Ethyl Vanillin
Ethyl vanillin is an aromatic aldehyde with a stronger and sweeter vanilla scent. Its aroma intensity is significantly higher than that of vanillin. It can provide a rich and long-lasting vanilla sweetness at lower dosages and is widely used in fragrance systems that require high performance.
Type
Woody
The aroma is sweet and rich, with very distinct vanilla characteristics. It has a milky sweetness and a powdery base, and is thicker and more direct than vanillin, with stronger diffusion and longevity.
Acquisition Methods
Chemical synthesis
Ethyl vanillin does not exist naturally in vanilla beans. It is synthesized entirely through a multi-step reaction of substituted guaiacol derivatives to ensure stable aroma intensity, consistency, and large-scale supply capability.
