Ham Producers
Ham is pork from a leg cut that has been preserved by wet or dry curing, with or without smoking."Bacon: Bacon and Ham Curing" in ''Chambers's Encyclopædia''. London: George Newnes, 1961, Vol. 2, p. 39. As a processed meat, the term ''ham'' includes both whole cuts of meat and ones that have been mechanically formed. Ham is made around the world, including a number of regional specialties. In addition, numerous ham products have specific geographical naming protection. History The preserving of pork leg as ham has a long history, with traces of production of cured ham among the Etruscan civilization known in the 6th and 5th century BC. Cato the Elder wrote about the "salting of hams" in his ' tome around 160 BC. There are claims that the Chinese were the first people to mention the production of cured ham. ' claims an origin from Gaul. It was certainly well established by the Roman period, as evidenced by an import trade from Gaul mentioned by Marcus Terentius Varro in ...

Clove
Cloves are the aromatic flower buds of a tree in the family Myrtaceae, ''Syzygium aromaticum'' (). They are native to the Maluku Islands, or Moluccas, in Indonesia, and are commonly used as a spice, flavoring, or Aroma compound, fragrance in final good, consumer products, such as toothpaste, soaps, or cosmetics. Cloves are available throughout the year owing to different harvest seasons across various countries. Etymology The word ''clove'', first used in English in the 15th century, derives via Middle English , Anglo-French ''clowes de gilofre'' and Old French , from the Latin word ' "nail". The related English word ''gillyflower'', originally meaning "clove", derives via said Old French and Latin ', from the Greek "clove", literally "nut leaf". Description The clove tree is an evergreen that grows up to tall, with large leaves and crimson flowers grouped in terminal clusters. The flower buds initially have a pale hue, gradually turn green, then transition to a bright red ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Curing (food Preservation)
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable for the microbe growth that causes food spoilage. Curing can be traced back to antiquity, and was the primary method of preserving meat and fish until the late 19th century. Dehydration was the earliest form of food curing. Many curing processes also involve smoking, spicing, cooking, or the addition of combinations of sugar, nitrate, and nitrite. Meat preservation in general (of meat from livestock, game, and poultry) comprises the set of all treatment processes for preserving the properties, taste, texture, and color of raw, partially cooked, or cooked meats while keeping them edible and safe to consume. Curing has been the dominant m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrosamine
Nitrosamines (or more formally ''N''-nitrosamines) are organic compounds produced by industrial processes. The chemical structure is , where R is usually an alkyl group. Nitrosamines have a nitroso group () that are "probable human carcinogens", bonded to a deprotonated amine. Most nitrosamines are carcinogenic in animals. A 2006 systematic review supports a "positive association between nitrite and nitrosamine intake and gastric cancer, between meat and processed meat intake and gastric cancer and oesophageal cancer, and between preserved fish, vegetable and smoked food intake and gastric cancer, but is not conclusive". Chemistry The organic chemistry of nitrosamines is well developed with regard to their syntheses, their structures, and their reactions. They usually are produced by the reaction of nitrous acid () and secondary amines, although other nitrosyl sources (e.g. , , Alkyl nitrite, RONO) have the same effect: : The nitrous acid usually arises from protonation of a nit ...

Amino Acid
Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. Only these 22 appear in the genetic code of life. Amino acids can be classified according to the locations of the core structural functional groups ( alpha- , beta- , gamma- amino acids, etc.); other categories relate to polarity, ionization, and side-chain group type ( aliphatic, acyclic, aromatic, polar, etc.). In the form of proteins, amino-acid '' residues'' form the second-largest component (water being the largest) of human muscles and other tissues. Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis. It is thought that they played a key role in enabling life on Earth and its emergence. Amino acids are formally named by the IUPAC- IUBMB Joint Commi ...

Myoglobin
Myoglobin (symbol Mb or MB) is an iron- and oxygen-binding protein found in the cardiac and skeletal muscle, skeletal Muscle, muscle tissue of vertebrates in general and in almost all mammals. Myoglobin is distantly related to hemoglobin. Compared to hemoglobin, myoglobin has a higher affinity for oxygen and does not have cooperative binding with oxygen like hemoglobin does. Myoglobin consists of non-polar amino acids at the core of the globulin, where the heme group is non-covalently bounded with the surrounding polypeptide of myoglobin. In humans, myoglobin is found in the bloodstream only after Strain (injury), muscle injury. (Google books link is the 2008 edition) High concentrations of myoglobin in muscle cells allow organisms to hold their breath for a longer period of time. Diving mammals such as whales and seals have muscles with particularly high abundance of myoglobin. Myoglobin is found in Type I muscle, Type II A, and Type II B; although many older texts describe myo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potassium Nitrite
Potassium nitrite (distinct from potassium nitrate) is the inorganic compound with the chemical formula . It is an ionic salt of potassium ions K+ and nitrite ions NO2−, which forms a white or slightly yellow, hygroscopic crystalline powder that is soluble in water. It is a strong oxidizer and may accelerate the combustion of other materials. Like other nitrite salts such as sodium nitrite, potassium nitrite is toxic if swallowed, and laboratory tests suggest that it may be mutagenic or teratogenic. Gloves and safety glasses are usually used when handling potassium nitrite. Discovery Nitrite is present at trace levels in soil, natural waters, plant and animal tissues, and fertilizer. The pure form of nitrite was first made by the Swedish chemist Carl Wilhelm Scheele working in the laboratory of his pharmacy in the market town of Köping. He heated potassium nitrate at red heat for half an hour and obtained what he recognized as a new “salt.” The two compounds (potassium ni ...

