Medicated gums are currently used on the worldwide market with different indications and different active ingredient like nystatin [1], vitamin C, caffeine, fluoride[2]. Theobromine (C7H8N4O2) [TB] is a member of the family of methylxanthines (3,7-dimethylxanthine), being a bitter alkaloid. Theobromine is a water-soluble crystalline white powder. Currently this can be found in cocoa, chocolate and Camellia sinensis green tea leaves and during the decades it proves an important role in preventing caries [3;4]. For the current study, we consider important to study the interactions between the most used materials in chewing gum preparation (base gum, sweetener, etc) with Theobromine. Thermal induces interaction for binary mixture between the most used materials in chewing gum preparation and TB was studied using a TG/DTG/HF and FTIR analysis (see Fig.1)figureFig. 1: FTIR spectra for gum base, Theobromine and for binary mixture.
