Abstract
In addition, a molecular fingerprint of Grappa samples was performed by MALDI-TOF and MALDI-TOF/TOF MS, allowing the identification of molecular structures of major compounds within the non-volatile fraction of Grappa. The - 82 Da shifts on precursor ion masses due to the loss of 5-methylfuran ion also allowed the identification of some heterocyclic compounds, such as furan derivatives, formed during the Grappa aging within barrels. Overall, by integrating different mass spec techniques, we obtained a comprehensive molecular fingerprintI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
