Abstract

AIMS:

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.

METHODS AND RESULTS:

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

CONCLUSION:

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.

SIGNIFICANCE AND IMPACT OF THE STUDY:

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