∙ 15y agoHigh-salt and high-sugar mixtures preserve food because they are absorbent relative to the internal fluid of microorganisms, causing them to shrivel up and eventually die. When a layer of a high-salt or high-sugar substance is used to preserve food, the food is protected from microbial invasions. This is a more sophisticated way to preserve food than the oldest method - simply letting it dry out. With salt and sugar, one can theoretically preserve food for decades without it being consumed by bacteria. The value of a method to reliably preserve food can hardly be understated. Prior to refrigeration, which is only about a century old, a preserve was the only way that an autumn harvest could be stored throughout harsh winters.
