plant-based starches made include wheat, corn, cassava and, last but not least, potato. [11], Wild populations of M. esculenta subspecies flabellifolia, shown to be the progenitor of domesticated cassava, are centered in west-central Brazil, where it was likely first domesticated no more than 10,000 years BP. Global Cassava Development Strategy, List of top international rankings by country, https://en.wikipedia.org/w/index.php?title=Cassava&oldid=1024113211, Articles with dead external links from November 2018, Articles with permanently dead external links, Short description is different from Wikidata, Pages using multiple image with manual scaled images, Articles needing additional references from August 2017, All articles needing additional references, Articles with unidentified words from August 2020, Articles with unsourced statements from December 2018, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 May 2021, at 05:39. Flour converters and nutritional values information. Cassava accounts for a daily caloric intake of 30 percent in Ghana and is grown by nearly every farming family. [39] The larger-rooted, bitter varieties used for production of flour or starch must be processed to remove the cyanogenic glucosides. [5] It is one of the most drought-tolerant crops, capable of growing on marginal soils. [18] Ships departing to Europe from Cuban ports such as Havana, Santiago, Bayamo, and Baracoa carried goods to Spain, but sailors needed to be provisioned for the voyage. The cassava plant gives the third-highest yield of carbohydrates per cultivated area among crop plants, after sugarcane and sugar beets. Cassava is predominantly consumed in boiled form, but substantial quantities are used to extract cassava starch, called tapioca, which is used for food, animal feed, and industrial purposes. peppers, pineapples, plums, guava, Mammae apple and star apples. How did the Kalinagos and Tainos differ in their customs? [6] It has also been linked to tropical calcific pancreatitis in humans, leading to chronic pancreatitis. [65], A wide range of plant parasitic nematodes have been reported associated with cassava worldwide. [64] An outbreak of the virus in Africa in the 1920s led to a major famine. This is equivalent to the replacement of 10 million tonnes of petroleum. Create your own unique website with customizable templates. Cassava, sweet potato, corn. Galls later merge as the females grow and enlarge, and they interfere with water and nutrient supply. Cassava is the third-largest source of food carbohydrates in the tropics, after rice and maize. Over 60 percent of cassava production in China is concentrated in a single province, Guangxi, averaging over seven million tonnes annually. On 22 December 2007, the largest cassava ethanol fuel production facility was completed in Beihai, with annual output of 200 thousand tons, which would need an average of 1.5 million tons of cassava. Cassava is well adapted within latitudes 30° north and south of the equator, at elevations between sea level and 2,000 m (7,000 ft) above sea level, in equatorial temperatures, with rainfalls from 50 to 5,000 mm (2 to 200 in) annually, and to poor soils with a pH ranging from acidic to alkaline. The large roots are peeled and then ground into flour, which is then soaked in water, squeezed dry several times, and toasted. [50], The traditional method used in West Africa is to peel the roots and put them into water for three days to ferment. In the humid and sub-humid areas of tropical Africa, it is either a primary staple food or a secondary costaple. First, the cassava was dug from the ground, scraped and cut into small pieces. The presence of cyanide in cassava is of concern for human and for animal consumption. [42] Excess cyanide residue from improper preparation is known to cause acute cyanide intoxication, and goiters, and has been linked to ataxia (a neurological disorder affecting the ability to walk, also known as konzo). [20] Tropical Cuban weather was not suitable for wheat planting and cassava would not go stale as quickly as regular bread. Manihot esculenta, commonly called cassava (/ k ə ˈ s ɑː v ə /), manioc, or yuca (among numerous regional names) is a woody shrub native to South America of the spurge family, Euphorbiaceae.Although a perennial plant, cassava is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrates. It can be treated easily with an injection of thiosulfate (which makes sulfur available for the patient's body to detoxify by converting the poisonous cyanide into thiocyanate). [15] Cassava was a staple food of pre-Columbian peoples in the Americas and is often portrayed in indigenous art. However, the same mechanism, which involves coumaric acids, starts about 15 minutes after damage, and fails to switch off in harvested tubers. Spaniards in their early occupation of Caribbean islands did not want to eat cassava or