Hi Cindy,
Yes, Whole Foods labels their gluten as gluten flour. Another term
you might see is vital wheat gluten. And I have a package from Bob's
Red Mill called vital wheat gluten flour. If you're ever unsure, look
at the protein, it should be very high. According to my BRM package
it has 23 grams of protein per 1/4 cup of dry gluten. (I'm vegan, we
regularly use gluten as the key ingredient in a protein food called seitan.)
FYI, to approximate bread flour you can add 1 teaspoon of gluten per
cup of unbleached flour.
Namaste
Sue
