Onggi
''Onggi'' () is Korean earthenware extensively used as tableware and storage containers in Korea. It includes both Ceramic glaze, unglazed earthenware, fired near 600 to 700°C, and pottery with a dark brown Ceramic glaze, glaze fired at over 1100 °C.The origin of onggi dates to around 4000 to 5000 BCE. The types of earthenware include patternless, Mumun pottery period, ''mumun'', and a red and black variety. The patternless earthenware is made with lumps of clay and fine sand. The predecessor of Goryeo celadon and Joseon white porcelain, the black/red earthenware excludes any sand in its creation process. The earthenware's color is determined by both the iron content of the clay and the method used to fire it. The modern onggi shape dates back from the Joseon era. Many records about onggi are found in ''Sejong Sillok Jiriji'' (, "King Sejong's Treatise on Geography"), which includes further details about Korean pottery: "There are three kilns that make the yellow onggi in Ch ...

Soy Sauce
Soy sauce (also called simply soy in American English and soya sauce in British English) is a liquid condiment of Chinese origin, traditionally made from a fermented paste of soybeans, roasted grain, brine, and '' Aspergillus oryzae'' or ''Aspergillus sojae'' molds. It is considered to contain a strong umami taste. Soy sauce in its current form was created about 2,200 years ago during the Western Han dynasty of ancient China, and it has spread throughout East and Southeast Asia where it is used in cooking and as a condiment. Use and storage Soy sauce can be added directly to food, and is used as a dip or salt flavor in cooking. It is often eaten with rice, noodles, and sushi or sashimi, or can also be mixed with ground wasabi for dipping. Bottles of soy sauce for salty seasoning of various foods are common on restaurant tables in many countries. Soy sauce can be stored at room temperature.

Kimchi
''Kimchi'' (; ko, 김치, gimchi, ), is a traditional Korean side dish of salted and fermented vegetables, such as napa cabbage and Korean radish. A wide selection of seasonings are used, including ''gochugaru'' (Korean chili powder), spring onions, garlic, ginger, and ''jeotgal'' (salted seafood), etc. Kimchi is also used in a variety of soups and stews. As a staple food in Korean cuisine, it is eaten as a side dish with almost every Korean meal. There are hundreds of different types of kimchi made with different vegetables as the main ingredients. Traditionally, winter kimchi, called kimjang, was stored in large earthenware fermentation vessels, called ''onggi'', in the ground to prevent freezing during the winter months and to keep it cool enough to slow down the fermentation process during summer months. The vessels are also kept outdoors in special terraces called jangdokdae. In contemporary times, household kimchi refrigerators are more commonly used. Etymology ...

Doenjang
''Doenjang'' * (; "thick sauce") or soybean paste is a type of fermented bean paste made entirely of soybean and brine. It is also a byproduct of soup soy sauce production. It is sometimes used as a relish. History The earliest soybean fermentations in Korea seem to have begun prior to the era of the Three Kingdoms. The '' Records of the Three Kingdoms'', a Chinese historical text written and published in the third century AD, mentions that "Goguryeo people are good at brewing fermented soybeans" in the section named ''Dongyi'' (Eastern foreigners), in the '' Book of Wei''. Jangdoks used for doenjang production are found in the mural paintings of Anak Tomb No.3 from the 4th century Goguryeo. In ''Samguk Sagi'', a historical record of the Three Kingdoms era, it is written that ''doenjang'' and ''ganjang'' along with ''meju'' and ''jeotgal'' were prepared for the wedding ceremony of the King Sinmun in February 683.

