What is Jerky?
"Jerky is meat that has been made lightweight by dehydration. Meat and poultry have lost about 75% of their weight after being made into jerky. Because most of the moisture is gone, the meat can be stored without refrigeration.
Jerky is a food known to exist for thousands of years. Large animals, such as bear, buffalo, deer and whales were dried as a method of preservation. Native Americans mixed dried meat with fruit and animal fat to make pemmican. The word "jerky" is thought to have come from the Spanish word "charque."
How Does Drying Meat Make it Safe?
Drying is an ancient method of preserving food. Drying is a low tech method available to anyone, and is a very effective means of storing food for long periods of time.
When food is dries, the lack of moisture makes it impossible for enzymes to activate, preventing the food from spoiling. Whether these enzymes are a result of bacterial or fungal contamination, or are naturally occurring, slowing or stopping the enzymatic action maintains the food in an edible state."
