Thanks for the link. I took a look at the wikipedia pages of the gums and they are closer to the modified celulose in the main article than to the polyphenols in the article I linked.

It's very complicated to compare, because they use other sugars and there are a thousand of details that are important, like how long are branchy the molecules are, and also a million of details that are above my chemistry knodledge level.

As a persomal prefference, I'd call that jelly instead of ice cream. (And in a bad day that I want to lie a little just to be mean, I'd call them a piece of cake.)
