Humins formed from glucose, fructose and HMF had similar structural features as evidenced by IR spectroscopy. They differed in relative amounts of carboxylic, hydroxyl, aliphatic and aromatic functionalities. The growth mechanism during acid catalyzed hydrolysis differs from that during hydrothermal processing as evidenced by electron microscopy and kinetic modeling.
