Salt was used a lot in early exploring- Meat would be covered in salt, and this would help preserve it.
Also pickling stuff works- like gherkins
Interestingly, sugar works as well- like with jam. That lasts for ages.
== == Acids used to preserve food include vinegars (white, red, balsamic, cider, sherry), lemon juice, lime juice, carbonic acid (carbonation), and citric acid. Alkali used to preserve food are less common, but include lye (used to preserve eggs, for example).
