what are the ingredients in each? do they have preservatives other than salt?

The only preservative used in caviar is salt.

Are these tins or jars? It describes jars but shows pics of tins.

I think they are in glass jars with metal top.

There was no indication on the packaging that the caviar was pasteurized, however, all four jars were vacuumed sealed. I'm sorry I can't give any better information than that. I can add, though, that all the caviar was delicious!