Sodium Nitrite
Sodium nitrite is an inorganic compound with the chemical formula . It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic. From an industrial perspective, it is the most important nitrite salt. It is a precursor to a variety of organic compounds, such as pharmaceuticals, dyes, and pesticides, but it is probably best known as a food additive used in processed meats and (in some countries) in fish products. Uses Industrial chemistry The main use of sodium nitrite is for the industrial production of organonitrogen compounds. It is a reagent for conversion of amines into diazo compounds, which are key precursors to many dyes, such as diazo dyes. Nitroso compounds are produced from nitrites. These are used in the rubber industry. It is used in a variety of metallurgical applications, for phosphatizing and detinning. Sodium nitrite is an effective corrosion inhibitor and is used as an additive in industrial greases, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nitrite
The nitrite polyatomic ion, ion has the chemical formula . Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature. The name nitrite also refers to organic compounds having the –ONO group, which are esters of nitrous acid. Production Sodium nitrite is made industrially by passing a mixture of nitrogen oxides into aqueous sodium hydroxide or sodium carbonate solution: : : The product is purified by recrystallization. Alkali metal nitrites are thermally stable up to and beyond their melting point (441 °C for KNO2). Ammonium nitrite can be made from dinitrogen trioxide, N2O3, which is formally the anhydride of nitrous acid: :2 NH3 + H2O + N2O3 → 2 NH4NO2 Structure The nitrite ion has a symmetrical structure (C2v molecular point group, symmetry), with both N–O bonds having equal length and a bond angle of about 115°. In valence bond theory, it is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosciutto
Prosciutto ( ; ), also known as ''prosciutto crudo'', is an uncooked, unsmoked, and dry-cured ham. It is usually served thinly sliced. Several regions in Italy have their own variations of ''prosciutto crudo'', each with degrees of protected status, but the most prized are ''Prosciutto di Parma'' DOP, from Emilia-Romagna, and ''Prosciutto di San Daniele'' DOP, from Friuli-Venezia Giulia. Unlike speck ( Speck Alto Adige) from the South Tyrol region, prosciutto is not smoked. There is also a tradition of making prosciutto in southern Switzerland. In Italian, ''prosciutto'' means any type of ham, either dry-cured (''prosciutto crudo'' or simply ''crudo'') or cooked (''prosciutto cotto''), but in English-speaking countries, it usually means either Italian ''prosciutto crudo'' or similar hams made elsewhere. However, the word ''prosciutto'' itself is not protected; cooked ham may legally be, and in practice is, sold as ''prosciutto'' (usually as ''prosciutto cotto'', and from I ...

Jamón
''Jamón'' (; : ''jamones'') is a type of dry-cured ham produced in Spain. It is one of the most globally recognized food items of Spanish cuisine. It is also regularly a component of tapas. ''Jamón'' is the Spanish word for ' ham'. As such, other ham products produced or consumed in Spanish-speaking countries are also called by this name. In Spain, the term ''jamón serrano'' is sometimes used to avoid confusions. Spanish dry-cured ham comes in a wide range of prices and qualities; as of 2019, typical prices ranged from €5.00 to €75.00 per kilogram, depending on a number of points, such as length of curing time, breed of pig, or type of animal feeding. Description ''Jamón'' is typically consumed in slices, either manually carved from a pig's hind leg held on a ''jamonero'' stand using a sharp thin slicing knife, or cut from the deboned meat with a meat slicer. It is also regularly consumed in any shape in small portions. As a product, ''jamón'' is similar to P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jinhua Ham
Jinhua ham () is a type of specialty dry-cured ham named after the city of Jinhua, where it is produced, in Zhejiang province, China. The ham is used in Chinese cuisines to flavor stewed and braised foods as well as for making the stocks and broths of many Asian soup#Traditional soup bases, Chinese soups. The ham was awarded first prize in the Panama–Pacific International Exposition, 1915 Panama International Merchandise Exhibition. Production Jinhua ham is traditionally produced using the hind legs of a breed of pig native to China known as the "two ends black" (兩頭烏), which have black hair growing on their heads and hindquarters with white midsections. This breed is quick to mature; it has excellent meat quality and thin skin. Ham production begins when air temperatures drop below . The process takes approximately 8 to 10 months to complete. Ham production is separated into six stages, starting in the winter and ending the following autumn: #Meat preparation: Well ...
