Analysis of Pyrolysate of 1-L-Phenylalanine-1-deoxy-D-fructose

The thermal mass loss and pyrolysis temperatures of 1-L-phenylalanine-1-deoxy-D-fructose(PDF) were tested by thermogravimetry-differential thermal analyzer(TG-DTA).The pyrolysis behavior of PDF was identified by on-line pyrolysis and gas chromatography/mass spectrometry(Py-GC/MS) at 350,450,550,650,750 and 850℃,respectively.The results showed that the primary pyrolysis temperature of PDF was 145.91℃,and the secondary one was 170.70℃.The thermal mass loss of PDF reached about 80% at 500℃.The major pyrolytic products of PDF were aromatic hydrocarbons and heterocyclic compounds.The number of pyrolytic products of PDF increased with the rise of temperature,especially aromatic hydrocarbons.
