How does pickling preserve foods?
It does both, but not completely.During fermentation of pickled vegetables, the bacteria (especially useful lactic bacteria) convert the sugars into lactic acid (and other organic acids) that kills some other bacteria, and stops others from reproducing. During pickling process usually are added some herbs and spices (such as mustrard seed or garlic) that have antimicrobial properties, and almost always is added salt, that also kills bacteria (very high levels of salt may even sterilize the…
it is acidic so it would significantly retard bacteria growth. Using vinegar to preserve food is called pickling. It usually involves removing water from the food by soaking it in a brine (salt water) solution and then allowing the food to soak the vinegar back into it. Many foods can be pickled such as fish (herring) and cucumbers.
Pickling alters the taste of foods permanently by soaking them in a solution that changes their flavor but allows them to be preserved for a longer period of time. Pickling can only be used for foods that will be used pickled. Once you have pickled something, you cannot substitute it for a fresh ingredient in a recipe.
Sugar is used to preserve fruits as jam/jelly. Salt is used to preserve foods such as fish and meats like bacon.

Sauerkraut is essentially pickled cabbage.
ok.. pickling food makes it where it doesn't spoil quickly unless left opened for long periods of time. But pickling also means you use vinegar (usually) to pickle the stuff you're pickling which means there's a lot of salt content. Salt is bad for you, but it does keep things fresh. It's good and bad.
