Vanilla flavor: Species from the Atlantic forest as natural alternatives

The volatility of the vanilla market calls attention to the so-called vanilla crisis. There is a growing worldwide demand for natural vanilla with a concomitant reduction in global supply. However, commercial crops are threatened with extinction due to the lack of gene pool variability, susceptibility to climate change and pandemic diseases. Therefore, there is an urgent need to identify new Vanilla spp. as alternative sources vanilla. Therefore, using undirected LC-MS/MS metabolic profiling and chemometrics, the present study demonstrates the great bioeconomic potential of two Atlantic Forest species - V. bahiana and V. chamissonis - by annotation of important flavor compounds associated with the commercial species and reveals distinct flavor descriptors associated with both wild species. Such similarities and dissimilarities are crucial to the ongoing quest to Vanilla gene pool improvement. Compounds remarkably and frequently associated with vanilla flavor were annotated or identified in this study such as vanillin and p-hydroxybenzaldehyde.
