Shelf life in the context of "Processed meat"

Food spoilage is the process whereby food becomes unsuitable to ingest by a person; it is a matter of food safety. Bacteria and various fungi are the causes of spoilage, and can create serious consequences for consumers, but there are preventive measures that can be taken. The precise cause of the process is due to many outside factors as a side-effect of the type of product it is, as well as how the product is packaged and stored.

Food spoilage is the reason for food preservation, to extend shelf life. Meat is processed, food is frozen, and food is canned. Due to spoilage, one-third of the world's food produced for human consumption is lost every year.

Pork is the culinary name for the meat of the pig (Sus domesticus). It is the second most commonly consumed type of meat worldwide, following poultry, with evidence of pig husbandry dating back to 8000–9000 BCE.

Pork is eaten both freshly cooked and preserved; curing extends the shelf life of pork products. Ham, gammon, bacon, and pork sausage are examples of preserved pork. Charcuterie is the branch of cooking devoted to prepared meat products, many from pork.

Food packaging is a packaging system specifically designed for food and represents one of the most important aspects among the processes involved in the food industry, as it provides protection from chemical, biological and physical alterations. The main goal of food packaging is to provide a practical means of protecting and delivering food goods at a reasonable cost, while meeting the needs and expectations of both consumers and industries. Additionally, current trends like sustainability, environmental impact reduction, and shelf-life extension have gradually become among the most important aspects in designing a packaging system.

White rice is milled rice that has had the husk, bran, and germ removed. This alters the flavor, texture, and appearance of the seed; helps prevent spoilage (extends its storage life); and makes it easier to digest. After brown rice is milled (hulled), it is polished, resulting in rice with a bright, white, shiny appearance. The milling and polishing processes both remove nutrients.

An unbalanced diet based on unenriched white rice leaves many people vulnerable to the neurological disease beriberi, due to a deficiency of thiamine (vitamin B₁). White rice is often enriched with some of the nutrients stripped from it during its processing. Enrichment of white rice with B₁, B₃, and iron is required by law in the United States when distributed by government programs to schools, nonprofits, or foreign countries. As with all natural foods, the precise nutritional composition of rice varies slightly depending on the variety, soil conditions, environmental conditions, and types of fertilizers.

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.

Lunch meats—also known as cold cuts, luncheon meats, cooked meats, sliced meats, cold meats, sandwich meats, delicatessens, and deli meats—are precooked or cured meats that are sliced and served cold or hot. They are typically served in sandwiches or on a tray. They can be purchased canned, pre-sliced (usually in vacuum packs), or they can be sliced to order, most often in delicatessens and charcuteries.

Lunch meats are processed meats designed for convenience. The preservatives added to extend the shelf life have been increasingly scrutinized due to potential links to certain diseases. In the US, Listeria infection is possible and has resulted in additional guidelines from the CDC for the elderly.

In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life. Pasteurization either destroys or deactivates microorganisms and enzymes that contribute to food spoilage or the risk of disease, including vegetative bacteria, but most bacterial spores survive the process.

Pasteurization is named after the French microbiologist Louis Pasteur, whose research in the 1860s demonstrated that thermal processing would deactivate unwanted microorganisms in wine. Spoilage enzymes are also inactivated during pasteurization. Today, pasteurization is used widely in the dairy industry and other food processing industries for food preservation and food safety.

An expiration date or expiry date is a previously determined date after which something should no longer be used, either by operation of law or by exceeding the anticipated shelf life for perishable goods. Expiration dates are applied to some food products and other products like infant car seats where the age of the product may affect its safe use.

The legal definition and usage of terms varies between countries and products.Different terms may be used for products that tend to spoil and those that tend to be shelf-stable. Use by is often applied to products such as milk and meat that are more likely to spoil and can become dangerous to those eating them. Such products should not be consumed past the date shown.Best before is often applied to products that may deteriorate slightly in quality, but are unlikely to become dangerous as a result, such as dried foods. Such products can be eaten after their Best before date at the discretion of the consumer. Storage and handling conditions will affect whether and when an item will spoil, so there is inherent variability in dating.