maize, which they considered insubstantial, dangerous, and not nutritious. Tumuhimbise GA, Namutebi A, Muyonga JH. They have not been shown to cause direct damage to the enlarged storage roots, but plants can have reduced height if there was loss of enlarged root weight. The other is Stokes Purple, a name patented by a North Carolina farmer around 2006. In contrast, cassava leaves are a good source of protein (rich in lysine), but deficient in the amino acid methionine and possibly tryptophan. It is therefore possible that extensive galling can be observed even at low densities following infection. [17] The cultivation and consumption of cassava were nonetheless continued in both Portuguese and Spanish America. [60] Plant breeding has resulted in different strategies for cassava tolerance to PPD. In Tamil Nadu, India, there are many cassava processing factories alongside National Highway 68 between Thalaivasal and Attur. [37], Cassava tubers and hay are used worldwide as animal feed. Manioc is also used in a number of commercially available laundry products, especially as starch for shirts and other garments. [67] Meloidogyne spp. These pests were rampant in the 1970s and 1980s but were brought under control following the establishment of the "Biological Control Centre for Africa" of the International Institute of Tropical Agriculture (IITA) under the leadership of Hans Rudolf Herren. Cassava shelf life may be increased up to three weeks by overexpressing a cyanide insensitive alternative oxidase, which suppressed ROS by 10-fold. Trinidad, Trinidad P., et al. [56] Bammy or cassava bread was the staple of the Tainos. The roots are then dried or cooked. Manihot esculenta, commonly called cassava (/kəˈsɑːvə/), manioc,[2] or yuca (among numerous regional names) is a woody shrub native to South America of the spurge family, Euphorbiaceae. On hydrolysis, these release hydrogen cyanide (HCN). [68] Cassava roots become tough with age and restrict the movement of the juveniles and the egg release. Nematicide use in cassava is neither practical nor sustainable; the use of tolerant and resistant cultivars is the most practical and sustainable management method. [32] Cassava must be cooked properly to detoxify it before it is eaten. The result is a foodstuff called gari. Industrial production of cassava flour, even at the cottage level, may generate enough cyanide and cyanogenic glycosides in the effluents to have a severe environmental impact. Cassava can be cooked in many ways. [9], 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. Cassava roots are very rich in starch and contain small amounts of calcium (16 mg/100 g), phosphorus (27 mg/100 g), and vitamin C (20.6 mg/100 g). Cassava is propagated by cutting the stem into sections of approximately 15 cm, these being planted prior to the wet season. is necessary to avoid getting sick. Bammy or cassava bread was the staple of the Tainos. By 4,600 BC, manioc (cassava) pollen appears in the Gulf of Mexico lowlands, at the San Andrés archaeological site. The flesh can be chalk-white or yellowish. Convert flours' weight versus volume units commonly used to measure flour amounts and translate various values into equivalent systems or new measuring units used in baking. [62] In Africa, a previous issue was the cassava mealybug (Phenacoccus manihoti) and cassava green mite (Mononychellus tanajoa). The Brazilian farinha, and the related garri of West Africa, is an edible coarse flour obtained by grating cassava roots, pressing moisture off the obtained grated pulp, and finally drying it (and roasting in the case of farinha). The African cassava mosaic virus causes the leaves of the cassava plant to wither, limiting the growth of the root. Food & Nutrition Sciences 4 (2013): 491-495. Brief soaking (four hours) of cassava is not sufficient, but soaking for 18–24 hours can remove up to half the level of cyanide. Cassava root is a starchy tuber, which means that tapioca starch has more in common with other root starches like potato starch and arrowroot than it does with a grain starch like corn starch. [22] Cassava is sometimes described as the "bread of the tropics"[23] but should not be confused with the tropical and equatorial bread tree (Encephalartos), the breadfruit (Artocarpus altilis) or the African breadfruit (Treculia africana). It offers flexibility to resource-poor farmers because it serves as either a subsistence or a cash crop.[30]. [29] Cassava plays a particularly important role in agriculture in developing countries, especially in sub-Saharan Africa, because it does well on poor soils and with low rainfall, and because it is a perennial that can be harvested as required. Its wide harvesting window allows it to act as a famine reserve and is invaluable in managing labor schedules. [60][61] One was induced by mutagenic levels of gamma rays, which putatively silenced one of the genes involved in PPD genesis, while another was a group of high-carotene clones in which the antioxidant properties of carotenoids are postulated to protect the roots from PPD.