it is a form of food preservation by allowing it to ferment or "sour" under controlled conditions. Traditional Sauerkraut is an example.
Salting and pickling are definately forms of preservation. Look at KimChee, Sauerkraut... Sauerkraut is very interesting stuff. Its only made with salt. As well as Fermentation. Cheese making is a way to preserve milk. And Many cultures ferment milk to make an alcaholic drink.
FWIW The second step in fermentation is Vinegar. The first step is alcahol. Both purified (distilled) can be used as antescepic. Many of us know the value of Vinegar its something that should be on that list of need to knows in a post apocolypic world. both can be used as preservatives both can be used to "clean" things.... Vinegar is actually alot better because its an acid that PH is excellent for killing microorganisms and molds. Alcahol not as much.
The other thing to use for preserving food and or making food edible is alkali. Native americans discovered that corn soaked in water made from the ashes of their fires was more nutritios. Those ash soaked corn kernals turn blue. Wood ash water distilled down becomes Lye. Lye and animal fat can be used to make soap. Dont know how much of each. I believe it also has applications in tanninng leather but Id have to do some digging to be sure.
Lye can be used to Turn Olives edible Dad and I could strip one Olive tree in about two hours and get eighty gallons of olives With the use of lye to remove the bitterness and finally Vinegar to nutralize the lye. Believe it or not after we were done we had to beat our friends and family off for a Jar of olives. (once the vinegar has done its job these olives are only mildly acidic).
Its also used for reconstituting dried corn to an edible kernel.... Homony. Very very interesting process Most of us are familiar with Grits. Grits that are made from homony... are different. http://en.wikipedia.org/wiki/Hominy

hard wood ash is also used to soak acorns to amke them more palatable, also when mixed with water wood ash forms a basic mild lye that can be used to wash clothing
