Oh boy, that's a big thing with the gum base. I remember I was at a trade show and gobbled a few pieces of "Male Sexual Prowess" gum (Muira Puima, Maca, etc). Within 60 seconds the gum separated and crumbled and I couldn't even get the pieces out of my mouth.
Thermogum's a cool idea, but working with gum bases is a tricky devil.
