The fresh vanilla fruit is actually tasteless, it must be fermented to show the special aroma of vanilla. This is how the synthetic vanilla smell comes from. Eugenol is extracted from clove oil and then transformed into vanillin. The vanilla smell of this substance is very fake, because vanilla contains as many as 50 flavor substances. Fortunately, people later discovered that a substance called coumarin can alleviate the irritation of vanillin. The extraction of coumarin is easy, and there are many in alfalfa. As a result, the two began to act as golden partners, giving us a taste of vanilla.
