How is commercial babyfood preserved?

[Emmie412]

Started wondering the other day how commercial baby food is preserved - since there are no additives and the shelf life is very long - how is this possible? The only way I could see this happening is that if the food was heated to very high temperatures but wouldn't that destroy all the vitamins and nutrients too (and these would have to be added synthetically)? If so, organic baby food would be a joke.

Does anybody know?

You're right, very high temperatures and basically nothing good left in those jars!

I've wondered how that pouches that say they are Greek yoghurt can be yoghurt without being in a fridge. I can understand the other stuff being boiled to steralise, but yoghurt??
