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.
香草市场的波动性引起了所谓的香草危机的关注。全球对天然香草的需求不断增长,而全球供应相应减少。然而,由于基因库变异性缺乏、易受气候变化和大流行病的影响,商业作物受到灭绝的威胁。因此,迫切需要确定新的香草物种作为香草的替代来源。因此,本研究使用无定向 LC-MS/MS 代谢轮廓分析和化学计量学方法,通过注释与商业物种相关的重要风味化合物,并揭示与两个野生物种相关的独特风味描述符,展示了两种大西洋森林物种 - V. bahiana 和 V. chamissonis 的巨大生物经济潜力。这些相似性和差异性对于香草基因库改良的持续探索至关重要。在本研究中,显著且频繁与香草风味相关的化合物被注释或鉴定出来,如香草醛和对羟基苯甲醛。
