The method the American pioneers used to store fruits and vegetables was... fruitcake!
Fruitcake contains less water than canned goods, and so is portable. It is make with loads of rum and sugar which keeps the fruit preserved.
The native american method was making pemmican, since they had no sugar and not even honey, was to
make it with dried, granulated meat mixed with animal fat and let the cooling lard seal the contents into a rawhide pouch. Analogous in some ways to
Scottish haggis (but not the wild "clockwise" haggis) or the old method of making sausage with gut casing.