[61]. A comparative table shows that cassava is a good energy source. Cassava-based dishes are widely consumed wherever the plant is cultivated; some have regional, national, or ethnic importance. In November 2008, China-based Hainan Yedao Group invested US$51.5 million in a new biofuel facility that is expected to produce 120 million litres (33 million US gallons) a year of bioethanol from cassava plants. (Darjeeling, Sikkim, India). They much preferred foods from Spain, specifically wheat bread, olive oil, red wine, and meat, and considered maize and cassava damaging to Europeans. [65] The virus is spread by the whitefly and by the transplanting of diseased plants into new fields. above 10% of the relevant DV). Their opposing settlement location and types. [50] In that time, about 83% of the cyanogenic glycosides are broken down by the linamarase; the resulting hydrogen cyanide escapes to the atmosphere, making the flour safe for consumption the same evening. [63] The Centre investigated biological control for cassava pests; two South American natural enemies Anagyrus lopezi (a parasitoid wasp) and Typhlodromalus aripo (a predatory mite) were found to effectively control the cassava mealybug and the cassava green mite, respectively. Cassava is one of the most drought-tolerant crops, can be successfully grown on marginal soils, and gives reasonable yields where many other crops do not grow well. 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. Cassava is classified as either sweet or bitter. I am a student at The University of West Indies who is pursing my studies in the field of Computer Science but also has an interest in Caribbean History at the Csec level. The Moche people often depicted yuca in their ceramics.[16]. Cassava hay is harvested at a young growth stage (three to four months) when it reaches about 30 to 45 cm (12 to 18 in) above ground; it is then sun-dried for one to two days until its final dry matter content approaches 85 percent. Expanding the Competitive Edge in Diversified Markets", Cassava consumption and the occurrence of cyanide in cassava in Vietnam, Indonesia and Philippines, "Cassava production in 2018, Crops/World Regions/Production Quantity from pick lists", Food and Agriculture Organization Corporate Statistical Database, "Drought-tolerant Cassava for Africa, Asia, and Latin America", "The Global Cassava Development Strategy", "The Effect of Processing on the Nutrient Content of Cassava (Manihot Esculenta Crantz) Leaves", "China Biofuel Industry Faces Uncertain Future", "Cassava bio-ethanol plant to open in China", "Effect of cassava hay and rice bran oil supplementation on rumen fermentation, milk yield and milk composition in lactating dairy cows", "Linamarin: the Toxic Compound of Cassava", "Cyanogenesis in Cassava, The Role of Hydroxynitrile Lyase in Root Cyanide Production", "Opinion of the Scientific Panel on Food Additives, Flavourings, Processing Aids and Materials in Contact with Food (AFC) on hydrocyanic acid in flavourings and other food ingredients with flavouring properties", "How do people learn to cook a poisonous plant safely? The tubers, when damaged, normally respond with a healing mechanism. Other major growers were Thailand and Democratic Republic of the Congo.[27]. [31] No continent depends as much on root and tuber crops in feeding its population as does Africa. Though it is often called yuca in parts of Spanish America and in the United States, it is not related to yucca, a shrub in the family Asparagaceae. Corn flour has been important in Mesoamerican cuisine since ancient times and remains a staple in the Americas. In Ghana, for example, cassava and yams occupy an important position in the agricultural economy and contribute about 46 percent of the agricultural gross domestic product. [43][44], Symptoms of acute cyanide intoxication appear four or more hours after ingesting raw or poorly processed cassava: vertigo, vomiting, and collapse. (Brazil), kasiri (Guyana, Suriname), impala (Mozambique), masato (Peruvian Amazonia chicha), parakari or kari (Guyana), nihamanchi (South America) also known as[what language is this?] Celiac disease is a serious health issue. They feasted on over forty varieties of fish. In the subtropical region of southern China, cassava is the fifth-largest crop in terms of production, after rice, sweet potato, sugar cane, and maize. Cassava is widely cultivated and eaten as a staple food in Andhra Pradesh and in Kerala. The two have strong similarities such as the fact that they both thicken liquids effectively; however, they differ in terms of how they handle heat. The concentration of these antinutritional and unsafe glycosides varies considerably between varieties and also with climatic and