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.

Spores of Penicillium digitatum ATCC 201167 transform geraniol, nerol, citral, and geranic acid into methylheptenone. Spore extracts of P. digitatum convert geraniol and nerol NAD+-dependently into citral. Spore extract also converts citral NAD+-dependently into geranic acid. Furthermore, a novel enzymatic
