Ham is pork from a leg cut that has been preserved by wet or dry curing, with or without smoking. As a processed meat, the term ham includes both whole cuts of meat and ones that have been mechanically formed.
Nitrate is a polyatomic ion with the chemical formula NO−
3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.
A preservative is a substance or a chemical that is added to products such as food products, beverages, pharmaceutical drugs, paints, biological samples, cosmetics, wood, and many other products to prevent decomposition by microbial growth or by undesirable chemical changes. In general, preservation is implemented in two modes, chemical and physical. Chemical preservation entails adding chemical compounds to the product. Physical preservation entails processes such as refrigeration or drying. Preservative food additives reduce the risk of foodborne infections, decrease microbial spoilage, and preserve fresh attributes and nutritional quality. Some physical techniques for food preservation include dehydration, UV-C radiation, freeze-drying, and refrigeration. Chemical preservation and physical preservation techniques are sometimes combined.
Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula KNO
3. It is an ionic salt of potassium ions K+ and nitrate ions NO3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). It is a source of nitrogen, and nitrogen was named after niter. Potassium nitrate is one of several nitrogen-containing compounds collectively referred to as saltpeter (or saltpetre outside the US).
Corned beef, bully beef, or salt beef in some Commonwealth countries, is salt-cured brisket of beef. The term comes from the treatment of the meat with large-grained rock salt, also called "corns" of salt. Sometimes, sugar and spices are added to corned beef recipes. Corned beef is featured as an ingredient in many cuisines.
Salting is the preservation of food with dry edible salt. It is related to pickling in general and more specifically to brining also known as fermenting and is one form of curing. It is one of the oldest methods of preserving food, and two historically significant salt-cured foods are salted fish and salt-cured meat. Vegetables such as runner beans and cabbage are also often preserved in this manner.
Smoked salmon is a preparation of salmon, typically a fillet that has been cured and hot or cold smoked.
Biltong is a form of air-dried, cured meat which originated in South Africa, and from there spread to other Southern African countries --. Various types of meat are used to produce it, ranging from beef to game meats such as ostrich or kudu. The cut may also vary being either fillets of meat cut into strips following the grain of the muscle, or flat pieces sliced across the grain. It is related to beef jerky, as both are spiced, dried meats; however, the typical ingredients, taste, and production processes may differ. Biltong is air-dried, which gives it a unique texture and taste, whereas jerky is heated to at least 160F.
The nitrite ion has the chemical formula NO−
2. 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.
Sodium nitrite is an inorganic compound with the chemical formula NaNO2. 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 fish products.
Pancetta is a salt-cured pork belly meat product in a category known as salume. In Italy, it is often used to add depth to soups and pastas.
Lebanon bologna is a type of cured, smoked, and fermented semidry beef sausage; it is not, in spite of its name, a pork-based bologna. Similar in appearance and texture to salami, it is somewhat darker in color, and is typically served as a cold cut or appetizer.
The origins of meat preservation are lost to the ages but probably began when humans began to realize the preservative value of salt. Sausage making originally developed as a means to preserve and transport meat. Primitive societies learned that dried berries and spices could be added to dried meat. The procedure of stuffing meat into casings remains basically the same today, but sausage recipes have been greatly refined and sausage making has become a highly respected culinary art.
Charcuterie is a branch of French cuisine devoted to prepared meat products, such as bacon, ham, sausage, terrines, galantines, ballotines, pâtés, and confit, primarily from pork.
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.
Potted meat is a form of traditional food preservation in which hot cooked meat is placed in a pot, tightly packed to exclude air, and then covered with hot fat. As the fat cools, it hardens and forms an airtight seal, preventing some spoilage by airborne bacteria. Before the days of refrigeration, potted meat was developed as a way to preserve meat when a freshly slaughtered animal could not be fully eaten immediately.
Cured fish is fish which has been cured by subjecting it to fermentation, pickling, smoking, or some combination of these before it is eaten. These food preservation processes can include adding salt, nitrates, nitrite or sugar, can involve smoking and flavoring the fish, and may include cooking it. The earliest form of curing fish was dehydration. Other methods, such as smoking fish or salt-curing also go back for thousands of years. The term "cure" is derived from the Latin curare, meaning to take care of. It was first recorded in reference to fish in 1743.
Fermented sausage, or dry sausage, is a type of sausage that is created by salting chopped or ground meat to remove moisture, while allowing beneficial bacteria to break down sugars into flavorful molecules. Bacteria, including Lactobacillus species and Leuconostoc species, break down these sugars to produce lactic acid, which not only affects the flavor of the sausage, but also lowers the pH from 6.0 to 4.5–5.0, preventing the growth of bacteria that could spoil the sausage. These effects are magnified during the drying process, as the salt and acidity are concentrated as moisture is extracted.
City ham is a term used in some parts of the United States for any lightly cured and/or smoked ham which must be refrigerated to preserve it. It is generally "wet cured", that is injected with or soaked in a brine solution containing high concentrations of salts. This is distinguished from country hams which are dry cured by being packed in crystalline curing salts and stored at room temperature. In parts of the U.S. where country ham is not consumed, city hams are often the only available hams and are just called ham.
Edwin Michael Foster was an American microbiologist, specializing in food microbiology. He was the president of the American Society for Microbiology (ASM) in 1970.
