Jerky From America

Jerky

Jerky is lean meat that has been trimmed of fat, cut into strips, and then dried to prevent spoilage. Normally, this drying includes the addition of salt, to prevent bacteria from developing on the meat before sufficient moisture has been removed. The word "jerky" is derived from the Spanish word charqui which is from the Quechua word ch'arki. which means to burn (meat). All that is needed to produce basic "jerky" is a low-temperature drying method, and salt to inhibit bacterial growth.

Modern manufactured jerky is normally marinated in a seasoned spice rub or liquid, and dried, dehydrated or smoked with low heat (usually under 70 °C/160 °F). Some makers still use just salt and sun-dry fresh sliced meat to make jerky. Some product manufacturers finely grind meat, mix in seasonings, and press the meat-paste into flat shapes prior to drying.

Any particular preparation or recipe for jerky typically uses only one type of meat. Around the world, meat from domestic and wild animals is used to make jerky. Meats from domestic animals include bovine, pork, goat and mutton or lamb. Wild animals including deer, elk, caribou, kudu, springbok, kangaroo, bison and moose are also used. Recently, other animals such as turkey, ostrich, salmon, alligator, tuna, emu, horse, and camel are also used.

The meat must be dried quickly, to limit bacterial growth during the critical period where the meat is not yet dry. To do this, the meat is thinly sliced, or pressed thinly, in the case of ground meat. The strips of meat are dried at low temperatures, to avoid cooking it, or overdrying it to the point where it is brittle.

Traditional jerky, made from sliced, whole muscle meat, is readily available in the United States and Canada in varying meats, brands and qualities, both as packaged and unpackaged. These products are available in nearly every convenience store, gas station, supermarket, and variety shop in those countries.

A similar, less expensive product is made with finely ground meat, mixed with flavors, then the mush is processed into thin dried strips. The finished item labeled as jerky, but with the qualifier "ground and formed". This product is widely available in general interest stores, such as supermarkets and convenience stores.

In present-day factories, large jerky ovens are made of insulated panels. Inside these low-temperature drying ovens are many heater elements and fans. The ovens have 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.

Some additional form of chemical preservative, such as sodium nitrite, is often used in conjunction with the historical salted drying procedure to prepare jerky. Smoking is the most traditional method, as it preserves, flavors, and dries the meat simultaneously. Salting is the most common method used today, as it both provides seasoning to improve the flavor as well as preserve the meat. While some methods involve applying the seasonings with a marinade, this can increase the drying time by adding moisture to the meat.