Korea
Korea ( ko, 한국, or , ) is a peninsular region in East Asia. Since 1945, it has been divided at or near the 38th parallel, with North Korea (Democratic People's Republic of Korea) comprising its northern half and South Korea (Republic of Korea) comprising its southern half. Korea consists of the Korean Peninsula, Jeju Island, and several minor islands near the peninsula. The peninsula is bordered by China to the northwest and Russia to the northeast. It is separated from Japan to the east by the Korea Strait and the Sea of Japan (East Sea). During the first half of the 1st millennium, Korea was divided between three states, Goguryeo, Baekje, and Silla, together known as the Three Kingdoms of Korea. In the second half of the 1st millennium, Silla defeated and conquered Baekje and Goguryeo, leading to the "Unified Silla" period. Meanwhile, Balhae formed in the north, superseding former Goguryeo. Unified Silla eventually collapsed into three separate states due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goguryeo
Goguryeo (37 BC–668 AD) ( ) also called Goryeo (), was a Korean kingdom located in the northern and central parts of the Korean Peninsula and the southern and central parts of Northeast China. At its peak of power, Goguryeo controlled most of the Korean peninsula, large parts of Manchuria and parts of eastern Mongolia and Inner Mongolia. Along with Baekje and Silla, Goguryeo was one of the Three Kingdoms of Korea. It was an active participant in the power struggle for control of the Korean peninsula and was also associated with the foreign affairs of neighboring polities in China and Japan. The ''Samguk sagi'', a 12th-century text from Goryeo, indicates that Goguryeo was founded in 37 BC by Jumong (), a prince from Buyeo, who was enthroned as Dongmyeong. Goguryeo was one of the great powers in East Asia, until its defeat by a Silla–Tang alliance in 668 after prolonged exhaustion and internal strife caused by the death of Yeon Gaesomun (). After its fall, its territory w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porosity
Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from the surface (cf. closed-cell foam). There are many ways to test porosity in a substance or part, such as industrial CT scanning. The term porosity is used in multiple fields including pharmaceutics, ceramics, metallurgy, materials, manufacturing, petrophysics, hydrology, earth sciences, soil mechanics, and engineering. Void fraction in two-phase flow In gas-liquid two-phase flow, the void fraction is defined as the fraction of the flow-channel volume that is occupied by the gas phase or, alternatively, as the fraction of the cross-sectional area of the channel that is occupied by the gas phase. Void fraction usually varies from location to location in the flow ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fermented Bean Paste
Fermented bean paste is a category of fermented foods typically made from ground soybeans, which are indigenous to the cuisines of East, South and Southeast Asia. In some cases, such as the production of ''miso'', other varieties of beans, such as broad beans, may also be used. The pastes are usually salty and savoury, but may also be spicy, and are used as a condiment to flavour foods such as stir-fries, stews, and soups. The colours of such pastes range from light tan to reddish brown and dark brown. The differences in colour are due to different production methods, such as the conditions of fermentation, the addition of wheat flour, pulverized mantou, rice, or sugar and the presence of different microflora, such as bacteria or molds used in their production, as well as whether the soybeans are roasted (as in ''chunjang'') or aged (as in ''tauco'') before being ground. Fermented bean pastes are sometimes the starting material used in producing soy sauces, such as tamari, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chili Pepper
Chili peppers (also chile, chile pepper, chilli pepper, or chilli), from Nahuatl '' chīlli'' (), are varieties of the berry-fruit of plants from the genus ''Capsicum'', which are members of the nightshade family Solanaceae, cultivated for their pungency. Chili peppers are widely used in many cuisines as a spice to add "heat" to dishes. Capsaicin and related compounds known as capsaicinoids are the substances giving chili peppers their intensity when ingested or applied topically. While ''chili peppers'' are (to varying degrees) pungent or "spicy", there are other varieties of capsicum such as bell peppers (UK: peppers) which generally provide additional sweetness and flavor to a meal rather than “heat.” Chili peppers are believed to have originated somewhere in Central or South America. and were first cultivated in Mexico. After the Columbian Exchange, many cultivars of chili pepper spread around the world, used for both food and traditional medicine. This led to a ...

Gochujang
''Gochujang'' (, from Korean: , ) or red chili paste * is a savory, sweet, and spicy fermented condiment popular in Korean cooking. It is made from gochu-garu (chili powder), glutinous rice, ''meju'' (fermented soybean) powder, ''yeotgireum'' (barley malt powder), and salt. The sweetness comes from the starch of cooked glutinous rice, cultured with saccharifying enzymes during the fermentation process. Traditionally, it has been naturally fermented over years in ''jangdok'' (earthenware) on an elevated stone platform, called ''jangdokdae'', in the backyard. The Sunchang Gochujang Festival is held annually in Gochujang Village in Sunchang County, North Jeolla Province, South Korea. History It has commonly been assumed that spicy ''jang'' () varieties were made using black peppers and ''chopi'' before the introduction of chili peppers. ''Shiyi xinjian'', a mid-9th century Chinese document, recorded the Korean pepper paste as (). The second-oldest documentation of pepper p ...

Fermentation In Food Processing
In food processing, fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms—yeasts or bacteria—under anaerobic (oxygen-free) conditions. Fermentation usually implies that the action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy. The term "fermentation" sometimes refers specifically to the chemical conversion of sugars into ethanol, producing alcoholic drinks such as wine, beer, and cider. However, similar processes take place in the leavening of bread (CO2 produced by yeast activity), and in the preservation of sour foods with the production of lactic acid, such as in sauerkraut and yogurt. Other widely consumed fermented foods include vinegar, olives, and cheese. More localised foods prepared by fermentation may also be based on beans, grain, vegetables, fruit, honey, dairy products, and fish. History and prehistory Natural fermentation precedes human history. Since ancient times, h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porcelain
Porcelain () is a ceramic material made by heating substances, generally including materials such as kaolinite, in a kiln to temperatures between . The strength and translucence of porcelain, relative to other types of pottery, arises mainly from vitrification and formation of the mineral mullite within the body at these high temperatures. Though definitions vary, porcelain can be divided into three main categories: hard-paste, soft-paste, and bone china. The category that an object belongs to depends on the composition of the paste used to make the body of the porcelain object and the firing conditions. Porcelain slowly evolved in China and was finally achieved (depending on the definition used) at some point about 2,000 to 1,200 years ago; it slowly spread to other East Asian countries, then to Europe, and eventually to the rest of the world. Its manufacturing process is more demanding than that for earthenware and stoneware, the two other main types of pottery, and it ...
