It kind of is natural: tomatoes, vinegar, and salt all have anti-microbial properties. The rest of the ingredients are sugars and flavors. No preservatives needed, in this product at least (Heinz).

- Scoundreller 7y agoAt high enough concentrations. But that's true of anything. Having a lot of salt or sugar (or any small molecule really) in something makes it impossible for cells to retain enough water to function. Which is why your sauce/jam doesn't go bad (except at the top, where a layer of condensed water doesn't have the high concentration of sugar or salt).
- swiley 7y agoHave you never bought tomatoes? They go bad faster than any other kind of fruit I’ve ever bought.
- AlexeyBrin 7y agoKetchup is not raw tomatoes! Home made tomato juice with pulp is usually boiled and canned. It can be stored up to two years.
