Abstract:
Mit Hilfe der matrixsimulierenden Geschmacksverdünnungsanalyse wurden Geschmacksmodulatoren in überfermentierten Kakaobohnen lokalisiert, isoliert und anschließend mittels massenspektrometrischer Methoden (MS/MS, LC-ToF-MS) in ihrer Struktur aufgeklärt. So wurden zahlreiche geschmacksmodulierende Peptide identifiziert, die humansensorisch charakterisiert wurden. Abschließend wurden UPLC-MS/MS Methoden entwickelt um die identifizierten Peptide in Kakaobohnen unterschiedlicher Fermentationsdauer,...     »
Translated abstract:
Taste modulators were localized and isolated in overfermented cocoa beans by means of matrix simulating taste dilution analysis and subsequently their structure was elucidated by means of mass spectrometry (MS/MS, LC-ToF-MS). Thus, several taste modulating peptides were identified, which were characterized by human sensory tools. Finally, UPLC-MS/MS methods were developed to quantitate the identified peptides in cocoa beans with different fermentation times, as well as in plant-based protein hyd...     »
