@JGoldman10,
I want you to think about this very carefully.
Frozen pasta, frozen anything.
What would be the reason to put preservatives of any kind in something you froze?
What is the reason people starting freezing things in the first place?
Just...think about it. Give it time to dwell in your mind.
You don't need to come back with some sort of dense reply with more questions attached.
Just think about it.....with your brain.
If you're tempted to respond, think about it some more.
