Ethyl vanillin, natural

Source: Aurochemicals

FEMA# 2464, CAS# 121-32-4, natural

Natural occurrence: This material generally is accepted as not occurring in nature but it has been tentatively identified in certain vanilla species, specifically pompon, tahitensis and fragrans. This has yet to be confirmed.

Odor: @ 1%. Sweet, creamy, vanilla, woody, caramellic, strong, vanillinlike.

Taste: @ 0.5 ppm. Sweet, creamy, rich, vanillinlike, slightly dairylike, vanillalike, woody and marshmallowlike.

Possible applications: Anywhere vanillin is used, ethyl vanillin can be used—albeit at about half the level. This material’s potential for use in natural flavors is interesting because two schools of thought exist regarding what’s natural. The purist may feel it should not be used, since its occurrence in nature has not been confirmed. Others will argue it is produced from natural materials, so it can be used. Time will tell.

Possible applications: With so many descriptors for this complex material, it’s not surprising that suggested applications for it were all over and across the board; liqueurs, berries, spices, bacon, tea, cask notes, dried fruit, maple, prune, molasses, raisin, vanilla, red wine, port, red grape, grapefruit, hazelnut and general fruit and brown flavors.
