GC × GC‐TOF MS and Sensory Profiling of Aroma Compounds in Magnolia Species: Effects of Processing Methods on Volatile Retention in M. wufengensis

open access: yesFlavour and Fragrance Journal, EarlyView.
The first comparative analysis of Magnolia scents reveals that M. wufengensis is characterised by a high aldehyde content, exhibiting a fresh, sweet, and fruity fragrance profile. Furthermore, freeze‐drying preserves 6.7 times more 2‐nonenal compared to shade‐drying, highlighting its superior efficacy in retaining key volatile compounds.
