Nixtamalization
Nixtamalization () is a process for the preparation of corn, or other grain, in which the grain is soaked and cooked in an alkaline solution, usually limewater (but sometimes aqueous alkali metal carbonates), washed, and then hulled. The term can also refer to the removal via an alkali process of the pericarp from other grains such as sorghum. Nixtamalized corn has several benefits over unprocessed grain: It is more easily ground, its nutritional value is increased, flavor and aroma are improved, and mycotoxins are reduced by up to 97%–100% (for aflatoxins). Lime and ash are highly alkaline: the alkalinity helps the dissolution of hemicellulose, the major glue-like component of the maize cell walls, and loosens the hulls from the kernels and softens the maize. Corn's hemicellulose-bound niacin is converted to free niacin (a form of vitamin B3), making it available for absorption into the body, thus helping to prevent pellagra. Some of the corn oil is broken down into emu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limewater
Limewater is the common name for a saturated aqueous solution of calcium hydroxide. Calcium hydroxide, Ca(OH)2, is sparsely soluble at room temperature in water (1.5 g/L at 25 °C). "Pure" (i.e. less than or fully saturated) limewater is clear and colorless, with a slight earthy smell and an astringent/bitter taste. It is basic in nature with a pH of 12.4. Limewater may be prepared by mixing calcium hydroxide (Ca(OH)2) with water and removing excess undissolved solute (e.g. by filtration). When excess calcium hydroxide is added (or when environmental conditions are altered, e.g. when its temperature is raised sufficiently), a milky solution results due to the homogeneous suspension of excess calcium hydroxide. This liquid has been known traditionally as milk of lime. Chemistry An experiment commonly used to demonstrate the interaction of CO2 and Ca(OH)2 is as follows. Resultant carbon dioxide passed through limewater in the right tube, producing a milky solution due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemicellulose
A hemicellulose (also known as polyose) is one of a number of heteropolymer, heteropolymers (matrix polysaccharides), such as arabinoxylans, present along with cellulose in almost all embryophyte, terrestrial plant cell walls.Scheller HV, Ulvskov Hemicelluloses.// Annu Rev Plant Biol. 2010;61:263-89. doi: 10.1146/annurev-arplant-042809-112315. Cellulose is crystalline, strong, and resistant to hydrolysis. Hemicelluloses are branched, shorter in length than cellulose, and also show a propensity to crystallize. They can be hydrolyzed by dilute acid or Base (chemistry), base as well as a myriad of Cellulase, hemicellulase enzymes. Composition Diverse kinds of hemicelluloses are known. Important examples include xylan, glucuronoxylan, arabinoxylan, glucomannan, and xyloglucan. Hemicelluloses are polysaccharides often associated with cellulose, but with distinct compositions and structures. Whereas cellulose is derived exclusively from glucose, hemicelluloses are composed of diverse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nahuatl
Nahuatl (; ), Aztec, or Mexicano is a language or, by some definitions, a group of languages of the Uto-Aztecan language family. Varieties of Nahuatl are spoken by about Nahua peoples, most of whom live mainly in Central Mexico and have smaller populations in the United States. Nahuatl has been spoken in central Mexico since at least the seventh century CE. It was the language of the Aztec/ Mexica, who dominated what is now central Mexico during the Late Postclassic period of Mesoamerican history. During the centuries preceding the Spanish and Tlaxcalan conquest of the Aztec Empire, the Aztecs had expanded to incorporate a large part of central Mexico. Their influence caused the variety of Nahuatl spoken by the residents of Tenochtitlan to become a prestige language in Mesoamerica. After the conquest, when Spanish colonists and missionaries introduced the Latin alphabet, Nahuatl also became a literary language. Many chronicles, grammars, works of poetry, administrative docu ...

Aztec
The Aztecs () were a Mesoamerican culture that flourished in central Mexico in the post-classic period from 1300 to 1521. The Aztec people included different Indigenous peoples of Mexico, ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl, Nahuatl language and who dominated large parts of Mesoamerica from the 14th to the 16th centuries. Aztec culture was organized into city-states (''altepetl''), some of which joined to form alliances, political confederations, or empires. The Aztec Empire was a confederation of three city-states established in 1427: Tenochtitlan, city-state of the Mexica or Tenochca; Texcoco (altepetl), Texcoco; and Tlacopan, previously part of the Tepanec empire, whose dominant power was Azcapotzalco (altepetl), Azcapotzalco. Although the term Aztecs is often narrowly restricted to the Mexica of Tenochtitlan, it is also broadly used to refer to Nahuas, Nahua polities or peoples of central Pre-Columbian Mexico, Mexico in the preh ...

Hominy
Hominy (Spanish: maíz molido; literally meaning "milled corn") is a food produced from dried maize (corn) kernels that have been treated with an alkali, in a process called nixtamalization ( is the Nahuatl word for "hominy"). "Lye hominy" is a type of hominy made with lye. History The process of nixtamalization has been fundamental to Mesoamerican cuisine since ancient times. The lime used to treat the maize can be obtained from several different materials. Among the Lacandon Maya who inhabited the tropical lowland regions of eastern Chiapas, the caustic powder was obtained by toasting freshwater shells over a fire for several hours. In the highland areas of Chiapas and throughout much of the Yucatán Peninsula, Belize River valley and Petén Basin, limestone was used to make slaked lime for steeping the shelled kernels. The Maya used nixtamal to produce beers that more resembled '' chicha'' than ''pulque''. When bacteria were introduced to nixtamal it created a type of ...

