To investigate the source of bitter almond taste in whole corn silage (WPCS), headspace solid-phase microextraction combined with gas chromatography–mass spectrometry (HS-SPME-GC-MS), chromatography–ion migration (HS-GC-IMS), and electronic nose (E-nose) technology were employed. The study analyzed differences volatile compounds between two WPCS samples distinct odors from same cellar. GC-IMS GC-MS identified 32 101 organic (VOCs), respectively, including aldehydes, alcohols, esters, ketones, other compounds. Three characteristic associated detected: benzaldehyde, cyanide, isocyanate. demonstrated varying sensitivities across its sensors, principal component analysis (PCA) variable importance projection (VIP) revealed that W5S (nitrogen oxides) could differentiate odors. This finding was consistent results, which 34 nitrogen-containing heterocyclic abnormal sample, accounting for 77% total In summary, significant aroma composition observed almond-flavored These primarily attributed to changes compounds, serve as indicators identifying silage.