cultural conditions. They also cultivated chili pepper, cassava, sweet potato, pumpkin, yampi, corn, arrowroot, coco, guava, star apple, pineapple and cashew. [39], A safe processing method known as the "wetting method" is to mix the cassava flour with water into a thick paste and then let it stand in the shade for five hours in a thin layer spread over a basket. Un libro è un insieme di fogli, stampati oppure manoscritti, delle stesse dimensioni, rilegati insieme in un certo ordine e racchiusi da una copertina.. Il libro è il veicolo più diffuso del sapere. A peaceful people, they enjoyed the undisturbed tranquility of the West Indies for approximately 2000 years. (Ecuador and Peru), ö döi (chicha de yuca, Ngäbe-Bugle, Panama), sakurá (Brazil, Suriname), and tarul ko[what language is this?] [6] It must be properly prepared before consumption, as improper preparation of cassava can leave enough residual cyanide to cause acute cyanide intoxication,[7][8] goiters, and even ataxia, partial paralysis, or death. Severe cyanide poisoning, particularly during famines, is associated with outbreaks of a debilitating, irreversible paralytic disorder called konzo and, in some cases, death. [69] Other pests and diseases can gain entry through the physical damage caused by gall formation, leading to rots. Anthropologists have found the bones and shells of the grouper, parrot fish, sturgeon, shark, lobster, oyster, conch, whelk and crab in their 'middens' or garbage heaps. Although a perennial plant, cassava is extensively cultivated as an annual crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrates. Microstructure and in vitro beta carotene bioaccessibility of heat processed orange fleshed sweet potato. A woody vascular bundle runs along the root's axis. Of particular concern are the cyanogenic glucosides of cassava (linamarin and lotaustralin). potato or tortilla chips; ... cassava; tapioca; pastas made from lentils, peas, corn, rice, or buckwheat; ... Celiac vs. sensitivity. [21] Cassava has also become an important crop in Asia. China is also the largest export market for cassava produced in Vietnam and Thailand. Comparisons between the nutrient content of cassava and other major staple foods when raw must be interpreted with caution because most staples are not edible in such forms and many are indigestible, even dangerously poisonous or otherwise harmful. In its prepared forms, in which its toxic or unpleasant components have been reduced to acceptable levels, it contains an extremely high proportion of starch. These are decomposed by linamarase, a naturally occurring enzyme in cassava, liberating hydrogen cyanide (HCN). Cooked cassava starch has a digestibility of over 75%.[33]. The starch grains that flow with the water during the soaking process are also used in cooking. In Nigeria and several other west African countries, including Ghana, Cameroon, Benin, Togo, Ivory Coast, and Burkina Faso, they are usually grated and lightly fried in palm oil to preserve them. Drying may not be sufficient, either. Csec History: The Tainos vs. the Kalinagos, History unfolding with the comparison of the Tainos and Kalinagos. These starches have similarities and differences depending upon their chemical makeup and nutrient content. [59], While alternative methods for PPD control have been proposed, such as preventing ROS effects by use of plastic bags during storage and transport, coating the roots with wax, or freezing roots, such strategies have proved to be economically or technically impractical, leading to breeding of cassava varieties more tolerant to PPD and with improved durability after harvest. The so-called sweet (actually not bitter) cultivars can produce as little as 20 milligrams of cyanide (CN) per kilogram of fresh roots, whereas bitter ones may produce more than 50 times as much (1 g/kg). This mutated virus spread at a rate of 80 kilometres (50 miles) per year, and as of 2005 was found throughout Uganda, Rwanda, Burundi, the Democratic Republic of the Congo and the Republic of the Congo. [6], For some smaller-rooted, sweet varieties, cooking is sufficient to eliminate all toxicity. In 2018, global production of cassava root was 278 million tonnes, with Nigeria as the world's largest producer, having 21% of the world total (table). [citation needed] It can be made into a flour that is used in breads, cakes and cookies. [13] The oldest direct evidence of cassava cultivation comes from a 1,400-year-old Maya site, Joya de Cerén, in El Salvador. [57], Spreading Casabe burrero (cassava bread) to dry, Venezuela, Cassava starch being prepared for packaging, Cassava starch packaged and ready for shipping, Frozen cassava leaves in a Los Angeles market, Cassava undergoes post-harvest physiological deterioration (PPD) once the tubers are separated from the main plant. [3][4] Cassava is a major staple food in the developing world, providing a