概要
Six Iranian and seven Turkish samples of commercial gum tragacanth, and a sample of Turkish 'gum traganton', have been studied. Their nitrogen content varied from 0.17 to 0.58%. Their amino acid compositions are characterized by the presence of very large but variable proportions of hydroxyproline and substantial proportions of serine, proline and valine. The data presented may be useful for extending the current specifications for identity and purity, at present based solely on polysaccharide parameters, for gum tragacanth (E413).
