How to interpret ないって

Question

How to interpret ないって in the following sentence?

アイスには賞味期限がないって本当ですか？

がない looks like negative form of ある, but what is って then? Can it be a contraction of quoting particle と?

Answer 1

You are parsing this incorrectly. It is ない + って following after. In this case, the って is a contraction of というのは, and the ない goes with 賞味期限が.

So the whole sentence parses like this:

(アイスには賞味期限がない）って本当ですか？　→　Is it really true that ice cream doesn't have an expiration date?!
