General description

Geranic acid is a monoterpenemainly used in flavor, fragrance, cosmetics and agro-industries. In vitro studies show that geranic acid exhibits strong inhibitory activity against Fusarium graminearum and Colletotrichum graminicola, the two main fungal pathogens of maize. It may be responsible for the potent tyrosinase inhibitory activity of lemongrass (Cymbopogon citratus).

Application

Possible uses: orange, tea, mint, ripe fruit and melon notes.

Biochem/physiol Actions

Odor (neat): sweet, floral green, geranium leaf-like, woody with a citrus orange body nuance.
Taste at 20 ppm: sweet, woody, leafy, fruity body with some mouthfeel effects.

Carotenoid cleavage products--apocarotenoids--include biologically active compounds, such as hormones, pigments and volatiles. Their biosynthesis is initiated by the oxidative cleavage of C-C double bonds in carotenoid backbones, leading to aldehydes and/or ketones. This step is catalyzed by carotenoid oxygenases, which
