What You Need to Know
Xanthan's helical structure (cellulose backbone with trisaccharide side chains) creates intermolecular associations via hydrogen bonding and polymer entanglement, producing yield-stress fluids that resist particle settling. The polyanionic character from glucuronic acid residues enhances hydration and electrostatic stabilization.
Enables stable emulsions and suspensions without altering flavor at ultralow concentrations, revolutionizing shelf-stable dressings and sauces.
