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 in turn derived from the Incan 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]citation needed[. Some product manufacturers finely grind meat, mix in seasonings, and press the meat-paste into flat shapes prior to drying.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
A snack is a portion of food often smaller than a regular meal, generally eaten between meals. Snacks come in a variety of forms including packaged and processed foods and items made from fresh ingredients at home.
Traditionally, snacks were prepared from ingredients commonly available in the home. Often leftovers, cold cuts sandwiches, nuts, fruit, and the like were used as snacks. The Dagwood sandwich was originally the humorous result of a cartoon character's desire for large snacks. Beverages, such as coffee, are not generally considered snacks though they may be consumed along with snack foods. A beverage may be considered a snack if it possesses a substantive food item (e.g., strawberries, bananas, kiwis) that has been blended to create a smoothie.
