Lye
A lye is a metal hydroxide traditionally obtained by leaching wood ashes, or a strong alkali which is highly soluble in water producing caustic basic solutions. "Lye" most commonly refers to sodium hydroxide (NaOH), but historically has been used for potassium hydroxide (KOH). Today, lye is commercially manufactured using a membrane cell chloralkali process. It is supplied in various forms such as flakes, pellets, microbeads, coarse powder or a solution. Lye has traditionally been used as a major ingredient in soapmaking. Etymology The English word has cognates in all Germanic languages, and originally designated a bath or hot spring. Uses Food Lyes are used to cure many types of food, including the traditional Nordic lutefisk, olives (making them less bitter), canned mandarin oranges, hominy, lye rolls, century eggs, pretzels, and bagels. They are also used as a tenderizer in the crust of baked Cantonese moon cakes, in "zongzi" (glutinous rice dumplings wrapped in ba ...

Sodium Hydroxide
Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations and hydroxide anions . Sodium hydroxide is a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures and may cause severe chemical burns. It is highly soluble in water, and readily absorbs moisture and carbon dioxide from the air. It forms a series of hydrates . The monohydrate crystallizes from water solutions between 12.3 and 61.8 °C. The commercially available "sodium hydroxide" is often this monohydrate, and published data may refer to it instead of the anhydrous compound. As one of the simplest hydroxides, sodium hydroxide is frequently used alongside neutral water and acidic hydrochloric acid to demonstrate the pH scale to chemistry students. Sodium hydroxide is used in many industries: in the manufacture of pulp and paper, textiles, drinking water, soap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lye Roll
Lye rolls are a baked specialty in Germany (especially in Bavaria and Swabia), France (Alsace), Austria, and Switzerland. They are made by immersing bread rolls in a lye solution before baking. The German name is ''Laugengebäck'' for any baked good dipped in lye. The perhaps best known shape is the pretzel, while rolls or buns are specifically called ''Laugensemmel'' or ''Kastanie'' (Bavarian), ''Laugeweckle'' or ''Laugestängle'' (Swabian), and ''Laugenwecken'', ''Laugenbrötchen'' or ''Laugenstange'' (everywhere else in Germany); ''Laugenweckerl'' in Austria; ''Silserli'' or ''Laugenbrötli'' in Switzerland. In some parts of Asia they are known as ''laugen rolls''. In France, the lye roll is known as mauricette and was invented by Paul Poulaillon in Alsace region when he opened the first Poulaillon bakery in 1973. It was later registered as a trademark with an alternate name Moricette in 1985 and the lard was replaced by canola oil. Lye In order to cause a Maillard reacti ...

Pretzel
A pretzel (), from German pronunciation, standard german: Breze(l) ( and French / Alsatian: ''Bretzel'') is a type of baked bread made from dough that is commonly shaped into a knot. The traditional pretzel shape is a distinctive symmetrical form, with the ends of a long strip of dough intertwined and then twisted back onto itself in a particular way (a pretzel loop or pretzel bow). Today, pretzels come in a wide range of shapes. Salt is the most common seasoning, or topping, for pretzels, complementing the washing soda or lye treatment that gives pretzels their traditional skin and flavor acquired through the Maillard reaction. Other seasonings are mustard, cheeses, sugar, chocolate, cinnamon, sweet glazing, seeds, and nuts. Varieties of pretzels include soft pretzels, which should be eaten shortly after preparation, and hard-baked pretzels, which have a long shelf life. History There are numerous accounts regarding the origin of pretzels, as well as the origin of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olive
The olive, botanical name ''Olea europaea'', meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as ''Olea europaea'' 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. ''Olea europaea'' is the type species for the genus '' Olea''. The olive's fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil; it is one of the core ingredients in Mediterranean cuisine. The tree and its fruit give their name to the plant family, which also includes species such as lilac, jasmine, forsythia, and the true ash tree. Thousands of cultivars of the olive tree are known. Olive cultivars may be used primarily for oil, eating, or both. Olives cultivated for consumption are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Noodles
Chinese noodles vary widely according to the region of production, ingredients, shape or width, and manner of preparation. Noodles were invented in China, and are an essential ingredient and staple in Chinese cuisine. They are an important part of most regional cuisines within China, and other countries with sizable overseas Chinese populations. Chinese noodles can be made of wheat, buckwheat, rice, millet, oats, beans, potatoes, sweet potatoes, and even fish. There are over 1,200 types of noodles commonly consumed in China today. Chinese noodles have also entered the cuisines of neighboring East Asian countries such as Korea and Japan, as well as Southeast Asian countries such as Vietnam, Cambodia, and Thailand. Nomenclature Nomenclature of Chinese noodles can be difficult due to the vast spectrum available in China and the many dialects of Chinese used to name them. In Mandarin, miàn (; often transliterated as "mien" or "mein" ) refers to noodles made from wheat flour, whil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutefisk
''Lutefisk'' ( Norwegian, in Northern and parts of Central Norway, in Southern Norway; sv, lutfisk ; fi, lipeäkala ; literally " lye fish") is dried whitefish (normally cod, but ling and burbot are also used). It is made from aged stockfish (air-dried whitefish), or dried and salted cod, cured in lye. It is gelatinous in texture after being rehydrated for days prior to eating. Lutefisk is prepared as a seafood dish of several Nordic countries. It is traditionally part of the Christmas feast; Norwegian julebord and Swedish julbord, as well as the similar Finnish joulupöytä. Origin Preserved fish provided protein for generations in a part of the world with a strong fishing tradition. It is not known when people first started treating dried fish with lye. The reason was probably that the lack of major salt deposits in the area favored the drying process for the preservation of whitefish - a process known for millennia. Stockfish is very nutrient-rich and wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 typ ...

