Why do even organic carrot juices and tomato juices have such a long shelf life?
So my dad has cancer and we've incorporated carrot juice each day into his diet.
We blend up the whole carrot rather than waste a bunch of it by juicing (hoping this is still as heathly).
Anyways, my question is, why do the pre-made ones have such a long shelf life?
Even the organic one I saw at the grocery store expired june 2013. Is there a bunch of preservatives in it? Or is it just sealed well in the glass bottle and metal lid that its in?
We are trying to avoid preservatives, but it would be so much simpler to buy pre-made.

Some may have preservative in them even if organic, but it is the canning process itself that give canned and jarred foods their long shelf life. Home grown fruit and vegetables that are properly canned at home can last for years.

The vegetable is cooked in the can long enough and at a high enough heat that any bacteria in the container is killed. In other words, the contents are not only cooked, but sterilized. And bacteria are the cause of spoilage. You can use canned carrots without fear...but the flavor will probably be somewhat dull.
