WebThe behaviour of 53 flavour compounds in Proton Transfer Reaction-Mass Spectrometry (PTR-MS) was investigated. Obtained spectra showed general rules on fragmentation patterns of alcohols, aldehydes, ketones and esters. Alcohols and aldehydes split off water while ketones hardly show any fragmentation. The mass fragments at m/z=55 and 69 are …
