Beef Jerky


Beef jerky is a type of snack food that is made by marinating beef in a curing solution and drying it. Meat treated in this way has a long shelf life and a unique flavor. Invention of this meat processing technology is attributed to Native Americans who smoke-dried meat to preserve it. Beef jerky is part of the rapidly growing meat snack market which experienced yearly sales of over $240 million in 1996. This growth has been attributed to the healthy aspects of beef jerky such as its high protein content and low fat level.

Beef jerky is a specific type of a more general kind of meat snack called jerky. Jerky is any type of meat, which has been cured with a salt solution and has had the moisture reduced to less than 50% of the total. It is typically brown colored and has a rough texture. Compared to unprocessed meat, it is tougher and has a more powerful flavor. This is primarily due to the flavor concentrating effect of the moisture removal process. Beef jerky is promoted as a nutritious, low calorie product, which is low in cholesterol and fat and high in protein and energy.

To increase the consumer acceptance of the product, there are many different flavors of beef jerky that are produced. One of the most common is the pepper flavored jerky. Other types include teriyaki jerky, hot styles, and barbecue styles. Hickory smoked and maple spice flavors are also produced. In addition to these flavors, other meats are used in jerky making. Currently, the most popular jerky meat after beef is turkey.


Beef jerky is thought to have originated in South America during the 1800s. The Quechua tribe, who were ancestors of the ancient Inca empire, produced a meat similar to beef jerky called ch'arki, or charqui. It was made by adding salt to strips of muscle tissue from game animals such as deer, buffalo, and elk, and allowing them to dry in the sun or over fires for extended periods of time. This method of preparation enabled the people to preserve meats during times when it was readily available and eat it when food was scarce. When the Spanish encountered this method of meat preservation, they adopted it and made it available to the rest of the world. It became a staple foodstuff for American cowboys and pioneers. Early explorers built smoke huts and hung cuts of meat over a fire to smoke cure the meat. True jerky was made when the meat was first flavored and then cured. Over the years, people discovered that the meat could be made more palatable by the addition of various spices.

Raw Materials

The meat and a curing solution are all the components needed for making meat jerky. The primary starting material for making jerky is the meat. For the best tasting jerky, the beef used is range fed, 100% premium, visually lean, United States Department of Agriculture (USDA) inspected, flank steak. There are some manufacturers who produce a slightly different textured beef jerky using ground beef. In most cases, it requires over five pounds of meat to produce one pound of jerky. While most meat jerky is made using beef, various other types of meat are also used. Turkey has become popular because it is perceived as a healthier alternative to beef. It produces a jerky that is not as tough as beef jerky. Pork is another meat that is made into jerky. This jerky has a slightly different taste.

The curing solution is used to provide a better taste and a longer shelf life for the beef jerky. It is also responsible for the final color of the product. The cure solution also has an antimicrobial effect, which prevents the growth of harmful bacteria. A typical curing solution is composed of water and salt plus sodium nitrite. The salt has a dehydrating effect on the meat. The sodium nitrite helps to retard the development of rancidity and stabilizes the color. Sodium ascorbate may also be added to increase the pink color of the meat.

The curing solution is mixed with a brine, which is an aqueous solution of seasonings, spices, salt, sugars, and phosphates. Some common flavorants used include soy sauce, lemon juice, pepper, monosodium glutinate (MSG), or garlic powder. Worcestershire sauce is also used, as is teriyaki sauce. The sugars that are used to provide a level of sweetness include sucrose, dextrose, brown sugar, and dark corn syrup. Flavored salts such as hickory salt or onion salt are also included in the brine. Sodium phosphates may also be used. Some manufacturers use a material known as liquid smoke, which is made by dissolving smoke in water. This material gives the meat a smoke cooked taste without requiring smoke during cooking. Since jerky is very tough, a tenderizing agents such as polyphosphates or papin enzyme can be included. The use of these materials is limited however, because it increases the amount of time required for drying.

The Manufacturing

While many different techniques can be used to make jerky, each have the primary steps of preparing the meat, soaking it in a curing solution, and cooking it until it is dried.

Quality Control

In any food processing facility, quality control is extremely important. Governmental regulations require that certain minimum standards be met for any raw material that will be used. Meats in particular are heavily regulated because the use of poor quality meat represents a significant health risk. Most companies will use only high quality meat to assure their jerky is of similar quality. All the initial raw materials are checked prior to processing for such things as such as pH, percentage moisture, odor, taste, and appearance.

The cured meat is cut, spread out on trays, and dried into a jerky.

Additionally, sanitation procedures for the production equipment are also subject to regulation. Since the beef jerky will be ingested, steps must be taken to ensure that it will have an appealing taste and be free from contamination. For this reason, tests similar to the ones run on the initial raw materials are performed on the final product.

The Future

It is anticipated that future developments in meat jerky processing will be found in a few key areas. An important area of product development is focused on developing new flavors of meat jerky. This involves creating different recipes and using various kinds of meats. To further boost the image of meat jerky as a healthy snack, manufacturers will attempt to find ways of reducing the salt content of the final product. In the manufacturing area, a more continuous process is being developed. These techniques should result in more consistent product produced in a much shorter time period. Also, environmental concerns should lead to the development of waste-minimizing technologies.