Tamale
A tamale, in Spanish tamal, is a traditional Mesoamerican dish made of masa, a dough made from nixtamalized corn, which is steamed in a corn husk or banana leaf. The wrapping can either be discarded prior to eating or used as a plate. Tamales can be filled with meats, cheeses, fruits, vegetables, herbs, chilies, or any preparation according to taste, and both the filling and the cooking liquid may be seasoned. ''Tamale'' is an anglicized version of the Spanish word (plural: ). comes from the Nahuatl . The English "tamale" is a back-formation of , with English speakers interpreting the ''-e-'' as part of the stem, rather than part of the plural suffix ''-es''. Origin Tamales originated in Mesoamerica as early as 8000 to 5000 BC. The preparation of tamales is likely to have spread from the indigenous cultures in Guatemala and Mexico to the rest of Latin America. According to archaeologists Karl Taube, William Saturno, and David Stuart, tamales may date from around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Corn Chip
Corn chips are a snack food made from cornmeal fried in oil or baked, usually in the shape of a small noodle or scoop. Corn chips are thick, rigid and very crunchy. Corn chips have the strong aroma and flavor of roasted corn, and are often heavily seasoned with salt. In the United States, Fritos is one of the oldest and most widely recognized brands of corn chips. While corn chips and tortilla chips are both made from corn, the corn in tortilla chips is subjected to the nixtamalization process, resulting in a milder flavor and aroma, and a less rigid texture. Tortilla chips also tend to be larger, thinner, less fatty, and less salty than corn chips. Corn chips are usually eaten alone or with a chip dip. They are a common ingredient in homemade and commercial party mix. In the Southwestern US, a popular dish, Frito pie, is made with corn chips and chili. In some areas, it is popular to pour the chili into a bag of corn chips and eat the mixture directly from the bag. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortilla Chip
A tortilla chip is a snack food made from corn tortillas, which are cut into triangles and then fried or baked (alternatively they may be discs pressed out of corn masa then fried or baked). Corn tortillas are made of nixtamalized corn, vegetable oil, salt and water. Although first mass-produced commercially in the U.S. in Los Angeles in the late 1940s, tortilla chips grew out of Mexican cuisine, where similar items were well known, such as totopos and tostadas. Though usually made of yellow corn, they can also be made of white, blue, or red corn. Tortilla chips intended to be dipped are typically only lightly salted, while others may be seasoned with a variety of flavors. History The triangle-shaped tortilla chip was popularized by Rebecca Webb Carranza in the 1940s as a way to make use of misshapen tortillas rejected from the automated tortilla manufacturing machine that she and her husband used at their Mexican delicatessen and tortilla factory in southwest Los Angeles.

Tortilla
A tortilla (, ) is a thin, circular unleavened flatbread originally made from maize hominy meal, and now also from wheat flour. The Aztecs and other Nahuatl speakers called tortillas ''tlaxcalli'' (). First made by the indigenous peoples of Mesoamerica before colonization, tortillas are a cornerstone of Mesoamerican cuisine. Corn tortillas in Mesoamerica are known from as early as 500 BCE. Varieties Corn tortilla Tortillas made from nixtamalized maize meal—masa de maíz— are the oldest variety of tortilla. They originated in Mexico and Central America, and remain popular throughout the Americas. Peoples of the Oaxaca region in Mexico first made tortillas at the end of the Villa Stage (1500 to 500 BC). Towards the end of the 19th century, the first mechanical utensils for making tortillas, called tortilla presses, tortilleras, or tortilladoras, were invented and manufactured in Mexico. Wheat tortilla Europeans introduced wheat and its cultivation to the America ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Masa
''Masa'' (or ''masa de maíz'') (; ) is a maize dough that comes from ground nixtamalization, nixtamalized corn. It is used for making corn tortillas, ''gorditas'', ''tamales'', ''pupusas'', and many other Latin American cuisine, Latin American dishes. It is dried and powdered into a maize flour, flour form called ''masa harina''. Masa is reconstituted from masa harina by mixing with water before use in cooking. In Spanish language, Spanish, ''masa harina'' translates to "dough flour", which can refer to many other types of dough. Preparation Field corn grain is dried and then treated by cooking the mature, hard grain in a diluted solution of slaked lime (calcium hydroxide) or wood ash, and then letting it soak for many hours. The soaked maize is then rinsed thoroughly to remove the unpalatable flavor of the alkali. This process is nixtamalization, and it produces hominy, which is ground into a relatively dry dough to create fresh masa. The fresh masa can be sold or used directl ...

Cornmeal
Cornmeal is a meal (coarse flour) or a cell membrane ground from dried corn. It is a common staple food, and is ground to coarse, medium, and fine consistencies, but not as fine as wheat flour can be.Herbst, Sharon, ''Food Lover's Companion'', Third Edition, Pg. 165, Barrons Educational Series Inc, 2001 In Mexico, very finely ground cornmeal is referred to as corn flour. When fine cornmeal is made from maize that has been soaked in an alkaline solution, e.g., limewater (a process known as nixtamalization), it is called masa harina (or masa flour), which is used for making arepas, tamales and tortillas. Boiled cornmeal is called polenta in Italy and is also a traditional dish and bread substitute in Romania. Types There are various types of cornmeal: *''Blue cornmeal'' is light blue or violet in color. It is ground from whole blue corn and has a sweet flavor. The cornmeal consists of dried corn kernels that have been ground into a fine or medium texture. *''Steel-ground yellow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
