Does a gluten-free logo flag xanthan gum?
No. Only the ingredient list can match. Many gluten-free breads do list xanthan gum, and many do not.
Gums & emulsifiers

A fermentation gum printed as xanthan gum or E415.
Matches personal ingredient preferences based on label evidence; not medical, allergy, or dietary safety advice
What the label is naming
Xanthan gum is a thickener produced by fermenting sugar with Xanthomonas campestris. Labels almost always say xanthan gum. E415 is the additive code. The bare word xanthan is included because ingredient lists rarely use it for anything else.
Where it hides
Salad dressing, gluten-free bread, sauces, and plant-milks. It is a usual member of the 2% tail. A gluten-free claim on the front is not itself a xanthan match.

Questions
Is xanthan gum an emulsifier or a gum?
Preference lists usually file it with gums and emulsifiers. That is the bucket used here. It is not a safety class.
