Representative flavour EI-MS data of (A) 2,3-pentandione; (B) linalool; (C) 2-acetyl pyridine; (D) α-methylbenzyl acetate from the NIST database. Threshold (T) set at 5% relative abundance indicated by blue dotted line. Green asterisk indicates the molecular weight matches with W–L NN predicted products. Insets show structures of NN-predicted products that are molecular weight matched with an MS fragmentation.
