Glutamicacid is an abundant amino acid that lends a characteristic umami taste to foods. In fermented foods, glutamicacid can be found as a free amino acid formed by proteolysis or as a non-proteolytic derivative formed by microorganisms. The aim of the present study was to identify different structures of glutamicacidderivatives in a typical fermented protein-based food product, soysauce. An
