Jerky

Jerkyor "charqui" is lean trimmed meat cut into strips and dehydrated to preventspoilage. Normally, this drying includes the addition of salt to prevent bacteria growth. The word "jerky" derives from theQuechuawordch'arkiwhich means "dried, salted meat".
Modern manufactured jerky is oftenmarinated, prepared with a seasonedspice rubor liquid, orsmokedwith low heat (usually under 70 °C or 160 °F). Store-bought jerky commonly includes sweeteners such as brown sugar.
Jerky is ready to eat, needs no additional preparation, and can be stored for months withoutrefrigeration. A proper protein-to-moisture content is required in the final cured product to ensure maximum shelf-life.
Many products that 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.
Jerky is made from domesticated animals as well as game animals. Jerky from domesticated animals includesbeef,pork,goatandmutton or lamband game animals such asdeer,kudu,springbok,kangaroo, andbisonare also used.Recently, other animals such asturkey,ostrich,salmon,chicken,duck,goose,shrimps,oxen,squids,octopuses,alligator,pigeon,crocodile,tuna,emu,horse,camel,lion,bear,snakeandearthwormhave entered the market.
Mostfatmust be trimmed from the meat prior to drying, as fat increases the chances of spoilage (modernvacuum packingand chemicalpreservativeshave served to help prevent these risks). The meat must be dried quickly to limitbacterialgrowth during the critical period when the meat is not yet dry. To dry quickly without 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 use exhaust ports to remove 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 sprayed with light vegetable oil to allow the meat to be removed easily. The screen trays are placed closely in layers on rolling carts and then put in the drying oven.
Chemical preservatives, such assodium nitrite, are often used to prepare jerky with the historical salted drying procedure.Smokingis the most traditional method, as it preserves, flavors, and dries the meat simultaneously.Saltingis the most common method used today, as it provides seasoning to improve the flavor as well as preserve the meat. While some methods involve applying the seasonings with amarinade, adding moisture to the meat can increase the drying time.
After the jerky is dried to the proper moisture content to prevent spoilage, it is cooled and then packaged in (often resealable) plastic bags, either nitrogen gas flushed or vacuumed packed. The sealed packages usually contain small pouches ofoxygen absorberto avoid fat oxidation. 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. For example, a 30 g (about 1 oz) portion of lean meat 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 inHong Kongat least since the 1970s. The products are purchased in kilograms, and customers choose from 10 to 20 types of meat used to make the product. Some are sold in strands instead of slices.Macauhas also opened numerous specialty shops, many of which are franchise extensions of stores from Hong Kong. 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 United States, where it is usually sold in clear plastic containers under the name "slab" jerky.
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) is responsible for that oversight. To comply with USDA regulations, poultry jerky must be heated to an internal temperature of 71 °C (160 °F) for uncured poultry or 68 °C (155 °F) 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.
A typical 30 g portion of fresh jerky contains 10–15 g of protein, 1 g of fat, and 0–3 g of carbohydrates, although some beef jerky can have a protein content above 65%.Since traditional jerky recipes use a basic salt cure,sodiumcan be a concern for some people. A 30 g serving of jerky could contain more than 600 mg of sodium, which would be about 30% of the recommendedUSRDA.
In the United States, sales of jerky snacks increased significantly, rising by 10.4% in 2024 to reach $3.29 billion. This growth can be attributed to the rising popularity of salty and spicy snacks and a growing interest in snackable protein sources. As a result, dried meat snacks have emerged as the fastest-growing category within the United States snack food market.
Ch'arki(Quechuafor dried, salted meat,Hispanicized spellingscharque, 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, producing approximately 450 tons annually. 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 incharqueadas(in Brazil) orsaladeros(in Argentina and Uruguay). In the United Statesch'arkiwas Anglicised asjerky.
