Salting (food) in the context of "Gammon (meat)"

Salt is a mineral composed primarily of sodium chloride (NaCl). When used in food, especially in granulated form, it is more formally called table salt. In the form of a natural crystalline mineral, salt is also known as rock salt or halite. Salt is essential for life in general (being the source of the essential dietary minerals sodium and chlorine), and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and is known to uniformly improve the taste perception of food. Salting, brining, and pickling are ancient and important methods of food preservation.

Some of the earliest evidence of salt processing dates to around 6000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt works in China dates to approximately the same period. Salt was prized by the ancient Hebrews, Greeks, Romans, Byzantines, Hittites, Egyptians, and Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues, for instance triggering the El Paso Salt War which took place in El Paso in the late 1860s. Salt is used in religious ceremonies and has other cultural and traditional significance.

Meat is animal tissue, mostly muscle, that is eaten as food. Humans have hunted and farmed other animals for meat since prehistory. The Neolithic Revolution allowed the domestication of vertebrates, including chickens, sheep, goats, pigs, horses, and cattle, starting around 11,000 years ago. Since then, selective breeding has enabled farmers to produce meat with the qualities desired by producers and consumers. Meat is important to economies and cultures around the world.

Meat is mainly composed of water, protein, and fat. Its quality is affected by many factors, including the genetics, health, and nutritional status of the animal involved. Without preservation, bacteria and fungi decompose and spoil unprocessed meat within hours or days. Meat is edible raw, but it is mostly eaten cooked, such as by stewing or roasting, or processed, such as by smoking or salting.

Convenience food (also called tertiary processed food) is food that is commercially prepared (often through processing) for ease of consumption, and is usually ready to eat without further preparation. It may also be easily portable, have a long shelf life, or offer a combination of such convenient traits. Convenience foods include ready-to-eat dry products, frozen food such as TV dinners, shelf-stable food, prepared mixes such as cake mix, and snack food. Food scientists now consider most of these products to be ultra-processed foods and link them to poor health outcomes.

Bread, cheese, salted food and other prepared foods have been sold for thousands of years, but these typically require a much lower level of industrial processing, as reflected in systems such as the Nova classification. Other types of food were developed with improvements in food technology. Types of convenience foods can vary by country and geographic region. Some convenience foods have received criticism due to concerns about nutritional content and how their packaging may increase solid waste in landfills. Various methods are used to reduce the unhealthy aspects of commercially produced food and fight childhood obesity.

Processed meat is considered to be any meat that 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, and the addition of chemical preservatives. Processed meat is frequently made from pork or beef, but also poultry and others. It can contain 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.

Meat processing began as soon as people realized that cooking and salting helps to preserve fresh meat. It is not known when this took place; however, the process of salting and sun-drying was recorded in Ancient Egypt, while using ice and snow is credited to early Romans, and canning was developed by Nicolas Appert who in 1810 received a prize for his invention from the French government. Medical health organizations advise people to limit processed meat consumption as it increases risk of some forms of cancer, cardiovascular disease, and Alzheimer's disease.

Food additives are substances added to food to preserve flavor or enhance taste, appearance, or other sensory qualities. Some additives, such as vinegar (pickling), salt (salting), smoke (smoking) and sugar (crystallization), have been used for centuries to preserve food. This allows for longer-lasting foods, such as bacon, sweets, and wines.

With the advent of ultra-processed foods in the late 20th century, many additives having both natural and artificial origin were introduced. Food additives also include substances that may be introduced to food indirectly (called "indirect additives") in the manufacturing process through packaging, storage or transport.
