Formation of Pyrazines by Chitin Pyrolysis

摘要: Chitin, poly-β-(1–4)-N-acetyl-D-glucosamine, was heated at 300-500°C for 5-60 min to examine the potential of pyrazine formation from chitin pyrolysis. 2-Methyl-, 2,3-dimethyl- and 2,3,5-trimethyl-pyrazine were formed 300°C additionally, 2,5-dimethylpyrazine found with increasing pyrolysis temperature up 500°C. During 60 more than twice as much 2,3,5-trimethylpyrazine developed. Thus, altering time could be useful development certain pyrazines that have food flavor applications.
