. To ensure maximum shelf-life, a proper protein-to-moisture content is required in the final cured product. Many products which are sold as jerky consist of highly processed, chopped and formed meat rather than traditional sliced whole-muscle meat. These products may contain more fat, but moisture content, as in the whole-muscle product, must meet a 0.75 to 1 moisture-to protein ratio in the US.

growth during the critical period where the meat is not yet dry. To accomplish drying quickly without the use of high temperature, which would cook the meat, the meat must be sliced or pressed thin. In industrial settings, large low-temperature drying ovens with many heater elements and fans make use of exhaust ports to remove the moisture-laden air. The combination of fast-moving air and low heat dries the meat to the desired moisture content within a few hours. The raw, marinated jerky strips are placed on racks of nylon-coated metal screens which have been sprayed with a light vegetable oil to allow the meat to be removed easily. The screen trays are placed closely in layers on rolling carts which are then put in the drying oven. Chemical preservatives, such as

, this can increase the drying time by adding moisture to the meat.


Packaging

After the jerky is dried to the proper moisture content to prevent spoilage, it is cooled, then packaged in (often resealable) plastic bags, either nitrogen gas flushed or vacuumed packed. To prevent the oxidation of the fat, the sealed packages often contain small pouches of oxygen absorber. These small packets are filled with iron particles which react with oxygen, removing the oxygen from the sealed jerky package, and from an opened and resealed unfinished packet. Because of the necessary low fat and moisture content, jerky is high in protein. A 30 g (about 1 oz) portion of lean meat, for example, contains about 7 g of protein. By removing 15 g of water from the meat, the protein ratio is doubled to nearly 15 g of protein per 30 g portion. In some low moisture varieties, a 30 g serving will contain 21 g of protein, and only one g of fat. The price per unit weight of this type of jerky is higher than less-dried forms, as it takes 90 g of 99% lean meat to generate 30 g of jerky. Unpackaged fresh jerky made from sliced, whole muscle meat has been available in specialty stores in

Compared to the sealed packaged versions, unpackaged jerky has a relatively short shelf life. This type of jerky has also become very popular in convenience stores in the USA under the name "slab" jerky; it is usually sold in plexiglass containers.


Regulation

Most nations have regulations pertaining to the production of dried meat products. There are strict requirements to ensure safe and wholesome production of jerky products. Factories are required to have inspectors and sanitation plans. In the United States, the U.S. Department of Agriculture (
USDA The United States Department of Agriculture (USDA) is the federal executive department responsible for developing and executing federal laws related to farming, forestry, rural economic development, and food. It aims to meet the needs of com ...
) is responsible for that oversight. To comply with USDA regulations, poultry jerky must be heated to an internal temperature of 160 °F (71 °C) for uncured poultry or 155 °F (68 °C) for cured poultry to be considered safe Many European Union countries presently prohibit the importation of meat products, including jerky, without additional and extensive customs documentation, and further inspections.

for dried, salted meat, Hispanicized spellings ''charque, charqui, charquí'') is a dried, salted meat product. Andean charqui, made in Peru, Bolivia and Chile, is from alpaca, llama or alpaca-llama cross-breeds. Peru is the world's largest producer with approximately 450 tons produced per year. Brazilian charque is made from beef. The manufacture of charqui principally consists of salting and sun-drying. In some regions, such as in Puno, the meat is sliced before drying; in others, like Cusco, the meat is dried from whole bone-in carcass pieces, known as 'charqui completo'. It was industrialized in ''charqueadas'' (in Brazil) or ''saladeros'' (in Argentina and Uruguay). In the United States ''ch'arki'' was Anglicised as ''jerky''. When encountered by the Spanish, the
