By means of a combination of instrumental analytical and human-sensory methods the molecular definition of yeast extract taste was achieved. Following studies on the Maillard reaction of valuable yeast extract ingredient guanosine 5’-monophosphate resulted in the identification of several transformation products, which were identified in yeast extracts by means of LC-MS/MS. Furthermore the structural characterization of different compound classes based on the guanosine 5’-monophosphate scaffold was achieved, which were investigated by human-sensory and cell-based taste receptor assays.
The results create the scientific base for the understanding of yeast extract taste and the Maillard reaction of guanosine 5’-monophosphate. This allows the development of novel process flavours based on nucleotide rich yeast products.