basic diet for over half a billion people. Online converters for all flour types. [7][6] Farmers often prefer the bitter varieties because they deter pests, animals, and thieves. Alcoholic beverages made from cassava include cauim and tiquira[what language is this?] [28], Cassava, yams (Dioscorea spp. Raw cassava is 60% water, 38% carbohydrates, 1% protein, and has negligible fat (table). Fresh cassava can be preserved like potato, using thiabendazole or bleach as a fungicide, then wrapping in plastic, coating in wax or freezing. Selection of cassava species to be grown, therefore, is quite important. Flour is a powder made by grinding raw grains, roots, beans, nuts, or seeds.Flours are used to make many different foods. Sweet potato and cassava can modify cholesterol profile in humans with moderately raised serum cholesterol levels. While it is a valued food staple in parts of eastern Indonesia, it is primarily cultivated for starch extraction and bio-fuel production in Thailand, Cambodia or Vietnam. Maize and cassava are now important staple foods, replacing native African crops in places such as Tanzania. [6], "Chronic, low-level cyanide exposure is associated with the development of goiter and with tropical ataxic neuropathy, a nerve-damaging disorder that renders a person unsteady and uncoordinated. Worldwide, 800 million people depend on cassava as their primary food staple. [49] The flour is used throughout South America and the Caribbean. The purple sweet potato goes by a few names, and there are two common varieties. These include Pratylenchus brachyurus, Rotylenchulus reniformis, Helicotylenchus spp., Scutellonema spp. It is also referred to as tapioca in Indian English usage. The upper parts of the stems with the leaves are plucked off before harvest. In Brazil, detoxified manioc is ground and cooked to a dry, often hard or crunchy meal known as farofa used as a condiment, toasted in butter, or eaten alone as a side dish. [19] Sailors complained that it caused them digestive problems. This description definitely holds in Africa and parts of South America; in Asian countries such as Vietnam fresh cassava barely features in human diets.[24]. In Assam it is an important source of carbohydrates especially for natives of hilly areas. [39] Cassava varieties are often categorized as either sweet or bitter, signifying the absence or presence of toxic levels of cyanogenic glucosides, respectively. The Spanish also needed to replenish their boats with dried meat, water, fruit, and large amounts of cassava bread. What did the Tainos  eat as opposed to a the Kalinagos. [69][75], "Yuca" redirects here. [62] A wide range of species that feed directly on dried cassava chips have been reported as a major factor in spoiling stored cassava, with losses between 19% and 30% of the harvested produce. Fermentation is also used in other places such as Indonesia (see Tapai). and Meloidogyne spp., of which Meloidogyne incognita and Meloidogyne javanica are the most widely reported and economically important. It continues until the entire tuber is oxidized and blackened within two to three days after harvest, rendering it unpalatable and useless. Cassava, like other foods, also has antinutritional and toxic factors. feeding produces physically damaging galls with eggs inside them. "[45][46], During the shortages in Venezuela in the late 2010s, dozens of deaths were reported due to Venezuelans resorting to eating bitter cassava in order to curb starvation. Compared to most staples; however, cassava is a poorer dietary source of protein and most other essential nutrients. Aside from matzo prepared under strict guidelines, forbidden Passover ingredients include wheat, barley, rye, oats and spelt. [71][72][68][73] Since nematodes have such a seemingly erratic distribution in cassava agricultural fields, it is not easy to clearly define the level of direct damage attributed to nematodes and thereafter quantify the success of a chosen management method. In many countries, significant research has begun to evaluate the use of cassava as an ethanol biofuel feedstock. Cassava growth is favorable under temperatures ranging from 25 to 29 °C (77 to 84 °F), but it can tolerate temperatures as low as 12 °C (54 °F) and as high as 40 °C (104 °F). These pests can cause up to 80 percent crop loss, which is extremely detrimental to the production of subsistence farmers. It is valued as a good roughage source for ruminants such as cattle.[38]. [10] However, they are poor in protein and other nutrients. [14] With its high food potential, it had become a staple food of the native populations of northern South America, southern Mesoamerica, and the Taino people in the Caribbean islands, who grew it using a high-yielding form of shifting agriculture by the time of European contact in 1492. 60 percent of cassava, like other foods, replacing native African crops feeding...
