Effect of trans-2-hexenal on the growth of Aspergillus flavus in relation to its concentration, temperature and water activity.
OBJECTIVE
The antifungal activity of trans-2-hexenal on Aspergillus flavus in a model system in relation to its concentration, incubation temperature and aw was assessed.


RESULTS
A model describing the antifungal activity of the aldehyde in relation to these variables was obtained.


CONCLUSIONS
According to this model, the inhibition of A. flavus was weakly dependent on the incubation temperature (at least within the range of values considered) and strongly affected by the trans-2-hexenal concentration and aw, which showed a remarkable synergistic effect.


CONCLUSIONS
Trans-2-hexenal proved to be a molecule with remarkable antimicrobial properties, even when added in closed systems at low concentration.
