2-Hexyl-2-cyclopenten-1-one (isojasmone)
Source: Sigma-Aldrich
FEMA# 3552, CAS# 11050-62-7
Not naturally occurring.
Odor: @ 1%. Sweet, powdery, green, fruity, herbal, somewhat anisic, tea-like, watermelon pulp with waxiness as it dries.
Taste: @ 1 ppm. Sweet, slightly fruity, watermelon pulp, green, anisic, slightly floral and heavy.
Taste: @ 2 ppm. Waxy, fruity, pulpy, licorice, herbal, green, tea, leafy.
Possible applications: I have always associated isojasmone with watermelon notes, as it can serve a dual path: pulpy ripeness as well as the waxy rind character. Clearly, this is not the only use for this material. Most found a use in licorice flavors both black and red, teas including chai, cola or root beer flavors, spice blends and in blackberry flavors. There is potential for use in mint as well for the floral, creamy character found in some peppermints.

4-(4-Methoxyphenyl)-2-butanone, natural (anisylacetone)
Source: Sigma-Aldrich
FEMA# 2672, CAS# 104-20-1
Natural occurrence: Anise, apple brandy.
Odor: @ 1%. Sweet, floral, powdery, berry-like, anisic, vanilla, marshmallow.
Taste: @ 2 ppm. Fruity, jam-like, sweet, cotton candy, marshmallow, powdery.
Taste: @ 5 ppm. Sweet, dark berries, jam-like, anisic, powdery, cherry, helio-like.
Possible applications: Multiple red fruit flavors come to mind, such as cherry, dark berries, raspberry, grape strawberry and fruit punch. This might be a good option for cooked fruit notes, as well. Certainly, this would work in fanciful flavors like cotton candy, bubblegum, marshmallow and blue raspberry. There is a certain aspect to this material which made us think of the sweet, slightly floral nature of delicately cooked shrimp.
