Yes - as I said, pastuerized is fine, but preservatives are what you want to avoid - they can be funky compounds that will mess with your fermentation and leave weird byproducts in your finished cider. Cheers!
Another way to stop the fermentation, short of the full run, is to use Camden tablets. This will stop the action on the yeast. This should leave behind more apple flavor. The down side, in the eyes of some, will be a lesser alcohol content.
