Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food preparation. By preserving food, food waste can be reduced, which is an important way to decrease production costs and increase the efficiency of food systems, improve food security and nutrition and contribute towards environmental sustainability. For instance, it can reduce the environmental impact of food production.
In food processing, brining is treating food with brine or coarse salt which preserves and seasons the food while enhancing tenderness and flavor with additions such as herbs, spices, sugar, caramel or vinegar. Meat and fish are typically brined for less than twenty-four hours while vegetables, cheeses and fruit are brined in a much longer process known as pickling. Brining is similar to marination, except that a marinade usually includes a significant amount of acid, such as vinegar or citrus juice. Brining is also similar to curing, which usually involves significantly drying the food, and is done over a much longer time period.
Corned 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.
Food storage is a way of decreasing the variability of the food supply in the face of natural, inevitable variability. It allows food to be eaten for some time after harvest rather than solely immediately. It is both a traditional domestic skill and, in the form of food logistics, an important industrial and commercial activity. Food preservation, storage, and transport, including timely delivery to consumers, are important to food security, especially for the majority of people throughout the world who rely on others to produce their food.
Pastrami is a food originating from Romania usually made from beef brisket. Later recipes use lamb, pork, chicken or turkey. The raw meat is brined, partially dried, seasoned with herbs and spices, then smoked and steamed. Like corned beef, pastrami was originally created as a way to preserve meat before the invention of refrigeration. One of the iconic meats of Eastern European cuisine as well as American Jewish cuisine and New York City cuisine, hot pastrami is typically served at delicatessen restaurants on sandwiches such as the pastrami on rye.
Smoked meat is the result of a method of preparing red meat, white meat, and seafood which originated in the Paleolithic Era. Smoking adds flavor, improves the appearance of meat through the Maillard reaction, and when combined with curing it preserves the meat. When meat is cured then cold-smoked, the smoke adds phenols and other chemicals that have an antimicrobial effect on the meat. Hot smoking has less impact on preservation and is primarily used for taste and to slow-cook the meat. Interest in barbecue and smoking is on the rise worldwide.
Processed meat is considered to be any meat which has been modified in order to either improve its taste or to extend its shelf life. Methods of meat processing include salting, curing, fermentation, smoking, boiling, frying, and/or the addition of chemical preservatives. Processed meat is usually composed of pork or beef, but also poultry, while it can also contain offal or meat by-products such as blood. Processed meat products include bacon, ham, sausages, salami, corned beef, jerky, hot dogs, lunch meat, canned meat, chicken nuggets, and meat-based sauces. Meat processing includes all the processes that change fresh meat with the exception of simple mechanical processes such as cutting, grinding or mixing.
Pickling is the process of preserving or extending the shelf life of food by either anaerobic fermentation in brine or immersion in vinegar. The pickling procedure typically affects the food's texture and flavor. The resulting food is called a pickle, or, to prevent ambiguity, prefaced with pickled. Foods that are pickled include vegetables, fruits, mushrooms, meats, fish, dairy and eggs.
Charcuterie is a French term for a branch of cooking devoted to prepared meat products, such as bacon, ham, sausage, terrines, galantines, ballotines, pâtés, and confit, primarily from pork.
Curing salt is used in meat processing to generate a pinkish shade and to extend shelf life. It is both a color agent and a means to facilitate food preservation as it prevents or slows spoilage by bacteria or fungus. Curing salts are generally a mixture of sodium chloride and sodium nitrite, and are used for pickling meats as part of the process to make sausage or cured meat such as ham, bacon, pastrami, corned beef, etc. Though it has been suggested that the reason for using nitrite-containing curing salt is to prevent botulism, a 2018 study by the British Meat Producers Association determined that legally permitted levels of nitrite have no effect on the growth of the Clostridium botulinum bacteria that causes botulism, in line with the UK's Advisory Committee on the Microbiological Safety of Food opinion that nitrites are not required to prevent C. botulinum growth and extend shelf life..
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.
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.
Salted fish, such as kippered herring or dried and salted cod, is fish cured with dry salt and thus preserved for later eating. Drying or salting, either with dry salt or with brine, was the only widely available method of preserving fish until the 19th century. Dried fish and salted fish are a staple of diets in the Caribbean, West Africa, North Africa, South Asia, Southeast Asia, Southern China, Scandinavia, parts of Canada including Newfoundland, coastal Russia, and in the Arctic. Like other salt-cured meats, it provides preserved animal protein even in the absence of refrigeration.
Bacon and cabbage is a dish traditionally associated with Ireland. The dish consists of sliced back bacon boiled with cabbage and potatoes. Smoked bacon is sometimes used.
Food, Nutrition, Physical Activity and the Prevention of Cancer: a Global Perspective, also known as the Expert Report, was an expert report published by the World Cancer Research Fund global network in 2007. It reviewed all the evidence about the links between cancer and diet, physical activity and body fat and contains 10 recommendations for reducing cancer risk.
Salt pork is salt-cured pork. It is usually prepared from pork belly, or, more rarely, fatback. Salt pork typically resembles uncut side bacon, but is fattier, being made from the lowest part of the belly, and saltier, as the cure is stronger and performed for longer, and never smoked. The fat on the meat is necessary for the curing process as it allows the salt to soak in and preserve the meat. Salt pork is made by layering salt and thin layers of meat, then dousing it in a brine mixture once the desired size has been reached.
Cantonese salted fish is a traditional Chinese food originating from Guangdong province. It is a fish preserved or cured with salt, and was a staple food in Guangdong. It historically earned the nickname of the "poor man's food", as its extreme saltiness is useful in adding variety to the simpler rice-based dinners. Cantonese salted fish was revealed to be on the list of Group 1 known carcinogens, but was suspected and studied for its links to cancer as early as the 1960s due to the high incidence of nasopharyngeal cancer, an extremely rare type of nose and head cancer now understood to be linked to a high consumption of this dish.
Ancient diet is mainly determined by food's accessibility which involves location, geography and climate while ancient health is affected by food consumption apart from external factors such as diseases and plagues. There are still a lot of doubt about this ancient diet due to lack of evidence. Similar to what anthropologist Amanda Henry has said, there are a lot of time periods in the human history but there are only theories to answer questions on what people actually ate then. Only recently have traces been discovered in what was left of these people.
