Organoleptic Characteristics of Flavor Materials: March 2016


This month’s column by Judith Michalski features the live Flavorcon panelists and session held on November 15, 2015. Ingredients described include: veratraldehyde, natural; 2-acetylpyrazine, natural; γ-decalactone, natural (for more on this material, see Wright); ethyl vanillin, natural; immortelle extract (Helychrysum augustifolium DC); 3-(methylthio)decanal; 2-pentylthiophene; 1-(2-furfurylthio)propanone; and ethyl cis-4,7-octadienoate.

Listing describe applications for the given ingredients. For example, veratraldehyde, natural is suggested in: vanilla, almond, peanut, maple, strawberry, cherry, cream soda, seedy notes in berries, nut skin notes, oaky/cask notes, sweet dairy and brown flavors, among others.

Normally for each material, only common descriptors are listed. For this issue, however, all remarks have been included to show the full range of perceptions from the panel and audience. Common descriptors and applications are highlighted in boldface.

This material will also be very useful in TTB flavors to augment vanillin and ethyl vanillin.

Odor: @ 1%. Sweet, ricelike, popcornlike, corn chiplike, fried, bready, brown, grilled cornlike, toasted, tortillalike, nutty, brown, toasted grainlike, salty, slightly savory, dry and earthy.

FEMA# 2360, CAS# 706-14-9, natural

Natural occurrence: Apricot, beer, butter and tobacco.

Odor: @ 1%. Sweet, fruity, fatty, oily, “fuzzy,” peachlike, apricotlike, creamy, dairy, buttery, waxy, coconutlike, and buttery.

Taste: @ 5 ppm. Peachlike, creamy, sweet, fatty, waxy.

Possible applications: This lactone straddles the divide between fruity and dairy. A wide range of flavor types were proposed for this lactone: peach, apricot, butter, butterscotch, milk, cilantro, cucumber, guava, pina colada, mango, passion fruit, cheddar cheese and cream.

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.


Immortelle extract (Helychrysum augustifolium DC)

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.
