Nixtamalization
Nixtamalization ( ) is a process for the preparation of maize (corn), or other cereal grain, grain, in which the grain is soaked and cooking, cooked in an alkaline solution, usually limewater (but sometimes aqueous alkali metal carbonates), washed, and then hulling, 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 (taste), flavor and aroma are improved, and mycotoxins are reduced by up to 97–100% (for aflatoxin, 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. The tryptophan in corn proteins is made more available for human absorption, thus helping to prevent niacin deficiency (pellagra). Tryptophan is the ...

Maize
Maize (; ''Zea mays''), also known as corn in North American English, is a tall stout grass that produces cereal grain. It was domesticated by indigenous peoples in southern Mexico about 9,000 years ago from wild teosinte. Native Americans planted it alongside beans and squashes in the Three Sisters polyculture. The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ears. The ears yield grain, known as kernels or seeds. In modern commercial varieties, these are usually yellow or white; other varieties can be of many colors. Maize relies on humans for its propagation. Since the Columbian exchange, it has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat and rice. Much maize is used for animal feed, whether as grain or as the whole plant, which can either be baled or made into the more palatable silage. Sugar-rich varieties called sw ...

Pellagra
Pellagra is a disease caused by a lack of the vitamin niacin (vitamin B3). Symptoms include inflamed skin, diarrhea, dementia, and sores in the mouth. Areas of the skin exposed to friction and radiation are typically affected first. Over time affected skin may become darker, stiffen, peel, or bleed. There are two main types of pellagra, primary and secondary. Primary pellagra is due to a diet that does not contain enough niacin and tryptophan. Secondary pellagra is due to a poor ability to use the niacin within the diet. This can occur as a result of alcoholism, long-term diarrhea, carcinoid syndrome, Hartnup disease, and a number of medications such as isoniazid. Diagnosis is typically based on symptoms and may be assisted by urine testing. Treatment is with either nicotinic acid or nicotinamide supplementation. Improvements typically begin within a couple of days. General improvements in diet are also frequently recommended. Decreasing sun exposure via sunscreen and ...

Hominy (maize)
Hominy is a food item 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 sourdough. The process of nixtamalization spread from M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limewater
Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca( OH)2. It is a colorless crystal or white powder and is produced when quicklime ( calcium oxide) is mixed with water. Annually, approximately 125 million tons of calcium hydroxide are produced worldwide. Calcium hydroxide has many names including hydrated lime, caustic lime, builders' lime, slaked lime, cal, and pickling lime. Calcium hydroxide is used in many applications, including food preparation, where it has been identified as E number E526. Limewater, also called milk of lime, is the common name for a saturated solution of calcium hydroxide. Solubility Calcium hydroxide is moderately soluble in water, as seen for many dihydroxides. Its solubility increases from 0.66 g/L at 100 °C to 1.89 g/L at 0 °C. Its solubility product ''K''sp of 5.02 at 25 °C, its dissociation in water is large enough that its solutions are basic according to the followin ...

Masa
''Masa'' or ''masa de maíz'' (; ) is a dough made from ground nixtamalized maize. It is used for making corn tortillas, '' gorditas'', '' tamales'', '' pupusas'', and many other Latin American dishes. It is dried and powdered into a flour form called ''harina de maíz'' or ''masa harina''. Masa is reconstituted by mixing with water before using it in cooking. In Spanish, ''masa harina'' translates simply to 'dough flour', and 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 directly, or can be dehydrated and blended into a powder to create m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tortilla Chip
A tortilla chip is a snack food made from corn tortilla, 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 Nixtamalization , 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 tostada (tortilla), tostadas. Though usually made of yellow corn, they can also be made of white, blue corn, 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. Tortilla chips may be served as a garnish (food), garnish for soups or dishes such as chili con carne. History Ignacio Anaya used triangles of fried tortilla for the nachos he created in 1943. The triangle-shaped tortilla chip was popularized by Rebecca Webb Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornmeal
Maize meal is a meal (coarse flour) ground from dried maize. It is a common staple food and is ground to coarse, medium, and fine consistencies, but it is 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 and Louisiana, 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-gro ... [...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, very crunchy, have the strong aroma and flavor of roasted corn, and are often heavily seasoned with salt. Overview 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 mixes. 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. See ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mycotoxin
A mycotoxin (from the Greek μύκης , "fungus" and τοξικός , "poisonous") is a toxic secondary metabolite produced by fungi and is capable of causing disease and death in both humans and other animals. The term 'mycotoxin' is usually reserved for the toxic chemical products produced by fungi that readily colonize crops. Examples of mycotoxins causing human and animal illness include aflatoxin, citrinin, fumonisins, ochratoxin A, patulin, trichothecenes, zearalenone, and ergot alkaloids such as ergotamine. One mold species may produce many different mycotoxins, and several species may produce the same mycotoxin. Production Most fungi are aerobic (use oxygen) and are found almost everywhere in extremely small quantities due to the diminutive size of their spores. They consume organic matter wherever humidity and temperature are sufficient. Where conditions are right, fungi proliferate into colonies and mycotoxin levels become high. The reason for the production of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tamale
A tamale, in Spanish language, Spanish , is a traditional Mesoamerican dish made of ''masa'', a dough made from nixtamalization, nixtamalized maize, corn, which is steaming, steamed in a corn husk or Banana leaf, banana leaves. The wrapping can either be discarded prior to eating or used as a plate. Tamales can be filled with meats, cheeses, fruits, vegetables, herbs, chili pepper, chilies, or any preparation according to taste, and both the filling and the cooking liquid may be seasoned. ''Tamale'' is an Anglicisation, anglicized version of the Spanish word (plural: ). comes from the Nahuatl . The English "tamale" is a back-formation from , with English speakers applying English pluralization rules, and thus interpreting the ''-e-'' as part of the Word stem, 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 Mesoa ...

Niacin
Nicotinic acid, or niacin, is an organic compound and a vitamer of vitamin B3, an essential human nutrient. It is produced by plants and animals from the amino acid tryptophan. Nicotinic acid is also a prescription medication. Amounts far in excess of the recommended dietary intake for vitamin functions will lower blood triglycerides and low density lipoprotein cholesterol (LDL-C), and raise blood high density lipoprotein cholesterol (HDL-C, often referred to as "good" cholesterol). There are two forms: immediate-release and sustained-release nicotinic acid. Initial prescription amounts are 500 mg/day, increased over time until a therapeutic effect is achieved. Immediate-release doses can be as high as 3,000 mg/day; sustained-release as high as 2,000 mg/day. Despite the proven lipid changes, nicotinic acid has not been found useful for decreasing the risk of cardiovascular disease in those already prescribed a statin drug. A 2010 review had concluded that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
