Novel Strecker degradation products of tyrosine and dihydroxyphenylalanine

Czech Journal of Food Sciences, 2001
Tyrosine was oxidised with either potassium peroxodisulphate or glyoxal. Volatile reaction products were isolated and analysed by GC/FID and GC/MS, derivatised with diazomethane and analysed by the same methods.
