Jerky - I am surprised that this word should be of South American Indian, then Spanish origin. I have seen the word in many stories about the explorers in North America learning to preserve meat for travel this way from the American Indians. There is another word, Pemmican, with fat and berries added to give something approaching a balanced diet during long journeys.

dried lean meat, pounded into a paste with fat and preserved in the form of pressed cakes
2 dried beef, suet, dried fruit, etc., prepared as a concentrated high-energy food, used for emergency rations, as on arctic expeditions