Pitsi-pitsî
Pichi-pichi, also spelled pitsi-pitsi, is a Filipino dessert made from steamed cassava flour balls mixed with sugar and lye. It is also commonly flavored with pandan leaves. It is served rolled in freshly grated coconut, cheese, or latik (coconut caramel) before serving. A similar dish to pichi-pichi is the putli mandi of the Tausug and Yakan people. It is prepared identically, and differs only in that it has a filling of sweetened coconut strips ('' hinti''). It is also similar to palitaw, except palitaw is made into thin flat cakes and is made with glutinous rice flour. Preparation The cassava is first peeled, grated, and washed. The grated cassava is then mixed with water, sugar, and lye and then the mixture is transferred into pans or molds which are then put in the steamer until the mixture is cooked and soft. The cooked pitsi-pitsi can then be rolled on freshly grated coconut or topped with grated cheese and latik. Some vendors add food coloring to the mixture prior to ...

Kutsinta
''Puto cuchinta'' or ''kutsinta'' is a type of Steaming, steamed rice cake (''Puto (food), puto'') found throughout the Philippines. It is made from a mixture of tapioca or rice flour, brown sugar and lye, enhanced with yellow food coloring or Annatto#Food coloring, annatto extract, and steamed in small ramekins. It bears resemblance to the Burmese ''mont kywe the'' and Indonesian and Malaysian ''kuih kosui''. The cooked cakes are topped with fresh grated meat from mature coconut. It is consumed year-round as a ''merienda'' or snack, and is frequently sold along with ''Puto (food), puto''. Unlike its counterpart, which has a doughy texture, ''kutsina'' has a jelly-like, chewy consistency. It can be also enhanced by adding ''latik'' for a sweeter taste. Preparation Add the lye water to the melted brown sugar. Then, mix it with the glutinous rice flour and rice flour until dissolved thoroughly. Strain after to remove lumps; you may add a red liquid food color. Brush the mold with v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glutinous Rice
Glutinous rice ('' Oryza sativa var. glutinosa''; also called sticky rice, sweet rice or waxy rice) is a type of rice grown mainly in Southeast and East Asia, and the northeastern regions of South Asia, which has opaque grains, very low amylose content, and is especially sticky when cooked. It is widely consumed across Asia. It is called glutinous ( la, glūtinōsus) in the sense of being glue-like or sticky, and not in the sense of containing gluten (which it does not). While often called ''sticky rice'', it differs from non-glutinous strains of japonica rice which also become sticky to some degree when cooked. There are numerous cultivars of glutinous rice, which include ''japonica'', ''indica'' and ''tropical japonica'' strains. History In China, glutinous rice has been grown for at least 2,000 years. However, researchers believe that glutinous rice distribution appears to have been culturally influenced and closely associated with the early southward migration and dis ...

Membrane (selective Barrier)
A membrane is a selective barrier; it allows some things to pass through but stops others. Such things may be molecules, ions, or other small particles. Membranes can be generally classified into synthetic membranes and biological membranes. Biological membranes include cell membranes (outer coverings of cells or organelles that allow passage of certain constituents); nuclear membranes, which cover a cell nucleus; and tissue membranes, such as mucosae and serosae. Synthetic membranes are made by humans for use in laboratories and industry (such as chemical plants). This concept of a membrane has been known since the eighteenth century but was used little outside of the laboratory until the end of World War II. Drinking water supplies in Europe had been compromised by the war and membrane filters were used to test for water safety. However, due to the lack of reliability, slow operation, reduced selectivity and elevated costs, membranes were not widely exploited. The first ...

Potassium Hydroxide
Potassium hydroxide is an inorganic compound with the formula K OH, and is commonly called caustic potash. Along with sodium hydroxide (NaOH), KOH is a prototypical strong base. It has many industrial and niche applications, most of which exploit its caustic nature and its reactivity toward acids. An estimated 700,000 to 800,000 tonnes were produced in 2005. KOH is noteworthy as the precursor to most soft and liquid soaps, as well as numerous potassium-containing chemicals. It is a white solid that is dangerously corrosive. Properties and structure KOH exhibits high thermal stability. Because of this high stability and relatively low melting point, it is often melt-cast as pellets or rods, forms that have low surface area and convenient handling properties. These pellets become tacky in air because KOH is hygroscopic. Most commercial samples are ca. 90% pure, the remainder being water and carbonates. Its dissolution in water is strongly exothermic. Concentrated aqueous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
