You find a bottle of something - salad dressing or orange juice with a 1yr expiry date - yet it says preservative free. You look at the ingredients and all it say is orange juice, nothing else .... :confused:

But the label will usually also say once opened use within x days and store in refrigerator.

Does that mean it has no preservatives, because it is sealed? So it can have a 1yr expiry.

It may have been heat treated or ultra heat treated to kill all the bacteria and fungi. Once opened, they can enter and the food spoils as normal. I think some manufacturers put an expiry date on food 'cos people expect one, not because it suddenly goes off. Even some canned food has an expiry date even though it should still be safe to eat. It may lose flavour or texture but it shouldn't suddenly go off after the expiry date - a best before date would be better.

It's the radiation that preserves it - from half-life U235 fuel rods left over from the Chernobyl accident. Once it's opened, the radiation leaks out and then the stuff goes bad.

Where the U235 leaks TO - is anybody's guess, but you should be able to read by your own night light if you consume enough of that product.

This may also be true of "natural" foods, as they are rife to state that they are organic and natural. So are vomit and feces - but I digress.

Because it doesn't have preservatives in it. Simple.

no different from fruit preserves your grandma makes ;)
vitamin C is quite a good preservative, as long as its not open it will keep for a very long time.

If it is applied to a house, "preservative free" means the wood wii rot when damp, and borer will be staring work each xmas.

When applied to McDonalds, it means they tanalised the bun at no extra cost.
